It's great to have you here in the Community, kleandetailsllc-. I'd love to show you the best ways to record your cash transactions and paper-signed invoices.

1. Go to + New, then select Sales Receipt.
2. From the Customer ▼ dropdown, choose a customer.
3. From the Select a product/service ▼ dropdown, select the product or service that you sold.
4. Fill out the other necessary fields in the sales receipt, then select Save.
