One of our glass bottle sourcing guides — each takes one question a buyer has to settle before ordering.
On a first glass bottle order, the safest structure for the buyer is an irrevocable letter of credit that lists an independent pre-shipment inspection certificate among its required documents; on smaller or repeat orders, a T/T deposit with the balance released against an inspection report issued before the container is sealed does similar work at lower cost. Whichever instrument you pick, confirm in writing who you are paying and what evidence releases each payment before the deposit leaves your account. Most money lost on packaging orders goes to the wrong bank account, not to a quality dispute.
How each payment method allocates risk
Every payment structure answers two things: how long your cash is out of your hands, and who holds the loss if the goods never ship or turn up wrong. A plant that quotes one unit price under two payment structures is therefore offering two different deals. Use the table as a review aid, not a ranking. A trial order and a repeat programme from the same buyer can sensibly sit on different rows.
| Structure | Who holds the risk | Tie the release of money to | Pause if |
|---|---|---|---|
| T/T, full value ahead of production | The buyer alone: failed production, rejected goods and transit loss | Signed contract, sealed sample approved, production slot confirmed, all before remitting | The specification has never been sampled or signed off, yet full advance is asked for |
| T/T deposit with balance before shipment | Divided at the balance point: buyer during the build, supplier for the remainder of the run | Pre-shipment inspection report and photos of the sealed load, in hand before you authorise the balance | Balance is due when production finishes and no inspection is scheduled first |
| T/T deposit with balance on a copy bill of lading | Passes to the buyer at loading; later damage or shortage becomes a claim, not money held back | Copy bill, invoice and packing list, while the originals travel through the banks | The copy bill is the sole proof offered and nobody inspected before sealing |
| Irrevocable sight letter of credit | Covers non-shipment and supplier default; no cover for wrong goods, since banks read paper only | A required-documents list that includes an independent pre-shipment inspection certificate | The supplier wants the inspection certificate dropped from the list to save time |
| Letter of credit with soft clauses | Swings back toward the supplier, because conditions can be impossible or wholly in its hands | Each condition matched to something the buyer can really do ahead of shipment | A certificate must come from the supplier's own agent at destination, or a named document cannot be obtained |
| Open account on a credit period | The supplier finances the buyer, holds the collection risk and charges for it | A written acceptance standard and claim window; after arrival the claim clause is your only lever | Open terms are handed out to a new buyer without any question about volume, references or payment record |
| Documentary collection (documents against payment or against acceptance) | Banks handle the papers without guaranteeing anything, so protection is procedural, not financial | Documents checked ahead of paying or accepting, and the maturity date of any acceptance written down | You are asked to accept drafts although no inspection took place |
| Escrow or platform-guaranteed milestones | A third party holds the money, so neither side faces outright default within a milestone | A milestone defined by objective evidence, for instance an inspection report or loading confirmation | No dispute procedure exists, or platform rules override the claim window in your contract |
Advance payment
Paying everything up front puts production, quality and transit risk on the buyer at once. You are funding the raw materials, the melt and the plant's working capital, and the seller risks only its reputation. That can be sensible for samples, a trial of a few pallets, or a supplier whose shipping record you have already tested. On a full production order it amounts to an interest-free loan, and the fair response is to ask for the discount a loan of that size would earn elsewhere.
Deposit and balance
A split payment divides the exposure, and the dividing line is what you actually negotiate. The deposit usually pays for materials the plant could not readily resell if you walked away; the balance pays for the value added by the time the bottles are finished. Push the balance later and risk moves to the seller, who will refuse or raise the price. A seller who accepts a very late balance with no price movement has told you something about how that price was built.
Letters of credit and documentary collection
A documentary credit swaps the counterparty's promise for a bank's undertaking, but the undertaking covers documents only. Under UCP 600, the Uniform Customs and Practice for Documentary Credits, the bank examines the papers presented and never the bottles. A credit therefore guards well against non-shipment and badly against a container of the wrong bottles.
Documentary collection is often pitched as an inexpensive middle route. With documents against payment, the bank hands over the shipping documents when you pay; with documents against acceptance, it hands them over against your promise to pay later. You get more protection than a plain advance and the seller keeps some control of the cargo, but no bank checks the contents of the container. Once you take up the documents and then find a fault, the leverage of an unpaid balance is gone.
Open account
Open account reverses the direction of the credit: the plant finances your inventory. It expects to be paid for that lending, and the charge shows up in the price line instead of as a separate item.
Five points to put in writing before the first remittance
Record these before any money moves:
- Contracting entity. The legal person that signs and carries the liability.
- Beneficiary. The account receiving the funds. Its name must match the contracting entity character for character.
- Currency. This settles who bears exchange movement between order and payment.
- Charge allocation. Whether correspondent bank deductions reduce what the seller receives. With a fixed balance figure, a deduction can prompt a claim of underpayment on a shipment that complied in every respect.
- Trigger. What has to exist before you owe a payment at all.
Raise all five in the enquiry, alongside the price. A seller asked to change payment terms once the price is agreed will treat the request as a price renegotiation. Finance teams are often asked to release a deposit within forty-eight hours of a proforma invoice arriving, which is too late to open these questions.
Verifying the bank account and the legal entity
The usual loss is a transfer to an account unconnected with the plant making the bottles. Either nobody explained the contracting structure, or a third party intercepted the payment instruction. The checks are light and only need doing once per supplier.
- Request a bank account confirmation letter on the bank's letterhead giving the account name, account number, SWIFT or BIC code and branch.
- Compare that account name with the name on the contract and on the proforma invoice.
- Ask plainly whether the account belongs to the manufacturing plant or to an affiliated trading entity. If it is an affiliate, get its relationship to the contract signatory in writing.
- Do a call-back: phone the supplier on a number from an earlier document or its own company records, never from the email carrying the bank details, and have a named person confirm the account verbally.
- Adopt a standing rule that an email alone never changes beneficiary details, however convincing the sender's domain appears.
Account takeover fraud in cross-border trade typically hijacks a live email thread and sends fresh instructions just when a payment is expected. The defence is procedure, not technology.
Know the legal entity on the far side as well. One company on the quotation, another on the invoice and a third on the bank account can be legitimate, as when a group runs a manufacturing subsidiary beside a separate export company. It is also the arrangement in which a warranty claim or an arbitration becomes hard to enforce. Ask for each entity's registration details and a brief written note of who does what. It costs nothing and spares you an expensive untangling later.
Supplier answers that justify pausing a payment
None of these proves dishonesty. Each is reason enough to hold a remittance for a day and verify.
- A deposit requested into a personal account, or one held by somebody whose surname is absent from the corporate documents. This is the clearest signal.
- New bank details arriving shortly before a scheduled payment, with no signed confirmation via a second channel. This is the classic interception pattern.
- Urgency: a price valid only if you pay today, a production slot that disappears within hours, or full payment for a first production order ahead of any approved sample. Urgency is what defeats verification. A genuine supplier with a full order book will still name the real booking deadline and accept a deposit one working day later, after the account is confirmed.
Weigh milder signals as a group. A supplier that cannot name the receiving bank, a proforma invoice with company details unlike those in earlier correspondence, reluctance to permit inspection ahead of the balance, and a shipment reference nobody can produce are each minor. Together they matter. The answer is to change the structure, not to cancel: a letter of credit calling for a pre-shipment inspection certificate turns a question of trust into a documentary one a bank can administer.
Choosing the document that releases the balance
Release the balance against a paper that could not exist had the work not been done. Ranked from the buyer's side:
- Independent pre-shipment inspection report, dated before sealing. The goods are still at the plant, so a failed inspection can halt or correct the shipment instead of merely producing a claim.
- Copy bill of lading. It proves loading, but it is issued after the point where correction is cheap, and a copy conveys no title. A seller can show one having ignored both the specification and the packing instructions.
- Arrival inspection. Strongest for you and weakest for the seller, who will normally price the added exposure.
A common combination is an inspection report plus a copy bill for the balance, with the original set passed to the buyer via the banks. For a large first order or a new relationship, a small retention held until the arrival inspection window closes is a workable compromise. It is easier to agree when the same proforma invoice also states the claim window governing its release.
A typical document set for glass packaging includes:
- proforma invoice and commercial invoice
- packing list showing the carton and pallet pattern
- full set of original bills of lading, or a telex release instruction
- inspection certificate
- certificate of origin
- beneficiary certificate, if the credit asks for one
- ISPM 15 treatment marking for wooden pallets
Decide which of these carries the payment trigger and which are administrative. If payment depends on every paper equally, the seller has as many opportunities to create a discrepancy as there are documents in the envelope.
Negotiating the deposit ratio and what the deposit covers
Argue the ratio from cost drivers, not from trust. Four carry most of the weight:
- Tooling. A new mould means the plant spends before one saleable bottle exists, so a larger deposit is defensible. Link the tooling payment to mould ownership, sample approval and a tooling register instead of folding it into the advance.
- Stock shape. Here the plant's exposure stops at materials it could sell to someone else.
- Relationship stage. A first order reasonably carries terms a repeat programme does not.
- Order value. On a small trial run the administrative cost of a credit is not worth bearing.
Deposits on glass packaging fall within a band, not on one figure, so check the ratio against your actual quotation and not against what other buyers report. The label on the deposit matters more than the percentage. A booking fee is normally non-refundable by definition, while a materials advance opens a discussion about what had been purchased when the order was cancelled. One sentence in the proforma invoice or supply agreement saying which it is has an effect out of proportion to the effort.
Comparing quotations on cash committed, not unit price
Payment-related costs are scattered: the outgoing wire fee, the correspondent bank fee, the foreign exchange spread and bill handling charges on a collection. A credit adds issuance, advising, amendment and discrepancy charges, each from a different bank. Credit insurance has a premium. Sixty or ninety days of open account credit has an implicit financing cost that the seller folds into the price.
Compare offers on total cash committed, weighted by the days it stays committed, plus fees and premium. Only then look at the price per thousand pieces. A lower price against full advance can turn out dearer than a slightly higher price with a thirty-day balance once you apply your own cost of capital and count the credit and discrepancy fees the second offer avoids.
Putting a figure on a credit period
Multiply the value financed by your annualised cost of funds, then by the days financed divided by three hundred and sixty-five. Purely to show the method with round figures: one hundred thousand in the invoiced currency, financed for ninety days at six percent, implies roughly one thousand five hundred of financing cost before fees. Add that figure to the quotation offering the longer term.
One effect never appears in the price comparison. A bank credit line committed to a letter of credit cannot be used for anything else. If you run several packaging projects at once, that limit may weigh more than the fee.
Currency
Treat currency as risk allocation first and pricing second. If the order is in the seller's currency, you bear the movement from the day the price is fixed to the day you pay, a gap that can run to months on a multi-container order. If it is in yours, the seller bears it and pads the price quietly. Often the cheapest route is a conversion rate fixed in writing when the order is placed, so the invoice converts at a stated rate whenever the balance comes due.
Keeping payment, inspection and claims on one standard
Use one standard both to release money and to define a defect. If you pay against one measure of acceptability and must later claim against another, you have paid on terms you cannot enforce, and the mismatch surfaces exactly when it costs most.
The chain reads in one line. An approved sealed sample fixes the article. The specification and sampling plan fix the acceptance standard. A pre-shipment inspection tests the run against that standard before loading. The resulting report releases the documents or the balance. The delivery term sets who bears loss from then on. The claim window and remedy ladder deal with anything found after arrival.
Four items must agree with one another, and settling them together before ordering leaves you far better placed than agreeing price first and terms afterwards:
- The payment trigger names the inspection that releases it.
- The inspection plan is the very plan cited in the claim clause.
- The delivery term passes risk at the moment of inspection. Inspecting at the plant while taking risk at arrival leaves a gap neither side has priced.
- The claim window lasts long enough to include your own quality check after arrival.
Three of these links have their own pages. Where risk and cost pass under a named delivery term is covered in our guide to Incoterms for glass bottle shipments. How the payment clause is worded, and how it holds up once a dispute starts, is covered under drafting the glass bottle purchase contract. The evidence to gather and the order for raising it after a faulty delivery are set out in how to file a warranty claim. Buyers sourcing a stock article instead of a private shape can use our wholesale empty glass bottle collections to set the volume assumptions behind the payment structure.
Stopping or recovering a payment
The options are few, and each is weaker than the one before.
- Before sending. Withhold the remittance. Nothing later is as strong, which is why verification beats every recovery mechanism.
- Sent but not yet credited. Your bank can issue a recall. It works only if the receiving bank has not applied the funds and agrees to cooperate. A recall is a request, not a right.
- Credited. You depend on the receiving bank's fraud procedure or a claim against the beneficiary. Both are slower and costlier than buyers expect.
Under a letter of credit, a complying presentation has to be honoured. Arguing that the bottles are defective does not stop the bank, because its engagement is documentary. Several jurisdictions recognise a narrow fraud exception, yet it is litigated, not routinely applied, and you should assume payment will be made before a court hears you. Build the defence in when drafting: an independent inspection certificate among the documents, inspection ahead of loading, and a check of the presented papers against the credit before the applicant waives a discrepancy.
There is also a lever on the cargo itself. With a documentary credit, the original bills of lading normally stay with the banks until payment. A buyer who has paid nothing may still control the goods after the vessel sails; a buyer who has released the originals has surrendered that control. If a dispute starts after shipment, notify the carrier and the insurer in writing immediately, establish who holds the original documents, then choose between the contract, the claim clause and the bank. Those routes stay open only while the payment chain is still attached to the goods chain.
What to send us for a payment structure review
We can draft a payment structure review for your project from three inputs:
- Order size, which shows whether a documentary credit justifies its administrative cost.
- Stage: a trial run, a first production order on a new mould, or a repeat programme. Each calls for a different structure.
- Risk appetite, meaning how much exposure you will hold in return for a lower unit price.
The review names the method that fits, what the deposit and balance should be tied to, which documents carry the release, and the verification steps to finish before the first remittance.
Frequently asked questions about payment terms and supplier security
Which payment method is least risky on a first order?
Normally a letter of credit, on condition that it demands an independent pre-shipment inspection certificate. The credit deals with a supplier who takes money and never ships. The certificate deals with wrong goods, which a credit alone does not address.
Is it ever acceptable to pay a deposit into a third-party account?
Yes, where a group keeps manufacturing and export in separate entities. Get the link between the contracting party and the account holder in writing first, and verify the account name with the receiving bank directly, not via the email that supplied it. Treat a personal account, or an account name found nowhere in the corporate documents, as a stop condition.
What is a soft clause in a letter of credit?
It is a condition the beneficiary can meet unaided, or one the buyer has no realistic way to meet, which leaves payment at the supplier's discretion. Examples are a quality certificate from the supplier's own representative at the destination port, a document from an authority that will not issue it, and payment tied to the buyer's subjective confirmation that the goods are satisfactory.
How much of the order value should the deposit be?
No single percentage is correct; confirm it against your quotation. New tooling, a first order and a bespoke shape each justify more than a repeat order of an existing stock article. The balance trigger and whether the deposit is refundable on cancellation usually reward negotiation more than the percentage does.
Can a transfer be stopped after it has left the account?
Only briefly, and only if the receiving bank cooperates. Until the funds are credited your bank can send a recall request. After that you are relying on the other bank's fraud procedure or pursuing the beneficiary.
Does a letter of credit protect against poor quality bottles?
No. Banks compare documents with the credit terms and do not look at goods, so compliant documents are paid even when the bottles are defective. Quality protection comes from requiring an independent inspection certificate ahead of loading and using in it the same inspection plan the contract uses.
How should exchange rate exposure be handled?
Name the contract currency and fix the conversion rate in writing on the order date. On an order running several months, open exposure in either direction produces a price change that neither side intended and that is unrelated to the bottles.
What evidence should arrive before the balance is paid?
At least four items: an inspection report dated before sealing, a packing list matching the agreed carton and pallet pattern, photographs of the sealed load, and proof of loading, usually a copy bill of lading. This costs you nothing and hands the supplier a clear, checkable list in place of an open request for reassurance.
