Produce an accurate invoice, collect payment, and handle callbacks and warranty claims consistently and fairly.
- Applies to: Technicians and office
- Frequency: Every completed job; callbacks as they arise
- Scope: Defines invoicing, payment collection, and the callback/warranty process. Business workflow only; any re-diagnosis on a callback follows the field and deferral SOPs.
What you need
- Invoicing software
- Itemized parts/labor records
- Payment terminal/methods
- Warranty policy document
- Callback log
- Customer communication templates
The procedure, step by step
- Build the invoice — Itemize parts, labor, the diagnostic fee handling, taxes, and total, matching the authorized estimate.
- Review against authorization — Confirm the invoice reflects the approved work and explain any approved variances before billing.
- Collect payment — Collect payment per the agreed terms and provide a receipt and clear record.
- State the warranty — Tell the customer the parts/labor warranty terms in writing on the invoice.
- Log the job for warranty tracking — Record parts, serials, and dates so future callbacks can be checked against warranty.
- Handle callbacks promptly — For a callback, review the original work, re-diagnose per the field SOPs, and honor warranty terms where applicable.
- Resolve and document — Resolve the callback, document the cause and outcome, and use it to improve the process.

This is a free, source-anchored standard operating procedure (SOP) you can print and hand to staff. It documents the work sequence for a Appliance Repair business — not safety or regulatory rulings, which defer to the cited authorities, the applicable code, and your own health-and-safety plan. Open the tool above to print it, toggle ink-saver, or (with a free ToolFluency Business account) edit it to match your own workflow.

Frequently asked questions
What belongs on an appliance repair invoice?
Itemize parts, labor, how the diagnostic fee was applied, taxes, and the total, and confirm it matches the authorized estimate before billing. Stating warranty terms in writing and logging parts and serials lets you check future callbacks against the warranty fairly.
How should callbacks be handled?
Review the original work, re-diagnose per the field SOPs, and honor the stated warranty where it applies. If a callback surfaces a gas or sealed-refrigerant issue, that work defers to a licensed/EPA 608-certified technician under the manufacturer's service information.
