QuickBooks Online makes it easy to use vouchers and standard checks for your financial transactions, while wallet checks are available for QuickBooks Desktop users, @Sales--Person.
Printing wallet checks is helpful, but since it’s not available in QBO, you can explore third-party apps that offer pre-printed checks. Many of these apps often integrate with QBO and provide customizable options for your business needs.
Here's how:
- Click the My integrations button.
- Hit the +Find integrations.

- Search for and choose an app you want to use.
