Retain Cloud vs. BigTime

The Only Platform Built to Unify Resource Planning for Professional Services — Now with AI and Enhanced Skills Taxonomy Established in 1992, Retain is the world’s first platform built to give professional services firms and complex, multi-entity organisations one place to plan, schedule, and forecast across every department. No more spreadsheets. No more disconnected tools. Just a single, intuitive system that brings clarity and control to resourcing. With AI-powered insights, a governed skills taxonomy, and behavioural profiling, Retain goes beyond availability.

BigTime Software: The AI-powered professional services platform enabling intelligent decisions and delivering profitable growth. Too many firms rely on disconnected quoting tools, spreadsheets, and manual handoffs between sales and delivery. This creates misaligned expectations, margin erosion, and frustrated clients. BigTime changes that. We unify the entire professional services journey—from scoping and quoting to staffing and invoicing—so you can sell with confidence, deliver with precision, and grow with profitability.
