In short

How do I keep track of open sevDesk invoices every week?

WebRun checks sevDesk every Monday for invoices still open past their due date, holds a calendar follow up reminder for the most overdue customers, and messages you a WhatsApp digest with the total open balance and who owes the most. Paid invoices drop off automatically, so the digest always reflects what's genuinely still outstanding.

  • The full open balance is visible every Monday on WhatsApp
  • The most overdue customer always gets a calendar follow up
  • Paid invoices clear themselves from the digest automatically

Questions, answered

Will it message my customers directly?

No. The WhatsApp digest and calendar reminder are for you only. Contacting a customer about payment is still something you do yourself.

What counts as open?

Any invoice in sevDesk not yet marked paid and past its due date, read from live status each Monday.

What happens once an invoice is paid?

It drops off the digest and the calendar reminder clears on the next run.
