i tell customers the price before i turnup... with out fail, however some customers think because i've only been there 20 mins they only have to pay a much smaller amount...

i have seen that (and also read one of the comments on this post) some companies charge a fixed rate - no matter how long it takes to diagnose faults, this i believe is a good idea as the customer knows where they stand, but what would be a "going rate"?

currently i charge £58 retail to come out and spend up to an hour,if more time is needed then the customer is informed and an hourly rate agreed (or a budget to work to)

as i've said, this has mixed reactions,

i've thought about pricing depending on what vehicle it is and what tool i have to use on it ie.. BMW - MERC - JLR £65 Ford, Vaux £45 for example.. does anyone else do this? if so how successful do you find it?
