Connect FreshBooks to Claude Code

Have Claude draft invoices, log expenses, and chase payments in FreshBooks. From the terminal, inside the sessions where you already work.

How do you connect FreshBooks to Claude Code?

Claude Code reaches outside tools through MCP servers. To connect FreshBooks, you add a FreshBooks MCP server: a small hosted service that exposes FreshBooks's data and actions over the Model Context Protocol. With a custom connector we build for you, that is one command in the terminal, then an OAuth sign-in with your own FreshBooks account. No API keys pasted into config files.

claude mcp add --transport http freshbooks https://your-connector-url/mcp

Then run /mcp inside a Claude Code session to sign in. Add it with --scope project and the connector is checked into the repo for your whole team.

What can Claude Code do in FreshBooks once connected?

Full read-write FreshBooks access lets Claude draft an invoice from a client and line items, log an expense against a project, record billable time, and queue a payment reminder, then send once you approve. The invoicing and bookkeeping that used to mean manual entry happen where your accounting already lives.

  • Draft an invoice for a client with line items, taxes, and due dates
  • Log an expense and categorize it against the right client or project
  • Record billable time entries against a project or task
  • Create or update a client record and its contact details
  • Queue a payment reminder for an overdue invoice, sent after you approve
  • Convert an accepted estimate into a draft invoice

One connector, every Claude surface

The connector we build is a remote MCP server, which is the same standard claude.ai and Claude Desktop use. Add it once and the same FreshBooks access works in Claude Code for you, in claude.ai for the rest of the team, and in Claude Desktop. One build, one set of permissions, one monthly plan covering all of them.

Build it yourself, or have it built?

If you live in the terminal, you can absolutely write your own MCP server against the FreshBooks API. The protocol is open. What you take on is everything around the happy path: OAuth token refresh, hosting, monitoring, keeping up when FreshBooks changes its API and when the MCP spec itself moves, and scoping write actions so an agent can never do more than you intended. We build FreshBooks connectors with separated read and write tools and approval gates on destructive actions, then host and maintain them so they keep working while you work.

Frequently asked questions

Does the same FreshBooks connector work in claude.ai and Claude Code?
Yes. It is one remote MCP server. Claude Code adds it with a single "claude mcp add" command; claude.ai and Claude Desktop add it as a custom connector in Settings. Each person signs in with their own FreshBooks account, so access always matches what that person can already see and do.
Do I need to host or maintain anything myself?
No. The connector runs as a hosted service we operate: we handle uptime, token health, API changes on FreshBooks's side, and MCP spec migrations under the monthly plan. Your side is one command in the terminal and an OAuth sign-in.
Is it safe to give a coding agent write access to FreshBooks?
Write access is scoped, not blanket. Read tools and write tools are separated, destructive actions like deleting or sending are gated behind your explicit approval, and the connector can never exceed the permissions of the FreshBooks account it signs in with. Revoking access is one click in FreshBooks.
