Automate your invoicing with your AI assistant
The job: issue invoices without opening the app or filling in forms. You dictate the invoice to your agent and it creates, calculates and sends it.
This works through the Frihet MCP server (or the REST API if you prefer code). Requires your agent connected.
Create an invoice
"Create an invoice for TechStart SL, 40 hours of consulting
at €75/hour, due March 1st"
Your agent calls create_invoice: it detects the client (or creates one), adds the line item, applies 21% VAT and calculates the total. It shows you the draft before saving.
Chain actions in one prompt
No need to go step by step. A single message can create and send:
"Invoice Acme SL €2,000 of consulting and email it to them"
The agent creates the invoice (create_invoice), generates the PDF and sends it (send_invoice) in sequence.
Recurring invoicing
"Create a monthly recurring invoice to Acme Corp for €500 of hosting"
And to manage them:
"List my active recurring invoices"
"Cancel the maintenance recurring invoice for ClientX"
Collect and follow up
"Mark invoice F-2026-050 as paid"
"Show me all overdue invoices sorted by amount"
To chase unpaid invoices there's a guided flow: ask "Follow up on overdue invoices" and the agent runs the overdue-followup prompt — it groups by client and drafts the collection messages.
What's behind it
