Do not carry the old mess into the new system
Most source data has the same customer three times, item codes that mean different things in different years, and accounts nobody has used since 2019. We profile all of it and hand you a report, so you decide what merges, what is renamed and what is left behind.
- A duplicate and blank-field report before any load
- Naming and merge rules agreed by your team
- Cleaning applied in staging, never in production
