Your packaging supplier has delivered several runs of printed cartons, and your team has paid each agreed instalment. For the next run, you want some of the balance to fall due after shipment. A smaller deposit would help during production, but paying everything before the cartons leave still ties up the purchase money in transit. You are asking the seller to extend credit, not simply change a percentage.

The purchasing situations and proposed terms below are fictional illustrations, not customer transactions or standard market terms. This article is general information, not legal, tax or investment advice. A repeat-order history does not guarantee supplier credit or performance.

Be clear about the credit you want

The International Trade Administration's trade finance guide describes an open-account sale as one where goods are shipped before payment is due. That is the distinction to settle with your supplier: which amount remains unpaid after shipment, and for how long? Moving the balance to a point before dispatch is not after-shipment credit.

A historical buyer question dated October 3, 2026 asked how suppliers had agreed to better terms and whether order history helped. It is a self-reported forum question, not evidence of how often sellers grant credit or what terms you can obtain.

If your immediate need is a smaller advance rather than later settlement, use the T/T payment-split guide. Do not call a reduced deposit “net terms” while leaving the whole invoice payable before shipment.

Give the supplier a reason to consider a pilot

Bring a short purchase history to the conversation: completed orders, agreed and actual payment dates, amounts credited, and how your teams resolved changes or defects. The useful evidence is not just that you placed orders. It is that the supplier's finance team can reconcile them without chasing unexplained balances.

For the carton buyer, a sensible opening is a familiar repeat specification and a limited deferred balance on one shipment. A larger custom run with new tooling introduces different questions. Describe the pilot's scope, review point and proposed return to the previous terms if either side decides not to continue.

The supplier may decline or request information about your business's ability to pay. Respond through an agreed document channel and share only material relevant to the assessment. A discount, longer credit period or expanded limit needs separate agreement; none follows automatically from completing the pilot.

Cap the total outstanding exposure

A limit per invoice can become misleading when orders overlap. The cartons from Order A may be on the water while Order B is ready to ship. Both deferred balances would be owed to the same seller, even if purchasing manages them in separate folders.

Propose an aggregate outstanding-credit cap in an agreed currency. Define what counts toward it: all unpaid credit balances across orders, including overdue and disputed sums unless the supplier has formally agreed otherwise. Also decide whether the supplier reserves capacity under that cap for accepted orders awaiting shipment.

Before another shipment uses the credit arrangement, compare the existing debt plus its proposed deferred balance with the cap. If the combined exposure would exceed it, agree a payment, smaller shipment or revised schedule first. A pending transfer should not free capacity merely because your buyer has a screenshot marked “sent”.

Write a clock that both finance teams can use

“Net after shipping” leaves too much room for disagreement. For this fictional pilot, the parties could choose 20 calendar days after the on-board shipment date shown on the carrier-issued bill of lading. Specify that the event date is day zero and counting starts the following calendar day. This is an example to negotiate, not a recommended standard.

The written terms should identify:

  • The deferred amount, invoice currency and orders covered.
  • The exact triggering event and document that establishes its date.
  • The invoice, packing list and shipment evidence to be supplied, and when.
  • The calendar-day count, actual due date and treatment of weekends or holidays.
  • Whether payment must be received by the due date or merely initiated.

Document delivery and the shipment event are different dates. Agree whether missing or corrected documents change the deadline rather than assuming they do. For partial shipments, identify which balance and due date belong to each shipment. Your accountant should be able to calculate the deadline without interpreting a salesperson's “shipped” message.

Decide what happens before the next order

Settle the overdue-debt rule while everyone is still discussing the pilot calmly. Does an overdue balance pause new credit shipments, production or acceptance of another order? Who can approve an exception? Put any late charges and notice requirements in the agreement and have the terms reviewed where needed.

A quality dispute also needs a defined process. Record the disputed amount, evidence, response timetable and treatment of the undisputed balance. Do not assume a complaint suspends the entire debt or removes it from the exposure cap. Any revised due date or credit note needs the supplier's written agreement.

Use the partial-payment guide to track invoice credit and the second-invoice guide when a new demand does not match that history.

Use pay an invoice to ask A2vanta about a proposed settlement before funding. The supplier grants the credit; payment handling does not grant it, extend its due date or guarantee the goods.
