What WINDOWLINK LIMITED does

Windowlink Limited is a UK-based independent software designer founded in 1985, headquartered in Gloucester, England. The company develops desktop-based software solutions for the fenestration industry, serving window, door, conservatory, and glazed extension manufacturers, fabricators, and installers. Its flagship Focus40 product suite provides design, quoting, presentation, survey, and fabrication tools covering casements, doors, composites, bifolds, patios, vertical sliders, and conservatories in PVC, timber, and aluminium materials. The core technology runs on Windows 10 or above without requiring an internet connection for core functionality, positioning it as a reliable solution for manufacturing and field environments. The platform includes specialized features such as superimposition technology for visualizing designs on customer properties, cutting list generation with optimized profiles, CRM integrations with Business Pilot and AdminBase systems, JSON/CSV API linking, and survey reporting capabilities. Mark Dudley, who joined as the first employee in February 1988, leads the company as Managing Director and CEO, and Michele Dudley serves as Data Protection Officer, indicating a founder- and family-controlled ownership structure.

Windowlink generates revenue primarily through recurring subscription packages priced by device count and contract period (monthly, quarterly, or yearly billing, with annual being the cheapest), supplemented by hourly-rate bespoke software development for customizations such as custom frame systems, pricing setups, and custom reports. The company serves primarily mid-market UK fenestration businesses through a sales-led go-to-market motion that combines direct website enquiries, inside phone/email sales at 01452 348 575, live chat (9am-5pm Mon-Fri), a self-serve Quick Pricing Estimate tool for 2+ device deployments, and quote-based sales for manufacturing or 10+ device requirements. Multi-channel marketing includes YouTube tutorials, LinkedIn, Facebook, Instagram, a blog, email newsletter, and a partnership with Purplex Marketing. Customer relationships are notably long-tenured, evidenced by Thames Valley Windows' 13+ year partnership and Kingdom Rooms' multi-year engagement, with documented outcomes around reduced errors, smoother order processing, and improved customer reviews.

Expansion highlights4 records

Direct peers

• First Degree Systems: UK-based provider of window, door, and conservatory design and quoting software for the fenestration industry. Directly competes with Windowlink's Focus40 suite for the same UK fabricator and installer customer base.
• Orgadata (LogiKal): German-based developer of the LogiKal CAD/CAM platform for aluminium, PVC, and timber window, door, and facade fabrication. Comparable to Windowlink in serving the design-through-manufacturing workflow for fenestration companies.
• WindowMaker Software: UK-headquartered provider of window, door, and curtain wall design, quoting, and manufacturing software with global reach. Competes with Windowlink on overlapping fenestration design, pricing, and fabrication functionality.
• Business Micros (BM Group): Major UK fenestration software vendor offering design, quoting, fabrication, and CRM/workflow products to window, door, and conservatory businesses. One of Windowlink's principal direct competitors in the UK market.
• FeneVision (Soft Tech): US-based fenestration software platform providing design, estimating, and production management for window and door manufacturers. Direct functional analogue to Windowlink's Focus40 suite, primarily competing in North America.

Broad incumbents

• The Access Group: Large UK vertical SaaS provider with ERP, CRM, and industry-specific software including offerings that touch the fenestration and wider building products market. Represents a potential horizontal/displacement threat to Windowlink from a much larger vendor.

Regional players

• ProgeWIN (ProgeSOFT): Italian provider of window and door design, quotation, and production software. Comparable to Windowlink in product scope but focused primarily on the Italian and Southern European fenestration market.
