Building a custom CRM without a developer means creating a customer relationship management system that reflects exactly your company's processes — without adapting the business to the tool, and without hiring a technical team to do it.

## Why off-the-shelf CRMs don't always work

Generic CRMs are designed to cover as many scenarios as possible. That makes them broad — but often too generic for operations with specific processes. The result is that teams end up using only 20% of the system and maintaining parallel spreadsheets for the rest.

The most common problems:

- Fields and stages that don't reflect the company's actual sales process
- Impossible to connect the CRM to the operational process that comes after the sale
- Customizations require an enterprise plan or expensive development
- CRM data isolated from financial and operational systems

## What a no-code custom CRM needs

- **Configurable fields:** add or remove fields without code
- **Editable pipeline stages:** reflect the real sales process
- **Follow-up automations:** notify the owner, create tasks, send messages
- **ERP integration:** deal closed → accounts receivable created automatically
- **Connection with post-sale:** on close, automatically triggers the onboarding process

## Why Jestor solves this

Jestor has a native CRM module with opportunity management — and the advantage of being on the same platform as operational processes. This means a CRM built in Jestor is not isolated: it's part of the company's entire operating system.

With Jestor:

- Any manager builds the ideal CRM for their sales process without code
- When an opportunity is closed, automations trigger onboarding and create ERP records
- WhatsApp is integrated — each conversation with a prospect becomes a trackable card
- CRM fields connect to contracts, projects and support tables

## Where Jestor stands out in custom CRM

- Native CRM with direct integration to the operational pipeline and the ERP
- AI App Builder: describe the CRM you need and AI creates the base structure
- WhatsApp integrated as a prospecting and relationship channel
- Native integration with Conta Azul — closed deal automatically creates accounts receivable

## How to apply it in Jestor

1. Define your sales process stages (e.g.: Prospected → Proposal → Negotiation → Closed)
2. Create the CRM pipeline in Jestor with those stages and necessary fields
3. Configure follow-up automations: "if card has had no movement for X days, notify the owner"
4. Connect the CRM to the onboarding pipeline so post-sale starts automatically
5. Activate WhatsApp to centralize communication with prospects on the same card

## FAQ
