Tally to Odoo Migration Overview

📌 TL;DR - Tally to Odoo Migration Services at a Glance

Migration from Tally to Odoo is the structured transfer of your chart of accounts, contacts, items, godowns, and opening balances from desktop Tally into Odoo ERP, with Indian GST localization configured so accounting, inventory, and compliance run on one platform. Patron Accounting delivers a CA-verified migration from INR 9,999 (Exl GST and Govt. Charges).

Thousands of Indian SMEs are moving from Tally to Odoo to run accounting, inventory, sales, and compliance on a single ERP. Migration from Tally to Odoo is more than an accounting switch: ledger groups must map to a Schedule III chart of accounts, godowns must map to warehouses, and GST settings must be localized before go-live.

Patron Accounting has supported businesses for 15+ years and verifies every migration against the source trial balance. Our team maps Tally ledgers to the Schedule III chart of accounts and configures GST, so your Odoo books reconcile from go-live.

What Is Migration from Tally to Odoo

Migration from Tally to Odoo is the process of exporting accounting and operational master data from Tally and importing it into Odoo ERP so that Odoo becomes the primary system of record. The core data set includes the chart of accounts, customers, vendors, items, godowns, and opening balances drawn from the Tally Trial Balance.

Odoo is a unified, double-entry ERP that connects accounting with inventory, sales, purchase, and HR. Its Indian localization supports GST, TDS, TCS, e-invoicing, and e-way bill, with a chart of accounts template aligned to Schedule III of the Companies Act, 2013.

Key Terms for Tally to Odoo Migration:

Cutover Date: The go-live date on which Odoo becomes the primary system and new transactions are entered only in Odoo.

Opening Balance: The closing balance of each ledger in Tally as on the cutover date, posted into Odoo as the starting position.

Schedule III Chart of Accounts: The statutory account structure under the Companies Act, 2013, used by Odoo's Indian localization.

Parallel Run: A 2 to 4 week period where Tally and Odoo run together to build team confidence before full switchover.

Pair your migration with the right ongoing support:

Legal and Compliance Framework

Under Section 36 of the CGST Act, 2017, every registered person must retain books of account and records for 72 months from the due date of the annual return. A migration must preserve historical records so they remain available for audit and assessment, which is why full history is typically archived in Tally as read-only.

Odoo's Indian localization supports GSTR-1 and GSTR-3B preparation and e-invoicing under the GST framework administered by the Goods and Services Tax portal. Its chart of accounts follows Schedule III of the Companies Act, 2013.

Frequently Asked Questions

Common questions about migrating from Tally to Odoo ERP, data, GST localization, and timelines.

What data can be migrated from Tally to Odoo?

Odoo supports importing the chart of accounts, customers, vendors, products with HSN codes, godowns, and opening balances from Tally. Current-year vouchers can be migrated for GST continuity, while full transaction history is typically archived in Tally as read-only. Patron Accounting handles mapping, GST localization, and trial balance reconciliation.

Can historical transactions be migrated to Odoo?

Historical transactions are usually not migrated line by line. Opening balances capture the net position at cutover, and current financial year vouchers are imported to maintain GST filing continuity. Older history remains accessible in Tally as a read-only archive, which also satisfies record retention requirements.

How much does Tally to Odoo migration cost?

Patron Accounting migration starts from INR 9,999 (Exl GST and Govt. Charges) for up to 1,000 transactions. Final fees depend on transaction volume, years migrated, and ERP scope such as inventory, multi-company, and integrations. Call +91 945 945 6700 for a free quote.

How long does the migration take?

An opening-balance migration is usually completed in 1 to 2 weeks. A full ERP cutover with inventory and current-year transactions typically runs 4 to 8 weeks, and complex multi-company migrations can take 10 to 12 weeks. We plan the cutover at the start of a month to keep GST filing clean.

Does Odoo support Indian GST, TDS and TCS?

Yes. Odoo's Indian localization supports GST with CGST, SGST, and IGST, plus TDS, TCS, e-invoicing, and e-way bill. It prepares GSTR-1 and GSTR-3B and uses a chart of accounts template aligned to Schedule III of the Companies Act, 2013, so statutory reporting stays compliant.

Will my CA and accounting team adapt to Odoo?

Yes. Odoo Accounting uses the same double-entry principles as Tally, so teams adapt quickly. We map familiar Tally workflows to Odoo equivalents, such as voucher entry to journal entry, and run a parallel period so your team and CA gain confidence before full switchover.

What is the difference between Tally and Odoo?

Tally is desktop accounting software focused on bookkeeping and statutory reports. Odoo is a cloud-capable ERP that unifies accounting with inventory, sales, purchase, CRM, and HR. Migrating to Odoo gives a single source of truth and connected operations, while Tally remains a reliable read-only archive.
