Tally is accounting and billing software that most Indian businesses and their CAs know well. An ERP runs the operations behind the numbers (orders, stock, production, purchase, field sales and approvals) and keeps the books as a result. Businesses usually move when work outside Tally, in Excel and WhatsApp, becomes the bigger problem.
What Tally does well
It is worth being fair: Tally is popular for good reasons. It handles vouchers, ledgers and GST returns well, it is fast for experienced users, and almost every Indian CA knows it. TallyPrime also covers inventory with godowns and batches, e-invoicing and e-way bills. For a trading business with a small team, one location and simple stock, it can be all the software needed.
Signs you have outgrown it
The problem is rarely Tally itself. It is the work that grows up around it, outside it:
- Orders live outside the books. Sales orders sit in Excel or WhatsApp until someone keys them into Tally as invoices.
- Production is planned on sheets. BOMs, work orders and material planning happen in Excel, so cost per unit is estimated.
- Purchase has no approval trail. Requests and approvals happen on calls and messages.
- Field teams are invisible. Visits, orders and collections from the road come in as messages at night.
- Too many people need different access. Sales, stores, production and accounts each need their own screens and permissions.
- Reports are compiled, not live. Someone exports data every week to build the owner's report.
Side by side
| Area | Accounting software (e.g. Tally) | ERP (e.g. BeatOS ERP) |
|---|---|---|
| Books and GST | Strong: vouchers, ledgers, GST returns | Ledgers, GST and returns built from operational documents |
| Sales orders and CRM | Basic orders; no lead pipeline | Leads, quotations, orders, schemes, credit holds |
| Manufacturing | Basic BOM and stock journals | Multi-level BOMs, production plans, work orders, job cards, costing |
| Purchase | Purchase vouchers | Requests, supplier quotes, approvals, receipts matched to bills |
| Field sales | Not included | Beat plans, GPS-verified visits, orders and collections on Android and iOS |
| Approvals and roles | User rights | Workflow approvals by amount, role-based screens |
This compares typical use. Tally's features change with each release, so check current capabilities with Tally or your Tally partner.
Can you run both?
Yes, for a while. Some businesses run operations in an ERP and keep the books in Tally, sending invoices and payments across. It works, but it means two sets of masters (customers, items, ledgers) to keep in step. Most move the accounts into the ERP once the team is comfortable, so there is a single set of numbers.
How to move without losing your books
- Pick a cut-off date, usually the start of a month or financial year.
- Export from Tally the masters (customers, suppliers, items), the trial balance, stock summary by godown and batch, and outstanding bills.
- Clean on the way: merge duplicate parties, fix GSTINs, states and HSN codes.
- Trial load into a copy of the ERP and match totals against Tally's own reports.
- Final load with closing figures, and sign off only when the trial balance, stock value and receivables match.
This is the method we follow in BeatOS data migration.
