1. Executive Summary & Purpose

This Standard Operating Procedure (SOP) defines the institutional requirements, structural design, and verification workflow for generating, submitting, and reconciling locum General Practitioner (GP) invoices. The objective is to eliminate payment delays, ensure strict regulatory and tax compliance (HMRC/IR35 guidelines), and maintain immaculate financial audit trails for clinical sessions delivered across primary care networks (PCNs), NHS Trusts, and private practices.

4. Step-by-Step Procedure

Phase 1: Data Aggregation & Session Validation

• Retrieve all signed session logs, electronic rota printouts, and out-of-hours (OOH) Triage metrics for the billing period.
• Cross-reference session start/end times against the master booking confirmation to reconcile punctuality and un-rostered overruns.
• Confirm mileage, home visits, and administrative add-ons against agreed-upon contractual caps and rates.

Phase 2: Invoice Assembly & Template Initialization

• Initialize the Template Registry Locum Invoice Master v2.1.
• Input Locum GP legal entity details, registered business address, GMC number, and VAT registration number (if applicable).
• Input Client Practice details, including billing department address, Practice ODS code, and specific PO (Purchase Order) number if mandated by the CCG/Trust.
• Assign a sequential, unique Invoice Identifier (e.g., LGP-2023-10-001).

Phase 3: Financial Line-Item Itemization

• Itemize standard sessions (e.g., 4-hour morning session) detailing date, session type (Surgery, Triage, Administration), hourly rate, and total sum.
• Itemize extended hours, enhanced access shifts, or specialized clinics under separate designated line items.
• Document deductible expenses (e.g., home visit mileage calculated at approved HMRC rates) with explicit statutory justification.
• Calculate gross subtotal, apply VAT where legally mandated, and state the exact net payable balance.

Phase 4: Compliance & Payment Routing Verification

• Append mandatory statutory disclosures: Professional Indemnity cover statement and Limited Company registration details (if applicable).
• Verify BACS payment routing information (Sort Code, Account Number, Bank Name, and Remittance Email Address).
• Export the finalized ledger as a read-only, digitally signed PDF/A document.

Phase 5: Submission & Tracking

• Transmit the invoice securely to the designated practice management inbox with read/delivery receipts enabled.
• Log the transaction in the Accounts Receivable (AR) ledger with a hard calendar flag for the Net-30 payment due date.

5. Quality Assurance & Pro-Tips

Best Practices

• Immediate Logging: Transmit invoices within 24 hours of session completion to integrate smoothly into the practice’s monthly BACS payment run.
• Nomenclature Rigor: Name files strictly using the format: YYYY-MM-DD_Invoice_[InvoiceNumber]_[LocumName].pdf.
• PO Enforcement: Never execute a locum shift without securing a valid Purchase Order number if servicing an NHS Trust or corporate health group.

Common Pitfalls

• Vague Descriptions: Avoid listing generalized terms like "Medical Services." Itemize by specific clinical codes (e.g., "General Practice Consultations - 12 Patients/Hour").
• Missing ODS Codes: Omission of the Practice's Organization Data Service (ODS) code frequently halts accounts payable processing.

Metric Thresholds

• Payment Cycle Time: Target $< 14$ calendar days from submission to settlement.
• Rejection Rate: Target $0%$ billing rejection rate due to administrative errors.

6. Frequently Asked Questions (FAQ)

Q1: How should mileage and travel expenses be itemized on the invoice?
A: Travel expenses must be listed on a separate line item specifying the vehicle engine type, total business miles driven, and the current HMRC-approved advisory fuel rate. Attach scanned parking receipts as supporting documentation within the same PDF payload.

Q2: What is the mandatory protocol if an invoice passes the payment due date without settlement?
A: Issue an automated Statement of Account on Day 31. If unpaid by Day 45, invoke the Late Payment of Commercial Debts (Interest) Act 1998, levying statutory interest and appropriate debt recovery costs as outlined in your terms of engagement.
