How Invoice Numbering Works
Invoisor automatically generates sequential invoice numbers
Auto-Increment Feature
Every time you create an invoice, the system automatically increments the invoice number. For example:
- First invoice: INV-1001
- Second invoice: INV-1002
- Third invoice: INV-1003
Customizing Invoice Prefix
You can change the prefix from "INV-" to anything you like:
- Go to Settings
- Scroll to Invoice Settings
- Change the Invoice Prefix field
- Click Save
Example prefixes: INVOICE-, 2026-, CLIENT-INV-, etc.
Changing the Next Invoice Number
If you need to start from a different number:
- Go to Settings
- Find Next Invoice Number
- Enter the desired starting number
- Click Save
⚠️ Note: This only affects future invoices, not existing ones.
Best Practices
✓ Start with 1001
Makes your business look more established
✓ Include the Year
Use prefixes like "2026-" or "INV-2026-" for easier tracking
✓ Keep it Consistent
Don't change your format mid-year for accounting purposes
