We don't want you to feel this inconvenience, @kuehl87. And I personally want to get this fixed for you.

There are no actual limits on the size of your company data file, but performance may be hindered if your network is not capable of handling large data files.

If you have a large file and performance is slower than what is needed, you can reduce the size of your company file.

Also, you'll need to make sure that your QuickBooks Desktop (QBDT) and the Database Server Manager on the host or server, are up to date. 

If the issue persists, you may need to optimize your server and workstations to help minimize the issue. For the detailed process, you may check it here: Resolve QuickBooks Desktop performance issues - Manage your computers.

On the other hand, we store and process your customer's information in our and our trusted partner’s data centers, which are secure and monitored by professional staff. 

You can also check out this article to know why your customers need to email the same CC information: QuickBooks PCI Service FAQs.

Keep in touch if you need any more assistance with this, or there's something else I can do for you. I've got your back. Have a good day and stay safe.
