Odoo migration done without the horror stories
Version upgrades (v14 → v19), Tally → Odoo, QuickBooks → Odoo, SAP B1 → Odoo. Zero data loss. Fixed price. Auditor sign-off.
We rescue stalled migrations and ship new ones. Senior consultants, parallel-run strategy, rehearsed cutover, 30 days of hypercare — and a written reconciliation report your auditor will accept.
What we migrate
From Tally spreadsheets to enterprise SAP — we've migrated nearly every ERP and accounting tool to Odoo.
Odoo Version Migration (v14 → v19)
Upgrade across any number of Odoo versions — including 5-version jumps. Custom modules ported, OWL frontend rewrites handled, data validated row-by-row.
Tally to Odoo Migration
Full historical Tally migration — ledger by ledger, voucher by voucher. Reconciled and audit-trail-preserved.
QuickBooks to Odoo
QuickBooks Online or Desktop → Odoo. Customers, vendors, accounts, transactions, attachments — full historical migration.
SAP B1 / NetSuite → Odoo
Migration off proprietary ERPs. We rebuild your customizations in Odoo, migrate historical data, and run parallel until your auditor signs off.
Zero-Risk Cutover
Parallel-run strategy — old system stays live while Odoo is built alongside. Rehearsed cutover with rollback plan. Most clients never need the rollback.
Migration on Fixed Timeline
We commit to your timeline in writing. Most migrations: 8–14 weeks SME, 12–20 weeks mid-market.
Why teams trust us with migrations they've already failed at
Zero data loss commitment
Row-by-row validation reports signed off by your auditor before cutover. We don't migrate without a clean reconciliation.
Custom modules ported, not abandoned
We don't tell you 'rewrite from scratch.' We port your existing custom modules to the new Odoo version — or honestly tell you when retiring is cheaper.
Parallel-run strategy
Your old system stays live until Odoo passes validation. Cutover weekend has a rehearsed rollback plan — used only if needed, and rarely is.
Fixed-price migration
We commit to a fixed price after discovery — no hourly billing surprises mid-migration.
30 days of hypercare
Senior consultant on-call 24/7 for the first 30 days post-cutover. Issues solved while you're still using yesterday's data as reference.
Auditor-validated
Big-4 and mid-tier auditors sign off on our migration reconciliations regularly. Your audit cycle won't be disrupted.

Frequently asked questions
Can you migrate across multiple Odoo versions in one jump?
Yes. We've migrated Odoo 13 → 19 in single projects. Multi-version jumps require careful custom-module porting and OWL frontend rewrites, but they're routine for us.
Will my custom modules break?
Some will — that's the nature of major Odoo upgrades. We assess every custom module during discovery, classify what's still in active use, and port/rewrite/retire each one. You see this plan before sign-off.
How long does Tally to Odoo migration take?
Most SME Tally migrations go live in 6–10 weeks including full historical data migration. Multi-year history can extend timeline by 2–3 weeks.
How do you guarantee zero data loss?
We don't ship without auditor-signed reconciliation reports. Every ledger balance, every open invoice, every inventory line is validated against the source system before cutover.
What's the cost of an Odoo migration?
Most SME migrations land between $8k–$40k all-in. Mid-market with significant custom code: $40k–$120k. Fixed quote after a free discovery consultation.
Do you support rollback if something goes wrong?
Yes — rehearsed rollback plan documented before cutover weekend. We've executed rollbacks twice in 12 years, both for reasons unrelated to migration quality (client-side network failures).
Stalled migration? Old version risk? Let's fix it.
