Class level variables are considered bad practice. Instance variables are the preferred way of storing object state.

    def self.build_customer(contents)
      @@customer = []
      contents.each {|row| @@customer << Customer.new(row)}
      @@customer.count
    end

Every class has find_by_* methods. Take a look at method_missing to create dynamic finders for your class attributes. This is exactly how the Rails finders work.
Results from methods can be memoized. You shouldn't have to look up objects every time you call a method to get back the same results.

def transactions
@transactions ||= Transaction.find_all_by_invoice_id(id)
end
