Free business tools for Indian shop owners

Running a small business in India involves constant calculations — GST on every sale, margin on every product, HSN codes on every invoice, and following up on payments from customers who buy on credit. These tasks take time every day, and errors in any of them can cause problems at the time of billing or GST filing.

These free tools are designed specifically for Indian shop owners, kirana stores, wholesale traders, freelancers and service providers. Whether you need to check the GST amount before raising an invoice, verify an HSN code for a new product, calculate how much margin you are making on a batch of goods, or draft a polite payment reminder for a customer — each tool handles one task clearly and instantly, without requiring you to create an account or download anything.

For shop owners who want to go beyond one-off calculations, the Ledgerly GST Billing App automates GST calculation, invoice generation and customer ledger management in one place. The Khata App tracks all customer credit and payments, so you always know who owes what. And if you run a small business that also needs inventory tracking, the Ledgerly billing software for small businesses brings billing, stock, payments and reports together in a single app available on Android and web.
