Old open purchase orders are rarely difficult because there is one magical button nobody knows about.
First Classify the Problem
Was it received? Partially received? Invoiced? Backordered? Cancelled? Duplicated? Abandoned?
Work With the People Who Know the History
We like to sit with the client's strongest purchasing and accounting users because they know which vendor relationships, old practices, and historical transactions are real.
Establish the Correction Method
Once the system condition is understood, we determine the safe process for rebalancing or closing the affected POs.
Teach the Pattern
If dozens or hundreds of documents need the same controlled cleanup, we would rather teach trusted client users the repetitive part after the method is proven.
Consulting time should solve the system problem. The client's team can often handle repetitive execution once the rules are clear.
