B2B SaaS refers to business-to-business software-as-a-service. It is a cloud-based software platform used by businesses for many tasks, including financial services, project management, product information management (PIM), customer relationship management (CRM), enterprise resource planning (ERP) and other B2B related services.
Companies subscribe to B2B SaaS solutions and pay a recurring fee, typically on a monthly or yearly basis. Instead of downloading or installing these services on a computer, businesses access the software via a cloud based application or website created by a SaaS company.
