IndianBusinessTools – Invoicing & compliance tools for Indian businesses (no signup, no watermark)

Built this because every time I needed to raise a GST invoice, check an HSN code, or work out professional tax for a different state, I ended up on five different sites — half of them paywalled after the third use.

IndianBusinessTools (indianbusinesstools.com) is a free set of tools for that stuff:

- GST calculator (updated for the GST 2.0 rate changes — 0/5/18/40% slabs)

- Invoice, quotation & purchase order generator — PDF or Excel, GST or non-GST

- HSN/SAC code finder

- TDS & professional tax calculators (state-wise)

- Import/export duty calculator with landed cost breakdown

- Rent agreement & business letter generator, MSME/Udyam checklist, e-way bill helper

No signup, no watermark, and everything runs in your browser — nothing you type gets uploaded anywhere.

Would love feedback, especially from anyone who does this stuff for a living (accountants, shop owners, freelancers) — what's missing, what's wrong, what you'd actually use.
