For e-bike shops

The bike that comes in with 'it just cuts out' is the hardest ticket in the shop. It might be a loose connector at the display, a speed sensor magnet knocked out of line, a battery with a dead cell group, or a motor fault that needs the manufacturer's diagnostic tool plugged in and a log pulled. You cannot quote it at the counter. You have to put it on the stand, connect the laptop, read the error codes, and often ride it to reproduce the fault.

That diagnostic time is real labor, and it is the labor most often given away. A mechanic spends forty minutes finding a pinched cable, fixes it in five, and the ticket says five. Multiply that by a season of commuter e-bikes and cargo bikes and it is a meaningful share of your bench hours.

Then there is the paperwork. A Bosch, Shimano or Brose warranty claim wants a serial number, a fault code, a description, photos and proof of the steps you took. The bike then waits for the replacement motor or battery, sometimes for weeks, and the owner, who uses it to get to work, calls every few days.

The strongest thing an e-bike shop can do for itself is diagnose to a written standard. When every e-bike gets the same checks in the same order, two things happen. Mechanics stop skipping steps that seem obvious, which is where most comebacks come from. And the record of what was checked becomes the evidence a manufacturer wants before it approves a claim.

Service checklists are built for that today. A diagnostic template can hold short answers for serials and error codes, numbers for battery voltage, dropdowns for the drive system, checkboxes for each connector inspected, photos of the burn mark on a connector or the damaged cable, and a signature from the owner accepting the diagnostic fee. Required answers keep the template honest. The PDF gives you something to send the manufacturer and the owner, and the CSV report lets you see, over a season, which faults keep coming back on which systems.

Checklist templates are versioned, so when you add a question for a new motor platform, older submissions keep the answers they were given. Your diagnostic history stays readable even as the template changes.

Diagnostic time gets given away because nobody writes it down. In Service, the mechanic clocks in against the visit before the laptop goes on the bike, and clocks out when the fault is found. The hours sit against the job, in the work category, and a manager approves the week's timesheet, so the forty minutes are on record whether or not anyone remembers them on Friday.

Getting that time onto the bill is still a manual step. Hours do not flow into invoice lines yet, so you add the diagnostic as a line on the quote or the job at the rate you charge. The quote handles the conversation with the owner well: the diagnostic fee is one line, the likely repair is another, and the extras the owner may decline, like a new charger, go on as optional lines. When the owner says yes, mark the quote approved and convert it into a job, and the chosen lines carry across.

When every visit on the job is closed, and the required diagnostic checklist is submitted, one click bills the job as a numbered invoice with the discount and tax worked out. Sending it marks it sent; it does not email the owner yet, so hand it over or send it yourself, and record the payment when it arrives.

The Service plan includes equipment records with serials and service history. For an e-bike shop, that becomes a record per bike carrying frame, motor and battery serials, with every visit listed, so the second time a battery comes in you can see the first diagnostic without digging. A bench board will add statuses for bikes waiting on approval or on parts, and purchase orders will link the part on order to the bike waiting for it.

Job costing is planned too. It will compare labor and parts against what you charged, which is how you find out whether your flat diagnostic fee covers an average Bosch fault or not. None of the items in this section can be used today, and until bike records exist, a job is recorded against the customer's site and name, so serials belong in the diagnostic checklist.
