What PowerSoft Computer Services does

PowerSoft Computer Services Limited is an independent UK software house founded in 1986 in Horsham, West Sussex, and incorporated in 1991 by co-founders Colin Eley and David Peace. The company specialises in bespoke software development, PowerBuilder consultancy and migrations, and Sage 50/200 customisation, supported by Microsoft .NET development. Its technology stack centres on PowerBuilder (PowerScript), EAServer, PowerServer/Cloud, and major databases (SQL Server, Oracle, SQL Anywhere, PostgreSQL), with two proprietary products: PSSOP50, a configurable Sales Order Processing front-end for Sage 50, and Mainstay Professional, a hotel property management system with two-way integration to 150+ booking channels (acquired May 2015).

The business operates a sales-led, direct enterprise motion targeting organisations with legacy PowerBuilder or Sage estates — including insurance and reinsurance (Klapton), banking (American Bank, Kansas), higher education (Western University), chemicals/oil & gas, FinTech (Inara Transfers), and a Mainstay-customer base of 100+ hotels. Revenue is generated through multi-year consultancy engagements, ongoing tiered support contracts, and one-time product licences for PSSOP50 and Mainstay. Customer relationships are characterised as long-term partnerships, often spanning decades, with mission-critical systems that create high switching costs.

Powersoft positions itself as the European and American centre for Appeon PowerBuilder consultancy and as an Approved Sage Developer, with a documented international footprint spanning 11 countries across Europe, North America, Oceania, the Middle East and Africa. The company employs 1-10 people, is privately held with no external investment, and has celebrated 40 years of continuous trading in 2026.

Scale indicators9 records

Recent moves9 records

Expansion highlights5 records

Direct peers

• Appeon: Owner and developer of the PowerBuilder platform. Powersoft is an approved Appeon consultancy and Appeon's designated European and American centre, making Appeon both a platform partner and the closest direct comparability anchor for Powersoft's PB migration and support work.
• Cloudbeds: Cloud-based hotel property management system with broad channel manager integrations. Most direct modern comparable to Mainstay Professional for mid-sized hotels, though Cloudbeds is SaaS-native versus Mainstay's on-prem/PowerBuilder architecture.
• ISC Software Solutions: UK-based Sage development partner offering bespoke Sage 50/200 customisation, add-ons, and integrations. Directly comparable to Powersoft's Sage customisation practice, PSSOP50-style add-ons, and mid-market UK customer focus.
• Hotelogix: Hotel PMS with multi-channel distribution aimed at small and mid-sized hotels. Directly comparable to Mainstay in customer profile and channel-management positioning, with similar focus on independent and group hotels.

Broad incumbents

• Sage Group: Owner of the Sage 50/200 accounting platforms on which Powersoft builds. Powersoft is an approved Sage developer, so Sage is both an ecosystem anchor and a broader incumbent that defines the platform boundaries Powersoft operates within.
• Accenture: Largest global systems integrator with deep legacy-to-cloud modernisation capability. Comparable at the enterprise modernisation and bespoke-development level where Powersoft has historically competed for high-end engagements (e.g., banking).
• Cognizant: Global IT services and modernisation provider. Comparable to Powersoft's bespoke enterprise software work and migration services, with significantly broader stack coverage and delivery scale.
• Capgemini: Global IT services firm with an extensive legacy application modernisation practice. Competes for the same enterprise migration and modernisation RFPs Powersoft targets, though at vastly larger scale and across multiple stacks beyond PowerBuilder.

Emerging players

• EPAM Systems: Custom software engineering and modernisation services firm with strong presence in financial services and insurance. Comparable to Powersoft's bespoke insurance, banking, and migration work for regulated enterprise clients, though at materially larger scale.
• Mews: Modern cloud hotel PMS competing for the same mid-sized and boutique-hotel segment that Mainstay targets. Comparable via PMS product category and channel-integration depth, though Mews is consumer-of-cloud while Mainstay is legacy-on-prem.
