Frequently Asked Questions
How do I calculate a Net 30 due date?
Add 30 calendar days to your invoice date. An invoice dated May 1 under Net 30 is due May 31. Use the calculator above to get the exact date for any invoice.
Does Net 30 include weekends?
Yes — Net 30 counts calendar days, not business days. If the 30th day lands on a Saturday or Sunday, most clients will pay on the preceding Friday or the following Monday.
Why does the calculator show an "estimated actual payment" date?
Most medium and large companies run AP (Accounts Payable) payment batches twice a month — typically on the 1st and 15th. If your due date falls between payment runs, you'll wait until the next scheduled run. The estimate shows when you're likely to receive the money in practice, not just on paper.
What should I write on my invoice?
Write both the payment terms and the explicit due date: "Net 30 — Due May 31." An explicit date is much harder for AP departments to overlook than a relative term, and it gives you a specific date to reference if you need to follow up on late payment.
Can I negotiate my payment terms?
Yes — but the time to negotiate is before signing the contract or purchase order, not when you send the invoice. Once a PO is issued with Net 60 terms, AP will follow the PO regardless of what your invoice says.
