Thanks for sharing your queries here with us today. I appreciate you coming into this forum, and I've come to provide detailed assistance to help you enter additional items into a completed invoice.
You can add the November 8 service date to the invoice transaction created and drag the current added item between the dates November 1 and 15. To do this:
- Open the invoice you want to modify.
- Enter the November 8 service item date and other info.
- Click on the Nine-dot icon and drag the current added line item between November 1 and 15.
- Review all details, then click Save & Close.

Additionally, you may want to customize or add specific information on your sales forms to create personalized and professional-looking invoices. Once your customers are ready to pay, record and track the invoices paid to link the transactions and make your account balanced.
I'll be looking forward to any questions you may have when managing customer invoices in your file. Feel free to mention me anytime in this thread, so I can provide further help. Keep safe and have a good one!
