How to Map Expense Categories for Your ERP

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

Build the request form in Jestor with every field the ERP requires, marked required.
Use connected fields for supplier and cost center rather than free text.
Match the category list to the ERP's own, so no translation is needed at posting.
Register suppliers in Omie so they appear automatically as selectable.
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.
