Invoice payment terms explained: Net 30, Net 15 and what actually gets you paid

July 20, 2026 · 8 min read

Net 30, 2/10 Net 30, due on receipt — payment terms look like jargon but they are the strongest lever you have over when money arrives. Here is what each one means and which to use for your business.

Payment terms are the least glamorous part of an invoice and the part with the most direct effect on your bank balance. They decide when the money is due, what happens when it is late, and how much room a slow-paying client has to stretch you. Most small businesses inherit their terms from whatever template they first downloaded and never revisit them.

That is worth fixing, because the difference between Net 30 and Net 14 is two weeks of your cash — repeated across every invoice, every month, for as long as you are in business.

What the standard terms actually mean

Due on receipt

Payment is expected immediately. In practice this means within a day or two, and it is best suited to one-off jobs, new clients with no payment history, and consumer work where the client is standing in front of you. It is the strongest term you can set and the most likely to be quietly ignored by larger organisations with a payment run.

Net 7, Net 14, Net 15

Payment is due that many days after the invoice date. Net 14 is the sweet spot for most small service businesses: long enough that no reasonable client objects, short enough that a single late payer does not put you in overdraft. Net 15 exists mainly because it aligns neatly with twice-monthly payment runs.

Net 30

The default across commercial work, and the term most likely to be imposed on you rather than chosen. Thirty days after the invoice date. It is standard because it suits the buyer, not the seller. If you work mainly with businesses you will often have to live with it — but you should not offer it by default to clients who have not asked.

Net 60 and beyond

Common with large corporates and public sector clients. If you take on this kind of work, price the delay in. Two months of financing someone else's operations is a real cost and should be reflected in the rate.

2/10 Net 30

A discount for early payment: take 2% off if you pay within 10 days, otherwise the full amount is due in 30. It looks generous, and it can work — but do the arithmetic before you offer it. Giving up 2% to be paid 20 days sooner is an annualised cost of roughly 37%. That is only worth it if your cash position genuinely requires it.

50/50 and milestone terms

A deposit up front and the balance on completion, or staged payments tied to milestones. For any job large enough that a non-payment would hurt, this is the safest structure available to a small business. A client who will not pay a deposit is telling you something useful before you have spent anything.

The term matters less than the date on the page

Here is the part most guides skip. Clients do not think in terms. They think in dates. An invoice that says Net 14 requires the reader to find the invoice date, add fourteen days, and write it in a calendar. Most people will not do that, and the invoice sits in a pile until someone chases it.

An invoice that says Due Friday 19 September 2026 needs no interpretation. Put the actual date in large type near the total, not buried in a terms paragraph at the bottom. This single change is worth more than any adjustment to the term itself.

• State the due date as a real calendar date, not only as a number of days.
• Put it near the amount due, where the eye already goes.
• Repeat it in the email or message body, not just inside the PDF.
• Say what happens after that date — even if the answer is a polite reminder.

Late payment terms that actually hold

A late fee written on an invoice is only enforceable if the client agreed to it before the work started. Adding 5% to an overdue invoice that never mentioned a late fee is a conversation you will lose, and it damages the relationship on the way.

The sequence that works is: state your terms in the quote, repeat them on the invoice, and only then apply them. A typical structure is a fixed administrative fee or a percentage per month on the outstanding balance, capped at something reasonable. Check what is permitted where you operate — many jurisdictions set a statutory ceiling, and several give small businesses a statutory right to interest and recovery costs on late commercial payments whether or not the invoice mentions it.

In practice, most of the value of a late fee is deterrence rather than collection. Clients pay invoices that have consequences before they pay invoices that do not.

Choosing the right terms for your business

There is no universally correct answer, but there are sensible defaults.

• New client, small job, consumer work: due on receipt, or payment on completion.
• Repeat client, established relationship: Net 14.
• Commercial client with a procurement process: Net 30, and expect it to be enforced from their side.
• Any job over roughly a fortnight of your time: deposit up front, balance on completion.
• Large corporate or public sector: Net 30 to Net 60, priced accordingly.

The mistake to avoid is offering your longest terms to everyone because one client demanded them. Terms are per-client, not per-business, and there is no obligation to be consistent across clients who present very different risk.

The follow-up schedule that does most of the work

Most late payments are not refusals. They are invoices that got lost in an inbox, or that arrived after a payment run and quietly waited for the next one. A predictable follow-up rhythm resolves the large majority of them without any friction.

• Three days before the due date: a short, friendly note confirming the invoice is due and asking whether everything is in order.
• The day after the due date: a brief message noting the date has passed, with the invoice attached again.
• Seven days late: a firmer note referencing the agreed terms and any late fee.
• Fourteen days late: a phone call. Not an email — a call.

Attaching the invoice again every single time removes the most common excuse. Calling at day fourteen resolves more disputes than four more emails ever will.

Make paying the easy option

Every extra step between the client's intention to pay and the money leaving their account is a chance for the invoice to go back in the pile. Your payment details belong on the invoice itself, in full, not in a separate email sent three weeks earlier. The invoice number belongs in the file name and the subject line so it can be forwarded to whoever actually processes payments without any explanation.

It is worth remembering that the person who commissioned the work is often not the person who pays for it. Your invoice will be forwarded. Write it so it makes complete sense to someone who has never met you and knows nothing about the job.

Getting the terms onto the document

None of this helps if the terms live in your head and never reach the page. The practical answer is to set them once and have every document inherit them. Inqo carries your terms and due date from the quote through to the invoice, assigns a sequential invoice number the moment you finalise, and puts the due date where the client will actually see it — so the follow-up conversation, when it happens at all, is short.
