This article covers the instructions to resolve the following sync error

• Matched account(xxxxxxxxxxxxxxxxxx) is already linked with another customer: 

Summary:

The customer record looks up for the account in Salesforce and maps to the account when a match is found. If there are two records pointing to the same account this error occurs. 

For example, customer A had already matched with an account and it has synced successfully. Now the second customer say customer B - is also trying to map to the same account as both the matches are pointing to the same account. The mapping should be a unique customer record in Chargebee that maps to one account in Salesforce. To avoid this mapping-related issue, you can ensure that there is only one customer record in Chargebee with the same details and no duplicates. 

Solution:

If you see duplicate records within Chargebee you can delete one of the duplicates or merge these two records using Chargebee merge customer bulk action. 

Note: We recommend testing “merge records” action before performing this action on the live site.
