Both produce a trial balance. That is not the difference.
This question usually gets answered with a feature list, which is why it stays confusing. Good accounting software in India does a great deal: GST invoicing, e-invoicing, e-way bills, inventory, payroll, banking. Tally has done most of that for years.
The difference is the direction the data flows. In accounting software, a person reads a document and enters it. In an ERP, the document is created by the operation itself and the accounting entry follows automatically.
The same event, in both
| Step | Accounting software | ERP |
|---|---|---|
| Goods arrive | Storekeeper writes it in a register | Storekeeper records a goods receipt against the PO |
| Stock updates | Later, from the register or the bill | Immediately, by batch and bin |
| Quality check | Outside the system | Stock held in QC until passed or rejected |
| Vendor bill | Entered by accounts from the paper bill | Matched against the receipt; differences flagged |
| Accounting entry | Made by a person | Posted by the system when the bill is matched |
| If quantities disagree | Found at month-end, if at all | Found at the gate, by the person holding the goods |
Where accounting software runs out
Accounting packages tend to stop at the point where the question is operational rather than financial. These are the questions that usually force the move.
- "Which batch went to which customer, and what did the QC reading say?" — traceability across documents, not just a batch field on a stock item.
- "What is on the shop floor right now, and which operation is it at?" — production execution, not a bill of materials.
- "Can we accept this order for next Tuesday?" — capacity and availability, not a stock figure.
- "Why did this job cost more than we quoted?" — costs gathered against a job as it happens.
- "What did the field team do yesterday?" — activity that never touches a voucher.
When accounting software is the right answer
For a large number of Indian businesses it is, and switching would be a waste of money and disruption. If your operation is buy-and-sell with a single location, if stock is simple, if nobody needs to see anything they cannot already ask for, then a good accounting package plus discipline beats an ERP you will only half-use.
The point at which that stops being true is usually not a size threshold. It is a complexity threshold: multiple locations, batches you must trace, work that passes through stages, or people who need to see things without asking.
In short
- Accounting software records financial events; ERP runs the operations that create them.
- In an ERP the ledger entry is a consequence of the operational document, not a separate act of data entry.
- The move is usually forced by an operational question — traceability, capacity, job cost — not by an accounting one.
- If your operation is simple, good accounting software is the right answer and switching is a waste.
