Flag an Exported Invoice as Changed
When an invoice has already been exported to an accounting system and someone later changes it there, the two records no longer match. On an exported invoice, the Mark as Modified button lets you flag the invoice in ServiceVisit as modified in accounting so that the difference is visible to whoever reviews it.
A comment is required, up to 500 characters, describing what changed. ServiceVisit saves the comment together with who flagged the invoice and when. Only an invoice that has actually been exported can be flagged; asking for any other invoice is refused.
The flag is a record kept in ServiceVisit. It does not edit the invoice itself and does not send anything to the accounting system.
