ChaiBooks
Web app, for AD Enterprises
GST invoicing with HSN codes, GSTR-3B reports and e-way bills.
We process over 150 invoices through it now and the tax accuracy is spot on.
Web apps and SaaS are software your business or your customers log in to: dashboards, billing and invoicing systems, internal tools and products you sell. It is for businesses that have outgrown spreadsheets or want to sell software of their own. A first version takes 6 to 8 weeks from the signed scope, designed, built and handed over running.

Thirty minutes with the founder about the problem, not a pitch.
What we build, what we do not, the price and the date.
Full payment against the written scope. No hourly billing.
We ship, show you how it runs, and stay on if you want us to.
