I say that you are free to charge whatever you think is right, just as they are free to take their business to any place they would like, based on whatever their decision making criteria is. If they want to do business with you, then they pay your price, if not then go elsewhere.

However, I suspect they want you doing the quality work that you do, BUT at your competitor's price. It doesn't work like that.

Stand your ground! But also be ready to lose the account.

If they asked you do the work (at your assumed prices) then wanted to pay you less, I wouldn't accept that. Tell them to pay your bill and then invite them to not come back.

Insurers don’t “take their business “ anywhere. The customer is the car owner, and if they have insurance they can assign their benefits to you. As Mark1 quoted from another regular on this site, “Who is the customer?” If you can’t answer correctly you need to find a different profession.

Freddy is correct on this one.

ESPECIALLY if it's an insurer, who did NOT contract for the repairs with you, contacting you to "alter" invoices you have already generated with YOUR customer. Just because you SHARE a common customer, does not give an insurer the right to become a third wheel in a two party contract of repair. Not until, or unless, the insurer CHOOSES to contract FOR the repairs within the insurer's stated rights or options under their policy of insurance.

Even then, IF they do, which no one knows of ever happening since the 1960s, they would have to do so BEFORE the repairs are completed, or a repair contract between you and the owner is created, not AFTER.

Of course, then the insurer would assume the liability of repairs, which is exactly why this does not happen.

But we've been through this many times, go back and research old strings and read up.
