Hi there, @SkyeAspen.
When adding a subtotal for multiple items, it will only sum up the amount for the items added before it. If you want the total amount for the previous subtotals, you have an option to add another subtotal line item. I'd be glad to guide you how.
First, let's create a new item for the Total, and we'll use the Subtotal item type.
Here's how:
- Go to the Lists menu.
- Select Item List.
- Click the Item drop-down arrow and select New.
- Select Subtotal from the Type drop-down menu.
- In the Item Name/Number field, type in "TOTAL."
- Click OK.
Then, you can add this item to your invoices to show the total amount. See the screenshot below.
Additionally, you can check this article to see common FAQs about managing your items: Add, edit, and delete items.
Let me know if you have other concerns. I'll be around to help. Stay safe.
