★ A note from the makers
We built GSTEasy because most GST billing apps on the Play Store charge a monthly fee or upload your data to their servers. We thought Indian shopkeepers deserved better. So we made one that's free, ad-free, server-less, and offline-first. If you like it, tell another shopkeeper. That's all the marketing budget we have.

Made in India for Indian businesses.
