Freshbooks
This connects Claude to FreshBooks so you can manage invoices, clients, expenses, and payments without leaving your workflow. It's built on Membrane, which means auth and credential refresh happen automatically. The skill covers the usual accounting operations: create and update invoices, track payments, manage clients and billable items. You get pre-built actions for common tasks, plus a proxy for direct API calls when you need something specific. Best for freelancers and small business owners who want their AI agent to handle bookkeeping tasks. The Membrane layer is nice because it keeps you from wrestling with OAuth tokens yourself.

Working with Freshbooks
This skill uses the Membrane CLI to interact with Freshbooks. Membrane handles authentication and credentials refresh automatically — so you can focus on the integration logic rather than auth plumbing.
Install the CLI
Install the Membrane CLI so you can run membrane from the terminal:
npm install -g @membranehq/cli@latest
Authentication
membrane login --tenant --clientName=<agentType>
This will either open a browser for authentication or print an authorization URL to the console, depending on whether interactive mode is available.
