Drafting and Approving Invoices with the MCP Server

Use `create_draft_invoice` to build a new invoice in Wave, specifying the target customer ID and an array of line items. This lets you draft the paperwork without committing it to final accounting status. You can finalize that draft later by calling `approve_draft_invoice`. That moves the invoice into an unpaid or saved status within Wave Accounting.

Managing Customer Records in Claude Desktop

`create_accounting_customer` builds a new customer record right inside Wave. You just need to provide their name and email address, and it gets added to the system. If you run into trouble with an existing account, `get_customer_details` fetches all the specific data you need about that customer from Wave Accounting.

Reviewing Transaction History on Claude Desktop

`list_accounting_customers` pulls a complete list of every business client registered in your Wave Accounting account. It's perfect for checking who needs an invoice next. For invoices, `list_accounting_invoices` gives you visibility into all the bills issued by the business, helping you track payments and drafts.
