Before answering **do you need to replace your ERP**, separate the complaints. The accounting and fiscal side is rarely the problem. The complaints are almost always about everything surrounding it.

## What the complaints usually are

Listed plainly, most of them are not accounting problems at all.

- 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 adapt to how the team works

## Migration or expansion?

| Complaint                  | Requires migration?                       |
| -------------------------- | ----------------------------------------- |
| **Missing approvals**      | No — add a layer before the entry         |
| **No custom apps**         | No — build them alongside                 |
| **No AI**                  | No — add it in the operational layer      |
| **Wrong accounting model** | Possibly — this is a genuine ERP question |
| **Unsupported tax regime** | Yes — this belongs to the ERP             |

## How expansion works 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 as apps, 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 integration is native, with no middleware in between — and the division is explicit: the ERP keeps accounting, invoicing, and tax, while Jestor covers the request, approval, and process layer.

That is the point of expansion: keep the system that works and cover the gaps, rather than migrating something that was never the problem.

## Frequently Asked Questions

### Does Jestor issue invoices or calculate tax?

No — those stay with the ERP. See [jestor.com](https://jestor.com/?ref=blog.jestor.com).

### Will I have to migrate data?

No, expansion means keeping the ERP in place.

### When is migration genuinely necessary?

When the accounting model or tax regime is the problem.
