Welcome and thank you for posting here in the Community, @Triple S.
I'd be delighted to help create a receipt for your customers who pay with checks or cash.
In QuickBooks Online (QBO) you can create a sales receipt, this is used when the customer pays you on the spot for goods or services. To create a sales receipt:
- Go to the Plus (+) icon.
- Select Sales Receipt under Customers.
- Fill in the necessary information in the Sales Receipt page and save the transaction.
You may also need to create a petty cash account and deposit the money there.
