What “Net 30” means
Net 30 means the full amount of the invoice is due 30 days after the invoice date. “Net” refers to the total after any agreed discounts. Net 7, Net 15, Net 45, Net 60 and Net 90 work the same way. Unless your contract says otherwise, the days are calendar days, and the count starts the day after the invoice date.
Early payment discounts
“2/10 Net 30” means the client may take 2% off if they pay within 10 days; otherwise the full amount is due in 30 days. It costs you 2% but can speed up cash flow considerably.
Write the date, not just the terms
Clients pay on time more often when the invoice shows the actual due date (“Due 26 November 2026”) as well as the terms. The invoice generator fills in the due date from the terms you choose.
Which terms should you use?
- Due on receipt or Net 7: consumers and small jobs.
- Net 15 to Net 30: most freelancers and small businesses.
- Net 45 to Net 90: large companies often insist on these; price them in or ask for a deposit.
How the count works
Day 1 is the day after the invoice date. An invoice dated 1 October on Net 30 is due on 31 October; one dated 15 January is due on 14 February. With business days, weekends are skipped, and the calculator also moves a calendar due date that falls on a weekend to the next Monday, which is how many accounts teams treat it. Public holidays aren’t counted separately.
