Yes, John. You can exclude the Product/Service column in QuickBooks Online (QBO). I know a way how you can achieve this.

In QBO, you can uncheck the Product/Service section within the Custom Form Style. Afterward, select the template you created for your invoice transaction.

Step 1: Turn off or untick the Product/Service section

1. Navigate to the upper right corner and click on the Gear icon.
2. Choose the Custom form styles.
3. Click the New style dropdown, then choose Invoice.
4. Within the given field under the Design tab, enter the preferred name of your invoice template.
5. Go to the Content tab.
6. You'll see three sections containing a pencil icon on their upper right side.
7. Click the middle section.
8. Untick the Product/Service checkbox.
9. You can also Edit the Labels and Widths of your columns.
10. Once you've finished customizing the invoice form, click the Preview PDF or Done.

Step 2: Add the created template to your invoice entry.

1. Go to the +New icon, then press the Invoice option.
2. Click the Manage, then hit the Design dropdown.
3. From the Other templates, tick the template that you created earlier.
4. Click the Manage to close the window.
5. Choose your customer and fill out the necessary fields, such as the Product or service section.
6. Once done, click Print and Download, Save, or Review and Send.

You can also exclude the Product/Service column in the old invoice layout by checking out this article: Customize invoices, estimates, and sales receipts in QuickBooks Online.

After creating an invoice and having your customer pays it, you can now record invoice payments in QuickBooks Online so it balances your account.
