Bookkeeping help(Please)

I am trying to organise the books for a construction business but am unsure how to log things like petty cash and how a stock take comes into it in preparation for end of year tax return

For petty cash, usually it is on the books at a set amount (the amount of petty cash) so periodically go do a count of it and there should be either cash or the expense receipts when the cash was used. Ensure that both groups sum up to your gl acct (else cash or receipts are missing) then record the expense for the receipts and replenish the cash.
the part of your question "how a stock take comes into it" I do not understand - can you say this in a different way?
