Search for “best GST accounting software” and you will get a dozen confident rankings, most of them shaped by who paid for placement. The honest answer is that there is no universal winner. A single-counter retailer in a tier-2 town, a multi-state distributor, and a services agency all have very different needs. The useful question is not “which tool is best?” but “which tool fits how I actually work, and will keep working as GST rules change?”
This guide walks through the criteria that genuinely matter for Indian businesses in 2026, so you can evaluate any option — including LekhaPro — on your own terms rather than on a marketing claim.
Get the GST maths right first
Before anything else, the software must compute GST correctly. That sounds obvious, but it is where cheap billing apps quietly fail. For an intra-state supply, tax splits into CGST and SGST in equal halves; for an inter-state supply it becomes a single IGST. The place of supply rules — not just where you are registered — decide which applies. If the software gets this wrong, your invoices and your GSTR-1 will be wrong too.
A good tool also handles rounding the way the GST law expects (per-line and invoice-level), supports the standard rate slabs, tax-inclusive and tax-exclusive pricing, reverse charge, and cess where it applies. Ask to see a sample inter-state invoice and a reverse-charge entry before you commit.
Offline-first vs cloud: it is a real trade-off
Cloud accounting is convenient — access anywhere, automatic backups, easy multi-user collaboration. But it assumes a reliable internet connection and means your books live on someone else’s servers. For many Indian SMEs, especially in retail and manufacturing, billing simply cannot stop when the connection drops.
Offline-first software keeps your data on your own machine and works whether or not you are online, syncing or exporting when convenient. The trade-off is that you are responsible for backups and that remote access takes more setup. Neither model is universally better; decide based on your connectivity, your team’s location, and how much you care about holding your own data.
Look under the hood: real double-entry accounting
Many “accounting” apps are really invoice generators with a sales report bolted on. That is fine until your accountant asks for a trial balance, a proper profit and loss statement, or a balance sheet that actually balances. A real double-entry general ledger posts every transaction to ledger accounts, so your financial statements are derived from the books rather than estimated.
If you intend to grow, file income tax returns from the same data, or hand clean books to a CA, insist on genuine double-entry rather than a flat list of bills.
Inventory, if you sell goods
Businesses that hold stock need inventory that is tied to billing: stock that decrements as you invoice, valuation (FIFO or weighted average), batch or expiry tracking for sectors like pharma, and low-stock visibility. A services business can usually skip most of this. Match the depth of inventory features to what you actually sell so you are not paying for, or fighting with, machinery you do not need.
Returns: GSTR-1, GSTR-3B and GSTR-2B
Filing is where accounting software earns its keep. At minimum, the tool should assemble your outward-supply data into a GSTR-1-ready summary (B2B, B2C, credit/debit notes, HSN summary) and help you arrive at the figures for GSTR-3B. Reconciliation against the auto-drafted GSTR-2B — matching your purchase records to what suppliers actually reported — is what protects your input tax credit.
Be clear-eyed about how filing happens: some tools file directly via a GST Suvidha Provider, others produce JSON or summaries you upload yourself on the GST portal. Both are legitimate; just know which one you are buying.
Data ownership and exit
Ask the uncomfortable question early: if you stop paying, what happens to your data? You should be able to export your masters, vouchers and reports in a usable format at any time. Software that locks your books inside a proprietary format you cannot extract is a long-term liability, however polished it looks today.
Pricing — read what is actually included
Low headline prices often exclude the features that matter, then charge per user, per company, or per add-on. Compare on total cost for your real usage: number of companies, users, and whether GST returns, inventory and e-invoicing are included or sold separately.
For reference, LekhaPro’s plans are Basic at ₹249/month, Pro at ₹449/month, and Enterprise at ₹2,499/month — flat monthly pricing rather than per-seat surcharges.
A practical evaluation checklist
- GST-correct tax: automatic CGST/SGST for intra-state and IGST for inter-state, driven by place of supply.
- Deployment fit: offline-first for connectivity-sensitive businesses, cloud for distributed teams — chosen deliberately.
- Real double-entry ledger that produces a trial balance, P&L and balance sheet.
- Inventory depth matched to whether (and how) you sell goods.
- Returns support: GSTR-1 preparation, GSTR-3B figures, and GSTR-2B reconciliation for input tax credit.
- Data ownership: full export of masters and vouchers, no lock-in.
- Transparent, total-cost pricing — not a teaser rate with paid essentials.
Where LekhaPro fits
LekhaPro is an offline-first GST accounting and billing tool for Indian businesses, with a posted double-entry ledger, GST-correct invoicing, inventory, and GSTR-1/3B preparation with GSTR-2B reconciliation. It suits owners who value keeping their books on their own machine and want returns work and accounting in one place. It is not the right pick if you specifically need a fully cloud, browser-only product with a large team collaborating in real time — in that case a cloud-native option will serve you better.
The best way to decide is to test your own workflow: raise a real inter-state invoice, run a stock movement, and generate a return summary. The tool that handles your everyday work cleanly is the best one for you.
