Questions, answered
Will it send payment reminders to customers?
No. WebRun only reads your Fortnox invoice list and builds an internal report. It never emails a customer, issues a reminder, or adds a late fee. Chasing stays your decision.
Does it change anything in Fortnox?
No. The run is read-only in Fortnox. No invoice is edited, credited, marked paid, or deleted. Everything written goes into your own Google Sheets workbook.
What if a customer paid over the weekend?
That invoice drops out, because WebRun reads the live unpaid list every Monday rather than reusing last week's report.
