Invoices and documents

Document numbering

How each Brand numbers invoices, estimates, notes and receipts — and how to continue from your old system.

2 min readUpdated 26 October 2026About This Feature

Each Brand has its own number series for each kind of document. A document gets its number only when it’s finalized, and issued numbers never change.

  1. Brand — each Brand’s series are separate.
  2. Prefix — like BD-INV-; the next number follows.
SeriesExample
InvoicesBD-INV-0121
EstimatesBD-EST-0043
ProformasBD-PI-0012
Credit notes · Debit notesBD-CN-0008 · BD-DN-0005
ReceiptsRCT-0093
Delivery notes · ChallansBD-DLN-0019 · BD-DC-0004
  1. Open Settings → Numbering

    Choose the Brand.

  2. Set the prefix and next number

    For example, continue from 0482 if your old system ended at 0481.

  3. Save

    The next finalized document uses it.

GST-valid numbers

With GST invoicing on, invoice numbers must be 16 characters or fewer, using letters, digits, - and /. Settings → GST checks every GST series and offers a GST-valid format with the financial year, like BD27/26-27-0042. See GST registrations and numbering.

Common questions

Why didn’t my draft get a number?

Drafts are numbered only when finalized — so deleted drafts never leave gaps.

Can two Brands use the same prefix?

Each Brand should have its own prefix so customers and your accountant can tell them apart.
