The Operational Challenge
The client operated multi-currency stores across Scandinavia and the Baltics with distributed warehouse inventory. Asynchronous batch polling caused inventory drift of up to 18 minutes, resulting in frequent overselling during peak sales campaigns and manual tax re-allocations.
The Engineering Solution
Konero Europe engineered a dedicated webhook ingestion gateway featuring HMAC signature verification, distributed idempotency keys in Redis, automated exponential back-off retry queues, and direct integration with PEPPOL BIS Billing 3.0 electronic invoicing.
Production-tested middleware architecture.
Event-driven infrastructure designed for high throughput, cryptographic validation, and statutory compliance.
