Thank you for joining this conversation, @tbard.
I'm here to convert the same functionality for web based (QBO) subscriber.
You can utilize the Progress Invoicing feature to record the transactions in QBO. This allows you to split an estimate into as many invoices as you need.
Let's first turn on this feature:
After that, you can create a customize invoice template and name it as your "progress invoicing template".
Next, create an estimate that has the total amount of the product:
Lastly, you're all set to create a progress invoice from the estimate!
You can decide how much you want to invoice according to the estimate. You can charge for a percentage or a specific amount. If you choose Custom amount for each line, then you'll have to enter a specific amount for each item on the invoice.
That should get you going today. Let me know how it goes or if you have any follow-up question about progress invoicing. I'll be here if you need further assistance. Wishing you all the best!
