Hi,
I've attempted the solution that you've suggested.
There is no option in the Sales form content to toggle custom settings on. Instead, it shows like below
Custom fields
Go to Settings > Lists > Custom Fields to manage your custom fields.
When I add a custom field to the invoice in the Custom Fields Settings, it adds the field in the invoice header, and not as a new column in the line item.
I am testing Quickbook Online for my business. Your assistance would be highly appreciated. If I can't solve this issue, I might not be able to use Quickbook Online for my business.
Thank you.
