Built for the complexity of modern professional services
Retain was founded with a single conviction: that professional services firms deserved purpose-built software for resource planning, not retrofitted spreadsheets or generic project tools.
Over three decades, we grew from a specialist scheduling solution into a comprehensive platform serving audit, tax, advisory, consulting, IT services, and engineering supporting over 1.5 million resources worldwide.
Today, as part of AdvT Group, we combine deep domain expertise with cloud infrastructure, AI-powered matching, and seamless integrations, all helping the right people do the right work.
