Transforming a supplier spreadsheet into a structured registry means each supplier gets one consistent record, connected to contracts and purchase history, instead of the same supplier appearing multiple times with slightly different names. In **Jestor**, this uses a validated, relational table structure.

Supplier spreadsheets drift the same way almost every time: someone adds a new row for a supplier that already exists, just spelled slightly differently, and nobody notices until reporting breaks.

## What supplier spreadsheets get wrong

- The same supplier entered multiple times with inconsistent naming
- No validation catching an obvious duplicate before it's created
- No connection between the supplier row and their contracts or purchase history
- Categories applied inconsistently, making filtering unreliable

## How the transformation into a structured registry works

- Upload the existing supplier spreadsheet as the starting dataset
- Add validation rules to catch potential duplicates going forward
- Connect supplier records relationally to contracts and purchase requests
- Standardize categories through defined **option fields**, not free text

## Why Jestor fits this use case

- Migration starts from existing supplier data, cleaning up structure as it moves
- Structured, validated intake reduces future duplicate entries
- Supplier records connect to contracts and purchasing, not siloed
- Consistent categorization makes filtering and reporting reliable

| Supplier spreadsheet            | Structured registry              |
| ------------------------------- | -------------------------------- |
| Inconsistent naming, duplicates | Validated, de-duplicated entries |
