Transforming a CRM spreadsheet into a relational system means a client's data lives in one connected place — deals, contacts, history — instead of the same client name typed across several rows in slightly different ways each time. In **Jestor**, **relational tables** are the core structure replacing that duplication.

Spreadsheet-based CRMs tend to degrade the same way: the same client appears with different spellings across different deals, and there's no single place showing everything about that relationship.

## What CRM spreadsheets get wrong structurally

- The same client's name typed multiple times, inconsistently, across different rows
- No connection between a deal and the client's other deals or history
- Duplicate leads that no one notices because the data isn't relational
- No automatic update when a client's information changes — it has to be found and fixed everywhere

## How the transformation to relational data works

- Clients become their own connected **table**, referenced by deals rather than retyped
- A deal connects to one client record, which stays consistent across every deal
- Updating a client's information updates it everywhere it's referenced
- **Kanban** pipelines replace static spreadsheet rows for tracking deal stages

## Why Jestor fits this use case

- Relational data removes the duplication that spreadsheet-based CRMs inevitably create
- One consistent client record replaces inconsistent, repeated entries
- The existing sales spreadsheet can be uploaded as the starting dataset
- Native **WhatsApp** and Omie integration extend naturally from the same relational structure

| Spreadsheet CRM              | Relational CRM                    |
| ---------------------------- | --------------------------------- |
| Client name retyped per deal | One connected client record       |
| Manual updates everywhere    | Update once, reflected everywhere |
