Structuring purchasing and supply processes with BPM means requests, supplier selection, and approval all run through one connected flow — instead of separate spreadsheets for suppliers, purchase requests, and budget tracking. In **Jestor**, this connects a structured supplier registry, **alçada**\-based approval, and native **Omie** integration.

Purchasing breaks down most visibly at the handoff points: between requesting something and comparing suppliers, and between approval and actually recording the purchase in the ERP.

## What fragments purchasing processes

- Purchase requests submitted informally, without a consistent format
- Supplier comparison happening manually, outside any structured record
- No visibility into budget impact before a purchase is approved
- Manual re-entry between approval and the ERP

## How structured purchasing works

- Purchase requests go through a standard **form**, connected to relevant budget data
- Multiple supplier quotes can be compared within the same request
- **Alçada** rules route the approval based on value and cost center
- Approved purchases post directly into **Omie**

## Why Jestor fits this use case

- Supplier comparison, approval, and ERP posting all share the same connected structure
- Budget impact is visible before approval, not discovered afterward
- Native Omie integration removes the manual re-entry step
- The same structure scales from routine supply orders to larger capital purchases

| Purchasing step     | How BPM structures it                  |
| ------------------- | -------------------------------------- |
| Supplier comparison | Multiple quotes within one request     |
| Approval            | Alçada-routed by value and cost center |
