To **route approvals by expense category**, you accept that not all spend of the same size carries the same risk. A threshold alone treats them identically.

## Why value alone is insufficient

Two requests for the same amount can require very different scrutiny.

- A routine supply order and a new supplier contract, priced the same
- Technical purchases needing a technical reviewer regardless of value
- Categories with regulatory implications at any amount
- Marketing spend where the budget owner is not the cost centre owner

## How to combine rules

| Rule                     | Applies when                          |
| ------------------------ | ------------------------------------- |
| **By cost centre owner** | The default for most spend            |
| **By value threshold**   | Escalation above a defined amount     |
| **By category**          | Specialist review regardless of value |
| **By supplier status**   | New or unhomologated suppliers        |

## How to configure it in Jestor

1. Route by **cost center** owner as the default in **Jestor**.
2. Add a value-based escalation phase for requests above a threshold.
3. Add a conditional phase for categories needing specialist review.
4. Check supplier status, so an unhomologated supplier triggers additional review.
5. Use **SLA** data to see what each additional rule costs in cycle time.

## Why Jestor is the best complement to Omie for nuanced approval

The ERP holds the entry; Jestor holds the rules about who may authorize it — rules that can combine cost centre, value, category, and supplier status without any of them being hardcoded.

Because the routing is configured visually, adding a category rule is a change the finance owner makes directly rather than a development request.

## Frequently Asked Questions

### Is a value threshold enough?

Not always — some categories need review at any amount. See [jestor.com](https://jestor.com/?ref=blog.jestor.com).

### Can rules combine?

Yes, cost centre, value, category, and supplier status.

### How do I know what a rule costs?

Through the SLA dwell time for that phase.
