Strategies on back charges from customer

I was wondering what process any of you are using to handle back charges on an order. Being an industrial equipment supplier, if a customer needs something fixed on site and it’s our fault, they can charge us back.

My initial thought is to use the RMA process and just make a dummy non-quantity bearing part number for back-charges. I’m thinking that it should flow through financials correctly and we could tie it to a case for case management. We just might have to make a modified report that changes RMA to BCA for Back Charge Authorization or something like that so the customer isn’t confused.

Any other strategies to handle this in play?

Thanks,
Brandon
