# ChatGPT for small business

Connect ChatGPT Business, Enterprise or Edu to your business's inbox, calendar, invoices and books. It acts through Conecto and pays per action.

Give this to your agent: `Set up Conecto from https://conecto.chat/SKILL.md, then show me what you can run for our business.`

## Example: `calendar_book`

Request: "Book Rachel Kim in for the 11:30 bike fitting on Saturday the 24th. Her email is on her contact card."

The documented reply of `calendar_book` ($0.01), for Halverson Cycle & Repair, a bike shop with a repair workshop in Portland, Oregon (https://conecto.chat/tools/calendar/calendar_book.md):

## How it works

1. **Add the server**: In ChatGPT Business, Enterprise or Edu: Plugins, then Add custom MCP server. Address: https://api.conecto.chat/v1/mcp
2. **Sign in once**: You tick the areas it may use, and it runs on a key of its own with a daily budget.
3. **Ask** (`calendar_book`, $0.01): Pick it with @ in a chat, then ask. For example: "Book Rachel Kim in for the 11:30 bike fitting on Saturday the 24th. Her email is on her contact card."

## What it costs

Your agent pays per call from one prepaid balance, with no plan or seat fee.

## Questions

### Is ChatGPT safe for business data?

Through Conecto, ChatGPT sees only what the tools it calls return. Each connection has its own key, a daily budget and a log of every call, and you can hold risky actions for your approval or remove the connection at any time.

### Can ChatGPT send emails?

On ChatGPT Business, Enterprise or Edu, yes, once it has an inbox. Conecto gives it one on your business's own subdomain, or lets it send from your Gmail or Outlook mailbox.

### Which ChatGPT plans can connect Conecto?

OpenAI's help center allows custom MCP servers that take actions on ChatGPT Business, Enterprise and Edu, on the web. On ChatGPT Pro, a custom MCP server connects for reading only, so ChatGPT can look things up in Conecto but not change anything.

### Does ChatGPT keep my business data?

Conecto keeps your records and the log of calls. What ChatGPT keeps from a conversation follows your ChatGPT plan's own data settings.

### Who hosts it?

Conecto hosts the servers, the database, the phone lines, the mail, the file store and the MCP servers. Your agent only needs the address.
