RyanFulfil Agency Desk
Add sourcing, quality checks, packing, worldwide dropshipping fulfilment and order-issue support to your agency offer — without hiring a China team or operating a warehouse.
You remain responsible for sales, strategy and the client relationship. RyanFulfil performs the agreed China-side operations. We are not a turnkey agency: we do not build stores, run advertisements or act as your client’s customer-service department.
These are RyanFulfil’s own current operating figures across the whole business, not figures for this programme, which is new. The 150+ figure reflects the maintained 147-destination route table; actual eligibility for a given product and route is confirmed in the quote.
Quick answer
RyanFulfil Agency Desk is a China sourcing and dropshipping fulfilment service that an ecommerce agency can add behind its own client offer. On Co-Manage and White Label, the agency keeps the client, contract, pricing and first-line support; RyanFulfil handles the agreed sourcing, quality checks, packing, dispatch, tracking handoff and fulfilment-issue investigation.
Your agency on Co-Manage and White Label. RyanFulfil owns the seller relationship only on the separate Refer path. See the protection rules.
RyanFulfil runs the agreed China-side sourcing, receiving, checks, packing and dispatch. Your agency keeps sales, strategy and client communication. Follow the workflow.
Your agency contracts, invoices, prices and supports the client under its own brand. Provider visibility is assessed touchpoint by touchpoint; it is never promised as absolute. Read the limits.
Ecommerce agencies, Shopify specialists, consultants and operators managing client stores. New agencies without clients can begin through referral and training. Compare all four paths.
US terminology: white-label dropshipping fulfillment for agencies describes the same service as the British spelling fulfilment used across this site.
The gap in your service line
Physical-product clients eventually ask a question your agency cannot answer from a design system or an ad account. What happens next usually costs you either margin or the relationship.
The question arrives mid-project. You either learn a supply chain on your client’s money, or you go quiet on the part of the business that decides whether their product works.
One agent per client means a different quote format, a different chat thread and a different set of excuses. Nothing about it gets cheaper as you add the third store.
Your client does not separate the ads from the parcel. A run of late or wrong deliveries becomes a conversation about your agency, on a problem you did not cause and cannot see.
Hand the client to a fulfilment provider and you have solved their problem and closed your own account. The recurring work moves to somebody else’s invoice.
Agency Desk makes RyanFulfil your operating layer, not your sales competitor.
Four paths
The word “agency programme” is used for very different arrangements across this industry. Here is exactly who contracts, who invoices, who supports and who sets the price on each of ours.
You introduce. We take over.
You send us a seller. RyanFulfil contracts with them, invoices them, supports them and sets their price. You name the commission you want and it is added into the quote we issue — and disclosed there, so nothing is hidden from a client we own.
You lead. We join as the China operations team.
You own the client and set your own fees. RyanFulfil can be named as your China operations partner and works through a shared process with you. This is the default for the founding pilot, because it is the path we can support honestly today.
Your brand at the front. Our operations behind it.
You contract and invoice the client, and we work through your partner desk with branded outputs and registered-client protection. Availability depends on a passed visibility audit — some touchpoints cannot be hidden, and we will show you which before you sell it. Every white-label request gets a reply within 24 hours.

“White-label dropshipping” usually means putting a client’s logo on a generic product. That is a separate capability we also offer, and it is described under services. On this page it means something different: your agency sells and manages sourcing and fulfilment under its own client relationship and brand, while RyanFulfil performs the agreed China-side work in the background.
The operating line
Most partnerships in this industry break at the boundary, not in the middle. This is where ours sits, written down before anything goes wrong.
The commercial relationship and everything your client sees.
The China-side execution, within the scope you agree.
Building your client’s store. Running advertisements. Guaranteeing product-market fit or profit. Legal or tax advice. Unsupported customs or delivery guarantees. Acting as your client’s full end-customer service department. Counterfeit, infringing or prohibited goods, which we decline regardless of volume.
Eight steps
The same sequence whether it is the first store or the fifth. Steps three and four are the ones that decide whether the account is profitable for you.
Scope
The same operations the direct business runs, reached through your account structure instead of your client’s. Detail on any of these is on the services page.
The operations above are worth little to an agency if nobody answers. Median first reply: 23 minutes, measured across 704 client requests logged between 17 and 22 August 2026 for messages arriving inside working hours. Six in ten were answered inside the hour, and 95% of all requests — including those that landed overnight — had a reply within 24 hours.
The other half of that number, because it is the half that matters when you are the one waiting: about one in five in-hours messages still took more than half a day, and a message arriving at 10pm China time is answered the next morning, not the same evening. A first reply is also not a resolved problem. The full measurement and what it does not cover is on the FAQ.
Each linked figure opens its definition, population, period, exclusions, source and next review date in the public Proof Centre.
Non-solicitation and confidentiality
The reason agencies hesitate to introduce a fulfilment provider is the obvious one. These are the controls that answer it, and the one limit we will not pretend away.
On Co-Manage, White Label and Strategic, clients you register are recorded as yours. Our sales and operations people see the ownership status before any contact, and direct marketing suppresses protected partner clients.
On those same three paths we do not approach your registered clients to move them onto a direct account, and if one contacts us we route them back to you rather than quoting around you. Refer works the other way by design: a referred seller is our client, so we contract with them, support them and sell to them. That is the path, not an exception to it.
Your client’s products, prices, store data and sales volumes stay private. Private product research is not reused to pitch another partner or seller.
On co-managed and white-label accounts, our conversation is with you — during the pilot that means a dedicated WhatsApp thread, not a shared inbox your client can reach. Direct client contact needs your approval outside defined emergencies.
Each client store is its own record with its own invoicing allocation, so one client’s data does not surface inside another’s account.
What happens if a partner stops responding, if a client leaves your agency, or if an order is stranded mid-fulfilment is written down in advance, not improvised.
We cannot promise product exclusivity, and no fulfilment provider honestly can. Another seller can independently ask us to source the same publicly available product, and that is not a breach of your protection. What is protected is your information: your client’s identity, your negotiated pricing, your supplier work, your volumes and your research. We will not use any of it to build somebody else a competing offer.
The confidentiality position we already publish for sellers applies here too →
The multi-store record
The account structure an agency needs already exists, because one of our clients needed it first. Five sub-brand storefronts ran through a single account with one point of contact and one invoicing rhythm, and a completely new product category went live in a new market through the existing connection rather than a fresh onboarding.
Quality on two of those sub-brand lines slipped far enough that the client described it as a liability for his business, and that description was fair. We also left a daily address-correction workload as manual grind for far longer than we should have, absorbing it as effort instead of fixing the process. Both are in the public record of that account, and both are why the exception workflow above exists.
It also does not prove universal onboarding speed or a guaranteed result, and those were one operator’s own brands rather than an agency’s third-party clients — the account structure transfers, the commercial relationship is different.

Honest limits
Providers who promise total invisibility are describing marketing, not logistics. Some touchpoints can be configured to carry your brand. Others carry a carrier, a bank or a customs authority, and those cannot be rewritten by any provider. Here is the honest split, before you make a promise to a client.
Subject to the visibility audit for your specific setup.
These are the ones that end white-label promises badly.
Until we have completed a visibility audit against your integration, routes and documents, we sell you co-managed operations rather than a claim of invisibility. When the audit is done you get the specific list of what is configured and what still shows — in writing, so what you tell your client is defensible.
The audit walks your actual setup, one touchpoint at a time: how your client’s store is connected and what that connection shows in their admin; who appears as sender on every message and notification your client or their customer receives; the packing slip and anything else inside the parcel; the carrier and service on your routes, and what their tracking pages expose; the customs and export paperwork those routes require; the return address; and how money moves between your client, you and us. You get the result as two lists — configured, and still visible — and the second one is what we go through with you line by line.
What you may tell your client
Your audience reads your claim as ours. This is the list partners work from, and it is what the undertaking on the application form refers to. The left column is safe to publish; the right column is a breach of the brand rules in the partner agreement, and every entry in it is something that surfaces at exactly the wrong moment — a chargeback, a customs hold, a client asking a question you cannot answer.
| Claim type | Say this | Do not say this |
|---|---|---|
| Warehouse relationship | “Fulfilment is operated through our China supply-chain team and network.” | “We own this warehouse”, where you do not. |
| Delivery | “Estimated delivery on the quoted route, as stated on the quote.” | A fixed arrival date on any route, presented as a promise rather than an estimate. |
| Pricing | “Quoted all-in for the stated product, route and assumptions.” | “Always the cheapest in China”, or any claim to beat every price. |
| Quality | “Orders receive the agreed inspection checks before dispatch.” | “Every product is defect-free.” |
| Income | “You can add fulfilment as a paid service to your agency offer.” | Earnings described as automatic, certain or effort-free. |
| Client privacy | “Registered client and private product data are protected under the agreement.” | “Nobody else can ever source the same public product.” A public listing stays public. |
| White label | “Partner-fronted workflow. Specified technical and legal touchpoints may remain visible.” | “RyanFulfil is invisible everywhere”, and any version of that claim — before a visibility audit or after one. A passed audit tells you which touchpoints carry your brand and which still show a carrier, a customs authority or a bank. It does not make the claim true. |
This list is the working version, and it is the one to write from. The binding version is the schedule in the partner agreement you sign. Where the two ever differ, the signed agreement governs and this page is the copy that is wrong — tell us, and we will fix the page.
Money
There is no joining fee, no monthly programme fee and no minimum order commitment at launch. What you charge your client is your decision; what we charge is the net cost of doing the work.
On co-managed and white-label accounts the client contracts with you and pays you. You control the terms, the currency and the collection.
We bill you, not your client. New partners start prepaid, which is also what keeps a white-label account clean: where you have prepaid us and invoiced your client separately, our beneficiary details are not in your client’s payment records. Where money moves any other way, they can be — payment records identify who was actually paid, and no provider can change that.
The difference between our net quote and what you charge is yours. Quotes stay product-, route- and assumption-specific, so your margin is calculated on a real number.
You tell us the commission you want on the fulfilment we quote, and we add it into the quote for your client. Our guidance is 2% — that is the level that keeps your client’s landed cost genuinely competitive against buying direct from AliExpress, which is the comparison every one of their customers can make in thirty seconds.
If you are confident in the relationship, set it higher. The difference is carried by the client, so you are choosing between your margin and their price competitiveness — deliberately, with the number in front of you, rather than discovering it in a churn report. On white label the price is entirely yours and we do not see what you charge at all.
Founding-partner terms are confirmed after a fit assessment. Volume pricing follows proven aggregate activity rather than being promised for signing up.
From the partner kit. Most agencies land on the third.
A one-off onboarding or migration fee plus a monthly operations retainer, with our costs passed through at cost or shown separately. Best if you already charge retainers and your client values the management, not the parcel.
You take our net quote and add a fixed amount or a percentage. Simple, scales with volume, and gets volatile when a client needs a lot of support on a thin margin.
A setup fee, a monthly account-management retainer, a modest per-order commission, and separate project fees for samples, packaging, product changes or migration. The support cost gets paid for by the retainer instead of eroding the per-order margin.
Model the numbers on your own client with the agency margin calculator. It is arithmetic on inputs you supply — not a quote, and not a projection of what you will earn.
Referral is the one path where RyanFulfil contracts, invoices and supports the seller. That makes a referrer’s commission a fee inside a quote we issue on our own paper, so the quote says a partner fee is included. You still name the figure and still earn it — the seller simply is not surprised by it later, which protects you as much as it protects them.
Fit
The founding pilot is 5 to 10 invited partners over 90 days, with a maximum of two new client stores each to begin with. Small on purpose: we would rather run a small cohort properly than a large one badly. The cap is on how fast a partner adds new client stores during the pilot, not on how many stores an account can carry — if you are already a RyanFulfil client running several of your own brands, those stay exactly as they are.
Partner enablement
The partner kit is being built with the founding cohort, so the resources page marks honestly what exists today and what arrives on acceptance.
Service one-pager, discovery questions, a product brief a supplier can actually quote from, and a client proposal outline.
A working margin calculator that models retainer, per-order commission and hybrid side by side, and the quotation checklist that stops you promising a number you cannot hold.
Client onboarding checklist, multi-store operations checklist, migration checklist for a client leaving another agent.
A delivery-promise guide, so what your client’s checkout says matches what the route can do.
Claims and evidence guide, the approved-claims table, and objection handling for the questions clients actually ask.
Chinese New Year and peak-season planning, which is the single most predictable way a first year goes wrong.
Questions
If the answer is “it depends”, we say what it depends on. Seller-side questions about sourcing, shipping and costs are on the main FAQ.
The programme
A China sourcing and fulfilment backend built for agencies, consultants and operators that manage client stores. You keep the client relationship, the contract and the pricing. We source, check, pack, ship and investigate fulfilment problems behind you.
A dropshipping agent sources the product, checks it, packs it and ships it to the end customer one order at a time, without the seller holding stock. That is what RyanFulfil is to a direct seller — 4,000+ orders a day out of Guangzhou, on 4PX, YunTu and Wanbang routes. Agency Desk is that same operation reached through your agency’s account instead of your client’s. Nothing changes in the warehouse. What changes is who holds the contract, who invoices and whose brand is on the front, which is what lets you sell it as your own service instead of introducing your client to somebody else’s. The seller-side version of the workflow is set out step by step on how it works.
Both exist, and they are deliberately separate products. Referral means we contract with, invoice, support and price the seller, and you earn a commission that the quote discloses. White label means you own the client, the contract, the price and the first-line support, and we operate behind you. Co-Manage sits between them.
Three questions separate them: who owns the client, who invoices, and who sets the price. In an affiliate or referral arrangement the provider owns all three and pays you a commission — that is our Refer path, where you name the commission and the quote we issue to the seller discloses it. A reseller owns all three itself and buys the backend at a net price: that is Co-Manage, where we can be named as your China operations partner or left unnamed. White label is the reseller model with the provider deliberately kept behind your desk, subject to a visibility audit that tells you which touchpoints still show a carrier, a customs authority or a bank. The comparison table above sets all four out column by column.
Who holds the client contract. On Refer it is us. On Co-Manage and White Label it is you. Everything else — who invoices, who supports, who sets the price, whether we are visible — follows from that one fact. The comparison table above sets out all four columns.
No, and confusing the two produces quotes that do not add up. Private label is a product capability: your client’s logo on the goods, their box, their insert. It is a physical change with its own minimum order quantity, and it is described under custom branding. White label on this page is a service arrangement: your agency contracts, invoices, supports and prices the client while we run the China side behind you. The two are independent. You can sell private-label goods with RyanFulfil named openly, or plain neutral packing under a white-label agreement, and they are quoted separately because one is a unit cost and the other is a way of working.
On Co-Manage and White Label, you do, and clients you register are recorded as protected. On Refer, we do, and we say so plainly rather than letting a partner imply otherwise to a seller.
Your agency, on Co-Manage and White Label. RyanFulfil, on Refer. Strategic and API arrangements are custom.
On Co-Manage and White Label your agency invoices the client, the client pays you, and we invoice you. That flow is what keeps a white-label account clean: where you have prepaid us and invoiced your client separately, our beneficiary details are not in your client’s payment records. It is a consequence of how the money moves, not a promise we can make in every arrangement — payment records identify who was actually paid.
We quote our net cost for the product, route and assumptions. You set what your client pays. On Refer we set the seller’s price and include your named commission in it.
Yes — that is the model. You name the commission you want and we add it into the quote. Our guidance is 2%, which keeps the client’s landed cost competitive against buying direct. You can charge more if the relationship supports it, and you can layer a retainer, setup fee or project fees on top.
Nothing to apply, and nothing to hold the status. There is no joining fee, no monthly programme fee and no published minimum order commitment for the founding pilot. The only money that moves is for fulfilment actually performed: we quote our net cost for the product, the route and the stated assumptions, and you name the commission you want added into that quote. Guidance is 2%, which is the level that keeps your client’s landed cost competitive against buying direct. On white label you set the client price entirely and we do not see it. Founding-partner terms are confirmed after a fit assessment, and the whole money flow is set out under the commercial model.
None at launch. There is no joining fee, no monthly programme fee and no minimum order commitment published for the founding pilot. Terms are confirmed after a fit assessment, and anything that changes will be published here before it applies to you.
Not a published one. In practice the pilot is aimed at partners with at least one live client and a realistic second, because that is where the model works. Partners with no clients start on the referral path.
You need five things, and a warehouse is not one of them: a client selling a physical product, a product a supplier can quote from, a price you can stand behind once the backend cost is inside it, a delivery promise the route actually supports, and someone to run the China side. Agency Desk is the fifth. On the other four, the mistake that ends accounts is claiming capability you do not have — telling a client you own a warehouse in China when you do not is a breach of the approved claims, and it surfaces at exactly the wrong moment. “Fulfilment is operated through our China supply-chain team and network” is accurate, sells just as well, and survives the next question. The rest of the list is in the approved-claims table.
Visibility and client protection
Partner-fronted, yes. Invisible everywhere, no — and a provider who tells you otherwise is describing marketing rather than logistics. Under White Label your quotes, reports, packing slips and every client conversation carry your brand, and our operations channel is with you rather than with your client. What can still identify a China-side operator or shipper: store app or collaborator access in a store admin, the bank beneficiary and legal entity wherever money moves directly, carrier tracking events and shipment origin, customs and export documents, the return address, and any legally required disclosure. We audit every one of them against your actual setup and hand you two lists, configured and still visible, before you promise anything to a client. The full split is under white-label limits.
On Co-Manage, only if you choose to name us. On White Label, we work behind your desk — but some touchpoints can still identify a China-side operator or shipper regardless of what any provider promises. The two lists above set out exactly which.
Store app or collaborator access, bank beneficiary and legal entity on payments, carrier tracking events and shipment origin, customs and export documents, return addresses, and any legally required disclosure. We audit all of them against your specific setup and give you the list in writing.
Not without your approval, outside defined emergencies such as a safety, compliance or stranded-shipment issue where waiting would make things worse. Those exceptions are written into the partner terms rather than decided in the moment.
We route them back to you. We do not quote around you, and we do not use the contact as an opening to convert them to a direct account.
Non-solicitation and confidentiality are in the partner agreement rather than being a separate document you have to ask for. A separate NDA can be signed where your own client requires one.
Yes, and we will not pretend otherwise. A publicly listed product can be independently requested by anyone. What is protected is your information — your client’s identity, your pricing, your supplier work and your research — none of which we reuse to build somebody else an offer.
No. You can say fulfilment is operated through your China supply-chain team or network, which is accurate. Claiming ownership of facilities you do not own is a breach of the approved-claims policy and the kind of thing that surfaces at exactly the wrong moment.
WhatsApp plus the working Excel file or shared Google Sheet is the current operating layer. Each client store has its own invoicing allocation; there is no partner login to maintain, and none is promised.
Ask through the partner channel and we export or delete what is not required for accounting, customs or claims evidence. The specific retention periods are set in the signed agreement.
Operations
No. That boundary is deliberate and it predates this programme. We are the operations layer; the store, the offer and the traffic are your work, and we are not going to compete with you on them.
You do, on Co-Manage and White Label. We do not act as your client’s customer-service department. What we owe you is the evidence and the answer fast enough that you can respond well.
You take the first line with the end customer; we investigate on the China and carrier side and return the evidence. Our published seller-side guidance at the order issue centre and tracking status meanings is the same material partners work from.
Counterfeit, infringing and prohibited goods, in every case. Restricted categories — including batteries, liquids, some cosmetics and anything route-restricted — depend on the destination and the carrier, so they are checked per product and per route rather than answered in general.
Shopify and WooCommerce connect two-way automatically: orders pull in, tracking uploads back and triggers the store’s own shipping notification. TikTok Shop, eBay and Etsy work with tracking numbers sent to you to apply on your side. More detail on platform integrations.
Yes. That is the structure the multi-store case above documents, and it is the main operational reason to work through a partner account rather than opening a separate agent relationship per client.
One consolidated partner invoice with client-level and store-level allocation, so you can pass through or absorb per client without unpicking a single total.
A sample is a decision point before volume. Packaging moves up a ladder from neutral packing through logo application to custom boxes as volume justifies the minimum order quantity. Pre-stock follows proven demand rather than optimism.
Per route, from our maintained destination table, and separately from processing time. A quote states the working transit range for that route; it is not a promise about a specific parcel.
No. Route-specific estimates, never guarantees. Any partner claiming guaranteed delivery to a client is making a claim we cannot support and the approved-claims policy prohibits.
Factory closures and carrier congestion move the whole timeline, and the honest answer is to plan for it rather than absorb it. Peak-season and CNY planning is part of the partner kit, and the exception is written into the service policy rather than discovered in February.
Referral, conflicts and endings
You introduce a seller, we confirm the introduction is new, you name your commission, and it is added into the quote we issue to that seller and disclosed there. It accrues on each paid and shipped order, excluding taxes, duties and pass-through surcharges. Full rules are on the referral page.
Referral commission is counted monthly and paid within 7 days of the following month. refunds are netted from the payout, with no minimum payout threshold. If a refund is recorded after payout, refunds recorded after payout are deducted from the next monthly payout.
USD, EUR and GBP are supported payout currencies. other payout currencies may be possible subject to an agreed FX charge, confirmed before payout.
the first verifiable introduction recorded and accepted by RyanFulfil on WhatsApp wins. The record may be a complete partner registration, a partner-created WhatsApp group or the lead naming the referrer in their first message. An introduction is protected only after written acceptance. Existing clients and open conversations remain direct, and there are no retroactive claims.
Apply, yes. What you will be offered is the referral and training path until you have won a qualified client. That is not a soft no — it is the route that actually works, and partners move up from it.
No, not at launch. Account-level protection for the clients you register is real and enforceable. Territory exclusivity would be a promise we cannot police, so we are not making it.
The client can consent to move between direct, co-managed and white-label status. What we will not do is treat their departure from you as an opportunity, and what we will not do is strand their orders mid-fulfilment.
There is a documented business-continuity exception, because live orders and paying end customers do not pause while a partner goes quiet. It is written into the partner terms so nobody has to improvise it during a bad week.
Not today. Store connections are two-way on Shopify and WooCommerce, and a partner API sits under the Strategic path as a custom integration conversation rather than a shipped product we can point you at.
It depends on the product, the route and how complete the brief is — and we would rather say that than quote a number the pilot has not measured. Service-level targets are being measured during the founding pilot and will be published here once they are real.
Through the application form. It asks what you sell, how many clients and stores you run, your markets and your expected volume, and it tells you which path fits before you send it. A person reads every application; nothing is automatically accepted.
