An automated purchase approval workflow with tiers ensures that every request goes through the right approver before becoming a purchase order or ERP entry. With Jestor, this process is configured without code and integrated directly with Omie or Conta Azul.

## Why does the purchasing process need approval tiers?

Purchases without tiers are purchases without control. Anyone can request any amount, and without a clear rule for who approves what, finance only discovers the problem when the payment has already gone out.

A well-structured approval workflow doesn't just control spending — it creates predictability and traceability for the entire purchasing operation.

## Common problems in unautomated purchasing workflows

- Requests arrive via WhatsApp or email with no standard format
- The wrong approver receives requests outside their tier
- New vendors requested without prior validation
- No traceability of how much was approved per department in a given period
- Rework to re-enter data in the ERP after informal approval

## How to automate the purchase approval workflow in Jestor

- Create the request process with fields for item, amount, vendor, and justification
- Define tier rules: each value range routes to a different approver
- Configure required validations before submission
- After final approval, Jestor posts automatically to Omie or Conta Azul
- View all purchases by department and period in the control dashboard
