One connection covers every km3 account and recurring billing period.

  • Automatic retrieval to Slack: connect km3 once, never log in for an invoice again.
  • Booking-ready in Slack: the PDF plus the structured data your accounting needs.

From km3 to Slack automatically

Three things happen automatically once km3 is connected, so your invoices reach Slack without manual work.

1

Retrieves every km3 invoice

GetMyInvoices logs in to km3 Cloud and Robot on a schedule and downloads each new invoice for you, including past invoices still available in your account.

2

Captures the data, not just the PDF

Each invoice is read, sorted and enriched with structured fields like invoice number, date, net, gross and VAT, then archived in a GoBD-compliant way.

3

Delivers your invoices to Slack

Invoices and their data are exported to Slack, ready for your tax advisor to book. No re-typing, no missing receipts.

Slack is the integration that receives your km3 invoices and receipts. GetMyInvoices downloads them automatically and hands them over ready to book — no manual downloading needed.
