Zoho Books is a serious accounting tool — you may not want to leave it entirely. Most of our customers keep Zoho Books for day-to-day invoicing and add FilingLab for CA-led compliance. Here is the export-and-mirror playbook, plus the harder “full migration to Tally” path if you want it.

Kick-off & mode selection
Two paths: (A) keep Zoho Books, layer FilingLab on top via API for compliance, or (B) full migration to Tally. We pick on the kick-off call based on transaction volume and team familiarity.
Trial balance + ledger-wise export
In Zoho Books: Reports → Trial Balance → Export PDF/CSV for FY start and current date. Reports → Account Transactions → run for full FY → Export. Reports → e-Invoice → IRN register → Export. We grab all three.
Chart-of-accounts re-mapping
Zoho Books COA differs from Tally’s default. We map every ledger head (Indirect Expense > Marketing → Tally’s Indirect Expenses; Zoho’s “Tax Payable” group → Tally’s Duties & Taxes). 60-100 line mapping for a typical SMB.
e-invoice IRN history preservation
Zoho Books holds your full IRN register. We export it as CSV (Sales → e-Invoices → Filter → Export) and ingest it into our compliance dashboard. Already-issued IRNs are valid forever (GSTN-issued); we just need them queryable.
Zoho One ecosystem teardown decisions
If you are on Zoho One (CRM + Books + Payroll + Inventory + Sign + Expense), we audit each module: keep / replace / drop. Most customers keep CRM and Inventory, replace Payroll with our HR module, drop Sign in favour of Aadhaar e-sign.
Parallel run + reconciliation
If you chose option A (keep Zoho), we run a one-month parallel — your team books in Zoho, we file from imported data, you cross-check one GSTR-3B side by side. Option B: Tally goes live, Zoho cancelled.
Pre-migration checklist
Most items are 60 seconds to find. We start the migration faster if you have these ready.
Zoho Books admin login (or invite us as Accountant)
Where:books.zoho.in → Settings → Users & Roles → Invite User (Accountant role suffices)
Full FY trial balance (PDF + CSV)
Where:Zoho Books → Reports → Trial Balance → Date range = full FY → Export both formats
Account-transaction export for full FY
Where:Zoho Books → Reports → Account Transactions → Run → Export CSV
e-invoice IRN register (if applicable)
Where:Zoho Books → Sales → e-Invoices → Filter by date → Export CSV
GSTR-1 / 3B filed JSON for last 4 quarters
Where:Zoho Books → Returns → GSTR-1 / 3B → Download filed JSON
Zoho One subscription details (if applicable)
Where:one.zoho.com → Admin Console → Subscription — module-by-module list
Tally licence (if going full-migration path)
Where:New: tallysolutions.com → Buy. Existing: serial number from Tally → Help → About
Export trial balance, account transactions, and IRN register from Zoho Books (or via Zoho API if volume requires)
Map Zoho Books COA to Tally groups — published 60-line mapping table; you approve before import
Preserve e-invoice IRN history so old invoices remain auditable after Zoho cancellation
Audit each Zoho One module and recommend keep / replace / drop
If keeping Zoho Books: integrate via API token for read-only data sync into our compliance dashboard
File Zoho Books / Zoho One subscription cancellation with pro-rata refund request
Your GSTIN, e-invoice IRP credentials and GSTN linkage are unchanged — Zoho only stores them
Already-issued e-invoice IRNs remain valid forever (issued by NIC IRP, not Zoho)
Customer-facing invoice numbering can be preserved or restarted — your call, we configure either
Bank-feed connections (Zoho Books Auto-Pull) re-establish with Tally Bank Sync if you migrate fully
Gotchas & honest fixes
These are real situations we have hit in past Zoho Books migrations. We name them up front so they do not surprise you.
The gotcha
Zoho Books export is CSV-by-default, but Tally needs XML/Tally-Definition-Language for cleanest import. CSV import works but loses voucher-type detail.
Our fix
We run a custom CSV-to-Tally-XML transformer (open-source: tally-xml-converter) that preserves voucher types (Sales, Purchase, Receipt, Payment, Journal). Avoids the “everything becomes a Journal Voucher” problem.
The gotcha
You use Zoho Books Inventory module — SKU-level stock and HSN mapping. Tally has Inventory but COA-to-Stock linkage differs.
Our fix
We export stock summary (Zoho → Inventory → Reports → Stock Summary) and rebuild it in Tally Inventory with the same HSN/GST rate mapping. Takes 1 extra day for catalogues over 500 SKUs.
The gotcha
Zoho One bundles you can’t partially cancel — if you drop Zoho Books, the rest of Zoho One (CRM, Mail, etc.) recalculates as standalone subscriptions, which is sometimes more expensive.
Our fix
We do the math: a typical 5-user Zoho One customer drops to Zoho CRM Standard + Zoho Mail standalone is Rs.1,750 vs Zoho One Rs.4,000. Sometimes — rarely — keeping the full bundle and just using Books less is cheaper. We share the numbers honestly.
The gotcha
You set up Zoho Sign integration for vendor PO approvals — the signed PDF history sits inside Zoho Sign, not Books.
Our fix
Zoho Sign exports signed documents individually (Zoho Sign → Documents → Bulk Export → Email me ZIP). For active workflows, we either preserve Zoho Sign standalone (~Rs.700/month) or migrate to Leegality / DocuSign with template re-creation.
What it costs
Migration free on annual plans. Tally licence is Rs.18,000 one-time if you do not already have one (we waive setup fee if you purchase via us). Zoho refund: pro-rata for unused annual months, typically lands in 14-30 days. If running parallel, expect 30-45 days of dual subscriptions.
Frequently asked
Yes — this is option (A) and ~40% of our Zoho Books customers choose it. We pull data via Zoho API daily, file GSTR-1/3B and ROC returns ourselves. You keep the Zoho UI your team knows.
Custom reports are platform-specific and do not export cleanly. In Tally we rebuild the top 5 reports you actually use (we ask which ones in the kick-off). The rest are usually unused legacy from earlier needs.
If you keep Zoho Books (option A), yes. If you full-migrate to Tally (option B), no — but your CA is now us, so the question is moot. Your old CA loses access on the day Zoho cancels.
Preserved in Tally Inventory + Accounting. Same COGS computation logic (FIFO/Weighted Average) works; only the UI differs.
Yes. We export salary register, Form 16, PF/ESI register, and TDS quarterly returns (24Q) from Zoho Payroll. Our HR module imports these and continues processing from the next pay cycle.
Often not yet. The Zoho Books free tier is genuinely good. We usually recommend you wait until you cross the Rs.25L threshold and Zoho starts charging — or until compliance (ROC, TDS, notices) becomes non-trivial.
