ERP Migration Cost Calculator

Migrating from SAP to Odoo typically costs $30,000-250,000 depending on data volume, complexity, and number of integrations. Simple migrations with under 10,000 records can be completed for $30,000-50,000. Complex migrations with full history, custom fields, and multiple integrations can cost $150,000-250,000. ECOSIRE has completed 100+ SAP-to-Odoo migrations.

Simple migrations (basic data, few integrations) take 2-4 months. Medium complexity migrations with custom fields and partial history take 4-8 months. Complex enterprise migrations with full historical data, regulatory requirements, and 8+ integrations can take 8-18 months. We recommend phased migrations to reduce risk and deliver value faster.

At minimum, migrate master data (contacts, products, chart of accounts), open transactions (unpaid invoices, pending orders), and current inventory levels. Historical data is optional — consider migrating only 2-3 years of transaction history and archiving older records. Regulatory requirements may mandate longer retention of financial records.

Yes, running systems in parallel for 1-3 months is strongly recommended. This allows you to validate that the new system produces correct results before decommissioning the old one. Run at least one full billing/closing cycle in parallel. The cost is typically $5,000-15,000/month but prevents costly errors during go-live.

The three biggest risks are: (1) Data quality issues — dirty data in the old system causes problems in the new one, (2) Integration failures — API connections that work differently in the new system, (3) User adoption — staff resistance to new workflows. Mitigate these with data cleansing before migration, thorough integration testing, and comprehensive training programs.
