The 30% deposit and 70% balance against a bill of lading is a cash-flow compromise, not a protection mechanism. The deposit funds the factory's materials purchase; the balance is paid against a document that proves a shipment exists rather than that it conforms. A buyer asking simply for a lower deposit is asking the factory to carry more working capital, which is why it is usually refused. Structures that move the protection without moving the factory's cash position, such as a third tranche against inspection, the order funded up front and paid out in tranches, or a retention released on delivery, are materially easier to agree.
Ask a factory for better payment terms and the conversation almost always becomes an argument about the deposit percentage. That argument is usually the wrong one, because the deposit is not where your exposure is.
Where 30/70 came from
The deposit exists to fund the factory's materials purchase. A manufacturer taking a $120,000 order has to buy aluminium, or resin, or components, before making anything, and they are not going to fund that against a purchase order from a company they have never traded with. Thirty per cent is roughly what materials and tooling cost on a typical order.
The 70% balance is paid against a bill of lading because that is the document that exists at the moment the goods leave. It was chosen for timing, not for what it proves.
Neither half was designed to protect the buyer. Understanding that changes what you ask for.
What each half actually costs you
The 30%. Irrecoverable from the moment it settles. If the factory takes it and does nothing, your recourse is litigation in their jurisdiction for a sum that will not justify it. This is the number everyone negotiates and it is the smaller problem.
The 70%. Paid against a scanned bill of lading, which proves a container was loaded and shipped. It does not prove what is in the container. Buyers have paid a balance against a genuine bill of lading and received scrap. At that point 100% of the order value is gone, not 30%.
So the exposure is not the deposit. It is that the last payment is triggered by a document about logistics rather than a document about the goods.
Why asking for 20/80 usually fails
Because it asks the factory to fund more of the materials themselves. For a well-capitalised factory that is an inconvenience; for the newer ones, which is most of Vietnam and a great deal of China's second tier, it is genuinely not possible. A refusal is often a working capital fact rather than a negotiating position.
That is why the productive move is to change what triggers a payment rather than how much each payment is.
Four structures that are easier to agree
Add a third tranche against inspection. 30% deposit, 40% on a passed pre-shipment inspection, 30% against the bill of lading. The factory's cash position barely changes (they still get 70% before the goods reach you), but your largest payment is now triggered by a document about the goods rather than about a container.
Fund the whole order up front, paid out in tranches. The factory can see the full amount before they cut anything, which is a stronger assurance than a 30% deposit gives them. It is frequently an easier sell than a lower deposit, because it improves their position rather than worsening it. Their real objection to paying out in tranches is almost never suspicion; it is a belief that it delays their money, which is answered by showing them the release conditions.
Retention on delivery. 30/40/20/10, with the last 10% released 30 days after arrival. Reasonable on a first order, and worth conceding on the second. A permanent retention reads as distrust, and eventually gets priced back in.
Pay materials against evidence of purchase. Where a factory genuinely needs the deposit for materials, ask for the supplier invoice for those materials. It converts the deposit from a leap of faith into a documented step, and a factory that will not show it has told you something.
The sentence that does the work
Whatever structure you propose, lead with what the factory gets. "I would like to commit the full order value up front so you can see it is real before you start" is a better opening than "I would like to reduce the deposit", and on most orders it is also the truer description of what you are offering.
A supplier who hears they are being protected against will negotiate. One who hears their payment risk is being removed will usually ask how it works.
The message, written out
If it helps, this is the whole thing in one email. It concedes nothing on price or lead time, and it puts the factory's benefit in the second line rather than the last.
Hi [name],
For this order I would like to use a milestone payment arrangement rather than the usual 30% deposit. Practically, it means:
- I fund the full order value up front, into an account held by a licensed payment partner. You will be able to see the whole amount is committed before you start.
- It is released to you in three parts, against documents you already produce: the signed PO, the pre-shipment inspection report, and the bill of lading.
- Nothing changes about your prices, your lead times, or the documents you send me.
The reason is that it is a larger order than usual and I would rather commit the whole amount at the start than pay you in pieces as we go. It should be better for you than a 30% deposit, since the remaining 70% is already funded rather than depending on my cash flow at the end.
Happy to walk through it on a call if that is easier.
The last paragraph is the one to keep. Most objections to paying out in tranches are really objections to being asked for a favour, and an offer to explain it on a call converts a decision into a conversation.
