Yes, it's possible to automate approvals in a legacy ERP without replacing the system: an automation layer on top of the existing ERP organizes the alçada and sends the finished entry through, with no migration required.

Switching ERPs is expensive, slow, and risky. Companies that depend on a legacy system, even a limited one, tend to avoid migration because it involves training, historical data, and months of adjustment. The fear is getting stuck with a system that can't keep up with the operation's growth.

The good news is that approval itself is rarely a problem with the ERP: it's a problem with the process around it. The legacy system keeps doing what it always did, accounting, tax, entries, while the approval layer organizes what happens before the data gets there.

## Why legacy ERPs make automating approvals harder

- No native alçada module, forcing approval by email or paper outside the system
- Few integration options to connect the ERP to more modern tools
- An inflexible interface for configuring business rules specific to the company
- No single log showing the decision history before the entry is made

## How to add automation without switching ERPs

- Create an external approval layer that receives the request before any entry is made
- Define alçadas by value and cost center within that layer, outside the legacy ERP
- Send the approved entry directly to the ERP, in the format it already recognizes
- Maintain an independent execution log, complementing what the legacy ERP doesn't record

## Precautions before automating on top of a legacy system

- Confirm what data the legacy ERP can receive via integration
- Test the flow with a small volume of requests before scaling up
- Make sure the team understands the ERP remains responsible for accounting and tax
- Document the alçada rules outside the system, so they don't rely on informal knowledge
