CatsBill review
A free web invoicing tool for GST billing, stock tracking, and payment records.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
CatsBill is a cloud-based GST billing application for Indian small businesses, emerging businesses, accountants, and self-employed users. Its Free plan supports GST-compliant invoice creation, automatic CGST, SGST, and IGST calculations, inventory and stock tracking, bill listings, payment tracking, and GST return reporting with input tax credit calculation. Users can download, print, share, and export invoices, while cloud backup supports access from computers or tablets through the web.
The pricing is straightforward: CatsBill is presented as lifetime-free software, and its listed Free plan includes GST-compliant invoices, inventory management, bill listings, invoice download, printing and sharing, and cloud backup. The plan also covers the product’s core billing functions, including payment tracking, GST reports, input tax credit calculation, bill export, and cloud backup. For a small business that needs essential GST invoicing and stock records without a paid tier, the pricing structure keeps the product easy to evaluate.
CatsBill’s strongest fit is a focused web-based workflow for creating invoices and maintaining related records. It brings tax calculation, stock tracking, bill management, payment records, and GST reporting into one service, but its scope is narrower where recurring billing, online payments, reminders, integrations, and mobile platforms are important. Choose CatsBill if free GST billing and basic inventory tracking are the priority. Businesses needing connected apps, automated reminders, recurring invoices, or broader platform access should choose an alternative with those capabilities.
