Tally to Odoo migration — the painless way
Full historical ledger migration. GST-compliant. CA-signed reconciliation. Fixed-price, 6–10 weeks.
Most SMEs outgrow Tally between 30–80 employees. We migrate the entire history, configure GST/e-way bill in Odoo, get your CA's sign-off, and cut over without losing a single voucher.
What we migrate from Tally

GST-Aware
Indian GST tax structure, HSN/SAC codes, e-way bill compatibility, GSTR-1/3B mapping — pre-configured for Odoo Accounting India.
Inventory + Masters
Stock items, units, locations, batches, opening stock — migrated with valuation methods preserved (FIFO/avg-cost).
CA-Validated Reconciliation
Trial balance, ledger summaries, open AR/AP reports — generated side-by-side from Tally and Odoo before cutover.

Frequently asked questions
How long does Tally to Odoo migration take?
Most SME migrations: 6–10 weeks including full historical data, GST configuration, CA sign-off and 30-day hypercare. Multi-company groups with 5+ Tally instances: 10–14 weeks.
Will I lose my Tally history?
No. We migrate every voucher across every year. Your team can run any historical report in Odoo — and we keep your Tally backup safely archived as a belt-and-braces measure.
Does it handle Indian GST correctly?
Yes — we configure Odoo's Indian GST localization with your HSN/SAC codes, tax groups, e-way bill integration and GSTR-1/3B mapping. Validated with your CA before sign-off.
How much does it cost?
Most SME Tally migrations: $8–25k all-in. Multi-company / multi-currency / heavy customization: $25–60k. Fixed quote after a free discovery consultation.
Can we keep Tally running in parallel for a while?
Yes — parallel-run is the default. Tally stays live while Odoo is built, validated, and signed off by your CA. Cutover only happens when you're fully confident.
What about Tally customizations / TDL files?
If you have custom TDL reports or invoices in Tally, we rebuild equivalent functionality in Odoo (using Odoo's reporting engine + custom modules). Always cheaper to rebuild on Odoo than try to replicate TDL.
