Does net 30 mean calendar days or business days?

Calendar days. Net 30 is 30 calendar days from the invoice date, weekends and holidays included. If the 30th day lands on a weekend, convention is that payment is due the next business day.

When does the clock start on net terms?

On the invoice date — the date printed on the invoice — not the date the client receives or approves it. To avoid disputes, send invoices the day you date them.

What terms should freelancers use?

Net 14 or due on receipt is reasonable for most freelance work. Reserve net 30 for larger clients whose accounts-payable process genuinely needs it, and consider late-payment interest after the due date — our Late Fee Calculator works out the amount.

What net terms actually mean

"Net 30" means full payment is due 30 calendar days after the invoice date — not 30 days after the client first opens it, and not 30 business days. The clock starts the day you issue. That distinction matters: a client who sits on an invoice for a week hasn't bought themselves an extension, and your reminder schedule shouldn't wait for them.

Due dates that land on a weekend or holiday quietly add days, because accounts-payable teams don't run payments on Saturday. Rolling the due date to the next business day (the default here) reflects when money can actually move — but state the rule in your contract so there's no debate about whether Monday counts as late.

Why shorter terms get you paid faster

Freelancers inherit net 30 from corporate purchasing departments, but nothing requires it. Net 14 — or due on receipt for small projects — is normal for independent work, and most clients simply pay to whatever terms the invoice states. Longer terms mainly benefit the client's cash flow at the expense of yours.

Whatever terms you choose, pair them with a reminder ladder: a friendly nudge a few days before the due date, a note on the day, and firm follow-ups at one and two weeks overdue. Most late payments aren't malice — they're invoices that fell off someone's list, and a timely reminder is all it takes.
