I appreciate you raising your concern with us, Yuri. When your accountant adds you as a client in QuickBooks Online Accountant, they have the option to bill your subscription charges to themselves or directly to you. Let me clarify this a bit more.
QuickBooks Online requires one subscription per company. You can invite your accountant so they can access your company file.
If you don't have an existing subscription, your accountant can add you as their client and subscribe to a plan that meets your company's needs, such as payroll.
During the client setup process, your accountant can either pay for your subscription costs themselves or choose for you to pay them. Please see the attached screenshot for visual reference.

In this case, I recommend consulting your accountant to confirm if they pick the latter.
Additionally, I suggest contacting our live experts to check these charges further. They possess the necessary security protocols to access your account details, which is beyond the scope of what can be done here in the Community space.
Here's how you can do that:
- Hover to the Help icon, then choose the Search tab.
- Type in Contact Us in the search bar.
- Click Contact Us, and choose the Callback option.

Moreover, you can use our Lookup a Charge tool to review any subscription or service fees associated with your account.
For future reference, you can create a payroll summary report. It will provide detailed information on your employee's wages, taxes, deductions, and contributions.
Contacting your accountant and our live support team can help shed light on your concern. This approach will also allow you to delve deeper into your billing inquiries.
