The client is a well-known consumer electronics and IT retailer operating primarily in e-commerce, with a dedicated B2B segment serving business buyers. That B2B operation had grown quickly — and, as often happens, the tooling underneath it hadn't kept pace. Sales was being run across a patchwork of systems and channels, with opportunities tracked in spreadsheets and coordinated over email.

For a retailer whose B2B customers expect fast, professional handling, that fragmentation was a real constraint. Without a central system, it was difficult to know where any given deal stood, to manage a sales rep's workload, or to see the shape of the pipeline as a whole. The company decided it needed a purpose-built CRM to bring the entire B2B sales process into one place — and it needed it quickly.

Pretius built the CRM as a single, central system supporting the entire B2B sales process, serving as the operational layer for sales representatives and managers and integrating with the systems already used across the organization. The platform choice — Mendix low-code — was driven by the need to deliver quickly and integrate smoothly in an environment of frequently changing requirements. Mendix's ready-made UI and backend components, predefined widgets, and strong integration capabilities let the team build functional screens and connect to external tools without implementing everything from scratch.

Where the platform's standard components weren't enough — for example, an advanced multiselect component with complex filtering and selection that the client required — Pretius built custom widgets in React embedded inside Mendix. The team also carved out a set of reusable application components (list views, wizard-style components for multi-step processes) that standardize interfaces and speed up delivery on future Mendix projects.

This was the client's first project with Pretius. It ran as a fixed-price engagement using Kanban and an iterative, Agile-in-practice approach — without classic Scrum or sprints — with daily calls with the client that enabled continuous synchronization, fast reaction to change, and quick implementation of evolving needs. Delivery moved through four connected stages — an initial analysis phase to gather requirements and map key processes, a parallel analysis-and-implementation phase that started development while requirements were still being detailed, a full implementation phase, and a finalization phase that closed out core functionality and synchronized the integrations. Core functionality was completed roughly two months before the production release, with the final phase extended to accommodate the client IT team's systems and to align the integrations between them. The whole engagement ran from kick-off through production release in about four months.

The retailer didn't need a monolithic, multi-year platform. It needed to bring a scattered B2B sales process into one place, connect it cleanly to the tools its people already used, and do it fast – all while the requirements were still taking shape. By building on Mendix, dropping to custom React only where it mattered, and working in tight daily loops with the client, Pretius delivered a production-ready CRM in about four months: a central system that owns the B2B pipeline end to end, hands finalization off cleanly to the back-office, and gives managers the visibility they never had before.
