Review Cadence: Biannual (Q2/Q4)

1. Executive Summary & Purpose

This procedure defines the institutional standard for transitioning a formal quote into an actionable invoice template. The purpose is to ensure financial integrity, audit-readiness, and brand consistency by establishing a rigid workflow for document generation within the Template Registry ecosystem.

2. Scope & Prerequisites

• Scope: Applies to all client-facing financial documentation generation.
• Software Requirements: Template Registry Core Suite (v4.2+), Adobe Acrobat Pro (for final PDF/A validation), ERP-integrated accounting software (e.g., NetSuite/Xero).
• Data Inputs: Approved Quote ID, valid Tax ID, line-item inventory sync, and client Purchase Order (PO) references.

3. Roles & Responsibilities (RACI Matrix)

4. Step-by-Step Procedure

Phase I: Validation & Extraction

• Verify the Quote status is "Approved" in the ERP system.
• Validate the client Tax ID against the Master Vendor/Client List.
• Confirm no line-item modifications have been made post-quote approval.

Phase II: Template Synthesis

• Select the sanctioned "Invoice_v4_Primary" template schema.
• Execute the data-merge script to map Quote fields to Invoice headers (PO #, Client Name, Billing Address).
• Map variable line items; ensure VAT/Sales Tax logic calculates at the line-item level, not aggregate.

Phase III: Quality Assurance & Finalization

• Perform a checksum on the total payable amount against the source Quote.
• Verify that the document includes mandatory legal disclosures (Terms of Service, Payment Terms).
• Generate PDF/A archive copy; append unique document hash for audit traceability.
• Trigger final distribution via Secure Client Portal.

5. Quality Assurance & Pro-Tips

• Metric Threshold: Total Invoice amount must equal the Quote amount within a ±$0.01 variance (rounding tolerance).
• Pro-Tip: Utilize dynamic field mapping (e.g., {{quote_id}}) to prevent manual data entry errors. Never manually edit a template; always update the source schema.
• Common Pitfall: Failing to carry over "Special Instructions" from the Quote to the Invoice notes field. Ensure the remarks_data_block is mapped correctly.

6. Frequently Asked Questions

Q: What if the client requests a modification after the invoice is generated?
A: Do not modify the existing invoice. Issue a "Credit Memo" and generate a new Invoice Template iteration linked to an updated, re-approved Quote.

Q: How do I handle multi-currency conversions?
A: The Template Registry engine uses the system-synced mid-market rate at the timestamp of Quote creation. If a conversion error occurs, revert to the "Manual Override" workflow per Financial SOP-092.
