Hi there, ajsmith.

Thanks for joining this thread and for letting us know your interest in having the option to add barcodes to your templates in QuickBooks Online (QBO).

Since I want to make sure your suggestions gets to our product developers, let me personally submit a  product enhancement to hopefully gain this functionality in the future.

Another easy way to share your feedback is to enter them through this link: QuickBooks Online Feature Requests.
