Acquisitions are how the mid-market grows now: US private equity’s middle market recorded an estimated 4,018 deals in 2025, a record share of all PE buyouts. Behind a meaningful share of those transactions is the same finance team — five to fifteen people, no shared-services group, and a new entity to absorb.
Every acquisition creates a debt that never appears on the closing statement: separate invoice inboxes nobody consolidated, vendor masters holding the same suppliers under different names, approval matrices that contradict each other, two or more ERPs with one mid-migration. The standard plan — “we’ll fix AP when we consolidate ERPs” — is the expensive path, because ERP consolidation takes years and AP consolidation takes weeks. This paper is about running AP as one governed process above the entity structure.
