What Is an Invoice and When Should You Send One?

How Do Payment Terms Work on Invoices?

Payment terms define when and how your client should pay the invoice. Common terms include:

3. Partial Payments: Allows clients to pay in installments.

Clearly stating payment terms avoids confusion and late payments. For regulatory guidance on payment practices, check Consumer Finance Protection Bureau.
