A service contract is a promise to pay for certain repairs, and the promise is only as good as the terms that price it. Much of what you will actually pay at a shop is not the part. It is the labor line, and the labor language in the contract decides how much of that line the provider will pay.
Find the labor rate clause
Some contracts do not pay the shop's posted hourly rate. They pay up to a stated rate, which may be tied to a published industry guide, to a figure the administrator sets, or to the rate in the region where the car is serviced. Read the exact wording. Is there a cap? What is it measured against? Does it change by location? If the shop charges more than the cap, the difference is yours unless the contract says otherwise.
Ask how the hours are counted
Labor is billed as time, and that time usually comes from a repair guide that sets how long a job should take. Ask whether the contract uses the same guide the shop uses, and whether the administrator can reduce the hours. A shop may quote a job as one block of hours, while the contract may allow a different count. Compare the two before you authorize any work.
Diagnosis time is its own line
Before any repair starts, a shop often bills for finding the problem. Ask whether the contract pays for diagnostic time, whether it pays only when the repair itself is covered, and whether the diagnosis has to be approved in advance. If the answers are unclear, ask the shop to contact the administrator before it begins work, and keep a record of who approved what.
Shop choice can change the rate
Some contracts limit where you can take the car, or pay a different rate at an approved facility than at a shop you would otherwise choose. Read the shop-choice clause and ask the seller or administrator to name the rate that applies to the shop you would really use, not to a shop in a brochure.
Put the gap in writing
Ask the seller to write down, in plain words, the labor rate that applies, what happens to hours above the contract's count, and who pays any difference. Keep that page with the signed contract. A verbal answer is not a term, and it will not help you at the service counter.
How to use the tables on this site
Our tables show the published figures we have read from each company's own terms, and they are the place to find which providers print labor language at all. Use them to narrow the list, then read the clause itself. If you want to see the wording before you buy, the providers that publish a sample contract are listed on their own page, and the way we score each company is explained on our methodology page.
