OOWV & Slack
Free up time otherwise spent on OOWV, then move it to Slack
GetMyInvoices takes over retrieval from OOWV and forwards the documents to Slack, so you no longer check the portal manually.


Why connect OOWV with Slack?
GetMyInvoices automatically retrieves your OOWV invoices and delivers them to Slack. It logs in to your OOWV account for you, fetches every new invoice as a PDF plus structured data, sorts and validates it, and exports it to Slack booking-ready. One connection covers every OOWV account and recurring billing period.
- Automatic retrieval to Slack: connect OOWV once, never log in for an invoice again.
- Booking-ready in Slack: the PDF plus the structured data your accounting needs.
- Built for many accounts: agencies, IT service providers and tax firms in one dashboard.

From OOWV to Slack automatically
Three things happen automatically once OOWV is connected, so your invoices reach Slack without manual work.
Retrieves every OOWV invoice
GetMyInvoices logs in to OOWV Cloud and Robot on a schedule and downloads each new invoice for you, including past invoices still available in your account.
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.
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.
