The best construction AP automation software captures every invoice, matches it to the PO and receipt, routes approvals by job and holds payment until lien waivers are in. AvidXchange, Stampli, Ottimate and Medius document 3-way matching; AvidXchange, Adaptive and Stampli document waiver or document holds. Buildalytic adds delivery-receipt matching, AIA pay apps and posting to Vista, CMiC or Sage.
What to take away
- Ask every vendor to match one real invoice against its PO and the signed delivery ticket.
- Construction AP needs payment holds tied to lien waivers and compliance documents.
- Confirm the ERP connection for the system you actually run.

Why construction AP is different
A construction invoice is often a pay application with retainage, stored materials and change orders, and paying it without a conditional lien waiver can expose the owner to a lien. General AP tools match invoices to POs; construction AP also has to check the schedule of values, the waiver and the subcontractor's compliance documents before money moves.
Test with one ugly invoice
Pick a supplier invoice with a short delivery, a sub pay application with stored materials and a missing waiver, and an invoice that duplicates last month's. Ask each finalist to catch all three and show where the approval and hold happen.
