Shop trying to charge me more labor after I've paid the invoice?

Read what you post. There is nothing that you posted that says a paid invoice, receipt, or whatever you want to call it, is not a contract. All that is saying is simply sending an invoice is not a contract. Once it's paid both parties agree thus making it a contract.

 

I wasn't sure if T/A did that. If this were an auto repair shop instead of a T/A my first thought would be that the mechanic seriously overran the book time and the shop is trying to get the op to cover the loss.

 

Don't be making things up now when got cornered. Invoice is nothing but a prompt to pay. I prompt you to pay, you pay me. Then I reflect on the invoice error and prompt you to pay more, per agreed contract. You pay me because you agreed to pay me for all the services rendered, not - as in this case, for the services that I did not forget about at the time of the invoice. Time may be a factor...but in this case it is not. The point is that the invoice does not matter. What matters is whether all what they did per their mutual agreement was paid for.

 

Well by law they have to give you an estimate and run-down of what they plan to do if it is over a certain amount, don't they? If they exceed this, they need approval, don't they? I know in Florida, if a mechanic works on your car, by law he has to give you an estimate before commencing if it is above a certain amount. I forget what the amount is.

 

I think it'd help give our opinions if, we knew what work was done and how long it took. Not many of us LIKE to go to the TA for things, things like brakes and stuff like that I can do on my own, those aren't emergency repairs, those are planned maintenance items. We know they charge roughly $125/$150 per hour or whatever, so OP says they already itemized his bill...$966 worth of labor... so, maybe say 5 hours of labor. TA is calling him and saying hey we forgot to charge you for 3.5-4 hours of labor. So, what was done at TA for almost $1700 worth of labor alone?

Dont the mechanics punch in and out of jobs? Was the OP present when his truck was being worked on? I think id know if they worked on my truck for 12 hours......

Since TA is saying its labor costs, that means its time working on the truck. The OP has to ask himself, how long did they work on his truck, was it over 1/2 a day or 5-6 hours?

 

Of this we agree. And what was mutually agreed on was paid in full. Then TA is trying to say "you owe us more than we agreed on"
If any random roadside machanic did that you would not be calling him a cheat?

Simple fact is the work was done at the price quoted and agreed to. For TA to come back after the fact and ask for more is at best unethical, at worst fraud.

 

Doesn't matter. All that matters is TA agreed to the job at x amount the op paid. It's not the op's problem if TA under bid on the job.

 

Oh no, legally speaking I agree

Morally speaking, id pay it if they worked on my truck for 12 hours and I only paid 5

 

An invoice is a record of work done, it is part of the contractional agreement for the work done.

when the invoice is paid, it is considered as a conclusion of the contract for the work that was done >>>> an acceptance of the work done at the given consideration (money),

Any addition to the contract once that invoice is paid is outside the scope of the contract and can’t be recovered at this point.

For a contract to be legal - written or verbal (legal in the state of Michigan) - there has to be four general elements and a conclusion of the contract.

screw this idea that there is an ethical issue with the OP, it is on T/A site management to fix the issue by paying their people, not try to collect from a customer for their mistake.

In a few states this is actually illegal, once the bill is paid, it is done, going back to try to collect on other charges is fraud.

 

Morally speaking TA agreed on a price. They should stick to that price. It's not my problem they didn't quote the price correctly.

(I'm assuming, of course, the work order, estimate, or whatever was the same as the paid invoice. I.E. the agreed on amount.) Now if the work order quoted the extra $700 dollars then everything I've said is wrong being based on false assumptions and he should pay the rest of the bill.

It's absolutely no different than getting a brokered load only to find out at delivery there is a $700 lumper fee. The fee isn't the problem as long as it's built into the rate agreed to... Same with the repair. Who knows if the op would have approved the repair if the extra $700 was known up front vs. taking it to another shop.
