1. Executive Summary & Purpose

This SOP establishes the standardized workflow for generating, verifying, and distributing invoices for professional interpreting services. The objective is to ensure 100% financial accuracy, regulatory compliance, and rapid accounts receivable (AR) processing by minimizing billing discrepancies.

2. Scope & Prerequisites

• Scope: Applies to all freelance and contract interpreters operating under the Template Registry billing framework.
• Software Requirements:
  • Template Registry Billing Portal or approved PDF-generation engine.
  • Unified Assignment ID (UAID) tracking database.
  • Secure Cloud Storage (e.g., Encrypted Drive/S3 Bucket).
• Prerequisites: Completed assignment verification logs, signed time-sheets, and verified tax identification credentials.

3. Roles & Responsibilities (RACI)

4. Step-by-Step Procedure

Phase I: Data Aggregation & Verification

• Retrieve UAID from the assignment log.
• Confirm billable hours against the service sign-off sheet.
• Verify applicable rate (e.g., hourly, half-day, full-day, or emergency premium).

Phase II: Invoice Generation

• Populate Invoice Template with:
  • Unique Invoice Number (Format: YYYYMMDD-INT-[ID]).
  • Interpreter Full Name & Tax ID.
  • Detailed Service Description (Date, Time, Location/Remote Platform).
  • Breakdown of expenses (e.g., travel, parking, meal allowance) with attached receipts.
• Validate math (Subtotal + Applicable Taxes - Withholding = Total Due).

Phase III: Quality Assurance & Dispatch

• Perform a 3-point check (Name/ID match, Rate accuracy, Mathematical sum).
• Convert to PDF/A format to prevent unauthorized edits.
• Securely transmit to the accounts payable contact via encrypted channel.

5. Quality Assurance & Pro-Tips

• Metric Thresholds:
  • Billing Discrepancy Rate: Must remain < 0.5% of total invoices processed.
  • Turnaround Time: Invoices must be submitted within 48 hours of service completion.
• Pro-Tips:
  • The "Zero-Query" Rule: Include the assignment sign-off sheet as an attachment. Clients never dispute invoices they can immediately cross-reference.
  • Payment Terms: Always specify Net-15 or Net-30 prominently at the top right of the invoice.

6. Frequently Asked Questions (FAQ)

Q: My client is disputing a travel fee. How should I proceed?
A: Refer to the pre-agreed Service Agreement. If the fee is within the scope defined, re-send the invoice with the specific clause highlighted in yellow. Do not issue a credit memo until a formal review is conducted by Billing.

Q: What is the procedure if I miss a billing cycle?
A: Flag the invoice as "LATE SUBMISSION" in the header. Do not combine late services with current month invoices to avoid tax reporting reconciliation errors.

Q: Why must I use the PDF/A format?
A: PDF/A is an archival standard that ensures the document remains legible and unalterable regardless of the software version used by the client's accounting department, maintaining audit integrity.
