We built a suite of free tools to make GST and pricing simple for online sellers. Here's what each one does.

By the Launch My Office team · Updated 2026-06-22 · 5 min read

Running an online business means juggling tax codes, rates, duty and pricing. Our free tools page brings the essentials together so you can answer everyday questions in seconds — no sign-up, no cost.

How they work together

Find a product's rate with the HSN finder, set a clean MRP with the reverse GST calculator, check landed cost with the import duty calculator if you import, then confirm your registration footprint with the multi-state checker. Estimate your tax for the year with the income tax calculator.

Why we made them free

Most sellers don't need a consultant to answer a quick HSN or pricing question — they need a fast, reliable tool. When you do need expert help with registration, we're a tap away on WhatsApp.
