Invoice App for Kirana Store

Kirana stores need an invoice app that: creates GST bills quickly, links to stock (so sales deduct inventory), tracks customer dues (udhar), and works offline. Stockkeeper is built for this—invoice app for kirana.

Invoice App vs Billing Software

The terms overlap. Invoice app = create invoices. Billing software = invoices + often stock + GST. For kirana stores, you need both invoicing and stock—so an inventory app or billing software that includes invoicing is the right choice.

GST Invoice Format

A proper GST invoice includes: your details, customer details, HSN codes, taxable value, CGST/SGST or IGST, and invoice number. See our GST invoice format guide for the full format. Good invoice apps auto-fill most of this.
