How do lien waivers affect the AP process for construction companies?

March 27, 2026

Lien waivers gate invoice approval — payment cannot release until the correct waiver type is collected, matched to the invoice, and stored for audit. Vergo's AP workflow ties lien waiver status directly to invoice approval queues, blocking payment on uncleared documents without manual follow-up. This keeps job-cost coding accurate and protects against downstream lien exposure.

The Compliance Context

Construction companies must manage lien waivers as part of the IRS accountable plan rules and internal control standards. Auditors expect thorough documentation, including lien waivers, to verify that reimbursed expenses are valid business costs. Failing to collect lien waivers can expose companies to mechanics' liens, which disrupt cash flow and create legal liabilities.

Risks of Non-Compliance

Best Practices

  1. Systematize lien waiver collection as part of the AP workflow.
  2. Automate reminders and follow-ups to get lien waivers promptly.
  3. Use digital signatures and cloud storage to streamline the process.
  4. Integrate lien waiver management with AP invoice approval.
  5. Audit trail all lien waiver activity for compliance documentation.
  6. Configure AP policies to block payments without valid lien waivers.
  7. Leverage construction-specific AP automation software like Vergo.
