If you're referring to recording a payment, you can create an invoice to record the sale. Then, receive the payment to record it against that invoice.

Here's how:

1. Click the Plus icon (+) on the top menu.
2. Choose Invoice.
3. Complete the fields with necessary information.
4. Click Save and close.
5. Then, go to Receive Payment section by clicking the Plus icon (+) on the top menu.
6. Choose a customer, then select an invoice/s you want to close out.
7. Select the payment method and account where the payment will be deposited to.
8. Click Save and close.

If it is an immediate payment transaction, you can create a sales receipt. You can check out the Should I use an Invoice or a Sales Receipt? article. Then, follow the steps in  To create a Sales Receipt section
