3e Software House

3e Software House is a Polish software house founded over 20 years ago, now with 60+ in-house staff spread across developers, testers, PMs, and maintenance specialists. The company has built 93 applications that power multi-million euro operations across ecommerce, logistics, HORECA, and pharma. It positions itself around continuous delivery of complex software—not quick fixes, but systems that run for years without unplanned downtime.

The company's reputation rests on three things: building order processing systems at scale, managing customer loyalty platforms, and maintaining what they build. They've done significant work for global brands (Burger King, KFC, Pizza Hut, DHL, Starbucks, Costa Coffee, Medicover) where the stakes are real—processing millions of orders yearly, managing delivery networks, handling employee benefit schemes.

Services and capabilities

3e splits its offerings into six service lines: custom software, eCommerce solutions, quick commerce, SaaS systems, integrations, and maintenance.

On the custom software side, they build bespoke applications for medium and large companies handling basic business processes—customer service, order acceptance and processing, call center operations, payment and fiscalisation. On eCommerce specifically, they've built order processing systems that handle complicated customization patterns (they cite pizza ordering as an extreme example: client can modify items extensively). These systems run the full lifecycle from order acceptance through distribution, payment, and delivery prep, with workflow tracking and statistical aggregation.

For customers focused on retention rather than pure transaction volume, they build multichannel loyalty and benefit applications. Examples: Starbucks Rewards, Moja Pizza Hut, Medicover Benefits (outsourcing platform for employee benefit aggregation), and Nationale Nederlanden (retirement scheme management). These use points or token systems with gamification, web and mobile interfaces, and are integrated with various POS systems.

They also handle CRM and call center solutions covering customer data aggregation, segmentation, and complex B2B/B2C workflows (non-standard orders, complaints, settlements). On the integrations side, they work with POS systems (Oracle Micros, Agnis), food delivery apps (Uber Eats, Glovo, Wolt, Bolt Food, Take Away), and payment systems.

Their SaaS offering—Ordering Stack—is a cloud-based order management system for restaurants with integrations into Micros 3700 and similar POS systems, food delivery platforms, and optional self-service kiosks. It's positioned as a plug-and-play digital transformation for restaurant chains.

Maintenance services include post-implementation support, technical supervision with SLA-backed repair times, hosting, and server administration. Applications are typically hosted in a failover-class cloud environment with 6 geographically dispersed data centers, 24/7 monitoring, and a dedicated caretaker assigned per client. They also offer traditional or public cloud hosting if preferred.

Notable work

3e's client list reads like a QSR and logistics directory: Burger King, KFC, Pizza Hut, Costa Coffee (the major restaurant chains), DHL (logistics), AmRest (European fast-food operator), Starbucks, Medicover, Nationale Nederlanden. Specific deliverables include:

• KFC in-store kiosks: A dedicated application powering self-service ordering terminals in restaurants
• Burger King kiosks: Follow-on project after KFC success
• Pizza Hut and KFC web ordering platform: Multi-brand, multi-country, multi-loyalty-system platform described as "a real Swiss army knife"
• DHL 24 web portal: Main customer contact point for private and corporate customers in Poland
• DHL Parcel Shop Manager: Application connecting retailers (Żabka Relay, Inmedio, 1 Minute, Freshmarket) into DHL's delivery network
• Starbucks CEE: Web and mobile app for the loyalty program
• Medicover Benefits app: Employee benefit outsourcing tool
• Costa Coffee loyalty system integration: Real-time data exchange with Micros POS

All of these are production systems running continuously; the company emphasizes they process millions of orders yearly and manage extensive logistics networks.

How they work

3e follows an agile methodology by default, though waterfall is offered. The process starts with a Client Requirements Document (BRD and TRD/SRS) that they treat as essential to making projects "well defined and predictable." They conduct business analysis and documentation upfront, then move to transparent development where clients can evaluate modules as they ship and influence backlog ordering.

Quality assurance is woven into the process—not bolted on. They employ continuous integration, test-driven development, and automated testing cycles. Security assurance is similarly integrated: risk minimization is baked into procedures rather than treated as a checklist.

For hosting and operations, they assign a dedicated account representative and caretaker per client. Response times on support requests are typically same-day; they guarantee repair times via SLA. Monitoring is continuous and predictive—they track dozens of critical values (CPU, memory, disk, database query times, business process metrics) to catch issues before users do.

They provide support via phone, email, Redmine, and Slack. On-call coverage is 365 days a year. Post-deployment support includes minor improvements, adaptations to changing conditions, and system consultations.
