How it works
Your invoice number is assembled from three optional parts — a prefix, a date stamp, and a sequential counter — joined by your chosen separator.
- →Prefix — Your brand or client code: INV, ACME, 2026
- →Date stamp — YYYYMMDD locks each number to the day it was created
- →Counter + padding — Padding to 3 digits keeps numbers the same length (007, 008, 009)
- →Auto-reset — Counter resets to 1 each year or month — great for fiscal tracking
- →Copy & increment — One click copies and advances the counter for next time
- →Saves locally — Your format and counter persist in your browser — no account needed
