Invoice Payment Terms Explained: Net 30, Net 15 & More

Payment terms are the rule that turns your invoice date into a due date. Net 30 is not a suggestion — it is an instruction to pay the full amount within 30 days of the invoice date. An invoice dated 1 August on Net 30 terms is due 31 August.

Terms do a second job: they set expectations before there is a problem. A client who agreed to Net 14 has no grounds to sit on your invoice for two months, while without stated terms, payment tends to happen whenever the client decides — though in some jurisdictions a default payment period applies whether you stated one or not.

Due on receipt means payment is expected as soon as the client receives the invoice — in practice, within a day or two. It suits small one-off jobs and first-time clients, but many companies physically cannot pay same-day because every invoice goes through an approval and payment-run cycle.

Net 7, Net 14, Net 15, Net 30, and Net 60 all count calendar days from the invoice date. Net 7 through Net 15 are common for freelancers and small jobs, Net 30 is the default in much of business-to-business trade, and Net 60 mostly appears when large companies impose their standard terms on suppliers.

EOM terms count from the end of the month instead of the invoice date. Net 30 EOM on an invoice dated 12 July means 30 days after 31 July — due 30 August, not 11 August. Some businesses also use plain EOM to mean due by the last day of the current month, so if a client proposes EOM terms, confirm which reading they intend.

2/10 Net 30 offers a trade: the client can deduct 2% if they pay within 10 days, otherwise the full amount is due in 30. On a $3,000 invoice, that means $2,940 if paid by day 10, or the full $3,000 by day 30.

Do the math before offering it. Giving up 2% to get paid 20 days sooner works out to roughly 37% on an annualized basis — expensive money if you do not genuinely need the acceleration. It makes sense when cash flow is tight, or with a client who reliably takes the discount and genuinely pays early.

Two cautions. Some clients take the discount and still pay on day 30, so decide in advance whether you will chase the difference. And where you charge VAT, GST, or sales tax, a settlement discount can affect how the tax is calculated in some systems — check your local rules before building discounts into your invoices.

Start from your cash flow, not from convention. If you invoice monthly and your own bills are due monthly, Net 60 means floating two months of expenses. For solo freelancers and small businesses, Net 7 or Net 14 is entirely reasonable — shorter terms are normal at smaller scale, and most clients will not blink.

Large clients are a different negotiation. Their accounts payable systems run on fixed cycles, and Net 30, 45, or 60 may be company policy you cannot change from the invoice line. What you can do is confirm their payment-run dates, submit invoices before the cutoff, put any required purchase order number on the invoice, and price the waiting into your rate.

In some regions, laws set default payment periods or limit how long one business can take to pay another, which can strengthen your hand in negotiation — worth checking where you are registered. Whatever you agree, put it in the contract or engagement email before the first invoice; terms that first appear on the invoice itself are much weaker.

State terms twice: once as the shorthand and once as an explicit date. A payment terms line reading Net 30 plus a due date field reading 31 August 2026 leaves no room for interpretation and no math for the client's bookkeeper. The terms line usually sits near the totals or in the notes area, next to your payment details.

The terms and the due date field must agree — they are two views of the same fact. If the invoice says Net 14 but the printed due date is 30 days out, the client will pay to the later date every time. So compute the date from the terms yourself and enter it; never leave the due date blank and hope the shorthand carries it.

Keep terms consistent from invoice to invoice for the same client. If one invoice says Net 14 and the next says Net 30 with no explanation, the client's accounts team will default to the longer one — or query the invoice, which delays payment further still.

Typical wording is short: overdue balances accrue a late fee of 1.5% per month, or late payments are subject to interest from the due date at a stated rate. Put the same clause in your contract, not just on the invoice — a fee the client never agreed to is hard to collect in most places. The main exception is the statutory late-payment interest covered below.

Whether a late fee is enforceable depends on where you are and what was agreed. Some jurisdictions cap the interest you can charge, some grant statutory interest on late business-to-business payments automatically, and some will not enforce a charge that looks like a penalty rather than compensation. Check the rules where you are registered before you rely on the number.

In practice, a late fee's main job is deterrence. Many freelancers never actually collect one — they waive it once payment lands — but the clause signals that you track due dates, and it gives you something concrete to point to when you chase. A polite reminder that the invoice is 15 days overdue and the contract's late fee clause now applies moves money faster than the fee itself ever will.
