How do you determine if an Account already exists in Sales Cloud before you create an account in Sales Cloud from Eloqua?

Use case / Process flow

1. We import a list of contacts into Eloqua with the company field populated; multiple contacts could have the same company name.

2. When a contact hits a certain lead score we want to create an Account, Contact and Lead in Sales Cloud.

Issue:

1. When multiple contacts with the same company name reach the lead score it leads to Eloqua creating multiple accounts in Sales Cloud with the same account name.

Please let me if I am doing anything wrong here.
