How this looks in TiBook
How to
- 1Open Settings → Company.
- 2Click Manage Prefixes (or find Document Prefixes on mobile settings).
- 3Set a prefix for each type: sales invoice, quote, purchase invoice, purchase order, sales return, credit note, debit note, delivery challan, proforma, and expense.
- 4TiBook tracks the next number per type. New documents auto-increment only that series.
- 5You can still edit a number on an individual voucher before save if you need to fix a gap.
- 6Save prefixes once per company. New vouchers pick them up immediately.
Why separate series matter
GST audits and buyers expect invoice numbers to be consecutive within a series. Mixing quotes and invoices in one sequence creates confusion — separate prefixes make reports readable at a glance.
Financial year changes
Many firms reset or add a year token (e.g. INV-25-) each April. Update prefixes in settings; TiBook does not auto-reset — you control the next number.
Agree prefix rules with your CA before issuing your first outward invoice of the year.
