We have published TZAP Blog & Tools: thirty-five free calculators covering GST and tax, business finance, digital marketing, social media and everyday utilities.
Why we built it
Most Indian business calculators online are wrappers around an advertising unit. They give a number without showing the working, several get the CGST and SGST split wrong, and a surprising number assume you are in the United States. We needed better tools for our own client work, so we built them and made them public.
What is different
- Every calculation runs in your browser. Nothing you type is uploaded, logged or stored.
- No signup, no usage cap, no paid tier. The tools are free and will stay free.
- No display advertising. Not now, not later.
- Each tool shows its formula and a worked example with real rupee figures, so you can check the result rather than trust it.
What comes next
Supporting guides for each tool, starting with the GST cluster. The tools are built; the writing is the work now.
