# Odoo Enterprise vs. a custom-built ERPStack system

**Typical Odoo Enterprise license cost:** $5,000 - $30,000+ / year
**Lock-in risk:** Medium (Open-source base, but proprietary apps locked behind subscriptions)
**Modularity:** Medium (Module dependency graph is tightly coupled)
**Customization ceiling:** Moderate (Python/XML inheritance limitations)
**Migration path:** API-level sync and migration to serverless Next.js modules

## Feature comparison

| Feature | ERPStack (custom) | Odoo Enterprise |
| --- | --- | --- |
| Framework | Next.js & React (Modern) | Python & QWeb (Legacy XML) |
| Edge Computing | Native Vercel Edge Support | Not supported natively |
| Code Ownership | 100% Client Owned | Vendor Owned (Custom Apps) |
| Headless Architecture | Yes | No |

## Migration timeline

- **Data Profiling** (1 Week): Map Odoo models to relational PostgreSQL schemas.
- **API Sync** (2 Weeks): Bi-directional sync via XML-RPC/JSON-RPC.
- **UI Replacement** (4 Weeks): Replace Odoo views with high-performance React components.
- **Database Cutover** (1 Day): Final migration to standalone PostgreSQL.

## Hidden costs of Odoo Enterprise

- **App Dependencies:** Installing one free app often requires installing three paid Custom apps.
- **Hosting Limitations:** Odoo.sh limits database access and custom Python package installations.

## Why teams leave

- Moved from Odoo to our stack to build a truly headless e-commerce experience, doubling conversion rates. (A D2C consumer brand — Slow frontend performance and restrictive hosting.)
