Assembly is an all-in-one client portal for service businesses such as agencies, consultancies, and professional service firms. The platform consolidates the day-to-day tools a service business uses with clients — client records, communication, payments, file sharing, contracts, forms, and help desk tickets — behind one login. Instead of stitching together separate apps for each function, teams give clients a single destination where requests, documents, and billing all live.
