I'm here to provide some information about doing a deposit invoice, @LMR BUILDERS.
I recognize how relevant requesting payment of a deposit to your business is. Currently, this option is unavailable in QuickBooks Online.
At times, we roll out enhancements based on our customer's requests. That being said, I suggest sending a recommendation to our product developers. They'll review this idea and might consider updating it in the future.
Here's how:
Go to the Gear located at the top.
Under Profile, click Feedback.
Enter your recommendation and select Submit.
In the meantime, you'll want to send an invoice to your client. Then add a note to the Message on invoice field to let the customer know the amount you need from them upfront for the deposit.
I hope you will find the alternative essential. As always, add a comment below if you have any other questions about managing your deposit invoices in QuickBooks. I'm here to help always. Take care!
