A **purchase approval workflow integrated with the ERP** starts with a structured request, goes through an authorization tier, and only then generates the posting in the ERP. In **Jestor**, this flow is built with **Pedidos de Compra** (Purchase Orders) natively connected to **Omie**, without spreadsheets or a middleman.

## Why does the purchasing process tend to get stuck at approval?

Many companies treat purchasing as haggling for a discount the moment a need shows up. Without a structured process, the company loses traceability over what was spent, with whom, and when, and can't analyze its own purchasing data later.

## What companies are trying to solve?

- Purchase requests scattered across email or **WhatsApp**, with no centralized history
- No automatic alert when a request has been stuck for too long
- Rework from manually posting every approved purchase in the ERP
- Difficulty comparing quotes before approving

## How does the Jestor–ERP purchasing integration work?

The request is created in **Jestor**, goes through the right tier, and once approved is sent automatically to the ERP Expansion connected to Omie.
