Who is this for
Who is this for Finance teams and freelancers using Pennylane (French accounting platform) who want daily alerts for unpaid invoices that need follow-up. What it does This workflow runs daily at 9 AM, fetches all customer invoices from Pennylane, and identifies unpaid invoices past their deadline by 7 or more days. If overdue invoices are found, it sends a detailed Slack reminder with invoice number, amount, days overdue, and a direct link to the PDF. If no invoices are overdue, the workflow ends silently.
