1. Executive Summary & Purpose

This procedure defines the standardized generation, validation, and issuance of invoices for janitorial services. The purpose is to ensure fiscal accuracy, minimize DSO (Days Sales Outstanding), and maintain professional tax compliance.

2. Scope & Prerequisites

• Scope: Applies to all recurring commercial, industrial, and residential janitorial service contracts.
• Software Requirements: Template Registry-compliant accounting software (Xero/QuickBooks Online) or standardized PDF generator.
• Prerequisites: Completed Service Log (Site Arrival/Departure), Client Authorization of Work Order, and valid Tax ID/Service Agreement.

3. Roles & Responsibilities (RACI Matrix)

4. Step-by-Step Procedure

Phase 1: Data Aggregation & Validation

• Verify Service Logs against the Master Service Agreement (MSA).
• Calculate billable hours including shift differentials or emergency call-outs.
• Ensure all variable supplies (chemicals, paper products) are itemized at contract rates.

Phase 2: Template Execution

• Populate Invoice Header: Invoice #, Unique Service Date, and Remit-To details.
• Insert "Scope of Service" summary (e.g., "Deep Clean - Q3 Maintenance").
• Apply applicable regional sales tax (calculated by service location).
• Attach verifiable proof-of-service (timestamped site reports).

Phase 3: Issuance & Verification

• Execute internal "Double-Check" audit for billing anomalies (>10% variance from previous invoice).
• Transmit via encrypted client portal or formal email.
• Set automated reminders for T+15 and T+30 payment intervals.

5. Quality Assurance & Pro-Tips

• Metric Thresholds:
  • Accuracy: 99.5% billing precision required.
  • Latency: Invoices must be dispatched within 48 hours of service completion.
• Pro-Tips:
  • Standardize SKU Codes: Use a fixed library of SKUs (e.g., JAN-LAB-01 for standard labor) to prevent manual entry errors.
  • Payment Integration: Embed "Pay Now" links directly in digital PDFs to decrease payment friction by ~22%.
• Common Pitfalls: Failure to reconcile site-specific exclusions (e.g., restricted access areas) often leads to invoice disputes. Ensure exclusions are noted in the footer.

6. Frequently Asked Questions (FAQ)

Q: How should we handle disputes regarding "Missed Services"?
A: Immediately cross-reference the digital site check-in logs. If verified, issue a credit memo (CM) within 24 hours to preserve the client relationship, then adjust the next cycle's invoice.

Q: What is the standard protocol for recurring supply cost fluctuations?
A: Apply a "Market Adjustment Clause" (MAC) as defined in the initial contract. Do not arbitrarily adjust supply line items; ensure documentation of the wholesale cost increase is attached as an addendum.
