Net 30 payment terms mean the full invoice amount is due 30 days from the invoice date — not 30 business days, and not 30 days from when the client got round to opening it. That distinction is where most late-payment disputes actually start.
Net 30 means the full invoice amount is due 30 calendar days after the invoice date. Net refers to the total with no deductions, and 30 is the number of days. It is not 30 business days.
From the invoice date by default. If you want the clock to start on delivery or on receipt of the invoice, you have to say so explicitly on the invoice and in your terms — otherwise the invoice date governs.
Only when the client requires it or the relationship justifies it. Net 30 means financing your client for a month; Net 7 or Net 14 is normal for solo and small operators and materially improves cash flow.
A 2% discount if the invoice is paid within 10 days, otherwise the full amount is due at 30 days. You are paying roughly 2% to receive the money 20 days sooner.
