Hi John Zienda ,

Thanks for reaching out. Did you ever find an answer for this issue? This typically happens due to damaged or corrupted files within your company data.

To resolve this issue, the recommended steps are:

1. Restore a Backup: If possible, restore a backup of your company data from before the error occurred. This can often resolve the issue by reverting to a state before the corruption.
2. Manually Enter a Different ID: While you are addressing the underlying issue, you can manually enter another Customer ID to bypass the immediate error. For tips on renaming, you can click on the Help section within Sage 50.
3. Contact Support: If you don't have a recent backup or continue to experience issues, it's best to contact Sage 50 US Customer Support directly at 866-747-3888. They can provide further assistance and guidance on how to correct the corrupted files or any other related issues.

For more detailed information on this error and the suggested resolution steps, please refer to the article: Error: "The Customer ID that was automatically created already exists in Sage 50".

I hope this helps address your concern. If you have any more questions or need further assistance, please don't hesitate to reach out.

Warm Regards,

Erzsi
