Thank you for choosing QuickBooks, @Cardinal1. I'm here to provide the calculation of the Common Area Maintenance (CAM) and include it in your invoices in QuickBooks Online (QBO).
The Tenant CAM charge equals Tenant Rentable Square Footage (RSF) divided by the Gross Leasable Area (GLA) multiplied by the Annual CAM. That said, I recommend referring to an accountant for more guidance about CAM calculations.
To add the CAM charges to your invoices, we need to create a service item for this.
Here's how:
- Go to the Gear icon and select Products & services.
- Click New, then choose Service.
- In the Name field, enter the name of the service.
- Fill out the necessary details.
- Once done, click Save and close.
Then, add this service item when creating your invoices. Please refer to this article for more details: Manually add service fees to invoices in QuickBooks Online.
Additionally, you can refer to this article about personalizing your sales forms: Customize invoices, estimates, and sales receipts in QuickBooks Online.
Let us know if you have other concerns with your invoice in QBO. We're here to help you in any way we can.
