Apadua GmbH
A modular, event-centric B2B procurement marketplace built for enterprise scale.
01 / Overview
The Scope & Objective
Apadua required a next-generation B2B procurement marketplace capable of supporting complex multi-vendor tender workflows across European enterprises. The platform had to enforce strict compliance rules, support multi-currency transactions, and integrate with existing ERP systems.
02 / The Challenge
Operational Friction & Bottlenecks
Legacy procurement tools forced buyers into rigid, non-configurable workflows with no real-time event visibility. Tender cycles that should have taken days were stretching into weeks due to manual approvals and siloed vendor communication.
03 / The Solution
Architectural Implementation
We architected a Vertical Slice Architecture with Domain-Driven Design boundaries, enabling independent feature development across procurement, vendor management, and analytics domains. An event-sourced core ensured every procurement action was auditable and replayable.
