Is 399Apps better than myBillBook for Indian small businesses?
Short answer
It depends on team size and which GST features you need. 399Apps is better for growing teams: unlimited users, e-invoicing and e-way bills are included from ₹399/month with full GST accounting (ledgers, P&L, balance sheet). myBillBook is a strong fit for a solo owner who only needs mobile GST billing — its Diamond plan (₹291/month billed annually) is cheap for one user. But the moment you need e-invoicing, e-way bills or a second user, myBillBook pushes you up to its Enterprise plan at ₹570/month — more expensive than 399Apps' unlimited-user plan at ₹399/month, and still capped at 3 users and 2 businesses. Even the mid-tier Platinum (₹333/month) unlocks godowns and a desktop app but leaves e-invoicing and e-way bills locked behind Enterprise.

Where 399Apps has the clear advantage
myBillBook only bundles e-invoicing and e-way bills into its Enterprise plan, now at ₹570/month for 2 businesses and up to 3 users. The Platinum tier (₹333/month) does unlock godowns and a desktop app, but e-invoicing and e-way bills remain absent — you still need to step up to Enterprise and pay more than 399Apps' unlimited-user plan. On 399Apps, e-invoicing, e-way bills and unlimited godowns are included from ₹399/month with no separate tier to unlock them.
User limits follow the same pattern: Diamond and Platinum are each capped at 1 user plus 1 CA per business, and even Enterprise tops out at 3 users. Add a billing clerk, an accountant and a branch manager and you are already past the ceiling. 399Apps includes unlimited users on every plan at ₹399/month for your first app, so headcount never changes the bill.
On accounting depth, 399Apps is built for full books: ledgers, P&L, balance sheet, GSTR-1 and GSTR-3B exports, TDS and e-invoicing. myBillBook is billing-first — strong for raising GST sales bills but its published plans do not list GSTR-1/GSTR-3B exports, so a separate accounting step is often still needed.
When myBillBook is the better fit
If you are a single user who only needs fast mobile GST billing — raising invoices, tracking receivables, printing bills at the counter — myBillBook's Diamond plan (₹291/month billed annually) is cheap for that use case. It is mobile-first, quick to set up, and widely used among shopkeepers and small retailers whose e-invoicing threshold is not yet triggered.
The calculus changes the moment you need e-invoicing, e-way bills, a second user, or P&L and balance-sheet reports. Upgrading to Platinum (₹333/month annual) adds a desktop app and unlimited godowns, but e-invoicing and e-way bills are still absent. To get those, you pay Enterprise at ₹570/month — capped at 3 users and 2 businesses — which is already more expensive than 399Apps at ₹399/month with unlimited users and e-invoicing included.
