# Your FreshBooks. Billed on time.

Source: https://corespeed.io/integrations/freshbooks

Connect FreshBooks to Claude Code, Codex, Cursor or any MCP agent through CoreSpeed. Your agent reads your clients, invoices, expenses, projects and tracked time, and tells you which hours are not billed yet. It uses your own FreshBooks login. Creating an invoice or recording a payment is a separate call that approvals can hold for a person.

## Set up an agent

Give your agent this line: `set up https://corespeed.io/SKILL.md (read it raw, e.g. with curl)`

It fetches the skill at https://corespeed.io/SKILL.md, adds the CoreSpeed MCP server, signs you in (or up), and keeps the skill for next time. Connect FreshBooks after setup. Access follows the connected account and its permissions. Create an account: https://app.corespeed.io/sign-up

## Find the hours. Then write the invoice

Let your agent match tracked time to clients and projects, and show what has not been billed before the month closes.

You ask your agent: "In FreshBooks, find the time entries for Harbor & Pine that are not billed yet. Total them by project. Do not create an invoice."

It calls CoreSpeed:

- `freshbooks__list_clients`: ok, 341 ms
- `freshbooks__list_time_entries`: ok, 466 ms

It reads from: FreshBooks.

### Unbilled time: 12.5 hours to invoice.

Harbor & Pine has 12.5 unbilled hours on the website refresh. At $150 an hour, that is $1,875.

**Website refresh**

- Design review, 3.0 h.
- Page build, 6.5 h.
- Client call, 3.0 h.

**Next**

- Create the invoice when you are ready. It is a separate call.

## Keep your agent. Bring your work

One CoreSpeed account, across compatible agents.

1. **Set up CoreSpeed**: Give your agent the setup line. It adds CoreSpeed and signs you in.

## Questions

### Can my agent create invoices in FreshBooks?

Yes, when you ask. Creating an invoice, an expense or a payment is a separate tool call that approvals can hold for a person. How approvals work: https://corespeed.io/docs/approvals

### Can it log time for me?

Yes. Your agent can log a time entry or start a timer, and edit or delete an entry. Each is a separate call.

### Do I have to switch agents?

No. CoreSpeed adds tools to the agent you already use: Claude Code, Codex, Cursor, or another MCP client. Each one signs in once.

### Can my agent access every account in our organization?

No. Access follows your CoreSpeed identity, each connection's visibility, and the app's own permissions. Personal connections stay private.

### Does this work without connecting an account?

No. Connect the app's account first; your CoreSpeed workspace shows what each app needs. The examples on this page use fictional data. All connectors: https://corespeed.io/docs/connectors
