Retainage
Built-in retainage fields permit automatic calculation and clear display of withheld amounts so approvals and payment runs can account for contract-specific retainage policies.
Using a standardized e invoice sample for construction industry reduces invoice processing time, improves accuracy of retainage and change-order handling, and creates verifiable audit records for payments and approvals when paired with a compliant eSignature solution like signNow.
Project managers review line-item progress billing, verify quantities against field reports, and approve invoices for payment. They coordinate change-order references and confirm supporting documents such as inspection certificates before routing for signature.
Billing administrators prepare e-invoice samples, populate contract terms and retainage, attach lien waivers, and manage payment routing. They maintain templates and ensure invoices meet owner and lender documentation requirements.
Construction accountants, project managers, and field supervisors use e-invoice samples to maintain consistent billing across job sites and contracts.
Adopting standardized e-invoice samples helps project teams reduce disputes, accelerate approvals, and maintain auditable records for owners and lenders.
Built-in retainage fields permit automatic calculation and clear display of withheld amounts so approvals and payment runs can account for contract-specific retainage policies.
Support detailed line items, unit quantities, unit pricing, and phased billing so progress invoices align with field reports and contract deliverables.
Attach approved change-order references and separate adjustments to show original contract amounts versus modifications for transparent reconciliation.
Require and attach conditional or unconditional lien waivers per invoice to support owner payment processes and reduce lien exposure.
Configure approval rules that require project manager sign-off for invoices exceeding thresholds or missing documentation to enforce internal controls.
Sync e-invoice data with accounting and ERP systems to automate posting, tax handling, and payment reconciliation, minimizing manual entries and errors.
Create and store invoice templates that pre-fill contract numbers, retainage rules, tax calculations, and standard line items to reduce repetitive entry and ensure consistent formatting across all subcontractor submissions.
Connect e-invoices to accounting systems like QuickBooks or Sage so billing records synchronize automatically, improving reconciliation accuracy and reducing duplicate data entry between invoicing and general ledger systems.
Use Bulk Send to distribute the same invoice template to multiple recipients for recurring charges or standardized submissions, enabling faster signature collection across several subcontractors or approvers simultaneously.

A general contractor consolidated subcontractor progress bills into a single e-invoice template to standardize line items and retainage references.
Resulting in accelerated payments, fewer disputes, and clearer audit records for owner approvals.
An electrical subcontractor used a tailored e invoice sample for construction industry that included lien waivers and inspection attachments on each submission.
Resulting in faster clearing of invoices, improved subcontractor cashflow, and a documented digital trail for the project file.
