Hello there, @Anonymous. I'm here to ensure you'll be able to fix the shared custom reports in QuickBooks Online (QBO).
In QBO, the changes made to a previously shared custom report do not automatically sync to the other users. Once a custom report is shared by selecting an option in the Share with field, you only give the user access to edit it. To allow other users to see changes, you can email a PDF or an Excel file of the report to them. For more details, please visit this article: Share custom reports.
The program also allows you to modify the details of your sales forms to show only the info you want your customer to see. For the detailed instructions, check out this article: Customize invoices, estimates, and sales receipts in QuickBooks Online.
I'm just around the corner to help if you have any other concerns managing your shared reports. Don't hesitate to leave a reply below. Have a good one and take care.
