Diagnostic fee acknowledgment questions, answered

What is a diagnostic fee acknowledgment?

A short form the customer signs before the technician starts diagnosing. It states the fee, what the fee pays for, whether it is credited toward a repair, and that the repair itself is priced and approved separately. It turns the fee from a surprise on the invoice into something agreed at the door.

When should the customer sign it?

After the technician arrives and before any diagnostic work begins. If the fee was already given on the phone or in the booking text, the form puts the same number in writing next to a signature.

What should the form say about the fee being credited?

Whatever your shop actually does. Some shops credit the full fee when the customer approves the recommended repair the same day, and some credit part of it or none. This form has a line for the credit term so the customer reads the same rule you apply on the invoice.

Does the signed form authorize the repair?

No. It covers the diagnosis only. The form says the repair is quoted after the diagnosis and needs its own approval before work starts.

Does this form satisfy my state's rules on service fees?

No form can promise that. Rules on disclosing service call and diagnostic fees vary by state and sometimes by license type. Use this as a record of what you told the customer, and check with your state licensing agency or a local attorney for what your state requires.

Do I need an account to use this form?

No. Download the blank form and print it, or fill in the visit details online and download a PDF. Neither needs an account.
