Our Work
We don’t do small experiments. We build the systems that businesses depend on — and we’ve been doing it for over three decades. Here are some of the projects that define what Voittaa does.
TMC — Bespoke Ecommerce Platform
Case Study
Client: The Model Centre — one of the UK’s leading retailers of model trains and collectable models.
The Challenge
TMC had outgrown their Magento-based ecommerce platform. With a catalogue of over 90,000 SKUs and a passionate customer base that surges during new product launches and events, the old system simply couldn’t cope. Site performance degraded under load, the platform crashed during peak traffic, and the business was losing sales at exactly the moments that mattered most.
What We Built
We designed and built a completely bespoke ecommerce platform from the ground up — not a theme, not a plugin, not a modified off-the-shelf product. A purpose-built system engineered specifically for TMC’s business.
The platform integrates directly with TMC’s back-end operations through Brightpearl (Sage), creating an almost fully automated business flow from order placement through to fulfilment. Stock levels, pricing, order processing, and customer communications all run through a single, unified system.
The Results
- £Multimillion in annual revenue processed through the platform
- 90,000+ SKUs managed seamlessly
- 3,000+ concurrent users handled without degradation — where Magento would fall over, our platform doesn’t miss a beat
- 100% uptime since launch
- 4 years in production and still running
Global Asset Tracking — 900 Million Assets Across 30+ Countries
Case Study
Client: A major global industrial distributor operating across 30+ countries.
The Challenge
Our client needed to track 900 million reusable assets through a complex global supply chain. Assets were being lost, stolen, or used by competitors. Safety-critical compliance testing was being missed. Customer relationships were difficult to manage at scale, and production planning was based on guesswork rather than data. The entire operation — upstream and downstream — needed visibility and control.
To make matters significantly more challenging, the entire environment was classified as ATEX and explosive zone work, meaning every piece of hardware and every system deployed had to meet the most stringent safety standards for hazardous atmospheres.
What We Built
We engineered a comprehensive RFID-based tracking system that follows every asset through its complete lifecycle — the very definition of a circular system with reusable assets:
- New asset registration — every asset tagged and entered into the system at manufacture
- Production and filling — automated tracking through filling plants using distributed computing logic
- Logistics and distribution — tracked through the entire supply chain, from warehouse to delivery vehicle to customer site
- Storage and point of sale — visibility at every delivery and sale location
- Customer ordering — customers could order directly via app, with full account and asset visibility
- Return and reprocessing — empties tracked back into production automatically
- Safety and compliance — automatic flagging for safety checks and maintenance at the right intervals
- Work order management — tracking and fulfilment of work orders across the operation
The technology stack used HF RFID with both handheld and fixed readers — all ATEX-rated for explosive environments. Distributed computing was deployed throughout the system to ensure resilience and speed at every node, backed by a bespoke cloud platform capable of handling 100 million transactions in a single hour.
The Results
- 900 million assets tracked worldwide
- 30+ countries covered
- Complete upstream and downstream supply chain visibility
- Theft and competitor usage dramatically reduced
- Fully automated filling plants
- System still running today
NHS Clinical Waste Tracking
Case Study
Client: An independent clinical waste management company responsible for processing 30% of all NHS clinical waste in the UK.
The Challenge
Clinical waste management is one of the most heavily regulated areas in healthcare operations. Our client needed to ensure every bin of clinical waste — from collection at hospital wards through to final processing — was tracked with complete accuracy and a full audit trail. The regulatory landscape is demanding:
- Duty of Care — waste producers must ensure safe management using licensed carriers, with tracking from source to destruction
- Hazardous Waste Regulations 2005 — requires detailed Consignment Notes tracking every movement of hazardous clinical waste
- HTM 07-01 — the NHS standard for Safe and Sustainable Management of Healthcare Waste
- Pre-acceptance audits — processing facilities must audit waste producers (annually for 5+ tonnes/year, biannually for smaller producers)
- Strict storage limits: infectious waste max 14 days, anatomical waste 24 hours (72 if refrigerated), sharps up to 6 months
What We Built
We designed and deployed an end-to-end RFID tracking system covering the entire waste journey:
- Bin tagging — every clinical waste bin fitted with an RFID tag and delivered to hospitals
- Collection — drivers used mobile RFID readers to register the type of waste at the point of collection, creating a digital chain of custody
- Processing plant arrival — bins rolled off the truck onto a weighbridge, where a fixed RFID reader automatically identified each bin
- Automated routing — the system recalled the waste type, displayed a traffic light system to guide the operator to the correct processing path, and recorded the weight
- Automated billing — waste type and weight were logged and billing was generated automatically, eliminating manual paperwork
The system provided complete waste tracking records including service delivery notes, waste acceptance records, and certificates of safe destruction — all generated automatically.
Looking Ahead
This project was ahead of its time. The UK government is now introducing mandatory digital tracking for all hazardous and non-hazardous waste. The NHS has set targets for 95% tracking accuracy and a 50% carbon reduction in waste management. Systems like the one we built are becoming the standard, not the exception.
