A Berbice food supplier delivers a large order to a Georgetown hotel. The goods arrive on Monday, but the hotel’s receiving team signs the delivery note on Wednesday. Accounts payable then asks for a corrected invoice and purchase-order number. The supplier expected payment in 30 days; a week has already passed before the invoice is accepted.
The question is not simply whether the customer is reliable. It is when the payment clock starts, what evidence the buyer needs before paying, and how the supplier will fund wages, transport and new stock while it waits. Those details are what credit terms are really about.
A sale is not yet cash
When a supplier offers trade credit, it lets a customer receive goods or services before paying. “Net 30” usually means the full agreed amount is due 30 days after a defined starting event. That event might be the invoice date, delivery, acceptance of the goods or receipt of a valid invoice. The words “net 30” alone do not settle the question. The contract, purchase order and invoice process must make it clear.
Imagine that the Berbice supplier spends G$700,000 to fulfil a G$1 million order. It delivers on 1 September, but the customer accepts the corrected invoice on 8 September. If the agreement gives 30 calendar days from receipt of a valid invoice, the due date would fall on 8 October. If the customer actually pays on 23 October, the supplier has financed its G$700,000 outlay for more than seven weeks. The figures are illustrative, but the difference between a contractual term and actual collection is real.
That is 52 days from delivery to cash, not 30; the seven-day wait for an accepted invoice and the 15 days beyond the due date both matter. The supplier may have paid for ingredients even before delivery, making its full cash exposure longer still. “Net 30” is therefore a contractual description, not a reliable estimate of the number of days for which the supplier must fund the work. A cash forecast should use the date payment is realistically expected, while the contractual date remains the reference for follow-up and dispute resolution.
The sale may still be profitable. Its gross profit before other costs is G$300,000, equivalent to a 30% gross margin on the G$1 million sale. But that profit cannot pay for the next delivery until cash arrives, and any financing cost or unplanned collection work reduces the return. A business that wins several such orders can see revenue climb while its bank balance falls.
If four G$700,000 fulfilment costs are outstanding at once, the supplier has G$2.8 million committed before considering payroll, tax or other customers. The figure does not mean all four invoices will be late; it shows how exposure accumulates when new orders overlap with the old payment cycle. For an investor, the key distinction is between a profitable unit of business and a portfolio of orders the supplier can finance. The latter depends on order frequency, the customer’s actual payment behaviour and the share of sales concentrated in that customer.
Why the start date matters
Credit discussions often focus on whether the customer receives 30, 45 or 60 days. A second question can matter just as much: when does that period begin? A supplier should know who confirms delivery, what constitutes acceptance, which documents must accompany an invoice, where the invoice must be sent and how a dispute is raised.
Consider a construction subcontractor that finishes work on the last day of a month. If its invoice can only be issued after an engineer approves a measurement certificate, a “30-day” term may translate into a much longer wait from the day the work was done. That does not automatically make the arrangement unfair; it does make the cash cycle different from the headline term.
Acceptance can also separate a genuine quality issue from a paperwork delay. If ten pallets arrive and one is disputed, the parties need to know whether the contract permits the undisputed portion to be invoiced and paid while the problem is resolved. Without that clarity, a small disagreement may hold up the entire receipt. Conversely, a supplier that repeatedly sends invoices missing the agreed purchase-order number cannot assume the buyer’s accounts-payable process will correct its mistakes. Clear triggers and evidence make both sides’ obligations easier to test.
The International Finance Corporation’s supply-chain finance programme illustrates how suppliers can turn eligible receivables into earlier cash. Some supply-chain finance arrangements can bring forward payment, but the eligibility, fees and buyer approval still need scrutiny.
Credit is a commercial decision, not a courtesy
A supplier extending credit is taking two risks. The first is timing: payment arrives later than planned. The second is loss: the customer disputes or fails to pay the invoice. A large customer may be attractive, but its size does not remove either risk.
Before agreeing to terms, the supplier should understand the buyer’s purchasing and payment process, check references where appropriate, and decide how much unpaid exposure it can carry. It may set a credit limit, request a deposit, use staged payments or keep a first order on cash terms until a payment history develops. Any decision should reflect the value of the order, the supplier’s margins and the cost of funding it, not just the prospect of winning a prominent account.
Payment timing is also part of the price decision. Suppose the buyer offers to pay the illustrative G$1 million invoice earlier in exchange for a 2% discount. That concession is G$20,000, leaving G$980,000 of revenue and G$280,000 of gross profit against the same G$700,000 fulfilment cost, before other expenses. Whether earlier cash is worth that reduction depends on the days saved, the supplier’s funding cost, the certainty of payment and what else it could do with the released cash. Treating an early-payment discount as “free money” or automatically rejecting it both miss the economic choice.
Credit risk is broader than a customer eventually failing altogether. A disputed invoice, a partial deduction, repeated late payment or a buyer whose orders suddenly dominate the ledger can each change the economics of a sale. Australian government guidance on business payment terms describes the general value of clear terms, credit limits and an overdue-payment process; it is not a statement of Guyana law. The supplier must make its commercial decision using its own contract and cash capacity.
There is also a relationship question. Chasing an invoice becomes harder when nobody can identify who authorised the purchase, who accepted delivery or why a document was rejected. Clear records protect both sides. They turn a vague disagreement into a specific issue that can be corrected.
The number a manager should watch
An ageing report groups unpaid invoices by how long they have remained outstanding. It can show, for example, amounts not yet due, up to 30 days overdue and more than 60 days overdue. The categories are a management choice, but the principle is simple: do not wait until a cash shortage to discover that several customers have slipped past their agreed dates.
Ageing is more useful when paired with a short cash forecast. The forecast asks when payment is likely to arrive, not merely when it is contractually due. If a customer has repeatedly paid two weeks late, treating its next invoice as certain to arrive on the due date would conceal the risk. Our working-capital Explainer shows why this gap matters, and the 13-week cash-flow Guide turns that information into a weekly decision tool.
Credit terms also need to be revisited. A customer that once paid promptly may begin disputing invoices or exceeding its agreed limit. A fast-growing supplier may find that a term it could support at G$1 million of sales becomes difficult at G$10 million. Terms are part of managing a relationship over time, not a one-off formality.
The buyer has a stake in making the terms workable as well. A hotel that consistently delays approval or pushes payment beyond the agreed date may force a small supplier to raise prices, reduce deliveries or seek expensive finance. Supplier credit can support a relationship when the buyer’s process is predictable; it is not an unlimited source of finance. For both parties, the defensible arrangement is one in which the due-date event, documentation, dispute route and actual payment performance are visible rather than left to assumptions.
Back to the supplier
The Berbice supplier’s hotel order may be worth taking. The decisive question is whether it knows the true payment path and can finance that path without jeopardising its next order. A well-written “net 30” agreement will define the clock, the documents and the response when something goes wrong. A practical credit policy will determine whether the business can afford to offer it.
The companion Invest Guyana Guide, How to Create a Customer Credit Policy and Collection Process, translates these questions into a usable approval and follow-up sequence. The Explainer’s point is more fundamental: payment terms are not a small line on an invoice. They shape the cash and risk behind every sale.
