Yes that is the way I do it in Sage instants. Just post it as a Bank Payment, not sure of the nominal code as I don't use it that much and I haven't got it open at the mo to check.
Also, can you advise me on showing money deposited. I presume I go into the bank, but then not sure what to do from there. They are for payments into the bank using paying in slips.
Some are payments by cheque and some cash - does that make a difference? Also the cash account is at zero balance, if I take from there to the main bank account then the cash account will then be a negative figure- is this right?
Where did the cash come from? If it is, for example, a customer paying an invoice, then you would receipt that invoice to the cash account and then when you bank the cash, transfer it over from the cash account to the bank account.
