Invoice numbering customization
Use templates with tokens to generate exactly the invoice number format you want.
Available tokens
| Token | Replaced with | Example |
|---|---|---|
{PREFIX} | INV / QUO / CN based on type | INV |
{YEAR} | 4-digit year | 2026 |
{YY} | 2-digit year | 26 |
{MONTH} or {MM} | 2-digit month | 05 |
{DAY} or {DD} | 2-digit day | 09 |
{SEQ} | Auto-incrementing 3-digit number | 001 |
{SEQ:4} | Custom-width sequence (4 digits) | 0001 |
{CLIENT} | Customer initials (max 4 chars) | JD |
Common formats
| Template | Output |
|---|---|
{PREFIX}-{SEQ} | INV-001 (default) |
{YEAR}-{SEQ:4} | 2026-0001 |
INV-{YEAR}-{MONTH}-{SEQ} | INV-2026-05-001 |
{PREFIX}-{YY}{MM}-{SEQ} | INV-2605-001 |
{CLIENT}-{YEAR}-{SEQ} | JD-2026-001 |
Setting up
Settings → Numbering Format. Three independent fields: invoice, quote, credit note. Each has a live preview as you type.
⚠ Existing invoice numbers don't changeAlready-created invoices keep their original numbers. Only NEW invoices use the updated format.
Avoiding collisions
If you switch from INV-{SEQ} to {YEAR}-{SEQ:4} mid-year, the sequence restarts at the highest existing count. Invoicely auto-detects collisions and increments the sequence until it's unique.
