No. Standard safe terms are 30% deposit to start production, 30% after during-production inspection and 40% after pre-shipment inspection. Any supplier demanding 100% upfront without an inspection clause is a major red flag. For first orders, use Alibaba Trade Assurance so the payment releases only on verified shipment.
Once 100% of the payment has left your account, every single risk in the transaction shifts to you. Production delay, material substitution, quality defect, mis-shipment, regulatory non-compliance - all of these now happen to a supplier who has already been paid. The supplier's incentive to fix any of them collapses because their cash flow is no longer at stake.
A staged payment structure is not a sign of distrust. It is a sign of an experienced buyer. The most common structure at RND SOURCING is 30% deposit / 30% after during-production inspection / 40% after pre-shipment inspection, with the final 40% always paid against a passed inspection.

Three payment stages, three points of leverage, three chances to catch a problem before it leaves the country. Most well-run Chinese factories will accept this structure without discussion.
Paid against a Proforma Invoice signed by both parties. Material orders get placed, moulds get cut, the production schedule starts.
An accredited inspector confirms the line is producing against your specification. You still have leverage because the goods are only partly made.
Final payment against a passed inspection on the bulk run. The goods are containerised only after this stage clears.

A buyer paid 100% upfront for a small custom-mould order. The factory confirmed receipt of funds and started the mould. Three weeks later, the buyer's emails went unanswered for ten days. When communication resumed, the factory cited a 'production schedule reshuffle' and offered a delivery date four months later.
The buyer's leverage was zero. The money had already been spent on moulds that the factory now owned. Negotiating an alternative delivery date or a partial refund was the only realistic outcome. The buyer eventually received about 70% of the order, six weeks late, with one mould dimension out of tolerance.
The structure that would have prevented this is straightforward: 30% deposit to begin the mould, 30% at first article inspection, 40% at pre-shipment. The supplier's tooling exposure is covered by the deposit, and the buyer's leverage sits in the remaining 70% until inspection passes.
Alibaba Trade Assurance is the platform's escrow service. Your payment is held by Alibaba and released to the supplier only after verified shipment. It covers non-delivery and (partially) quality disputes, typically up to around $150,000 per order. It is the cleanest payment structure for a first order with a new supplier.
Trade Assurance has three limits. It does not cover counterfeits, IP/branding disputes or issues you discover after acceptance. Disputes require evidence - written specification, sample photos, signed acknowledgement. And it only works if you keep the order on-platform. Any supplier who asks you to switch to off-platform payment 'to save fees' is asking you to surrender your protection.

We default to 30/30/40 against inspection milestones, or to Trade Assurance for first orders. If a buyer wants a different structure, we discuss it before the Proforma Invoice is issued. The discussion is not adversarial. Most suppliers accept the standard structure because they understand that a buyer who agrees to 100% upfront is a buyer who has not thought carefully about the order.
We also accept letters of credit and on-platform escrow. We are not in a position to require them, but we recommend them when the order size and the supplier relationship make sense.
If a supplier pushes back on a standard staged structure, we treat that pushback as one of the most informative signals in the entire verification process.
Ask us to draft a payment structure for your next orderA winning online product clears four filters: (1) margin - it sells for 3-5x its landed cost; (2) demand - real, repeatable interest, not a one-week fad; (3) fulfilment - under 2 lb and non-fragile, so shipping is cheap and returns are rare; and (4) ad-worthiness - the benefit shows in a 10-second video. TikTok's 1B+ users mean a product that demos well on camera can be discovered overnight, but only if the other three filters hold. RND SOURCING scores every candidate against these four before a client sources it, so the viral product is also a profitable one.
Virality is not profit. A product can explode on social media and still lose money if the other three filters fail.

A client brought RND SOURCING a 'LED mushroom lamp' that was everywhere on TikTok. Scored against the four filters, it failed two: margin was only 3.1x landed cost, and the glass shade was fragile and broke in transit.
RND SOURCING advised passing and screened a foldable silicone collapsible bottle instead: 4.6x margin, 0.4 lb, unbreakable, and it demoed in one squeeze. The client sourced it through Yiwu.
Each filter has a number. A product weak on any one rarely survives paid acquisition.
TikTok reported 1B+ monthly active users; the margin and weight figures reflect common e-commerce profitability thresholds used by RND SOURCING when screening candidates.

Run the four filters as a scorecard before you source anything.
Quote the product, add freight and duties, divide retail price by that total. Need 3x minimum, 5x ideal.
Five-year Google Trends. Steady or rising beats a spike.
Under 2 lb and drop-test it. Fragile or heavy equals a fulfilment tax.
If the benefit is not obvious on camera, paid ads will not scale.
Passes all four? Source it. Fails one badly? Walk away, however viral.
Why winning products lose money.

RND SOURCING screens every candidate through the four-filter scorecard and quotes the true landed cost from Yiwu before you commit. We tell you plainly when a viral product is a trap and point you to the quiet winner that actually pays.
We also sanity-check the demo video, because ad-worthiness is the filter most first-time sellers skip.
Ask RND SOURCING to score your productBuild on a small-batch ladder: a prototype, then an engineering sample, then a 50-200 unit test run. Sell that test batch through a pre-sale page or pre-orders before you commit to tooling and mass production. Crowdfunding campaigns and customer pre-orders can fund the production run itself, so you are not carrying a warehouse of unproven inventory. Only scale once real orders prove the product. RND SOURCING structures this ladder in Yiwu - sampling, small-batch runs, and consolidated shipping - so clients test demand with a few hundred units, not a full container.
Inventory is the silent killer of new brands. The ladder caps your risk at every step so the most you can lose is a few hundred units.

A UK fitness brand wanted a door-mount resistance-band anchor but feared a container of dead stock. RND SOURCING built the sample in Yiwu, then ran a 120-unit test batch promoted through a $40 Spark ad on TikTok.
The batch sold out in nine days. RND SOURCING used the pre-orders to fund a 5,000-unit mass run, consolidated into one shipment.
The gap in risk between a test batch and a full container is the difference between a hiccup and a catastrophe.
Crowdfunding success rate was 41.98% per Statista (Jan 2025); the point is that pre-validated demand - via pre-orders or a test batch - de-risks the mass run.

Each run pays for the confidence to take the next, bigger step.
Prove the product can be made and meets spec at a workshop like those RND SOURCING uses in Yiwu.
50-200 units. Big enough to ship and learn; small enough to absorb if it flops.
A landing page or crowdfunding campaign funds the test batch and proves intent.
If it moves without heavy discounting, the market has spoken.
Commit tooling and a mass run only against real, paid demand. Consolidate shipping.
How brands accidentally bury themselves in stock.

RND SOURCING designs the small-batch ladder for every client: we sample in Yiwu, run the 50-200 unit test, consolidate the scaled shipment, and only tool up against paid demand.
Our job is to keep your warehouse empty until the market has paid to fill it.
Ask RND SOURCING for an inventory-light planDisguised traders refuse factory visits, cannot answer technical questions, span ten unrelated product categories, demand all money flow through their own account, and will not provide the original factory invoice. Real factories let you pay the maker directly and welcome a third-party audit.
The most common 'factory' a new importer meets on Alibaba is in fact a small trading company with a glossy catalogue, an English sales engineer and a domain they registered last year. The trading company is a perfectly legal business. The problem is only the label. Once a supplier claims to be the manufacturer, every signal they send is filtered through the buyer's expectations of a factory - capabilities, control, accountability - and the trading company has incentives that quietly diverge from those expectations.
Five behavioural tests separate the two. None of them require Chinese language or an in-person visit. All of them work from the buyer's first email to the buyer's first PO.

Each test removes one form of deception. The five together remove most of them. A real factory that wants your order will pass all five because the answers are routine to them. A trading company will fail at least two, because the answers expose the structural fact they would rather keep quiet.
The cheapest test in the set is the third: 'Can I pay the factory and pay you a separate fee?' A real factory says yes. A disguised trader says no.

A buyer was sourcing a simple kitchen tool and found a supplier on Alibaba with a clean business licence, a 6-year trading history and a catalogue covering silicone tools, glassware, electric kettles, yoga mats, pet toys, stationery and seven more categories. The buyer asked one process question: at what temperature and for how long is the silicone cured?
The supplier replied with a marketing paragraph that did not contain a single number. The buyer asked for a live video walk of the silicone line. The supplier offered a pre-recorded clip. The buyer asked whether payment could go directly to the factory. The supplier insisted that all payments had to be handled by the export department for tax efficiency.
We confirmed within an afternoon that the supplier was a Yiwu trading company without a workshop of its own.
If you have never worked with a Chinese factory before, the list of things a real factory agrees to can feel surprisingly open. They are not concessions. They are baseline expectations of any well-run manufacturer.
Walk the floor on a video call with the salesperson naming the machines. Pay the factory bank account, not the trading company's. Send your own inspector on a date the agent does not know in advance. Ask for the factory's own invoice and compare the unit cost with the trading company's commercial invoice. None of this is adversarial. All of it is how the relationship is supposed to work.

The first quote is usually the most favourable. Use it as a starting point for the five tests rather than as a signal to commit. A supplier who reacts well to the five tests is statistically likely to be a real factory. A supplier who reacts badly to two of the five is statistically likely to be a trader.
The most useful moment to run the tests is after you have a quotation but before you have sent a deposit. The tests lose half their value if you have already paid.
We work in Yiwu, where the trading-company share of the market is closer to 70% than to 10%. Knowing which kind you are talking to is therefore a routine part of our work, not a special investigation.
We disclose the supplier type in writing at the start of the relationship. If the right counterparty is a trading company - and for small mixed orders it often is - we say so. If the right counterparty is a factory, we give the factory name, the address and the live video walk on request.
The five tests are not our tests. They are the buyer's tests. We simply help the buyer run them.
Send us a supplier link and we will run the five testsThe workflow is short. You shortlist products and send the 1688 links. The agent confirms specification and price in Chinese, pays in RMB, has goods delivered to their warehouse, checks and consolidates them, then handles export and freight. You pay product cost plus commission plus freight, with no Chinese bank account involved.
Links or screenshots plus the quantity and any specification notes per item.
Specification, real MOQ, current stock and price, because listing data is often stale.
Paid to the seller's company account through the platform, not to an individual.
Domestic delivery within China, usually a few days.
Quantities reconciled against your list, photos taken, cartons merged into one shipment.
Declaration filed, packing list and commercial invoice issued, sea or air booked.

The quality of the order depends almost entirely on the quality of the brief. A list of bare links produces a list of assumptions.
Paying a 1688 seller is quick and largely irreversible, so the checks belong before the transfer, not after.
| Check | Why it matters | How |
|---|---|---|
| Listing price is current | 1688 prices change frequently and stale listings are common | Confirm in seller chat |
| Real MOQ and stock | Listed MOQ is often not the working MOQ | Ask directly in Chinese |
| Company name matches | Name mismatch appears in 22% of flagged suppliers | Compare listing entity to payee |
| Business status is active | Cancelled or revoked entities should stop the order | GSXT registry lookup |
| Packing detail | Determines carton count and freight volume | Request carton dimensions |

Anyone can forward a parcel. The reason this workflow is worth a commission is what happens between delivery and export, when a pile of unrelated cartons becomes one checked, documented shipment.
The client sent 23 1688 links across nine sellers. Four listings were out of stock and two had raised price since the screenshot, which we confirmed before any payment moved. One seller's company name did not match the payee account, so that item was dropped. The remaining goods arrived at our warehouse over eleven days and shipped as one LCL consignment.

A transparent 1688 workflow produces artefacts. If none of these exist, the process is not being run properly.
A client's list arrives as links; what goes back is a confirmation sheet with the real MOQ, current price and stock status per item, checked in Chinese with each seller before a single payment. We pay company accounts only, receive at our own Yiwu warehouse, photograph goods against the list and issue a consolidation report before the shipment is booked. Original order screenshots go to the client so the product cost is visible and our commission sits on its own line. We are not a bank or an escrow provider, so the transparency is in the paperwork rather than in in a guarantee we are not licensed to give.
