# From Excel to a real system: a migration plan without stopping the business

> Move from Excel to an integrated system when several people enter the same data in different files, reports run late, or discrepancies keep recurring. A safe move happens in stages: clean the data, run one module in a short parallel period, train, then expand gradually.

## Signs you’ve outgrown Excel

Excel is excellent for analysis, but it isn’t a shared database with permissions and an audit trail.

- Files named “final_2_edited”
- Several people editing one file and losing changes
- The monthly report takes days to assemble
- No one knows who changed a number or when
- Branches send files in different formats

## The five-step migration plan

- Inventory current files and pick the source of truth for each data type.
- Clean data: standardise item and customer names, remove duplicates.
- Choose the first module (often inventory or sales) tied to accounting.
- Run in parallel for two to four weeks and compare results.
- Train each role, then officially retire the old files.

## The biggest mistake: migrating the mess as-is

If you migrate 3,000 items with duplicates and typos, the new system inherits the same problem. Budget time to clean data before migrating — it’s often the most important step in the whole project.

## Frequently asked questions

### Can we keep Excel for analysis afterwards?

Yes. Reports can be exported to Excel whenever needed.
