Sign the Diagnostic Fee First. Then Let the Customer Pick the Estimate.
By Oleg Goriachev · Appliance repair business owner and Taskrol founder
The diagnostic fee argument is never about the money. It is about when you raised it. At the door it is a signature. After the diagnosis it is a fight.
I already wrote about putting that conversation at the start of the visit. This is the next step: once the machine is diagnosed, do not hand the customer one take-it-or-leave-it price. Let them pick.
Sign the fee before the panels come off
The technician opens Diagnostic authorization on the job. The customer sees the fee and the terms — including that the fee remains due whether or not a repair is approved — and signs before troubleshooting begins. That signature does not approve parts, labor, or the repair. It only acknowledges the diagnostic visit.
Why that moment matters is in how to reduce diagnostic fee disputes. The short version: if you explain the charge after you have already opened the appliance, you are negotiating a bill. If you explain it at the door, you are agreeing on the visit.
Then put more than one estimate on the job
After the diagnosis, the same job can carry up to three estimates. One with the pressure switch, one without — a hundred dollars apart, both sitting on the ticket. The customer opens a public link, picks the option they want, and signs it. One tap. Not a phone call, not a text thread, not "let me think about it and call you back" that never comes.
The option they sign stops being an estimate. It becomes the invoice for this job — approved, dated, and signed. The option they turned down stays on the job as Not selected. Months later you can still see what you actually offered, instead of reconstructing it from memory.
One job, one invoice
That is the whole sequence. Diagnostic fee agreed at the door. Repair options on the same record. The chosen option is the bill. Payment sits on that same invoice. Nothing to stitch together in the office at night.
The walkthrough above also has a transcript on the video guide page. The full workflow is on the diagnostic authorization feature page. There is also a free authorization template if you want the wording on paper. Taskrol provides a consent template and a documented workflow, not legal advice; your company may review the wording with a lawyer for the requirements of its state or jurisdiction.
