What ROCKSAND COMPUTERS LIMITED does

Rocksand Computers Limited is a UK-based, privately held transport computing company founded in 1986, headquartered in Hertford, England. The company develops and sells the Pitstop Flag suite of digital tachograph analysis software, which enables commercial vehicle fleet operators to comply with EU Drivers' Hours (Regulation 561/2006) and the Working Time Directive (Regulation 2002/15/EC). The product is a Windows desktop application that runs locally on office or home computers (with optional thin-client deployment via Microsoft Azure or Citrix) and ingests data from all major digital tachograph brands (Siemens VDO, Stoneridge, Actia, Delphi Grundig) via compatible download devices. Core products include Pitstop Company (priced from £215 to £1,110 by fleet size for SMB-to-mid-market operators), Pitstop Lite (basic recording without infringement detection), Pitstop Driver (for freelance/agency drivers), Pitstop Enterprise (multi-user for 70+ vehicle fleets), and Pitstop Bureau (service-provider edition). Complementary offerings include an optional Analogue Chart Scanning Module for mixed fleets, the Digidown Plus hardware download device (£190), the Digidown Terminal WiFi/GPRS remote-download device (£450), and a Bureau Analysis Service for outsourced compliance reporting. The company also operates a Remote Downloading, Tracking & Telematics service with an integrated Vehicle Inspection mobile app.

The business model is predominantly a one-time perpetual software license model with optional annual support contracts (£15-£95), supplemented by hardware sales and outsourced bureau services. Distribution combines a self-serve WooCommerce e-commerce storefront with 30-day free trial downloads and telephone-assisted sales for enterprise customers. Customer segments span SMB haulage, waste management, scaffolding, and logistics operators, alongside named enterprise accounts including NHS Scotland, Serco, the Ministry of Defence, the BBC, IBM Sweden, and Eimskip Iceland. Geographic reach is primarily UK-domestic with selected European customers in Sweden, Iceland, Ireland, the Netherlands, and Belgium.

The company operates with 1-10 employees, has no external funding, no disclosed parent company, and has pursued a bootstrapped, owner-operated model for nearly 40 years. Integration partnerships span Lisle Design (Digidown Terminal), FORS (Fleet Operator Recognition Scheme), Tachosys (digicard readers), and Chequered Flag Training (CPC courses). Strategic product evolution has progressed from Pitstop 5.0 (driver management planner, PDF/HTML reports) through 6.0 (analogue chart scanning) and 7.4 (wall chart reminders, fuel receipt import) to the latest release adding AdBlue expense tracking and enhanced reminder systems.
