What this is
TZAP Blog is the tools and knowledge platform of TZAP Marketing OPC Private Limited, a one-person company registered in West Bengal (CIN U63999WB2024OPC268590). We publish two things: free calculators that do a specific job properly, and guides that explain the reasoning behind them.
Why we built it
Most Indian business calculators online are wrappers around an ad unit. They give you a number without telling you where it came from, they get the GST split wrong, and half of them assume you are in the United States. We needed better tools for our own client work, so we built them and made them public.
How we fund it
The tools are free and always will be. There is no signup, no usage cap and no paid tier. TZAP Blog exists because some of the people who find a useful calculator go on to hire TZAP Marketing for digital marketing, websites or growth work. That is the entire business model, and it is why you will find one soft link to our services and no display advertising anywhere on this site.
What we will not do
- Publish thin pages generated at volume to chase keywords
- Run display ads or accept paid placements inside guides
- Ask for your email before showing you a result
- Send your data anywhere — every calculator runs entirely in your browser
Who writes it
Content is written by Gour Paul and the TZAP Marketing team, drawn from work with Indian small businesses on marketing, compliance and product. Where a guide covers regulated territory such as GST or tax, it states what the law says and recommends professional advice for your specific situation.
