1. EXECUTIVE SUMMARY & PURPOSE

This Standard Operating Procedure (SOP) defines the institutional-grade engineering lifecycle for generating, validating, and issuing construction invoices within Template Registry ecosystems. The purpose of this protocol is to eliminate billing discrepancies, mitigate cash-flow latency, ensure compliance with American Institute of Architects (AIA) standards (e.g., G702/G703 frameworks), and maintain absolute data integrity across project management, accounting, and client-facing interfaces.

2. SCOPE & PREREQUISITES

2.1 Scope

This document applies to all Chief Estimators, Project Managers (PMs), Billing Specialists, and Financial Controllers operating within residential, commercial, and industrial construction projects managed by Template Registry or its subsidiaries.

2.2 Prerequisites & Toolchain

• ERP / Accounting Software: Sage 300 Construction and Real Estate, QuickBooks Enterprise Contractor, or Procore Financials.
• Template Infrastructure: Template Registry Master Construction Invoice Template (v4.2-AIA-Compliant).
• Documentation Suite: Approved Schedule of Values (SOV), signed change orders, Daily Field Reports (DFRs), and architect-certified Application for Payment.
• Hardware/Access: Encrypted workstation with multi-factor authentication (MFA) enabled for financial database access.

R = Responsible, A = Accountable, C = Consulted, I = Informed

4. STEP-BY-STEP PROCEDURE

Phase 1: Data Gathering & Period Reconciliation

• Establish the exact billing cycle cut-off date (typically the 25th of the current calendar month).
• Collect and cross-reference all approved Daily Field Reports (DFRs) against labor hours and equipment logs for the billing period.
• Audit material delivery tickets and supplier invoices to verify direct job costs and on-site inventory.
• Pull the approved baseline Schedule of Values (SOV) and verify that no unapproved line items are introduced.

Phase 2: Change Order & Retainage Verification

• Compile all fully executed Construction Change Directives (CCDs) and Change Orders (COs) approved within the billing cycle.
• Ensure every active change order references the master contract number and includes sign-off from both the Owner and Architect.
• Calculate contractual retainage rates (standardized at 10% unless modified by specific municipal or private contract stipulations).
• Reconcile previous applications for payment to verify cumulative billed-to-date totals do not exceed contract caps.

Phase 3: Template Population & Mathematical Audit

• Open the standardized Template Registry Construction Invoice matrix (TR-CONST-INV-M4).
• Input project metadata: Project Name, Job Number, Contractor License ID, Client Entity, and Architect of Record.
• Populate the Line Item descriptions strictly mirroring the Master SOV format (Item Number, Description of Work, Scheduled Value, Work Completed from Previous Application, Work Completed This Period, Materials Presently Stored, Total Completed and Stored to Date, Percentage, Balance to Finish).
• Execute programmatic error checks to verify that: $$\text{Total Completed} = \text{Previous Work} + \text{Current Work} + \text{Stored Materials}$$ $$\text{Balance to Finish} = \text{Scheduled Value} - \text{Total Completed}$$

Phase 4: Quality Control & Executive Sign-Off

• Attach supporting documentation packet:
  • Conditional/Unconditional Lien Waivers (matching the prior and current billing periods).
  • Architect-certified AIA G702/G703 continuation sheets (if applicable).
  • Photographic logs for stored materials claimed on-site.
• Route draft invoice to Project Manager for operational scope verification.
• Route draft invoice to Financial Controller for tax compliance, retainage validation, and ERP ledger posting.
• Secure final digital authorization signature from the Accountable party.

Phase 5: Issuance & Accounts Receivable Tracking

• Export finalized invoice packet as a read-only, digitally signed PDF (.pdf/A format).
• Transmit the invoice package via the designated project portal or secure corporate email to the Client Accounts Payable department.
• Log the invoice issuance date, net payment terms (e.g., Net 30), and tracking ID within the ERP receivables module.
• Trigger an automated calendar reminder for the Billing Specialist to initiate follow-up protocols 5 business days prior to the due date.

5. QUALITY ASSURANCE & PRO-TIPS

5.1 Best Practices

• Zero-Variance Policy: Never modify an active SOV line item description without a fully executed change order. Discrepancies between the field status and the invoice line items account for 78% of payment delays.
• Lien Waiver Synchronization: Always issue conditional lien waivers concurrently with the invoice submission to accelerate payment processing by institutional lenders.

5.2 Common Pitfalls to Avoid

• Orphaned Change Orders: Invoicing for change order work before the formal change order document is countersigned by the client.
• Retainage Miscalculation: Applying retainage to taxable material line items or reimbursables improperly exempt under state mechanics' lien statutes.

5.3 Metric Thresholds

• First-Pass Yield (FPY): $\ge 98%$ of invoices must pass client/architect audit without rejection or requested revision.
• Days Sales Outstanding (DSO): Must not exceed contract terms by more than $5$ business days (Target: $\le 35$ days aggregate).

6. FREQUENTLY ASKED QUESTIONS

Q1: What is the protocol if an architect rejects a line item on the Schedule of Values during payment application review?
A: Immediately isolate the disputed line item. Issue a revised partial invoice for the undisputed balance to maintain baseline cash flow, while the Project Manager schedules a joint site inspection with the architect within 48 hours to resolve the contested percentage-of-completion metric.

Q2: How are stored materials handled when calculating the current billing period total?
A: Stored materials must be itemized separately on the continuation sheet. They require physical verification via photographic evidence, a bill of sale, and proof of dedicated off-site or on-site bonded insurance storage before they can be factored into the current billing total.

Q3: Can sub-tier lien waivers be submitted after the primary construction invoice is sent?
A: No. Under Template Registry compliance frameworks, verified conditional lien waivers from all subcontractors and suppliers who performed work in the prior period must accompany the current invoice package. Submissions lacking these documents will be halted at Phase 4.
