Once you've set up a petty cash or cash drawer account, you need to put money into it, and then record that money transfer in QuickBooks.
To do this task, you can:
Write a check
Use an ATM machine or debit card to get cash, then transfer the funds to your petty cash account in QuickBooks.
What if later on I need to increase or decrease the base amount in a cash drawer?
Record petty cash expenses or cash drawer pay-outs
