Invoice Payment Terms Explained: Net 30, Net 14 and What They Mean

“Net 30” appears on so many invoices that it’s easy to assume everyone understands it — until you’re the one writing your first invoice and realise you’re not entirely sure what it means, or whether it’s even the right choice for your business.

What “Net” actually means

“Net” simply refers to the full amount due, with the number after it being the number of days the client has to pay from the invoice date. So Net 30 means payment is due 30 days after the invoice was issued, and Net 14 means 14 days. There’s no discount or special condition implied — it’s just a countdown.

Common terms you’ll see

• Due on receipt — payment expected as soon as the client receives the invoice. Common for smaller, one-off jobs.
• Net 7 / Net 14 — a short window, often used by freelancers and small suppliers who need cash flow to stay tight.
• Net 30 — the most common term in UK business-to-business invoicing, and often the default a larger client’s accounts department will expect.
• Net 60 / Net 90 — longer terms, more common with larger enterprise clients or in industries with slower payment cycles, but harder on your own cash flow.

Choosing terms that work for you

Shorter terms get you paid faster but can feel aggressive with larger, slower-moving clients. Longer terms can help win business with bigger companies who have fixed payment cycles, but tie up your cash for longer. A reasonable starting point for most small UK businesses is Net 14 or Net 30, adjusted based on how much trust you’ve built with a particular client — first-time clients might warrant shorter terms, or a deposit up front.

What happens if a client misses the deadline

Under the Late Payment of Commercial Debts (Interest) Act, UK businesses are legally entitled to charge statutory interest and a fixed compensation fee on overdue business-to-business invoices — though whether you choose to enforce that with a particular client is your call. Clear terms stated up front make it much easier to justify following up (or charging interest) if payment doesn’t arrive on time.

Make your terms impossible to miss

Whichever terms you choose, state them explicitly on the invoice itself — “Payment due within 30 days of invoice date” rather than just “Net 30”, which not every client will instantly translate. Our invoice generator has a dedicated Payment Terms field for exactly this, right next to the due date.
