I appreciate your efforts to follow the instructions provided, R_V. However, there is another way to record the 50% down payment using an invoice. I will guide you through the process.

Before we start, you need to create an estimate for the customer who will be making the partial payment. Once that is done, we can create the invoice. Here are the steps to create the invoice:

1. Click on +New.
2. Under the Customers section, select Invoice.
3. Choose the customer and the corresponding invoice.
4. Enter the amount received (which should be 50% of the total invoice).
5. Click Save and then close the invoice to record this partial payment.

Just a heads up, the deposit in the invoice allows you to record advance payments received from a customer before the completion of a job or delivery of products.

Additionally, we appreciate your interest in expanded functionalities and encourage you to submit your suggestions through feedback on your QuickBooks Online account. This will help our product development team assess potential additions for future updates.

Here's how you can send your feedback:

1. Navigate to the Gear menu and choose Feedback.
2. Enter your feature request in the description box.
3. Click on Next when you're finished.

Moreover, once the payment is complete, record it by navigating to the Receive Payment.
