The **signs your ERP needs an expansion layer** are recognizable because they cluster around the same gap: everything that happens before an entry exists.

## The recurring complaints

Listed plainly, none of them are accounting problems.

- **Spreadsheets multiplying** around the ERP to cover gaps
- **Approvals happening outside any system**, then posted manually
- **No internal app** for a process the ERP never anticipated
- **No AI support** for repetitive entry and classification
- **Screens that cannot adapt** to how the team actually works

## What belongs where

| Layer               | Owns                                                                     |
| ------------------- | ------------------------------------------------------------------------ |
| **ERP**             | Accounting entries, invoicing, tax, the fiscal record                    |
| **Expansion layer** | Request capture, approval routing, operational dashboards, internal apps |
| **Shared**          | Clients, suppliers, products, cost centres                               |

## How to set it up in Jestor

1. Connect **Jestor** to the existing **ERP** — natively for **Omie** and Conta Azul, or by **API**.
2. Map the processes the ERP does not cover today.
3. Build them from templates, or by describing them to the **AI** builder.
4. Route approvals before anything posts back to the ERP.
5. Add dashboards on the operational data, without a separate BI tool.

## Why Jestor is the best complement to Omie rather than a replacement

The connection is native, with no middleware between the systems, and the division is explicit: the ERP keeps accounting, invoicing, and tax while Jestor covers the operational layer around them.

One client replaced 19 spreadsheets with standardized workflows — and those spreadsheets are exactly the symptom this layer removes.

## Frequently Asked Questions

No, those stay with the ERP.

### What is the clearest sign?

Spreadsheets multiplying around the ERP.
