Migration
Tally did its job. The question is whether it still fits the one you have now.
Most Indian businesses start on Tally for good reason. Some outgrow it. Here is how to tell which you are, and what moving actually involves.
First
When Tally is still the right answer
Be honest about this first.
If you operate from one location, hold modest inventory, do not manufacture, and your team is comfortable, Tally is a capable and economical system. Replacing it would cost money and change habits without returning much. We would tell you so.
The case for moving is not that Tally is poor software. It is that some operating models outgrow what any accounting package is designed to do.
The signals
Several of these usually appear together
The common thread is that the business has processes the accounting system was never meant to hold, so people hold them instead.
Stock is argued about
Warehouse figures and accounts figures disagree, and reconciling them is somebody’s monthly job.
Production is estimated
Consumption is recorded after the fact rather than as it happens.
Costing lives in Excel
Job or project profitability is calculated outside the system, weeks later.
Branches send data
Consolidation is manual, and the group position is always slightly out of date.
Approvals happen on WhatsApp
And are reconstructed into the system afterwards, if at all.
Payroll is separate
It posts as a single monthly journal, so labour cost never reaches the job.
What changes
What an ERP adds
Not better accounting. Different scope.
Inventory with batch, expiry, serial and multi-warehouse control that posts its own valuation. Production with bills of material, work orders and actual consumption. Projects with committed and actual cost against budget. Approval workflows that are configured rather than remembered. Payroll integrated to cost centres. Role-based access so the right people see the right numbers. And an audit trail that exists because the system recorded it.
GST, e-invoicing, e-way bill and TDS continue to work as you expect — that part is table stakes, not the reason to move.
Migration
What actually happens
Typical timeline for a mid-sized business is eight to sixteen weeks.
Masters first
Ledgers, stock items and parties migrate with their balances, after review for duplicates and missing attributes.
Opening balances
Migrated as at a chosen cut-off date and reconciled to signed control totals. Your trial balance must agree before anyone proceeds.
History decision
Most businesses migrate two or three years and retain Tally read-only for anything older. Migrating a decade is possible, rarely necessary, and adds cost.
Parallel run
One to two months where both systems produce the same month and you compare, line by line.
Cutover
At a financial year or quarter boundary where possible, with our team alongside yours for the first close.
Be careful
Three things go wrong most often
Dirty data stays dirty
Duplicate ledgers, stock items with no unit, parties with no GSTIN — these need attention before migration, and that work belongs to you rather than to us.
Expect a dip
Users who know Tally keyboard shortcuts in their fingers will be slower for a few weeks. Budget for training.
Not in March
A migration attempted in the last week of the financial year is a migration attempted at the worst possible time.
Will we lose our Tally history?
No. Masters and opening balances migrate as at a chosen cut-off date. Most businesses migrate two or three years of transaction detail and retain Tally in read-only form for anything older.
How long does migration take?
Typically eight to sixteen weeks for a mid-sized business, driven mostly by how clean the existing data is and how quickly decisions get made.
Can we run both systems in parallel?
Yes, and we recommend it. Expect one to two months where both produce the same month and you compare before cutting over.
Is there a best time of year to move?
A financial year or quarter boundary is easiest, though not essential. The last week of March is the worst possible time.
A conversation before a proposal.
Tell us how you operate and what is not working. If Tally still fits, we will say so — it costs us an hour and saves you a great deal.
