Triage three routes before approval
Create three separate queues. Route a supplier invoice addressed to the company but lacking a purchase order to no-PO AP. Route an employee-paid purchase to expenses for reimbursement review, and a corporate-card purchase to card reconciliation. KSeF officially issues, receives and stores structured invoices; it does not perform internal purchase approval. Recommended control: AP checks the KSeF number, buyer NIP, supplier, amount and route within one business day, then assigns an owner. For example, an unplanned PLN 2,400 repair goes to the facilities budget owner, while a personally paid PLN 180 taxi goes to travel expenses. The major risk is processing one document through AP and expenses or card reconciliation, creating supplier payment and employee reimbursement. Route status should be exclusive and searchable by KSeF number.
