i am a nail technician, and would like help with working out what i spend
every month( on supplies e.g nails, nail polish , nail polish remover, fuel(
car) , etc etc ), then be able to have a total figure at the end where i
charge for a certain job, i.e french nails $30... by being able to work out
how much im spending a month, compared to how much im earning... i'll soon
realise whether or not im under charging myself

look forward to your response

kind regards
