Hi Ebony99
Thank you for your post. Welcome to the Community Forum.
What you are doing is right. For the system to realize what the next invoice number should be, you will need to manually change it for a few invoices before it catches up. Another thing to check is if you're also creating quotes with a different number sequence. Invoices and Quotes now use the same number sequence. If you have Invoice no. 003 and Quote no. 001, your next invoice will be 002 until they are both the same. I also suggest that you try Clearing the AccountRight Cache to help the system catch up faster.
Please feel free to post again. I'm happy to assist further.
