Final Invoice
Itemized final billing showing retainage release, change order adjustments, and lien waiver cross‑references to support payment and accounting reconciliation.
A well-prepared close out package reduces payment disputes, prevents lien exposure, documents warranty start dates, and creates an auditable record for contract closeout and regulatory compliance, while supporting enforceability under ESIGN and UETA when executed electronically.
Projects rely on coordinated input from owners, general contractors, and specialty subcontractors to assemble the close out package before final acceptance.
Roles determine signature requirements, timing, and which supporting documents are mandatory for contract closeout and record retention.
Typically a corporate representative, owner signs final acceptance and holds responsibility for release of retained funds; they must verify deliverables, inspections, and requisite certificates before executing acceptance.
