Migration

Tally to Zoho Books migration, checked ledger by ledger

We load your data into a test Zoho organisation first, compare it with Tally, and give your CA a reconciliation report before you go live.

What gets compared

Trial balance, ledger by ledger
Customer and vendor ageing
Monthly GST summaries
Voucher counts by type

Scope of extraction and transfer

What we migrate

Scope is agreed in writing before we start. Typically it covers the following.

Masters
Chart of accounts, customers and vendors with GSTIN, PAN and addresses, stock items with HSN/SAC, units and GST rates.
Bill-wise open invoices and bills
With their due dates, not a single lump sum per party, so ageing works from day one.
Opening balances
For every ledger, including opening stock by quantity and value.
Multi-year history
Sales, purchases, receipts, payments, journals, credit and debit notes, if you want it inside Zoho Books.
Cost centres
From Tally, moved as reporting tags in Zoho Books.
Multiple GSTINs
And branches, each mapped to its own registration.
Foreign currency
Parties and transactions, with exchange rates carried over.
TDS and TCS
Ledgers and deductee details, so section-wise reports match your returns.

Not everything needs to move. Payroll, old audit adjustments and years nobody will query can stay in Tally. We tell you what each choice costs in effort.

Methodology

How we make sure nothing is lost

We do not promise accuracy. We show it, in three stages.

1. Practice load
We load a copy of your data into a separate test Zoho organisation. Mistakes happen there, not in your books.
2. Data checks before loading
Duplicate and near-duplicate ledgers, GST rate mismatches against HSN, negative stock, parties without GSTIN, unmatched bill references. Your CA decides what to merge or fix.
3. Reconciliation after loading
Trial balance ledger by ledger, customer and vendor ageing, monthly GST summaries, and voucher counts by type. Every difference is explained.

The output is a reconciliation report your CA can review and file with the working papers. It shows what matched, what was corrected, and who approved each decision.

Edge cases

Situations we handle

Mid-year switch
Cut-off at a month end, with the previous year closed in Tally.
Tally data with errors
Duplicate parties, wrong GST rates, ledgers under wrong groups. Found and listed before loading.
Many years of history
Year-wise loads, each year reconciled before the next.
Multi-branch
Several companies or GSTINs mapped into one organisation or separate ones.
Inventory and batches
Godowns, batch numbers, expiry dates, units of measure.
Partly paid bills
Receipts adjusted against the right invoice so the balance due is correct.
Parties that are both customer and vendor
One contact with both roles, balances not netted by mistake.
A Zoho organisation already in use
We merge without duplicating existing masters.

Timeline and effort

How long it takes

Most migrations take 1 to 5 weeks from the day we receive your data to handover. Where you land in that range depends on three things.

How many years of history you want, and how many vouchers each year has.
How clean the Tally data is. Duplicate parties and GST mismatches need decisions from you or your CA, and waiting for those decisions is usually the longest part.
Inventory, batches, branches and GSTINs. Each adds a check we run separately.

A services business with one GSTIN and current-year data can finish in days. We give you a go-live date, usually at a month or quarter start, after the readiness check.

1
Readiness check2 to 3 working days
You send a backup or exports. We report back what we found.
2
Practice load and data checks
Load into the test organisation. Issues list goes to you and your CA.
3
Fix, reload, reconcile
Decisions applied, data reloaded, comparisons run.
4
Cut-over and handover
Final entries loaded, report handed over, Zoho Books goes live. Tally stays read-only.

CA involvement

Your CA stays involved

A migration changes where the books live, not who is responsible for them. Your CA gets their own login with accountant access, sees the same trial balance and GST reports, and approves the merge decisions before we load.

The reconciliation report is written for their working papers. We never take over your CA's compliance work.

CA firms with clients on Tally can read how we work with CAs.

Common inquiries

Questions we get before a migration

Have a question that is not here? Book a call and we will go through it with you.

Can we switch from Tally to Zoho Books in the middle of a financial year?

Yes. Most clients do. We load the closing balances of the previous year, then the current year from 1 April to the cut-off date, and you start entering in Zoho Books from the next day. The trial balance at the cut-off date is matched with Tally before you go live. Our guide on switching software mid-year explains the dates to choose.

Will I still be able to open my old Tally data?

Yes. We never touch your Tally company. We work on a backup copy. After go-live you keep Tally read-only for reference and audit. We suggest keeping the backup of every migrated year safe, along with the licence or TallyPrime installation that can open it.

Will my GST returns continue without a break?

Yes. Returns already filed from Tally stay as they are. Before go-live we check that monthly GSTR-1 and GSTR-3B summaries in Zoho Books match the Tally figures for the months we migrate, so the first return filed from Zoho Books carries on from the same base. GST rate mismatches in old vouchers are flagged before loading.

Will my business be down during migration?

No. You keep working in Tally while we do the practice load and checks on a copy. The only pause is a short window at cut-over, usually a day or two, when we load the final entries and you hold new vouchers. We plan it around month-end and GST dates.

Is my data safe during migration?

We work on a copy of your Tally backup, never on your live company. The practice load goes to a separate test Zoho organisation, not your live one.

What if the trial balance does not match after the load?

We do not go live. We trace the difference ledger by ledger, usually to a voucher type, a GST ledger, a rounding setting or an unposted entry, fix it and run the comparison again. You get the report with the difference and the fix recorded. Our guide on trial balance mismatch lists the usual causes.

How much history should we move, one year or all years?

Closing balances plus open bills are enough for many businesses. Move full transactions if you need year-on-year comparison, GST history inside Zoho Books or one place for audit queries. Older years can stay in Tally. We tell you the effort difference in the written quote.

Do you migrate inventory with batches and godowns?

Yes. Stock items, units, opening quantities and values, batch-wise stock and godown-wise stock can be moved. Negative stock in Tally is cleaned up before loading, because it hides the real stock position.

Can we migrate into a Zoho Books organisation that already has entries?

Yes, but we first study what is already there. We check for existing customers, vendors, items and tax settings so nothing is duplicated, and agree the cut-off date so entries from both sides do not overlap. Reconciliation is then done on the migrated period only.
