NextAgency is a comprehensive agency management system featuring CRM and marketing tools. Agencies may extend the capabilities of NextAgency with the NextCommission add-on in order to track commissions, manage sub-agencies and better understand their financial picture. The NextCommission add-on is tightly integrated with NextAgency.
NextCommission Solo is this add-on available on a stand-alone basis. While NextCommission Solo provides basic client and contact tools (as these are needed to assign commissions), it lacks the robust CRM, automation, and marketing tools available with NextAgency.
