What Corrin Software Products does

Corrin Software Products Ltd is a privately held UK software company founded in 1995 and headquartered in Oundle, Peterborough. It is a Pegasus Premier Development Partner (the highest tier of partnership with Pegasus Software) and specialises exclusively in developing add-on modules, bespoke solutions, and third-party integrations for Pegasus Opera 3 and Opera 3 SQL SE ERP systems. The company sells approximately 60 modules organised across two product lines — Opera 3 Products (approximately 45 modules including Advanced Stock Enquiry, MRP, CRM-Plus, Direct Debits/BACS, Email Payslips, Stock Matrix, and POP Authorisation) and Opera 3 SQL SE Products (13 modules) — plus a bespoke custom development service ("Pegasus Bespoke") and an integrations catalogue spanning 40+ third-party applications across HR, CRM, e-commerce, banking, ERP, warehouse management, field service, and vertical-specific platforms. Every module is engineered to maintain the same look and feel as the host Pegasus Opera system, with built-in data updating and validation.

The company's core technology is deep integration with the Pegasus Opera application layer rather than its own standalone platform. Modules operate inside the Opera environment, often leveraging Windows Task Scheduler for automation, supporting multi-warehouse and multi-currency operations, and providing interfaces to regulatory and payment systems (BACS/BACSTEL-IP, AUDDIS, and nine UK pension providers for auto-enrolment compliance). The entire catalogue is offline-downloadable, with product flyers and phone-based sales quoted per module.

Corrin generates revenue through one-time perpetual software licences, sold directly to UK businesses via website download and phone-based sales (01832 279710). The customer base consists of UK SMBs using Pegasus Opera 3 SQL SE or Opera 3 who need extended functionality beyond standard off-the-shelf ERP — workflow automation, batch processing, compliance interfaces, and reporting. No SaaS subscription, channel partner, or recurring revenue model is disclosed. The company has no subsidiaries, no external institutional investment, no disclosed headcount, and operates from a single UK location.

Broad incumbents

• IRIS Software Group: UK-focused provider of accountancy, payroll, HR, and practice management software with a similar SMB and mid-market customer base. Comparable as another UK SMB software consolidator that competes for the same customer wallet and pursues a similar bolt-on acquisition strategy that could apply to Corrin.
• Intuit (QuickBooks): Global SMB accounting/ERP software provider (QuickBooks Online) with a massive third-party developer and integration ecosystem. Comparable as the broader SMB platform whose cloud-native approach and app marketplace define the strategic direction the UK on-premise ERP aftermarket is moving toward.
• The Access Group: Parent company of Pegasus Software and one of the largest UK providers of business software to SMB and mid-market customers. It is comparable as the consolidator that owns Corrin's distribution channel and prioritises the Opera product roadmap that Corrin's revenue depends on.
• Sage Group plc: UK-listed market leader in SMB accounting and ERP software (Sage 50, Sage 200, Sage Intacct). It is comparable as the larger incumbent serving the same UK SMB customer base Corrin's Pegasus customers belong to, and as the dominant alternative platform those customers might switch to.
• OneAdvanced (formerly Advanced Business Solutions): UK-based provider of vertical-specific business software (ERP, payroll, HR, healthcare) with their own partner and add-on developer ecosystem. Comparable as a UK vertical software consolidator with overlapping SMB ERP customers and a similar partner-channel model.
• Pegasus Software: The vendor of the Opera 3 / Opera 3 SQL SE ERP platform that Corrin's entire product portfolio augments. Pegasus is the channel, platform, and the dominant commercial counterparty in Corrin's ecosystem, making it the most directly comparable incumbent even though its business model (core ERP licensing) is fundamentally different.
• Civica: Large UK software group supplying ERP, document management, and payments applications to public sector and SMB customers. Comparable as a UK software consolidator operating in adjacent Verticals and demonstrating the roll-up strategy that Corrin could fit into.

Emerging players

• Acumatica: Cloud-native mid-market ERP with an ISV partner programme and a marketplace of vertical add-on modules. Comparable as the platform whose partner-ecosystem model represents the future of vertical ERP add-on distribution that Corrin may need to migrate toward.
• Xero: Cloud-native SMB accounting platform with a deep third-party add-on marketplace (Xero App Store). Comparable as the disruptive cloud alternative capturing UK SMB customers who might otherwise remain on Pegasus Opera and continue to buy Corrin modules.

Others

• Banyan Software: PE-backed acquirer of small, legacy, vertical-specific software businesses. Comparable as the type of strategic acquirer most likely to acquire Corrin — a profitable, niche, founder-led software company with sticky customers — rather than as a direct competitor.
