Hi, CharmCr.
I can see how important it is to check how many times your client has viewed the invoices.
Though, we're unable to do this in QuickBooks Online. So, I recommend sending feedback to our product developers to add your vote about this feature and to help us improve our services. Here's how:
- Go to the Gear icon and click Feedback.
- Provide your feedback or product suggestions.
- Click Next to submit.
You can refer to these links if you want to enter customer payments or personalize the sales forms:
Let us know if you have further questions about managing your invoices. I'll be glad to help you. Have a good one.
