Hi @Ssantana,

I appreciate you for reaching out to us here in the Community. Let me share some clarification about the order of the products or services when sending invoices.

Currently, a direct way to send invoices in your preferred order is unavailable. The system automatically filters the line items based on the service date.

As a workaround, you can download the invoice in PDF format and make the changes manually. You can search for a third-party app to help you edit the downloaded file from QuickBooks.

Here's how to download an invoice:

1. Open the invoice.
2. Click Print or Preview at the bottom part.
3. Hit Print or Preview again. 
4. Click the Download option. 

However, we're unable to suggest a specific app you can use to customize the invoice. I recommend searching online that offers this type of service.

As we assess this, I suggest sending your feedback directly to our product engineers. We continue to improve the features in QuickBooks, and this preference might be available in the future. 

Please follow these steps:

1. Sign in to your QuickBooks account.
2. Click the Gear icon in the upper-right corner.
3. Select Feedback under Profile.

Also, I've attached an article you can use to use charge different customers the same items or services on different dates with an unscheduled recurring invoice: Create the same invoice for multiple customers.

Drop me a comment below if you have any other questions related to your sales transactions in QuickBooks. I'll be more than happy to help. Wishing you a good one.
