Founded in 1986, Powersoft is an independent software consultancy specialising in modernising business‑critical systems and delivering long‑term technical support. Based in West Sussex and working internationally, we combine deep engineering expertise with practical, hands‑on delivery. We support and develop systems built on PowerBuilder, Oracle, C#, Sage 50 and Microsoft technologies, helping organisations stabilise legacy platforms, extend their capabilities, and plan structured modernisation. Our clients range from companies with large in‑house IT teams needing specialist product knowledge, to organisations with no internal IT function who rely on us for complete system and network support. For over 40 years we’ve designed, built and supported bespoke software across multiple industries, always focusing on clarity, reliability and continuity. Our approach is simple: understand how each client’s business works, engineer solutions that fit, and provide support that genuinely reduces friction. Alongside our consultancy services, we develop and maintain established products for the Hotel & Leisure sector, including Mainstay, our PMS, reservations and back‑office platform for Hotels. Powersoft remains a trusted partner for organisations that depend on stable, well‑engineered systems — and want support they can rely on. www.powersoft-services.co.uk www.mainstay-professional.co.uk www.tstravel.co.uk
