**Cost allocation across departments** works when every expense references a real cost centre record. Reporting by department then becomes a filter rather than a reconstruction.

## Why departmental reporting is usually painful

Allocation is often applied at closing, by someone interpreting descriptions written weeks earlier.

- Expenses allocated retrospectively, from memory
- Departments disputing charges they never saw
- No visibility of committed spend before invoices arrive
- Reallocation work every month for the same recurring costs

## What proper allocation requires

- **A cost centre record** per department, with an ID and a name
- **An owner** on each centre, who approves against that budget
- **A status**, so retired centres stop appearing on new requests
- **A required allocation field** on every expense record
- **Reporting per centre**, available continuously rather than monthly

## How to configure it in Jestor

1. Build the cost centres table in **Jestor** with a sequential ID, name, status, and responsible users.
2. Add a connected field on the expense table pointing at cost centres.
3. Make it required, so no expense enters the process unallocated.
4. Route approvals to the centre's owner automatically.
5. Build a dashboard panel showing approved value per **cost center**.

## Why choose Jestor for departmental control?

Because allocation runs on connected records in **Jestor**, a department's spend is always one filter away — no consolidation, no interpretation, and no monthly reallocation exercise.

Approved expenses can post to the **ERP** with their cost centre already attached, so finance does not reclassify anything after the fact.
