EconomicoKeep vendor invoices correct through plan replacements
The problem A vendor invoice covers both the old and new plans, or arrives again after the seller was corrected.
Record separate plan charges on a shared invoice. Invoice and line references are checked across linked replacements, ignoring letter case and extra spaces. A re-delivered invoice can be recognised after the seller record changes when the amount and currency match and the service periods overlap. Interim statements leave unbilled coverage open for replacement.
