I'd like to ask which one (while, when or in) is more appropriate in the following sentence:
While/when/in dealing with contractors, we sometimes have to perform services which are not mentioned in the contract, and in such cases it is important to arrange in advance the performance of work and the payment for services.
I'm not sure that there's any or much difference between these, KPLNO. At least nothing leaps to mind.

I agree but really you can use any they are all perfectly acceptable.
'while' is not appropriate in this sentence. It means 'at the same time as'. what is the activity which is going on at the same time as dealing with the contractors? The implication is that it is the contractors who are asking for more services than contracted for.
It would make sense if the sentence were:
While dealing with contractors, he also had to fit in and juggle appointments with tradesmen.
CONJUNCTION: 1. As long as; during the time that: It was lovely while it lasted. 2. At the same time that;
1 a: during the time that <take a nap while I'm out> b: as long as <while there's life there's hope>
As long as you deal/During the time that you deal with contractors, you sometimes have to perform services which are not mentioned in the contract, ...
Your example, David,
While dealing with contractors, he also had to fit in and juggle appointments with tradesmen.,
is not a generic/habitual/routine statement, which is what the original poster's was [I can never remember the letter order]. It is a situation specific example.
