# Stripe, PayPal and Square in the books: Best Bookkeeping App

**Answer in brief:** Sales arrive through payment apps. Connect them to Claude next to Conecto, and the agent books each payout and matches it when it lands.


## Connect the payment app

Stripe's server at `https://mcp.stripe.com` signs in with OAuth or an agent API key.[1] PayPal's answers at `https://mcp.paypal.com`,[2] and Square's remote server at `https://mcp.squareup.com/mcp` reaches customers, orders and items.[3] Claude's Free plan allows one custom connector, so Conecto and a payment app together need a paid plan.[4]

## Book, then match

Ask the agent to read each payout and book the sales and the fees, then match the payout to the bank line when the money lands. Each match costs $0.02.[5]

## Invoices paid online

Invoices sent from Conecto can be paid online through Stripe, and invoices post to the books on their own.[6][5]
