Is 399Apps better than myBillBook for Indian small businesses?

399Apps vs myBillBook at a glance

How 399Apps (Nidhi Books) compares with myBillBook for Indian SMBs. Prices exclude GST.

Pricing reflects publicly listed plans and is indicative; verify current pricing with each vendor.

Where 399Apps has the clear advantage

myBillBook charges per user per year on its paid plans (Diamond from ≈ ₹3,599/user/year +GST). Add two or three people — your billing staff, an accountant, a branch manager — and that cost compounds quickly. 399Apps includes unlimited users on every plan at ₹399/month for your first app (prices exclude GST), 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 — excellent for raising GST sales bills but lighter on the accounting side. Once you need proper accounts or a CA to audit your books, you will feel that difference.

Billing cycle is another split: myBillBook is annual-only, while 399Apps is monthly from ₹399 (annual available on request). For a new business, monthly means you are not locked into a year upfront.

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 — the myBillBook free or Silver plan is hard to beat at its price. It is mobile-first, quick to set up, and widely used among shopkeepers and small retailers.

The calculus changes the moment you add a second person, need a CA to access your books, or want P&L and balance-sheet reports beyond billing summaries. At that point, paying per user per year on myBillBook plus a separate accounting tool often costs more than 399Apps with everything included.
