- Assist with DB-level verification when allowed: run/read SQL queries to confirm imports, detect duplicates, and compare expected vs actual figures;

- Collaborate with developers/BA/PM to clarify requirements and confirm fixes (including re-testing after data fixes);

- Support client communication when needed (e.g., explaining import errors, data cleanup steps, validation results);

- Validate data imports and migrations:

• check templates, required fields, formats, and mapping logic;
• verify imported results in Odoo (counts, duplicates, relationships, totals);
• troubleshoot common import issues (wrong encoding, missing references, wrong data types, constraint errors).

- Create and maintain test documentation:
