As of my last knowledge update in January 2022, I don't have the specific capability to provide real-time information about the features or updates in QuickBooks Online. The ability to edit an invoice ID after it has been created and sent may depend on the version of QuickBooks Online you are using and the specific permissions granted to the user.


In general, invoice IDs in accounting systems are often used as unique identifiers and are not intended to be changed once an invoice has been created. This is to maintain accurate records and prevent potential confusion.


Here are a few steps you can take:


1. **Check QuickBooks Online Documentation:**

   - Refer to the official QuickBooks Online documentation or user guides. They often provide detailed information on the functionalities and limitations of the software.


2. **Contact QuickBooks Support:**

   - If you're unsure about whether you can edit an invoice ID in your specific version of QuickBooks Online, consider reaching out to QuickBooks support. They can provide accurate and up-to-date information based on your account and version.


3. **Consider a Workaround:**

   - If you need to make adjustments, you might consider adding a note or memo to the invoice to explain any changes. However, keep in mind that this doesn't change the actual invoice ID.


Remember that making changes to invoice IDs or other critical details may have implications for your financial records and reporting. Always exercise caution and consider consulting with your accountant or financial advisor for guidance specific to your business needs.


Since software features and capabilities can change, it's advisable to check the most recent information from QuickBooks Online or contact their support for the most accurate guidance.
