Numbering & Format
Control how your invoice numbers are built, and what appears on every invoice.
Overview
Invoice numbering matters for bookkeeping and for looking established. Set the prefix, starting number, and padding once, and every invoice follows the same format.

Tips & Best Practices
Pick per-customer numbering only if your accountant asks for it. Account-wide sequential numbering is easier to reconcile and harder to duplicate.
