4. Step-by-Step Procedure

Phase 1: Initiation and Data Retrieval

• Verify the purchase order (PO) or contract number associated with the service.
• Pull current client metadata (Legal entity name, Billing address, Tax ID) from the CRM.

Phase 2: Template Deployment

• Open the approved TR-Master-Invoice-v1.0 template.
• Populate the Header fields (Invoice #, Date, Due Date, Payment Terms).
• Input itemized line items including descriptions, unit pricing, and tax codes.

Phase 3: Validation and Quality Control

• Execute mathematical checksum: Verify Subtotal + Tax = Total.
• Verify that the "Remit To" banking information matches the current corporate treasury filing.
• Conduct a spell-check and branding compliance review.

Phase 4: Finalization and Distribution

• Save document as INV-[YYYYMMDD]-[ClientName].pdf.
• Attach generated invoice to the outgoing secure mail system.
• Update the ERP status to "Pending - Awaiting Payment."

5. Quality Assurance & Pro-Tips

• Data Integrity: Never use manual text boxes for totals; use cell-referenced formulas to prevent human calculation errors.
• Standardization: Use font Inter or Roboto at 10pt minimum for all body text to maintain document OCR (Optical Character Recognition) readability.
• Pro-Tip: Always include a direct "Pay Now" link in the PDF metadata/footer to reduce the Days Sales Outstanding (DSO) by an average of 15%.
• Threshold: Any invoice exceeding $50,000 USD requires a secondary audit signature from the Finance Lead.

6. Frequently Asked Questions

Q: What should I do if the client requests an invoice format that deviates from the standard template?
A: Deviations are prohibited without written authorization from the Finance Lead. Direct the client to our standard formatting policy.

Q: Why is the template locked to PDF/A format?
A: PDF/A is the ISO-standardized version of PDF specialized for the long-term archiving of electronic documents, ensuring the invoice remains viewable and compliant for audit purposes.

Q: How do I handle tax calculation for international clients?
A: Do not apply manual tax rates. Select the "Jurisdiction" drop-down in the template, which is linked to our live tax nexus database.
