Waterproof Bag Payment Terms: T/T, Letters of Credit and Cash Flow Timing

Deposit and balance: why 30/70 became the default

The standard structure in custom bag sourcing is a deposit on order confirmation and the balance before or shortly after shipment, and the most common split is thirty per cent and seventy. That number is not a law of nature; it is the point where two risks roughly balance. The supplier’s exposure is the material they must buy and the production capacity they must reserve before they are paid, which for a made-to-order waterproof programme is genuinely most of the cost. Your exposure is the cash committed before you have anything to inspect. Thirty per cent covers the supplier’s material commitment without funding their profit, which is why it settled there. Both the split and the eventual choice between letter of credit vs TT are risk-allocation decisions rather than conventions, which is what makes payment terms for waterproof bags genuinely negotiable rather than fixed.

Understanding that logic lets you move off it deliberately rather than by haggling, because the right deposit should be derived from what the deposit is actually securing: if your order uses stock materials and standard tooling, the supplier’s pre-payment exposure is low and a twenty per cent deposit is a reasonable ask. If it requires a new laminate in a custom colour, new cutting dies and a reserved three-week production slot, their exposure is high and thirty to fifty per cent is defensible.

The balance side has more room than buyers use. "Balance before shipment" is the supplier-preferred construction and it means paying for goods you have not inspected. "Balance against a passed inspection report and release for shipment" costs the supplier a few days and transfers a great deal of leverage to you. "Balance thirty days after bill of lading date" is better still for cash flow and is commonly achievable once you have a payment history.

Where the two sit relative to each other is the essence of letter of credit versus telegraphic transfer as a practical choice rather than a technical one: a telegraphic transfer is fast, cheap and offers you no documentary protection, while a letter of credit is slower and more expensive and offers precisely one kind of protection — that documents were presented correctly. Everything else about quality is governed by the inspection clause, not the payment clause.

The deposit–unit price trade: a lower deposit costs more per piece

This is the relationship most buyers discover late and it is worth stating plainly: deposit level and unit price move in opposite directions. A supplier who agrees to ten per cent instead of thirty is extending you roughly twenty per cent of the order value as unsecured credit for the whole production cycle, and they will price that. The premium is rarely itemised, which is exactly why it goes unnoticed — it is inside the unit price.

The arithmetic is worth doing explicitly rather than feeling. On a twenty thousand dollar order, moving from thirty to fifteen per cent frees three thousand dollars of cash for roughly the production cycle, say sixty to ninety days. If the unit price rises two per cent to secure it, that costs four hundred dollars. Whether that is a good trade depends entirely on what you can do with three thousand dollars for ninety days, and for most growing brands the answer is that the cash is worth more than the premium — but you should make the comparison rather than assume it.

The reverse also holds and is under-used. If you have cash and the supplier is small, offering a larger deposit is one of the cheapest price reductions available, because it removes a financing cost they are probably paying for at a much higher rate than you are. It is a genuinely non-adversarial negotiation: they get cheaper working capital, you get a lower unit price, and neither side gives up anything structural.

One caveat: never pay one hundred per cent in advance, whatever the discount. The moment the full amount is paid, every other clause in your agreement — inspection rights, rejection rights, delay damages — becomes a request rather than a term. The balance is the only practical enforcement mechanism most buyers have, and the cost structure behind the price is set out in our cost breakdown.

T/T in practice: charges, cut-off times and where the money sits

A telegraphic transfer is a bank-to-bank wire, and most of what goes wrong with it is mundane. Three mechanics matter. Charges: the sending bank, one or more intermediary banks and the receiving bank each take a fee, and unless you specify otherwise the receiving bank deducts them from the amount arriving — so a supplier invoiced for ten thousand dollars receives something less and asks you for the difference. The phrase "all bank charges to be borne by the remitter" solves it and costs a few dollars.

Timing: a transfer is not instant. Same-day or next-day within one currency zone is typical, two to five working days internationally is common, and anything crossing a weekend, a public holiday in either country, or a compliance review takes longer. Cut-off times matter too — a payment instructed after the sending bank’s cut-off starts the next business day, which is how a "paid on Friday" becomes a supplier asking on Wednesday.

And compliance: cross-border payments are screened. A first payment to a new beneficiary, a payment to a beneficiary whose name is close to a screened entry, or an amount that crosses a reporting threshold can be held for review without anyone telling you until you chase it. This is the single most common cause of a payment arriving late for no visible reason.

Two habits remove nearly all of it. Send the bank details in a format the supplier confirms in writing rather than reading them off an invoice, and verify any change of beneficiary details by a channel you initiate yourself — email account compromise in this industry is real, and an intercepted email changing bank details is one of the few ways to lose an entire order value outright. Then send the payment reference with the transfer so the supplier can match it to your order without a conversation.

What a letter of credit actually guarantees, and what it does not

The most expensive misconception in trade finance is that a letter of credit guarantees you receive good goods. It does not. It guarantees that the bank will pay the supplier if the supplier presents documents that comply exactly with the terms of the credit. That is a documentary guarantee, and it is valuable, but it is a completely different thing from a quality guarantee.

The consequence is worth internalising: the bank examines a bill of lading, a commercial invoice, a packing list and whatever else the credit requires. It does not examine bags. If the documents are clean and the container is full of defective product, the credit pays and your remedy lies entirely in the contract and the inspection clause. This is why an LC is not a substitute for a pre-shipment inspection, and why the two must be specified together — the certificate of inspection is one of the documents the credit can require.

What the LC genuinely gives you is leverage over presentation rather than production. If the supplier cannot ship on time, or cannot produce a clean bill of lading, or has not obtained the inspection certificate you required, the credit does not pay. That converts a timing and documentation failure into a financial consequence, which is real protection against a specific and common set of problems.

It also gives the supplier something: certainty of payment once they perform, and the ability to finance production against the credit in some markets. That is why suppliers often prefer an LC to an open account with a slow payer, and why the cost of the LC is sometimes worth bearing on their side rather than negotiated purely as your expense. The rules governing documentary credits, including the current version of the Uniform Customs and Practice, are published by the International Chamber of Commerce.

Choosing an LC type: sight, deferred, transferable and standby

Once you have decided an LC is worth its cost, the type matters more than the decision. Four types cover almost every situation a bag buyer meets, and they differ in when payment happens, whether credit can be extended onward, and what happens if performance fails.

For most buyers in this category a sight LC is the right instrument and a deferred LC is the right upgrade once there is a track record. Transferable credits are primarily relevant when you are buying through an agent rather than directly, and they are worth avoiding if you can contract with the producer instead — an extra documentary layer means an extra place for a discrepancy to occur, and discrepancies cost time and money on every presentation.

A deferred LC deserves one specific note: it is the cleanest way to buy yourself thirty to sixty days without taking the full risk of open account. The supplier is paid by the bank on a fixed date, so their risk is low and the price impact is modest, while your cash leaves later. If your constraint is cash timing rather than counterparty risk, this is usually a better answer than pushing the deposit down.

What an LC really costs: fees, discrepancies and the amendment cycle

The headline cost of a letter of credit is a set of bank fees, and they are the smaller part of the real cost. The larger parts are the internal time spent administering it and the risk and expense of discrepancies, which is where most of the pain sits.

• Issuance and advice fees, typically a fraction of a per cent of the credit value with a minimum charge, often one hundred to three hundred dollars in total for a mid-size order.
• Amendment fees each time the credit has to be changed, plus the delay while all parties agree — which is why the first draft should be right.
• Discrepancy fees charged when documents do not comply exactly, commonly fifty to one hundred and fifty dollars per presentation, plus the bank’s time.
• The cost of delay when a discrepancy holds payment: days to weeks, during which goods sit and demurrage or storage may accrue.
• Internal cost: someone must check every document against the credit, and on a first LC that is several hours of skilled attention.

Discrepancy rates are high — a substantial share of first presentations under documentary credits contain at least one discrepancy — and the common causes are trivial: a misspelled consignee name, a date inconsistent between two documents, a description that does not match the credit word for word, a document presented after the stated period. None of these mean anything about the goods, and all of them stop payment.

The mitigations are unglamorous and effective. Keep the credit simple: require only the documents you will actually use. Give generous date windows rather than tight ones. Have your supplier send draft documents to your bank before presentation, because a pre-check costs nothing compared with a discrepancy. And write the credit so the description of goods is short — every additional word is another opportunity for a mismatch.

Cost-wise, an LC usually stops being worth it below a certain order size, because the fixed fees do not scale down. As a rough guide, once the fixed cost plus internal time exceeds one to two per cent of order value, a T/T with a solid inspection clause and a retained balance is generally the better instrument. Our import compliance guide covers the documentary set that sits alongside the credit.

Documentary collection: D/P and D/A read by risk rather than by name

Documentary collection sits between an LC and open account and is worth knowing about because it is cheap and, used correctly, useful. A bank handles documents on your behalf with instructions, but makes no payment undertaking. The two variants differ by one word and several thousand dollars of risk.

Documents against payment, D/P, means the bank releases the shipping documents to the buyer only when the buyer pays. The supplier therefore retains control of the goods until payment, because without the bill of lading the goods cannot be collected — at the cost of having shipped goods that may sit unpaid at destination. Documents against acceptance, D/A, means documents are released against the buyer’s acceptance of a draft to pay at a future date, which means the buyer gets the goods before paying. D/A is materially closer to open account and should be treated as such.

The practical value of D/P is that it costs a fraction of an LC — often a flat fee rather than a percentage — while still giving the supplier a mechanism that ties documents to payment. It is a reasonable structure for a mid-size repeat order where you have some history but not enough for open account, and where the goods are not so customised that the supplier would be stranded if you refused collection.

The failure mode to understand is that collection offers no payment guarantee in either direction. If you refuse to pay, the supplier has goods at a foreign port and a problem. If the goods are wrong, you have paid to get documents and then have to pursue a claim. That is why collection works best with a pre-shipment inspection that has already passed — the inspection is the quality control, the collection is the payment discipline. Our pre-shipment inspection checklist is the instrument that makes this structure safe.

Open account, credit insurance and when each is realistic

Open account means the supplier ships and you pay later on agreed terms, typically thirty to ninety days from invoice or bill of lading date. It is the cheapest method to administer, the best for your cash flow, and the one carrying the most risk for the supplier — which is why it is earned rather than negotiated. Expect to be offered it somewhere between the third and tenth clean order, or immediately if you can offer security.

Two things unlock it early. The first is a track record: paying on time, repeatedly, without disputes, is the entire currency of this negotiation, and it is worth treating payment punctuality as a commercial asset rather than an administrative duty. The second is trade credit insurance, which covers the supplier or their bank against your default and effectively substitutes an insurer’s assessment for their own.

Credit insurance is more accessible than buyers expect and is worth examining if you want open account terms early. Premiums are typically a small fraction of a per cent of insured turnover, and for a supplier the effect is that your receivable becomes financeable. The trade credit and investment insurance industry is represented internationally by bodies such as the Berne Union, and most major exporters are already familiar with the mechanism.

Be honest about what open account does to your leverage. Once you are paying after delivery, the only sanction for a bad lot is the next order, which is a slow and imprecise instrument. That is acceptable with a supplier whose quality data you trust and intolerable with one you do not — which is the argument for earning open account gradually rather than accepting it eagerly. Our supplier audit checklist is the assessment that tells you which category a supplier is in.

Currency, FX and the moment your exposure is actually created

Currency risk in a bag programme is widely misunderstood because the exposure is created earlier than people think. It is not created when you pay. It is created when you commit to a price in a currency that is not the one you will sell in — which for most buyers is the moment the quotation is accepted, months before any money moves. Between that moment and the payment date, the rate can move against you, and the move lands entirely on your margin.

The size of the exposure is easy to underestimate: a five per cent adverse move on the currency of a fifty thousand dollar order is two thousand five hundred dollars, which for a product with a thirty per cent gross margin is the entire profit on a meaningful slice of the order. Most programmes run for years, so this is a recurring exposure rather than a one-off.

The mitigations, in order of practicality. Quote and pay in the same currency you sell in where the supplier will accept it — some will, some will not, and those that do usually price a small premium for carrying the risk themselves. Agree a currency adjustment clause that reopens price if the rate moves beyond a stated band, which keeps the base price sharp and bounds the tail risk. Or, for larger programmes, use a forward contract to fix the rate for a known payment date — the instrument is standard and the cost is the forward points, and it is the only one of the three that genuinely removes the exposure rather than moving it. Central bank and settlement background on these markets is published by the Bank for International Settlements.

One practical point that saves money: match the currency of your costs to the currency of your revenue wherever possible. If you sell in dollars, a dollar-denominated purchase with a dollar-denominated freight bill leaves you with almost no exposure at all, and that is worth more than clever hedging. The Incoterm and freight currency are set out in our shipping and logistics guide.

Mapping payment milestones to your cash flow peak

The reason payment terms deserve real attention is the shape of the cash curve. A custom waterproof bag programme has a distinctive profile: cash leaves in two or three lumps across sampling and production, and revenue arrives weeks or months later, after freight, clearance and whatever delay the season provides. The deepest point of that curve is your peak funding requirement, and it is determined far more by payment terms than by unit price.

Work it out concretely rather than as a feeling. Take the order value, add sampling charges, tooling, freight, duty and clearance, then place each payment on a timeline relative to production start and to your expected revenue date. What you will usually find is that the peak sits somewhere around shipment — deposit paid, balance paid, freight paid, duty paid, nothing yet sold — and that the gap between peak and revenue is six to fourteen weeks for most importers.

Two numbers matter from that exercise. The peak amount, which is what you must be able to fund, and the number of weeks it is tied up, which is what determines whether one order a year is comfortable and three a year is impossible. Growing businesses fail on the second number far more often than the first, and the usual cause is that payment terms were set for the first order and never revisited as volume grew.

Once you can see the curve, the levers become obvious and comparable: push the balance later, shorten the freight and clearance tail, reduce the deposit at the cost of a small price premium, or use a deferred LC to move cash out thirty days without changing the relationship. Each has a price, and comparing them on the curve is how you choose. The pricing side of the same stack is covered in our pricing strategy guide.

Four milestone structures compared

Rather than negotiating deposit percentages in the abstract, it helps to think in structures. Four patterns cover most of this category, and each has a different risk and cash profile.

The second structure is the one most buyers should aim for and it is usually achievable. It costs the supplier only the few days between inspection and loading, and it converts your balance from a payment into a lever — which is what makes every other quality clause in the agreement enforceable.

The third is under-used and worth asking about on large orders. A payment at production completion, verified by a passed in-line or final inspection, gives both sides a signal that the programme is on track, and it reduces the size of the final payment that everything depends on. Suppliers often prefer it to a single large balance because it improves their own working capital profile.

Whichever you choose, make each milestone verifiable by a document you can obtain independently. "On completion of production" is not verifiable; "on the supplier’s written completion notice accompanied by a passed inspection report referencing the order number" is. The milestones themselves belong in the contract, alongside the inspection rights and rejection remedies that give them force.

Escrow, inspection holds and release conditions

Between a Letter of credit and open account there are hybrid mechanisms that sometimes fit better than either, and they are worth knowing about even if you use them rarely. The common thread is that a neutral party holds the money and releases it when a stated condition is met.

Escrow through a third-party service releases funds when both parties confirm, or when an agreed inspection result is delivered. It is genuinely useful for a first order with an unfamiliar supplier where neither side will yield on terms, and it is expensive relative to the order value for anything small. The fees and the dispute mechanics matter more than the headline percentage, so read them.

An inspection-linked hold is simpler and often better: the balance sits unpaid until a named inspection company issues a passed report, with the report referenced in the payment clause. This is cheaper than escrow, uses an instrument you were going to pay for anyway, and has the advantage of naming the standard rather than the opinion. It is the structure most worth pushing for.

The failure mode of both is a vague release condition. "When buyer is satisfied" is not a condition and will stall. "When the named inspector issues a report showing the lot meets the agreed AQL with zero critical defects" is a condition, and it either happens or it does not. Write the condition so that a stranger could decide it.

If you sell through a marketplace, there is a further consideration worth factoring: your inbound cash cycle includes the platform’s settlement period, so the gap between paying your supplier and receiving marketplace funds is longer than it looks. Our Amazon FBA guide covers that side of the timeline.

Negotiating the payment clause without damaging the relationship

Payment terms are where otherwise sensible negotiations turn adversarial, because both sides read them as a statement of trust. The way to avoid that is to talk about risk and cost rather than trust. A supplier is not refusing a twenty per cent deposit because they distrust you; they are refusing because their material supplier requires cash and their bank charges them a rate you would find shocking. Say that out loud and the conversation becomes a problem to solve rather than a test of good faith.

Four moves reliably work. Ask what the deposit actually funds — if it is a specific material buy, offer to pay that against evidence of purchase rather than as a percentage. Offer something in exchange rather than asking for a concession: a larger deposit for a lower price, a faster approval process for later payment, a longer programme commitment for better terms. Start small and escalate by performance: agree tighter terms for the first two orders and write the improvement into the agreement so it happens automatically rather than being re-argued.

And pay on time, always, from the first order. Punctuality is the cheapest credibility available and it is the specific thing that unlocks better terms later. A buyer who has paid six invoices exactly on the due date will be offered open account terms that a buyer who pays late will never see, and no negotiating skill substitutes for that record.

If you are setting up a first programme and want terms you can plan around: MOQ 500 pieces per style, sampling in 6–10 working days with test evidence attached, bulk production 35–50 days, FOB Xiamen, and a milestone structure tied to documents you can verify. The full sequence from enquiry through sampling to bulk, including what is invoiced at each stage, is set out in the production process guide on our main site.

Frequently Asked Questions

Q1. Why is 30/70 the standard deposit structure?

Because it roughly balances two risks. Thirty per cent covers the supplier’s material commitment and reserved capacity without funding their profit, while seventy per cent remains unpaid until the goods exist.

Q2. Does a lower deposit always cost more per unit?

Usually yes. A smaller deposit means the supplier finances more of the cycle unsecured, and that is priced into the unit price rather than itemised. Expect roughly two to five per cent for a move from thirty to fifteen per cent.

Q3. Should I ever pay one hundred per cent in advance?

No. Once the full amount is paid, every other clause — inspection, rejection, delay damages — becomes a request. The retained balance is your only practical enforcement mechanism.

Q4. What does a letter of credit actually guarantee?

That the bank will pay if compliant documents are presented. It is a documentary guarantee, not a quality guarantee. The bank examines papers, not bags.

Q5. How can I make a letter of credit protect quality?

By requiring a passed inspection certificate as one of the documents the credit demands. The credit then refuses to pay if that certificate is missing, which is the mechanism that converts quality into a financial consequence.

Q6. What causes most LC discrepancies?

Trivial documentation issues: a misspelled name, inconsistent dates between documents, a goods description that does not match word for word, or presentation outside the stated period. None relate to the goods.

Q7. When does a letter of credit stop being worth the cost?

When fixed bank fees plus your own administration time exceed roughly one to two per cent of order value. Below that, a T/T with a strong inspection clause is usually better.

Q8. What is the difference between D/P and D/A?

Under D/P the buyer pays before receiving shipping documents; under D/A the buyer receives documents against a promise to pay later. D/A is much closer to open account in risk terms.

Q9. How do I get open account terms?

Earn them with a track record of punctual payment, or offer trade credit insurance so the supplier’s receivable becomes financeable. Expect it somewhere between the third and tenth clean order.

Q10. When is my currency exposure actually created?

When you commit to a price in a currency you do not sell in, not when you pay. That is usually at quotation acceptance, months before money moves.

Q11. What is the cheapest way to remove currency risk?

Match the currency of costs to the currency of revenue. If both purchase and freight are in your selling currency, there is almost no exposure to hedge at all.

Q12. What is a deferred or usance letter of credit?

A credit that pays the supplier a stated number of days after compliant presentation, commonly thirty to ninety. It buys you a credit period without taking full open account risk.

Q13. Where does my cash flow peak usually sit?

Around shipment: deposit, balance, freight, duty and clearance have all been paid and nothing has yet been sold. The gap to revenue is typically six to fourteen weeks.

Q14. What is the best payment structure for a first order?

Thirty per cent deposit with the balance released against a passed inspection report. It costs the supplier only a few days and makes every quality clause in the agreement enforceable.

Q15. Why should payment milestones be tied to documents?

Because a milestone you cannot independently verify is unenforceable. "On completion of production" is not verifiable; "on a passed inspection report referencing the order number" is.

Q16. Do bank charges matter on a telegraphic transfer?

Yes. Intermediary and receiving bank fees are often deducted from the amount arriving, so the supplier is short and asks for the difference. Specify that all charges are borne by the remitter.

Q17. How do I avoid losing money to a payment fraud?

Verify any change of beneficiary bank details through a channel you initiate yourself, never by replying to an email that announces the change. Account compromise in this industry is real and costly.

People Also Ask

What deposit should I pay a bag supplier?

Thirty per cent is the default because it covers material commitment without funding profit. Material-heavy custom programmes justify more; stock-material orders justify less.

Is a letter of credit safer than a bank transfer?

It is safer on documents, not on goods. It guarantees payment on compliant presentation, so quality still depends on a separate inspection clause.

Why does a smaller deposit raise the unit price?

Because the supplier is financing more of your production cycle unsecured. The premium sits inside the unit price rather than being itemised.

What is the difference between D/P and D/A?

D/P releases documents only on payment; D/A releases them against a promise to pay later. D/A carries much more risk for the supplier.

How do I protect quality through payment terms?

Release the balance against a passed inspection report, and under an LC make that report a required document so non-compliance stops payment.

When is my cash most tied up in an import order?

Around shipment, after deposit, balance, freight and duty are paid but before any revenue arrives — typically six to fourteen weeks of exposure.
