1. Executive Summary & Purpose

This document establishes the technical protocol for generating labor-based invoices at Template Registry. The objective is to ensure standardized billing for professional services, mitigate revenue leakage, and maintain audit-ready documentation for all client-facing engagements.

2. Scope & Prerequisites

• Scope: Applies to all hourly, project-based, or retainer labor rendered by staff.
• Prerequisites:
  • Approved Master Service Agreement (MSA) or Statement of Work (SOW).
  • Verified Time-Tracking Logs (e.g., Harvest, Jira, or manual timesheets).
  • Access to Financial ERP (e.g., QuickBooks, Xero, or NetSuite).
  • Standard Template ID: TR-LBR-INV-CORE.

3. Roles & Responsibilities (RACI)

4. Step-by-Step Procedure

Phase I: Data Validation

• Cross-reference time logs against project SOW to verify task eligibility.
• Confirm all labor entries include specific timestamp, task description, and project code.
• Validate billable rate per the client’s executed contract.

Phase II: Template Configuration

• Instantiate TR-LBR-INV-CORE template.
• Insert unique Invoice ID (Format: YYYYMMDD-ProjectCode-XXX).
• Populate header with Entity Name, Tax ID, and Remittance Instructions.

Phase III: Line-Item Aggregation

• Group labor by phase or milestone as defined in the contract.
• Include detailed narrative for each line item (e.g., "Consulting: Architecture Review - 4.5 hrs @ $200/hr").
• Calculate subtotal, applicable taxes, and total balance due.

Phase IV: Quality Review & Dispatch

• Perform a 3-way match: (1) SOW/Contract, (2) Time Logs, (3) Draft Invoice.
• Attach PDF copy of time logs as supporting documentation for transparency.
• Finalize document to PDF/A format to ensure immutable record keeping.
• Dispatch via secure portal or encrypted email to the client's Accounts Payable department.

5. Quality Assurance & Pro-Tips

• Metric Thresholds: All labor invoices must be dispatched within 48 hours of milestone completion.
• Common Pitfalls:
  • Vague Descriptions: Avoid "Services Rendered." Use "Development of API Schema."
  • Rate Mismatch: Always verify rate adjustments post-contract renewal before generating the draft.
• Pro-Tip: Include a "Payment Terms" footer (e.g., Net-30) in bold red to reduce late payments by 15%.

6. Frequently Asked Questions

Q: What if the client disputes a specific hour count?
A: Flag the invoice as "Pending Review," notify the Account Manager immediately, and request a detailed audit of the time-tracking log associated with that specific date. Do not reissue the invoice until the dispute is resolved in writing.

Q: Are manual edits permitted on the standard template?
A: Minor formatting adjustments for branding are permitted. However, structural changes to the tax calculation logic or the inclusion of non-standard legal clauses are strictly prohibited without authorization from the Finance Department.
