How document status updates work in 1C:Drive
Question: I have posted a payment for a Sales invoice. The document posted correctly but the list form is still showing the payment status is "Unpaid". What am I doing wrong?
Answer: If the payment document posted correctly, then everything is good. The status is still showing as "Unpaid" because of how 1C:Drive processes document status changes. Document statuses get updated by the background job "Update document statuses".

By default, this background job is scheduled to run every 5 minutes.

If the status of your document doesn't change throughout the day, check that the background job is properly scheduled for running every 5 minutes.
