Net 15 vs Net 30
Net 15 and Net 30 are invoice payment terms. Net 15 usually means payment is due 15 calendar days after the invoice date, while Net 30 usually means 30 calendar days after the invoice date.
Due date timing
The difference is simple but important: Net 15 gives the customer roughly half the time of Net 30. If an invoice is dated June 4, a Net 15 calendar due date lands much sooner than a Net 30 due date. That shorter window can improve cash flow, but it may be harder for some customers to process.
Both terms are commonly treated as calendar-day terms unless the invoice or agreement says business days. If a due date falls on a weekend or holiday, many teams use the next business day for reminders, but the invoice wording should control the actual term.
Cash flow and customer expectations
Net 15 can be useful for small projects, recurring services, deposits, or clients that expect faster payment. Net 30 is common for larger organizations and customers with formal accounts payable cycles. The right term often depends on bargaining power, customer process, and how quickly the seller needs cash.
Operational follow-up
For either term, track the calendar due date separately from internal follow-up dates. A follow-up date might move to the next business day after a weekend or federal holiday, while the invoice due date remains tied to the written term.
