GP locum invoicing resources: from completed session to paid invoice

Reliable locum invoicing is a controlled process: confirm the work, record it once, issue a clear invoice, retain evidence, follow up consistently and reconcile the payment.

Read the practical guide

Feature overview

Use this hub to design an invoicing routine that works across several practices without losing completed sessions, duplicating invoice lines or forgetting overdue payments.

  • New GP locums creating their first invoice process.
  • Established locums replacing Word documents and spreadsheets.
  • Locums who need better visibility over unpaid work.

Workflow

A practical workflow for keeping records current.

  • Capture each completed session and agreed extras.
  • Check billing and pension context for the organisation.
  • Create, check and send the invoice.
  • Track reminders and reconcile the receipt.

Connected records

How this feature fits into the wider airGP workflow.

  • Connects session records to invoice PDFs.
  • Keeps organisation and recipient details reusable.
  • Shows invoice email and reminder history.
  • Carries income records into earnings and tax reporting.

Build an invoicing system, not just an invoice document

A polished PDF is only one output. The real system begins with the booking and ends when the receipt is matched. It should show which sessions were completed, what was agreed, which organisation owes the money, whether an invoice was sent, when it became due, what follow-up occurred and when payment arrived.

A Word template can produce a valid-looking invoice while leaving those controls scattered across a diary, spreadsheet, sent folder and bank account. That may be manageable for occasional work. As volume grows, a session-led workflow reduces retyping and makes omissions easier to find.

Before the session: capture terms you will need later

Record the practice's billing identity and accounts contact, not only the familiar surgery name. Confirm the date, expected hours or session scope, fixed or hourly fee, reimbursable travel or parking, cancellation terms, pension arrangement and any purchase-order requirement. A short written confirmation prevents an invoice query weeks later.

Organisation management in airGP keeps practice details available for future sessions and invoices. Pension context can be recorded as Form A and B, GP SOLO or No Pension where appropriate to the workflow. This does not decide the correct category; it keeps your chosen, verified arrangement visible.

  • Correct legal or billing name and address.
  • Accounts recipient and required references.
  • Rate, hours, duties and agreed extras.
  • Pension arrangement confirmed with the organisation.
  • Payment terms and cancellation position.

After the session: turn evidence into a clear invoice

Update the session if actual hours, fees or agreed expenses changed. Then create the invoice from the reviewed record. Give every invoice a unique reference, show each work date clearly, separate expenses from clinical fees and use a total that can be recalculated. Check the recipient, bank details and PDF before sending.

airGP can generate invoice records and PDFs from session data, download them or email them from the invoice workflow. Several relevant sessions for the same organisation can be grouped when that matches the practice arrangement. The connection saves re-entry; it does not remove your responsibility to confirm the final document.

Five-minute pre-send control

  • Match every invoice line to the calendar.
  • Confirm each rate against the booking evidence.
  • Check expenses were agreed and are not duplicated.
  • Open the final PDF and inspect names, totals and bank details.
  • Send to the intended recipient and retain the email record.

Track unpaid work without confusing income measures

Completed work, invoiced value and cash received are three different measures. A locum may have worked £8,000 in a month, invoiced £7,350 and received £6,200. Treating any one figure as the whole story hides sessions awaiting invoice or invoices awaiting payment.

Use invoice status and paid dates to make those gaps visible. airGP retains unpaid, paid and cancelled invoice history, supports email logs and payment reminders, and feeds connected records into earnings and tax reporting. Bank evidence remains the final check that money arrived.

Invoiced valueWhat have I billed?Find completed sessions not yet invoiced
Unpaid invoicesWhat is still owed?Check due dates, queries and reminder history
Cash receivedWhat reached the bank?Match references, partial payments and paid dates

Handle late payment calmly and consistently

When the due date passes, first confirm that the invoice reached the right person and contains everything required for approval. Send a short factual reminder with the invoice number, amount, session dates and due date, attaching the invoice again where useful. Ask for receipt or a payment date rather than assuming bad faith.

If the practice raises a genuine query, resolve it and record the outcome. If an invoice remains unpaid, move through a consistent escalation process and seek appropriate advice before formal recovery. airGP's reminder and email-log tools provide an administrative trail; they are not debt recovery or legal advice.

  • Reminder 1: polite confirmation after the due date.
  • Reminder 2: refer to the earlier message and request a firm payment date.
  • Escalation: contact the relevant manager or finance lead with the full record.
  • Formal action: consider professional advice, contract terms and proportionality.

Month-end and tax-year controls

Once a month, compare the calendar, session list, invoice register and bank receipts. Investigate missing sessions, duplicate lines, unexpected totals and stale unpaid invoices. Check expenses and mileage while receipts and journeys are still memorable, and retain documents that explain material items.

At quarter or year end, structured exports are more useful when the underlying records have already been reconciled. airGP connects sessions, earnings, expenses, mileage, pension information and property records with tax exports and supported quarterly MTD workflows. The software helps assemble the records; you or your adviser remain responsible for completeness and tax treatment.

Frequently asked questions

GP locum invoicing resources: from completed session to paid invoice FAQs

What must a GP locum invoice include?

Use your correct supplier details, the practice's billing details, a unique invoice number and date, clear session lines, agreed expenses, totals, payment terms and payment details. Company requirements depend on your circumstances.

Can I put several locum sessions on one invoice?

Yes, when the sessions belong to the same organisation and grouping matches its process. List every date and rate clearly and ensure no session appears on another invoice.

How often should a GP locum invoice?

Use the cadence agreed with each practice. Weekly or monthly batching can work, but create a routine that prevents completed sessions being forgotten and does not delay cash unnecessarily.

How should I number locum invoices?

Use a unique, sequential and durable convention, such as initials-year-number. Avoid reusing a cancelled number; retain the cancelled record and reason.

Can airGP email invoices and reminders?

Yes. airGP supports invoice emailing, invoice email logs and payment reminder emails. Review the recipient, document and timing before sending.

Is an invoice spreadsheet enough for tax records?

It may be one part of the evidence, but you also need accurate source records, expenses and mileage evidence where relevant, payment reconciliation and retained documents. Ask your accountant what your circumstances require.
