Accounting Software for Small Business in India: How to Choose Without Getting Locked In
- Four GST features are non-negotiable: automatic place-of-supply so IGST versus CGST+SGST is never hardcoded, Rule 46 compliant invoices, GSTR-1 and 3B output, and GSTR-2B reconciliation.
- Ask where the data physically lives and how you export it before you enter a single voucher — migration pain, not licence fees, is the real cost of a wrong choice.
- Run the same five real transactions through every shortlisted tool: an inter-state sale, a credit note on it, an RCM expense, a part-payment, and a month-end close with a period lock.
Most small businesses in India pick accounting software because their accountant uses it, then discover two years later that the data cannot leave, the GST output needs manual fixing every month, or the licence now costs more than the bookkeeping. This is a practical evaluation guide: the features that are genuinely non-negotiable under Indian GST, the questions about data that matter more than features, and a test script you can run in an afternoon.
The GST features you cannot compromise on
| Requirement | Why | How it fails in practice |
|---|---|---|
| Automatic place-of-supply | Whether a sale is IGST or CGST+SGST depends on supplier state versus place of supply, decided per invoice | Tools that let the user pick the tax type produce months of wrongly-split tax that only surfaces in GSTR-9 |
| Rule 46 invoice format | A tax invoice must carry the prescribed particulars, including HSN/SAC, the tax split and reverse-charge indication | Pretty templates missing the GSTIN of the recipient or the HSN column; the buyer's credit is then at risk |
| Credit and debit notes linked to the original | A credit note must reverse tax in the same heads as the original invoice | A credit note on an inter-state sale that reverses CGST and SGST instead of IGST — a classic reconciliation break |
| GSTR-1 and GSTR-3B output | Returns should come out of the books, not be retyped | Summary figures that do not tie to the ledger, so someone reconciles by hand every month |
| GSTR-2B reconciliation | Input credit is only available if it appears in 2B and is accepted in the Invoice Management System | Tools that record purchase tax as credit regardless of what the supplier filed, overstating available ITC |
| Reverse charge handling | RCM creates an output liability and a corresponding credit | Only one leg recorded, so the liability is understated |
| E-invoice and e-way bill readiness | Thresholds keep moving down as turnover grows | Discovering at the threshold that the tool cannot generate an IRN |
If a demo cannot show the first and the third of those in two minutes, stop the evaluation.
The question most people ask last: where does the data live?
This matters more than any feature, because it decides what happens when you are unhappy.
- Local / on-device. Data stays on your machine. No subscription dependency, works offline, nothing to breach server-side. The trade-off is that backups are your job and multi-user access is limited — so a disciplined backup routine, ideally to your own cloud drive, is mandatory.
- Cloud, multi-user. Access from anywhere, your accountant works in the same file, roles and approvals are possible. The trade-offs are the subscription and the fact that your records sit in someone else's infrastructure, which the DPDP framework makes your responsibility to understand.
- Either way, ask three things: can I export the complete books — ledgers, vouchers and masters — in a readable format, on demand, myself? What happens to the data if I stop paying? Who at the vendor can read it?
A tool you can walk away from with your data intact is worth more than a longer feature list. The usual lock-in traps are export restricted to the vendor's own format, read-only access after cancellation, and an "export" that produces reports instead of transaction data.
A five-transaction test script
Put the same five entries through every shortlisted tool. It takes twenty minutes per tool and tells you more than a month of brochures.
- Inter-state sale — Delhi to Haryana, ₹1,00,000 at 18%. Expect ₹18,000 IGST and nothing in CGST or SGST, with place of supply recorded on the invoice.
- Credit note on that invoice for ₹20,000. Expect IGST to reduce by ₹3,600 — not a CGST and SGST reversal.
- An RCM expense, say legal fees from an advocate. Expect both an output liability and an input credit to appear.
- A part-payment of ₹50,000 against the sale. Check the debtor ageing now shows ₹30,000 outstanding in the right bucket, and that the receipt is not double-counted as income.
- Month-end close — reconcile the bank, then lock the period. Try to edit a locked entry; it should refuse. A tool with no period lock will let someone change last quarter's filed numbers.
Then ask for the trial balance and confirm debits equal credits, and that the GST summary ties to the ledger without manual adjustment.
What small businesses actually use
Be honest about scope. Most businesses under a few crore of turnover need: sales and purchase entry, a compliant invoice, bank and cash, debtor and creditor ageing, GST output, basic inventory if they trade goods, and a profit and cash view. They do not need multi-currency consolidation, job costing or a full ERP, and paying for those is how software budgets get wasted. Match the tool to the next eighteen months, not to an imagined future.
Common mistakes
- Letting the software decide the tax split. Place of supply is a legal determination per invoice; any tool that treats it as a dropdown will eventually get it wrong at scale.
- No period lock. Filed figures that can still be edited mean your GSTR-3B and your books diverge silently.
- Treating purchase tax as credit without 2B. Credit exists when the supplier files, not when you pay.
- Keeping the only copy in the accountant's login. Books are the business's records; if you cannot export them yourself, you do not control them.
- No backup routine for local software. On-device is a privacy advantage and a single point of failure at the same time.
- Choosing before running real transactions. Every tool demos well on a cash sale; the inter-state credit note is where they separate.

What GST features must accounting software have in India?
Automatic place-of-supply determination so IGST versus CGST plus SGST is decided per invoice rather than picked from a dropdown, Rule 46 compliant tax invoices with HSN or SAC, credit and debit notes that reverse tax in the same heads as the original, GSTR-1 and GSTR-3B output that ties to the ledger, GSTR-2B reconciliation, and reverse-charge handling that records both the liability and the credit.
Is local or cloud accounting software better for a small business?
Local keeps the data on your own device with no subscription dependency and nothing to breach on a server, but backups are your responsibility and multi-user access is limited. Cloud gives shared access and roles but puts your records in someone else's infrastructure. Either is defensible; what is not is being unable to export your complete books on demand.
How do I avoid lock-in with accounting software?
Before entering a single voucher, confirm that you can export complete transaction data and masters yourself in a readable format, find out what access you retain if you stop paying, and test the export in the trial. Lock-in usually appears as export limited to the vendor's own format, or an export that produces reports instead of transactions.
Does accounting software need a period lock?
Yes. Once a month has been filed in GSTR-3B and the TDS return is in, the underlying entries should not be editable. Without a lock, someone correcting an old voucher silently makes your books disagree with your filed returns, and that mismatch surfaces much later in GSTR-9 or an assessment.
