Net 15 payment terms mean the invoice is due 15 calendar days after the invoice date — half the credit of Net 30, and for most small businesses the better default. Here is when it is appropriate and how to move an existing client onto it without friction.
Net 15 means the full invoice amount is due 15 calendar days after the invoice date. It is the same structure as Net 30 with half the credit period.
For the supplier, almost always — it halves how much cash is tied up in unpaid invoices. For the client it is tighter, so very large organisations with monthly payment runs may not be able to meet it regardless of willingness.
Do it at a natural boundary such as a new project or a rate review, state it in writing before the next invoice, and put the calendar due date on the invoice itself. Most clients accept without comment.
