Lead and Contact duplicates in Salesforce

Hello Community,


We are having a duplication issue where both leads and contacts are being created in Salesforce and Marketo. Here is a little background:


Leads that are created in Marketo are automatically synced to Salesforce if their source is not When they reach 100 points, they are converted into contacts. However, if they make a purchase either on our website or over the phone, a new contact is created in Salesforce (without checking to see if a lead exists first). The contact syncs back to Marketo and we are left with duplicate contacts: 1 lead and 1 contact. How do we prevent this from happening? Is it possible to do so on the Marketo end?
