Number series of each document
Each kind of document has its own series, for example INV/26-27/001 for invoices and QT/26-27/001 for quotations. Each business gets its own series, and the serial starts again from 1 every financial year.
Step by step
- Open Settings. My data › Settings. Or press Change number series under the number box in any maker.
- Invoice (Billing). Under Invoice numbering set Prefix, Digits in the serial number and Add the financial year (26-27). The line The first invoice of a year will be shows the result.
- Other documents. Under Number series of each document each document has a small card (Selling, Buying, Money, rent and salary, Shops and trades) with its prefix and the next number.
- Save. New documents use it at once. Old documents keep their numbers.

Rules and dates
Rule 46(b) of the CGST Rules: a consecutive serial number of up to 16 characters, unique for a financial year, using letters, numbers, hyphen and slash. "INV/26-27/001" is 13 characters.
Common mistakes and how to fix them
- Changing the prefix in the middle of the year. Allowed, but keep the serial running and tell your accountant; never reuse a number.
- A prefix longer than 16 characters with the year and digits. Keep the prefix short (3–4 letters).
