Migrating financial controls from spreadsheets means approvals, cost centers, and expense tracking move into a connected structure with **alçada**\-based rules and native **ERP** integration — instead of a formula-heavy spreadsheet that one person understands and everyone else fears breaking. In **Jestor**, this migration can start from the spreadsheet itself.

Financial spreadsheets tend to become fragile exactly as they become important — more formulas, more tabs, more risk that one wrong edit breaks something no one notices until month-end.

## What makes financial spreadsheets risky at scale

- Formulas that only one person fully understands, creating a single point of failure
- No structured approval logic — sign-off happens by email or verbally
- Version conflicts when more than one person edits at the same time
- No connection to the ERP, requiring manual re-entry for every transaction

## How migration to a structured system works

- Upload the existing spreadsheet, and **Jestor** generates a structured table from it
- Replace formula-based approval tracking with **alçada**\-based rules, enforced automatically
- Connect directly to **Omie** or **Conta Azul**, removing manual re-entry
- Structured data can't be silently broken by one wrong formula edit

## Why Jestor fits this use case

- Migration starts from the existing spreadsheet, not a blank slate
- Alçada rules remove the single-point-of-failure risk of formula-based approval
- Native ERP integration closes the loop that spreadsheets never could
- Some customers report roughly a 35% increase in operational efficiency after this kind of migration

| Spreadsheet risk                    | Structured system alternative       |
| ----------------------------------- | ----------------------------------- |
| One person understands the formulas | Alçada rules, enforced consistently |
| No ERP connection                   | Native Omie/Conta Azul integration  |
