I appreciate you on joining the thread, @JustMeAt107. Allow me to share more information about the Security Metrics.

All companies that process, store, or transmit credit card information must maintain a secure environment by the PCI Security Standards Council. So, even if you're not one of the merchants if you're processing customer payments through QuickBooks, you'll have to comply with this.

Moreover, this is not mandatory if you use outside payment processors such as PayPal or Melio. That said, the choice is up to you.

Additionally, you can generate reports to get an overview of your business finances.

Let us know if you still have further questions about compliance. Take care.
