A larger customer offers a steady stream of work on their standard terms, which are sixty days from invoice. The volume is attractive, the name is worth having on a list, and the rate is acceptable. What has actually been offered is a commercial arrangement in which the smaller business funds the larger one for two months at a time, at no interest, and whether that is a good deal depends on several things that are knowable in advance and are almost never asked about before the first job is accepted.
Who Actually Approves the Payment
Terms describe the intention of an accounts department and say nothing about the mechanism, which is where delays actually originate. The useful question is who signs off an invoice, what has to reach them before they can, and how often payments are run. A company paying twice a month on fixed dates behaves very differently from one paying whenever the queue is cleared, and an invoice arriving the day after a run has effectively been given an extra fortnight regardless of what the terms say.
It is also worth asking what causes an invoice to be rejected, because rejection resets everything. A missing purchase order number, an invoice addressed to the site rather than to the accounts address, or a description that does not match the order will frequently bounce a document back without anybody notifying the sender. Establishing the exact format required, before the first invoice, removes the most common reason that sixty day terms turn into ninety day payments.
When the Clock Actually Starts
Sixty days from what is the question that matters, and there are at least three plausible answers in ordinary use. From the invoice date, which is the sender’s preference. From receipt of the invoice, which introduces a gap that depends on how it was sent. Or from the end of the month in which the invoice fell, which quietly adds up to another thirty days and is common enough in commercial terms that it should be assumed rather than hoped against.
Acceptance of the work is the other trigger worth pinning down. Terms that run from acceptance rather than from completion hand the customer control of the start date, and an acceptance that requires a site manager to walk the job can sit for weeks without anyone doing anything wrong. Where that is the arrangement, the practical answer is to agree what acceptance consists of and to seek it in writing on the day the work finishes.
What Carrying the Job Actually Costs
The cost of the arrangement is the money tied up multiplied by how long it is tied up, and it is real even when it is funded from savings rather than borrowed. Material bought at the start of a job and paid for in thirty days, with the invoice settled at ninety, produces a two month gap on the whole material value. Across several concurrent jobs for the same customer, that gap can exceed the annual profit the account generates, which is why volume from a slow payer is more dangerous than a small amount of it.
What Happens If They Pay Late
Every arrangement should have an answer to this before it is needed, since improvising one during a shortfall is how relationships get damaged. A stated interest charge on overdue amounts is normal commercial practice and is worth including even if it is never enforced, because its presence changes the conversation. Free guidance from the Small Business Administration covers the mechanics of arranging a working capital facility for exactly this situation, which is the other half of the answer: a business taking long terms should have a funding line before it needs one rather than after.
Concentration is the risk that sits behind all of this and it builds without any decision being taken. A shop that accepts steady volume from one large customer on long terms will, within a year or two, be carrying a receivable balance that represents a substantial share of everything it is owed, all of it dependent on one payer. That is a comfortable position while the relationship is good and a serious one if the customer disputes an invoice, changes systems, or slows down, and the time to notice it is before the balance gets there.
What the Work Is Worth at Those Terms
All of which points at the last question, which is whether the rate accounts for the terms at all. Long terms are a cost, and a cost that is not priced in is simply absorbed out of margin. Quoting the same figure for a customer paying in fourteen days and one paying in ninety is a decision to earn less from the second, made by default. The alternatives are to price the difference, to ask for a deposit or a progress payment that reduces the exposure, or to accept the terms knowingly because the volume is worth it. Any of those is defensible. Not having noticed is not.
