I am using Quickbooks Premier and have over 20 companies. I have not been able to attach files to transactions and am wondering if I need to set up the companies differently. I have tried different companies and they only set up one Attach file.
Thank you for bringing this to my attention, @Beatriz1.
Let me help share some troubleshooting steps to resolve your issue.
Since we don't have any reported investigation about attaching files to transactions, you can perform the following steps below to fix this:
Also, sharing the attachments across multiple company files is not possible. If you need to do that, you'll have to make a unique copy for each company file.
You can refer to this article for more information about attaching files: QuickBooks Document Center: FAQs and common issues.
Keep me posted on how the steps went. I'll be here to help get this working for you.
