Three Practical Limits of Payment Terms and Acceptance Bills in Packaging Procurement: Net Payment Days / Bank Acceptance Discounting Costs / Credit Limits and Consequences of Overdue Payments — The First Three Numbers a Printer Should Ask a Customer Before Accepting an Order
💡 💡 At a Glance
This article identifies three practical boundaries in packaging procurement payment terms. First, net payment terms consist of three parameters: the starting date (shipment, invoice, receipt confirmation, or inspection confirmation, which may differ by 10–30 days during the production cycle), the number of days (the incomplete starting month can shift actual cash days, and quarterly settlement can create year-end payment peaks), and whether early payment is allowed, including any early-payment discount. Second, bill-discounting costs must be included in quotations. Bank acceptance bills are based on bank credit, while commercial acceptance bills are based on the customer’s own credit and generally have different discount rates and ease of discounting. Discounting cost ≈ bill face value × annualized discount rate × remaining days ÷ 365 + fees. Discounting a six-month commercial acceptance bill for three months may consume about 2% of face value, equal to one-seventh of the gross margin on a 15%-margin order. A three-month bill can therefore cost roughly one-third of a six-month bill rather than one-half. The proportion of bills should be written into the quotation, such as “Net 60 days, with commercial acceptance not exceeding 30%.” VAT timing and 20%–30% advance or progress payments are also easily overlooked. Third, exhausting a credit limit does not merely delay payment; it may prevent the printer from accepting new orders. The limit’s calculation basis, such as whether it includes tax and bill balances, should be confirmed. Reconciliation in mid-month and one-month advance warning are recommended. Overdue-payment procedures should establish in advance when to suspend new orders, hold completed unshipped goods, and begin legal action. Before accepting an order, printers should ask three questions: the starting date; the bill type, tenor, and proportion; and the customer’s credit limit and its calculation basis.
In August 2026, a customer producing mooncakes approached us for a batch of 80,000 gift boxes.
We negotiated a unit price that met our expectations, and the order volume was substantial, so we were pleased. When we discussed the payment method, the customer said, “Net 60 days.”
We asked, “For net 60 days, does the period begin on the shipment date or the invoice date?”
The customer said, “Does it make a difference?”
We replied, “It makes a big difference. We need 25 days for material preparation and 15 days for production. Adding approximately 10 days for your inspection and confirmation means that by the time the goods ship, we have already spent 50 days on paper and labor. If the period starts from shipment, we cover only 10 days; if it starts from the invoice date, we cover 60 days. We also cannot issue the invoice until your inspection is confirmed.”
The customer thought for a moment and said, “Then let us calculate from the invoice date.”
We said, “There is one more question: Will the 60-day payment be made in cash or through an acceptance bill?”
The customer said, “…Commercial acceptance, six months.”
We then had to recalculate the entire order.
In packaging procurement, the most expensive element is often not the unit price but the payment terms. This article examines three practical boundaries: how payment periods are calculated, how bill-discounting costs are calculated, and what happens when a credit limit is exhausted or a payment becomes overdue. The three numbers a printer should ask first when accepting an order appear in the final section.
First Boundary: Payment Terms Are Not One Number but Three Parameters
The phrase “net 60 days” contains three parameters that must be separated: the starting date, the number of days, and whether early payment is permitted. Omitting any one of them can shift the effective payment period by anywhere from one week to one month.
The first parameter: the starting date. In practice, there are at least four possibilities: the printer’s shipment date, the invoice date, the customer’s receipt-confirmation date, or the date on which the customer confirms that the goods have passed inspection. During the printer’s production cycle, these dates can differ by 10 to 30 days.
Why such a large difference? Because a printer’s material preparation and processing work occur in advance. Paper must be ordered early, ink must be mixed early, and foiling plates must be made early. Once a print job is scheduled, it occupies production capacity. These costs have already been incurred before the customer confirms receipt of the goods.
The customer said, “We can calculate from shipment. Our inspection will be quick.”
We replied, “Your inspection may be quick, but our cash flow does not run at your pace. If the goods fail inspection and require rework, that period also falls within the payment term. If the term is calculated from the invoice date, we bear no cost during the rework period; if it is calculated from shipment, we bear that cost ourselves.”
The second parameter: the number of days itself. Here there is an easily overlooked calculation difference: “60 days” calculated from the invoice date and “60 days” calculated from the shipment date are not the same number in a net-payment arrangement, because the month in which the period begins is usually incomplete. Customers billed at month-end and those invoiced in the middle of the month may receive several more days of actual cash. The difference is not large, but over a long-term relationship involving small orders, it becomes material over a full year.
There are also two variants: quarterly settlement and annual settlement. Customers with quarterly settlement often make a concentrated wave of payments at year-end, placing several times the usual cash-flow pressure on the printer. If a customer places four large orders a year and settles each one quarterly, the printer must plan its funding for the worst quarter.
The third parameter: whether early payment is permitted, and whether it carries a cost. “Early payment is permitted” must be converted into a contractual term: Is a discount offered for early payment? If so, how is the discount calculated? Some customers offer early-payment discounts, such as 2% for payment within 10 days. This effectively shares part of the financing cost with the customer while giving the printer some compensation. Some customers offer no discount, in which case early payment is a pure loss for the printer because the money could otherwise earn interest or be used on another order.
Second Boundary: Bill-Discounting Costs Must Be Included in the Quote
“Net 60 days” combined with “six-month commercial acceptance bill” is very different from “30% cash in advance, with the balance payable net 60 days.”
First, the distinction between the two types of bills is fundamental and must be understood clearly.
Bank acceptance bills are accepted by a bank, which assumes the obligation to pay at maturity. Their credit foundation is the bank, and the customer’s actual credit risk depends on whether the bank’s issuance limit has been used. Commercial acceptance bills are accepted by the company itself. Their credit foundation is the customer, and if they are not paid at maturity, the printer can only seek payment directly from the customer.
The customer said, “A commercial acceptance bill is the same. My company is very large.”
We replied, “It may be the same for you, but it is not the same for us. No matter how large your company is, when a commercial acceptance bill is not paid at maturity, will the money come from a bank or from you? The difference is that bank acceptance bills can be discounted in the market. Commercial acceptance bills can also be discounted, but their discount rates and discountability are not in the same category.”
Now comes the core calculation. Discounting converts a bill into cash before maturity: on day 30, you take a 180-day bill to a bank for discounting, and the bank pays you after deducting interest for the period from the discount date to maturity, together with any fees. In simple terms:
Discounting cost ≈ bill face value × annualized discount rate × remaining days ÷ 365 + fees
How should this figure enter the quote? The customer’s true cost equals the unit price plus this discounting cost. Consider a real example at the level we have calculated: for a six-month commercial acceptance bill, if the annualized discounting cost is estimated at 4% to 6%, discounting it for three months can consume approximately 2% of its face value. If the order’s gross margin is 15%, that 2% represents one-seventh of the gross margin.
The difference in tenor is even more important: the discounting costs of a three-month bill and a six-month bill are not twice versus one; they are three times versus one, because the cost is directly proportional to the remaining days. Customers therefore have to make a choice: accept a slightly lower price with a shorter payment period, or accept a slightly higher price in exchange for a proportion of commercial acceptance bills that can be discounted.
The customer asked, “Can’t you give us a longer payment term?”
We replied, “We can discuss it, but you need to understand what an additional 30 days means to us. At our current material-preparation and production pace, every additional 30 days increases the amount of money tied up in this batch. We can discuss it, but it is part of the price.”
One practical recommendation is: include the proportion of bills in the quotation. For example: “Net 60 days, of which commercial acceptance bills may not exceed 30%; the balance by bank transfer.” This clause is not intended to make things difficult for the customer. It enables the customer to balance the terms internally. Many procurement managers themselves do not know what proportion of commercial acceptance bills their company can issue. Once they ask, they often discover that finance has approved only a low proportion, creating an incentive to change the payment method.
Two other cash-flow-related items are often overlooked: the tax rate and timing of invoicing—the time gap between input VAT and output VAT represents real tied-up capital—and whether there are advance payments and progress payments. Many customers are willing to provide a 20% to 30% advance payment; the procurement process simply has no provision for it.
Third Boundary: Exhausting the Credit Limit Does Not Mean Paying a Few Days Late
This point is most likely to be overlooked by both parties because it is completely invisible during ordinary business.
A customer-provided credit limit is subject to conditions: it reflects the customer’s ability to pay and its internal approval process. For example, if a customer grants the printer a credit limit of RMB 500,000, once the value of outstanding orders reaches RMB 500,000, new orders must either wait for existing orders to be settled or require the customer to apply for an increased limit internally. Increasing the limit requires a process, and the process takes time.
What does this mean in practice? It means that when the limit is exhausted, the printer may face not merely “a few days of delayed payment,” but an inability to accept any more work for the rest of the month. An even worse scenario is that the customer has placed an order, the printer has begun material preparation, and the customer then says that the additional limit is awaiting approval.
The customer said, “That won’t happen. We have given you plenty of credit.”
We replied, “That is precisely why we need to review it in advance. It matters how the limit is calculated: whether it is based on the unsettled amount or the tax-inclusive amount, and whether bill balances are included. These details can make a substantial difference. Our practice is to reconcile accounts in the middle of each month, compare the unsettled value of work in hand with the customer’s credit limit, and issue a warning one month in advance rather than discovering on the shipment date that we cannot accept the order.”
The boundaries of overdue-payment remedies also need to be clear. When a customer fails to pay on time, a printer can usually take three actions: stop accepting new orders—the most effective measure, but also the most damaging to the relationship; stop shipping goods still held at the factory; or take legal action, which is lengthy and damages relationships and is therefore normally the last resort. The first two measures are the genuinely effective ones, but they must be agreed in the contract or established as part of the long-term working relationship in advance. Otherwise, enforcing them in a crisis will be difficult.
The customer said, “Will it really come to that?”
We replied, “Most orders will not. But a printer must be prepared, because its true cost is money. A printer owner calculates cash every day, not merely the figures on the income statement.”
The First Three Numbers to Ask When Accepting an Order
At the negotiating table, these three numbers are more important than the unit price.
The first number: the starting date. Is it calculated from shipment, from the invoice date, or from the customer’s inspection confirmation? During the printer’s production cycle, this can make a difference of 10 to 30 days.
The second number: the type and tenor of the acceptance bill. Cash, bank acceptance, or commercial acceptance? Is the tenor three months or six months? What proportion will be paid by bill? This determines whether the discounting cost can be calculated.
The third number: the credit limit granted by the customer and the basis on which it is calculated. At what level of outstanding balance will the printer be unable to accept new orders?
Once these three numbers are clear, you will know the order’s true gross margin and the true significance of the customer to your business.
One Sentence for Customers
On payment terms, the most important thing we want to tell customers is: “Put the starting date in the contract, rather than merely the number of net payment days.”
The customer said, “Writing down the starting date is so troublesome.”
We replied, “It is not troublesome. But if we do not write it down, at some point we will both feel we have been treated unfairly. You will think the period should begin from the invoice date, while we will think it should begin from shipment. Discovering this after the order has been executed is far more troublesome than writing one sentence.”

FAQ
Does it make a significant difference whether the payment term begins on the shipment date or the invoice date?
It can make a difference of 10 to 30 days during a printer’s production cycle. With 25 days for material preparation, 15 days for production, and 10 days for customer inspection, paper and labor costs have already been incurred for 50 days by shipment. If the term begins from the invoice date, the printer covers the full payment period; if it begins from shipment, the printer covers only the remaining days. However, the true loss often lies not in this period itself but in the rework period. If inspection fails and rework is required, the printer bears no cost for that period when calculating from shipment but bears the entire cost when calculating from the invoice date. For this reason, this point must be put into writing in the contract, with an explicit statement that an overdue inspection is deemed to constitute confirmation.
How should a printer price the difference between commercial acceptance bills and bank acceptance bills?
The difference appears in two areas. First, the credit-risk party differs: with a bank acceptance bill, the bank is responsible if payment is not made at maturity; with a commercial acceptance bill, the printer can only pursue the customer itself. Second, market acceptance differs, with discount rates and discountability falling into different categories. The most direct practical step is to include the bill proportion in the quotation, for example: “Net 60 days, of which commercial acceptance bills may not exceed 30%; the balance by bank transfer.” The purpose is not to make things difficult for the customer but to let the customer balance the terms internally. Many procurement managers do not know how much commercial acceptance their company can issue and may discover that finance has approved only a small proportion, creating an incentive to change the payment method. Discounting costs can be estimated using “bill face value × annualized discount rate × remaining days ÷ 365 + fees” and stated in the quotation notes.
Why should a 30-day payment term not be granted free of charge?
Because a payment term is a financing cost, and it is rigid for a printer. Spending on paper, labor, ink mixing, and foiling plates occurs before the customer confirms receipt. Every additional 30 days increases the capital tied up in the order. This is not merely a reduction in accounting profit; it is an occupation of actual cash that may not even be visible on the income statement. The appropriate approach is therefore to price the payment term. If the customer wants an additional 30 days, the printer may agree, but there should be a price difference. This makes it clear what both sides are exchanging and is healthier than an ambiguous “just get started” arrangement.
What happens when a customer exhausts the credit limit granted to the printer?
The consequence is not a few days of delayed payment but the possible inability to accept new orders. The limit reflects the customer’s ability to pay and its internal approval process. When the value of outstanding orders reaches the limit, a new order must either wait for existing orders to be settled or require an internal increase in the limit, which takes time. If the printer discovers this only after beginning material preparation, it is left with no alternative. The correct approach is proactive credit-limit management: reconcile accounts in the middle of each month, compare the outstanding balance with the customer’s credit limit, and issue a warning one month in advance. During negotiations, confirm the basis of calculation, including whether it is based on the unsettled amount or the tax-inclusive amount and whether bill balances are included, because these details can make a substantial difference.
Can a printer really withhold shipment if the customer fails to pay on time?
Only if this has been agreed in advance. Without a contractual provision or an established understanding, enforcement will be awkward: the goods have already been printed and the paper has already been cut, and the customer may say, “Send me the goods first, and we will settle everything next week.” The three rules should therefore be established at the beginning of the relationship: the conditions under which new orders may be stopped, the conditions under which completed but unshipped goods may be held, and the number of days of delinquency after which legal proceedings begin. Most orders will not reach the third stage, but a printer must have contingency plans for the first two because printers calculate cash every day rather than merely tracking figures on the income statement. Suspending new orders is often the most effective measure but also the most damaging to the relationship, so it should be communicated in advance rather than presented as a sudden reversal.
