Why do I have Duplicate Customers when I Convert a Lead?
What causes the duplication of customers when converting a lead in Method:CRM.
Updated over a week ago

You may have duplicate customers when you convert a lead. This occurs when:

  1. A lead is created in Method:CRM.

  2. The same customer is created in QuickBooks.

  3. The lead in Method:CRM is converted to a customer.

If you are in QuickBooks Desktop and try to convert the lead to a customer, the customer goes into a sync conflict. If you are in QuickBooks Online, you can't even convert the lead because it will create a duplicate customer.

Solution

To solve this problem, you will need merge the two customers. 

  1. Rename the lead to indicate it's a duplicate. e.g. "Bob Crenshaw2" if the original was "Bob Crenshaw"

  2. Convert the lead to a customer and have it Sync with QuickBooks.

  3. Merge both customers. 

If you wish to merge customers in QuickBooks Desktop, simply rename the duplicate customer, e.g. "Bob Crenshaw2" to the original name. QuickBooks will prompt you to merge them. 

If you wish to merge the customers in Method, please see our article Merge Contacts and Customers.

Once you do that and it syncs, then all the transactions and all the activities, opportunities, etc., will be merged under one customer.
