If your business logic is related to creation of different objects for different vendors, you can use Factory Method / Factory_ patterns.

If your business logic is related to change behaviour of system for different vendors, you can use Strategy_pattern

Refer to related SE questions for more details about these patterns:

What is the basic difference between the Factory and Abstract Factory Patterns?

You may use an interface, CompanyTemplate which will contains all the common methods that should be implemented by company A, B and C - 

public interface CompanyTemplate{

   public someCommonMethod();

}

After that A can inplement CompanyTemplate - 

public class A implements `CompanyTemplate` {

  public void someCommonMethod(){
     //implementation code
  }  

  //Other methods special only for company for A

}

Smells like Strategy Pattern to me: link

Inside interface define method(s) which will be performed by concrete vendors. Concrete vendor have to implement interface and add own implementation of method (strategy).
