Why approval speed matters
Every hour a truck waits for an answer is an hour of downtime for the customer and an hour of lost productivity for the shop. A technician who finishes diagnosis and then waits for approval is on the clock but not producing billable work. Ratchet+Wrench describes technician productivity as hours worked divided by hours available. Time spent waiting for an answer counts as available but not worked, so slow approvals pull that number down. Faster approvals help both sides. See technician productivity.
Approval also protects the shop. Some states require it in specific forms. California's Bureau of Automotive Repair, in its Write It Right guidance, says all repairs must be authorized by the customer in written, oral or electronic form before work begins, and that the authorization must be recorded on the estimate. Even where no such rule applies, a recorded approval is the best defense against a disputed invoice.
Step 1: Get the diagnosis right first
An estimate is only as good as the diagnosis behind it. Before writing the estimate:
- Confirm the complaint with the driver or fleet contact.
- Find the cause, with measurements, codes or photos.
- Check the unit history for recent related work.
- Confirm part numbers using the VIN and the component itself.
If diagnosis itself will take time, get approval for diagnostic time first and say how it will be billed.
Step 2: One line per problem
Write each repair as its own line, not one lump sum. For each line show:
- The problem in plain words. "Left rear outer brake lining worn to the rivets" is better than "brakes".
- The cause or finding, with the measurement where there is one.
- The correction, what the shop will do.
- Labor hours and whether billed at actual time or a set time. See book time.
- Parts with price and whether new, used or rebuilt.
- Lead time for any special order part.
California's guidance says estimates and invoices should describe parts and labor so the customer can easily understand what was purchased, and gives "R&R" as an example of shorthand to avoid. Plain words help any customer approve faster. See how to write a repair line with the 3 Cs.
Step 3: Show the evidence
Fleet managers often approve from a desk miles away. Give them what they would see if they were standing next to the truck:
- A photo of the worn, broken or leaking part.
- The measurement against the limit, such as pushrod stroke or tread depth.
- The fault code and what it means.
- For inspection items, the standard the item failed. See inspection failure.
Evidence turns "trust me" into "see for yourself", which removes the main reason for delay.
Step 4: Sort by urgency
Group lines so the customer can decide quickly:
- Safety or out of service. Items that must be fixed before the vehicle runs. Under 49 CFR 396.7, a vehicle may not be operated in a condition likely to cause an accident or breakdown. See out-of-service criteria.
- Recommended now. Items that will fail soon or cost more later.
- Can wait. Items to watch or schedule at the next PM.
Customers approve urgent safety work quickly when it is clearly separated from optional work. Mixing them makes the whole estimate look padded.
Step 5: Price it clearly
- Show the subtotal for each line and a total.
- List fees separately, such as a service call fee, mileage charge or after-hours rate.
- State taxes if they apply.
- For fleet customers, show the agreed rates and any purchase order limit. See purchase order.
- State how long the estimate is valid, and what happens if the job grows.
Step 6: Send it where the approver is
Ask at intake who approves charges and how they want to receive estimates. Then:
- Send a link by text or email that opens on a phone.
- Let the customer approve or decline each line, not just the whole estimate.
- Follow with a phone call for large or urgent estimates.
- For fleets with a customer portal, put the estimate there too.
Step 7: Record the approval
A good approval record includes who approved, the date and time, how they approved (signature, text, email, portal or phone), which lines were approved and declined, and the total approved. California's guidance, for example, lists what oral and electronic authorization must include, such as the date, time, name of the person and the phone number or email used. Keep messages used to get approval with the job.
Step 8: Handle added work properly
Technicians often find more problems once work starts. Do not do the extra work and hope the customer agrees. Write a revised estimate showing the added parts and labor and the new total, send it, and get approval before starting. California requires this for additional repairs. It is good practice everywhere.
Step 9: Follow up on declined lines
Declined does not mean forgotten. Record declined items on the invoice and unit record, and remind the customer at the next visit. For safety items, document that the customer was told.
Common mistakes
- One lump-sum price with no detail.
- Technical shorthand the approver does not understand.
- No photos or measurements.
- Sending to the driver when the fleet manager approves.
- Starting work on a verbal "go ahead" with no record.
- Doing added work before getting a revised approval.
Example only
An illustrative estimate for a tractor at a fleet yard might have four lines: one safety line for a leaking brake chamber with a photo, one recommended line for a worn belt, one can-wait line for a small oil seep to watch, and a separate line for the service call fee. The fleet manager approves the first two lines from her phone and declines the third for now. The shop records the approval with the time and her name, completes the work and lists the declined item on the invoice. All details in this example are invented for illustration.
Measuring approval speed
Track the time from estimate sent to approval received, by customer and by approver. Long gaps point to the wrong contact, unclear estimates or estimates sent at the wrong time of day. Track approval rates by line type as well. If recommended items are declined often, the evidence or the explanation may need work.
Estimates for mobile and roadside work
On a roadside call there is little time and the approver may be a dispatcher at a carrier office. Quote the call-out fee, mileage and labor rate before rolling, and confirm who can approve repairs. On site, send a short estimate with a photo as soon as the cause is clear. See how to quote emergency roadside repair.
Approval for fleet accounts
Fleet customers often have rules about who can approve and up to what amount. Ask for those rules when the account is opened and store them with the customer:
- The names and contacts of approvers.
- Any amount above which a second approval or a purchase order is needed.
- Work that is pre-approved, such as PM services or DOT inspection repairs under a set amount.
- Work that always needs a call, such as engine or transmission jobs.
Pre-approved work can move straight through, and the shop knows exactly when it must stop and ask. This removes most of the back-and-forth on routine jobs. See how to invoice fleet customers.
Owner-operators and walk-in customers
An owner-operator is usually the driver, the approver and the payer at once. The estimate still matters, because the customer is often deciding with limited cash and limited time. Show the safety items first, give a clear total, and say how long the repair will take. Ask for a card or deposit for large or special order parts before ordering. For new customers, a card hold before work starts is common practice in mobile work.
Checklist before you hit send
- Is every line in plain words?
- Is there a photo or measurement for each major item?
- Are safety items marked and separated?
- Are fees, taxes and lead times shown?
- Is it going to the person who approves?
- Can the customer approve each line from a phone?
