Picking the right billing tool as a small business owner is not just about the price tag — it is about how quickly you can start, whether GST is genuinely covered, how well the mobile app works, and whether the support team actually responds. Here are our top picks for 2026 and what makes each stand out.
1. Deccan Bill — best all-round pick
Free forever plan, real GST compliance out of the box, mobile-first POS, and priority WhatsApp support in English / Hindi / Telugu. Built in Banjara Hills, Hyderabad, for Indian SMBs. See the full feature set on our Features page.
2. Zoho Books / Zoho Invoice
Excellent accounting depth if you already live inside the Zoho ecosystem. Slightly heavier onboarding and a steeper learning curve for pure shopkeepers.
3. Vyapar
Very popular mobile-first billing app for micro businesses. Free tier is limited on the desktop; Pro plan is billed yearly.
4. Marg ERP
Feature-rich for chemists and distributors, but the desktop-first UX feels dated on mobile. Best when you already have a full-time back-office team.
How to choose
- Is it truly free at your current scale? See our Free Billing Software page for what "free" really means.
- Does it produce GST-ready GSTR-1 & 3B?
- Does the mobile POS work on a ₹6,000 tablet?
- Is customer support reachable on WhatsApp?
If you tick more than two boxes above for Deccan Bill, start free.
