Verdict: 60 Odoo implementations in LATAM and what they all got wrong
2026-04-01 · 11 min · Sergei Filatov
I've audited 60 Odoo implementations across Peru, Mexico, Colombia, and Argentina. The same 8 mistakes repeat in every project. Here's the pattern — and the one fix nobody does.
The 8 mistakes
Across 60 audits, the same problems repeat — and they all stem from one root cause.
- Module overload — 12+ modules installed when 4 would do
- No fiscal localization sandbox — direct production updates
- Manual journal entries as workarounds for module gaps
- Custom dev without specs — undocumented behavior, breaks on upgrade
- Over-customized PoS — unmaintainable receipts and discounts
- Inventory not periodic — physical count never reconciles
- BI on production OLTP — slow reports, locked tables
- Backups untested — discovered when needed
The root cause
Every one of these comes from skipping the same step: a 2-week paid discovery + scoping phase before any installation.
