Standard Operating Procedure

Registry ID: TR-INVOICE-

Standard Operating Procedure: Hourly Service Billing & Invoicing

Document ID	SOP-FIN-042	Effective Date	2023-10-27
Version	1.0.0	Review Cadence	Annual

1. Executive Summary & Purpose

This SOP establishes the standardized workflow for generating, verifying, and dispatching invoices based on logged hours. The objective is to minimize revenue leakage, ensure tax compliance, and maintain a high-velocity billing cycle by eliminating ambiguity in service hours rendered.

2. Scope & Prerequisites

Scope: Applies to all contractors and departments utilizing Template Registry billing modules for hourly-based compensation.
Prerequisites:
- Verified time-tracking data (Time-stamp audited).
- Approved project SOW (Statement of Work) or rate card.
- Access to enterprise invoicing software (e.g., QuickBooks, Xero, or internal ERP).
- PDF/A export capabilities for archival integrity.

4. Step-by-Step Procedure

Phase 1: Data Reconciliation

Aggregate raw time logs from verified tracking software.
Cross-reference logged hours against the approved SOW for scope creep.
Identify and justify any overage hours (requires PM sign-off).

Phase 2: Template Configuration

Select approved "Hourly Services" template (Template ID: TR-BILL-HR).
Input Company/Client Master Data (Legal entity names, tax IDs, physical addresses).
Populate line items: Description of work, Date range, Rate per hour, Total hours, and Subtotal.

Phase 3: Validation & Quality Control

Perform a sanity check on mathematical outputs (Automated vs. Manual).
Validate "Payment Terms" (e.g., Net 30) align with contract stipulations.
Attach supporting documentation (Timesheet CSV export) for high-value invoices.

Phase 4: Transmission & Archival

Execute formal sign-off by Project Manager.
Dispatch via secure channel (Encrypted email or client portal).
Save immutable copy in /Financials/Invoices/[Year]/[Client]/ directory.

5. Quality Assurance & Pro-Tips

Metric Threshold: Invoices must be dispatched within 48 hours of service period completion to ensure a 95% on-time payment conversion rate.
Pro-Tip 1: Use "Round-to-the-nearest-quarter-hour" increments. Standardizing granularity prevents fractional-cent disputes.
Pro-Tip 2: Always include a "Last Paid" date on the invoice to provide the client with immediate account visibility.
Pitfall: Avoid generic "Consulting Services" descriptions. Use specific, task-oriented descriptions to pass internal audits and reduce client queries.

6. Frequently Asked Questions

Q: What if the client disputes an hourly entry? A: Immediately flag the entry in the CRM. Provide the raw timestamp data for the disputed entry. Adjust the invoice only after a formal credit memo is processed; do not modify the original invoice post-dispatch.

Q: Are there requirements for multi-currency billing? A: Yes. Invoices must list both the native currency of the client and the functional currency of Template Registry, utilizing the exchange rate established on the invoice date.
