Five Line Systems

What Five Line Systems does

Five Line Systems AB (FLS) is a privately held Swedish custom software development firm founded in 1999 and headquartered in Osby, southern Sweden. The company is owned by co-founders Joachim Hansson and Mattias Carlsson, who have controlled the independent entity since September 2002 following its separation from founding parent Delta Plast. FLS serves small and medium businesses across manufacturing, transport/logistics, security services, and adjacent verticals in Sweden, delivering bespoke desktop, server, mobile, and web applications. With 1-10 employees, the firm operates a project-based, direct-engagement model with no public pricing or self-service channels.

The company's core proprietary product is Lucid, a complete ERP/business system built entirely from scratch and comprised of nine integrated modules: Contacts, Articles, Customer Orders, Purchasing, Production, Shipment, Invoicing, Accounting, and API Connections. Lucid's architecture supports deep customization, native bidirectional integration with Fortnox (Sweden's dominant SMB accounting platform), EDI order receipt via the Peppol BIS Ordering 3 standard, and JSON-REST connectivity to external transport and supplier systems. A complementary mobile product, Frasse (Chaufförs-App), provides Android/iOS delivery management with route planning, barcode-driven pallet returns, and receipt printing. The development stack spans Delphi/Embarcadero and Microsoft SQL Server as the foundation, augmented by PHP, JavaScript, Node.js, React Native, TypeScript, and a portfolio of database technologies (SQLite, MySQL, MariaDB, MongoDB).

Revenue is generated through three streams: project-based custom software development, Lucid ERP deployment and customization, and system integration services. All engagements are priced on a quote basis tied to client requirements and scope, with multi-year contract cadences. Distribution is exclusively direct, with a single-country Swedish footprint, a partner network for ancillary capabilities (BeginIT, Compenta, Kaxig, Delta Data), and core technology relationships with Fortnox, Embarcadero, and Microsoft. The company has no disclosed institutional investment, no subsidiaries, no patents or trademarks on file, and no awards or regulatory actions recorded.

Broad incumbents

• Visma: Large Nordic provider of business software including accounting (Visma eEkonomi, previously Jeeves), ERP, and HR for SMBs and mid-market. Comparable as a dominant Nordic ERP/accounting ecosystem player that competes for the same Swedish SMB wallet.
• IFS: Global enterprise ERP and EAM vendor with strong presence in manufacturing, service management, and asset-intensive industries. Comparable as a broad ERP incumbent whose off-the-shelf functionality could displace custom ERP builds like Lucid over time.
• Vitec Software Group: Public Swedish vertical software acquirer and operator. Comparable as a Nordic business software platform serving niche verticals, though Vitec operates via buy-and-hold of multiple software products rather than bespoke builds.
• Hogia: Nordic business software group offering ERP, payroll, transport, and public-sector software. Comparable as a Nordic incumbent providing ERP-style systems to SMB and mid-market customers, though at significantly larger scale than Five Line Systems.

Regional players

• Centsoft: Swedish ERP/business system provider focused on SMB customers in manufacturing and wholesale. Comparable to Five Line Systems in targeting Swedish SMBs with customizable ERP modules and accounting integrations.
• Björn Lundén: Swedish provider of business software, accounting, and ERP solutions primarily for SMBs and accounting firms. Comparable as a regional Swedish ERP/business software vendor competing for similar SMB customers.

Others

• Fortnox: Sweden's leading cloud accounting platform and a direct technology partner of Five Line Systems via Lucid. Comparable as an adjacent Swedish SMB software platform whose ecosystem position shapes Lucid's distribution and feature roadmap.
• Custom Development Houses in Sweden: Swedish custom software development and integration firms (e.g., Solidify, Softhouse) serving enterprise and SMB clients with bespoke systems. Comparable as competitors and partners in the same custom-software-services segment that Five Line Systems operates in.

Direct peers

• Pyramid Business Solutions: Swedish ERP and business system provider serving SMBs with modular software and customization services. Comparable to Five Line Systems as a regional Swedish vendor offering both packaged ERP and bespoke development against Fortnox and similar ecosystems.
• Monitor ERP: Swedish-headquartered ERP vendor focused on manufacturing and production-oriented SMBs. Directly comparable to Lucid because it targets similar Swedish manufacturing SMBs with modular ERP covering orders, production, purchasing, and integration with accounting/EDI.
