To **map expense categories for your ERP**, the request form has to collect exactly what the accounting entry requires. A field missed at entry becomes a manual step at posting.

## Why entries fail to post cleanly

Teams that fail to **map expense categories for your ERP** usually designed the request for the requester, not for the entry it produces.

- Category chosen from a list that does not match the ERP's
- Cost centre left optional, then applied retrospectively
- Supplier entered as text rather than selected
- Company not specified in a multi-entity group

## What the request must carry

| Field           | Why the entry needs it                     |
| --------------- | ------------------------------------------ |
| **Value**       | As currency, so thresholds and totals work |
| **Cost centre** | Determines allocation and routing          |
| **Category**    | Must match the ERP's own list              |
| **Supplier**    | Selected from a registry, not typed        |
| **Company**     | Required where several entities exist      |
| **Dates**       | Issue and due, as date fields              |

## How to set it up in Jestor

1. Build the request form in **Jestor** with every field the **ERP** requires, marked required.
2. Use connected fields for supplier and **cost center** rather than free text.
3. Match the category list to the ERP's own, so no translation is needed at posting.
4. Register suppliers in **Omie** so they appear automatically as selectable.
5. Confirm the first few entries posted correctly before rolling the process out.

## Why Jestor is the best complement to Omie for clean entries

Once you **map expense categories for your ERP**, the integration is native, with no middleware — so a request carrying the right fields becomes a payable without anyone re-entering anything.

Because suppliers and clients registered in the ERP appear automatically, the selection lists stay aligned without a synchronization routine.
