Hi CF_Pro,
This really depends on how you want to organize your QuickBooks data, and has little to do with Method. Since the company name will always be the company name, the question really comes down to how you'd like to utilize the Customer Name in QuickBooks. Understand that Method will sync with whatever you decide to use in QuickBooks as the Customer Name. I know some users have the main contact person for the company as the Customer Name and some use the company name as the Customer Name in QuickBooks.
I don't believe there is a right or wrong way to do this, just more of a personal preference and perhaps how you define the customer for your business. If you do business with individual people, maybe use the person's name as the customer. If you sell to businesses, perhaps the company name. The decision on how to use this field is really up to you and your business.
Hope this helps,
- Adam
