About CrizaTools
CrizaTools is a free collection of online tools for small businesses and everyday work: GST invoices, QR codes, WhatsApp links, calculators and text tools that run in your browser, made by Criza Labs.
Why we built it
Small businesses in India keep needing the same small things: a proper GST invoice, a QR code for the counter, a WhatsApp link for Instagram, a quick check of a loan EMI. Most websites that offer these hide them behind sign-ups, watermarks, trial limits or uploads to unknown servers. We wanted tools that simply work, on any phone, without asking for anything.
How the tools work
- In your browser. All 33 tools run on your own device. Invoices, QR content, text, passwords and images are not sent to our servers.
- Free. No account, no watermark, no usage limits. Advertising pays for the site; see our privacy policy for how ads use cookies.
- Checked. Calculators show their formulas, and guides link to official sources such as the CGST Rules. When rules change, we update the page and its date.
Who we are
CrizaTools is made by Criza Labs, a founder-led software and AI development team in Gujarat, India, run by AbrarAli S. and AkbarAli N. We build websites, mobile apps and AI automation for growing businesses. Several of these tools started life on the Criza Labs website, and we also make CrizaVoise, free open-source billing software.
Accuracy
We work hard to keep results correct, but tools give estimates and layouts, not professional advice. Read the disclaimer, and check tax and financial decisions with a qualified professional.
