We've just dipped our toe in the MCA waters, and are working through developing a separate division of our organization just for MCA, but for our POS and merchant services our best success comes from referrals from other b2b service providers (payroll, equipment, cpa, legal service, security, contractors) and then targeted cold calls where we know the basic details of the business (owner, employee size, years in business, place in market segment, reputation).
