Net 30 vs Net 60: Practical Invoice Due Date Guide

Net 30 generally gives the customer 30 days after an agreed starting event, while Net 60 generally gives 60 days. The starting event may be the invoice date, receipt of a valid invoice, acceptance, delivery, or another contract event.

• Net 30: shorter collection cycle for the supplier and less payment time for the customer.
• Net 60: longer payment window for the customer and a longer receivables period for the supplier.
• Neither label tells you by itself whether to count calendar days or business days.

If the agreement only says Net 30, many systems count 30 calendar days, but the contract or customer policy controls. If the parties mean business days, say so and identify the weekend and holiday calendar. An EOM term first anchors the calculation to the end of the invoice month; EOM + 15 then adds 15 days from that anchor.

Also state what happens when the calculated date falls on a weekend or holiday: move to the next business day, move to the previous business day, or keep the original date.

For an invoice dated June 8, 2026, a simple calendar-day calculation gives July 8 for Net 30 and August 7 for Net 60. If the written term instead uses business days, or starts after acceptance rather than the invoice date, the due dates will be later.

For EOM + 15, the same June invoice first anchors to June 30 and then adds 15 days, producing July 15 before any weekend or holiday adjustment.

A longer term can help a customer align payment with its approval and cash cycle, but it also extends the supplier's receivables period. A shorter term can improve collection timing but may not fit a large customer's procurement process.

This is a workflow comparison, not financial or legal advice. Check local law, customer onboarding rules, purchase orders, and the signed contract before changing payment terms.

Replace an ambiguous label with a complete rule that both accounting systems can reproduce.

• Name the starting event: invoice date, receipt, acceptance, delivery, or month end.
• Say calendar days or business days.
• Identify the governing country, weekend, and holiday calendar when business days apply.
• State the weekend and holiday adjustment rule.
• Print the resulting due date on the invoice and confirm it against the contract.
