Should I charge a teardown fee if a customer backs out mid-build?
Short answer
Yes, bill actual labor hours already performed plus a documented restocking or return cost on any parts already ordered. You don't work for free because someone changed their mind after you already had the engine apart.
Work performed is work performed, regardless of outcome
If you've torn down an engine, pulled measurements, or started assembly and the customer decides to walk away, the labor hours already spent don't disappear. Bill them at your normal shop rate for the actual hours logged, the same as you would for a repair the customer decides not to complete after diagnosis.
This is exactly why your build agreement needs to state up front that labor already performed is billed and due regardless of whether the customer proceeds, cancellation is not the same as a refund.
Parts already ordered are a separate conversation
Special-order performance parts often carry restocking fees or aren't returnable at all once opened or installed. Pass the actual documented cost of that back to the customer rather than eating it or guessing at a number. Keep the supplier's restocking policy and invoice on hand so you can show the real cost, not an estimate you made up to feel justified.
If the part has already been installed, even partially, it's very likely not returnable at all. Make that risk explicit before you order anything the customer hasn't fully committed to.
Put the reassembly question in writing too
Decide and state whether you'll reassemble the vehicle to a drivable state as part of the teardown fee or whether that's separately billed. A customer walking away mid-teardown often assumes you'll just put it back together for free; that assumption needs to be corrected in writing before it becomes an argument at pickup.
Teardown fee example
| Teardown labor already performed | 9 hrs @ $110/hr = $990 |
|---|---|
| Injectors already special-ordered, non-returnable | $1,400 at cost |
| Reassembly to drivable state (customer requested) | 6 hrs @ $110/hr = $660 |
| Total due before release | $3,050 |
The math: Total due equals actual labor hours logged at your shop rate, plus actual documented cost of non-returnable or restocked parts, plus any requested reassembly labor.
Mid-build cancellation clause
CANCELLATION AFTER WORK HAS STARTED If the customer cancels this build after work has begun, the following applies: 1. All labor hours performed to date, at [rate]/hr, are due in full and are not refundable. 2. Any parts already ordered are subject to the supplier's actual restocking fee or, if non-returnable, are billed in full to the customer at cost. 3. Reassembly of the vehicle to a drivable or reassembled state, if requested, is billed separately at [rate]/hr and is not included in the teardown fee. 4. The vehicle will not be released until all fees under this section are paid in full.
Where owners get this wrong
- Not billing for teardown hours because 'nothing was actually finished.'
- Eating a non-returnable parts cost instead of passing the documented cost to the customer.
- Reassembling the vehicle for free without ever discussing whether that's included.
