When you pay cash or cheques into your company bank account, this is classed as a bank deposit and you should enter this in the Crunch app to ensure your banking records are up to date. From the 'Banking' tab you can select 'New bank deposit' to do this. If you are recording any cheque deposits, you'll be able to select them from a list of cheques you've entered as 'client payments received'.
Bank deposits can also include money lent to the company by its directors in the form of electronic transfer from a personal bank account, cash or cheque.
