An **operational layer between the ERP and the business** exists to add flexibility to flows the ERP doesn't cover — approvals, CRM, checklists — without touching the tax and accounting side. **Jestor** works as that operational layer, with **BPMS** to model processes and native integration to the ERP via **ERP Expansion**.

## Why doesn't the ERP alone cover day-to-day operations?

ERPs like **Omie** and Conta Azul are rigid by nature: they handle the tax and accounting side well, but weren't built for operational processes that change often, like expense approval, onboarding, or internal support.

## What business teams are trying to solve?

- Processes that depend on a spreadsheet running alongside the **ERP**
- No flexibility to adjust a flow without opening a ticket with IT
- Difficulty giving visibility into processes that cross more than one area
- Rework from manually feeding the ERP with data that already exists somewhere else

## How does this operational layer relate to the ERP?

**Jestor** organizes the process and feeds the ERP; the ERP stays responsible for tax and accounting execution.

| Layer                      | Responsibility                  | Example                                           |
| -------------------------- | ------------------------------- | ------------------------------------------------- |
| ERP (Omie, Conta Azul)     | Tax and accounting execution    | Bank reconciliation, invoicing, income statements |
| Jestor (operational layer) | Structures the business process | Approvals, CRM, checklists, Service Desk          |
| Native integration         | Connects the two layers         | Automatic posting after approval                  |

## Why choose Jestor?

- **BPMS** allows modeling and automating custom processes with no code
- Integration with the ERP is native, with no Zapier, Make, or other middleman
- The company gains operational flexibility without giving up the ERP it already uses
