Hi all how can i customize payment voucher?

Hello, @cicriswan. I appreciate you checking this feature with QuickBooks Online (QBO).

There isn't a functionality in QuickBooks Online to customise a payment voucher. I understand how the feature you're looking for would benefit and boost your business needs. It could help add or remove any details that can be essential on the payment voucher form. In the meantime, I recommend sending this request directly to our product engineers via feedback. It helps us enhance program features such as customising payment vouchers.

Here's how to send a feature feedback:

1. Go to the Gear icon at the top.
2. Select Feedback.
3. Enter your comments or product suggestions. 
4. Then select Next to submit feedback.

I've added some articles you can check for your guidance about personalising forms in QBO, like adding fields and logos: 

• Add, customise, or remove logos on sales forms
• Customise Forms

Feel free to reply if you have other specific feature queries about QBO. I'm always here to help you out more. Stay safe and well.
