**ERP expansion** means adding the processes your **ERP** does not cover — approvals, custom internal apps, **AI** — while leaving the accounting and fiscal core exactly where it is. The migration project that usually follows a list of complaints becomes unnecessary.

## Why teams start considering a migration

The trigger is almost never the accounting side. It is the surrounding processes.

- No approval step before entries are posted
- No way to build an internal app for a process the ERP never anticipated
- No **AI** support for repetitive data entry and classification
- Rigid screens that cannot be adapted to how the team actually works

## What stays where, in an expansion model

- **The ERP keeps**: accounting entries, invoicing, tax calculation, financial reconciliation, the fiscal record
- **The expansion layer covers**: request capture, approval routing, operational dashboards, internal apps, document reading
- **They share**: clients, suppliers, products, cost centers, and companies, through a native connection
- **Nobody migrates**: no data export, no parallel run, no retraining on a new accounting system

## How to set this up in Jestor

1. Connect **Jestor** to the existing **ERP** — natively for **Omie** and Conta Azul, or through the open **API** and webhooks.
2. Map the processes the ERP does not cover today.
3. Build them as apps, using ready templates or by describing the process in text and letting AI generate it.
4. Route approvals before anything posts back to the ERP.
5. Add dashboards on the operational data, without a separate BI tool.

## Why choose Jestor to expand your ERP?

**Jestor** is positioned as the operating system for the processes around the ERP rather than a replacement for it. One client replaced 19 spreadsheets with standardized workflows, and customer operational efficiency has increased by roughly 35% after adoption.

The platform holds SOC 2 Type I and II certification, with regular penetration testing and access auditing — relevant when the expansion layer touches financial data.
