Real-time POS-to-ERP synchronisation and a high-concurrency omnichannel commerce engine
Store terminals, online checkout and the central ERP ledger in step, in real time, for a multi-brand GCC retailer.
At a glance
Client
A multi-brand GCC retail and mall conglomerate with 800+ POS terminals and e-commerce storefronts.
Team
1 in-house principal solution architect, 4 senior back-end and POS integration engineers and 1 autonomous QA engineer
Duration
16 weeks
The challenge
Store point-of-sale terminals, e-commerce storefronts and warehouse ERPs ran on delayed 12-hour batch syncs. Inventory was oversold during peak promotions, card settlement reconciliation across acquirers lagged, and checkout was slow.
What we built and connected
Real-time event streaming
We replaced brittle overnight batch scripts with a high-concurrency event streaming layer that synchronises store sales, returns, promotions and SKU stock levels with the central ERP in real time.
Multi-acquirer payment orchestration
One gateway orchestration across Visa, Mastercard and regional GCC switches, with automated T+1 settlement file ingestion and fee auditing.
Inventory reservation under flash-sale load
An ultra-low-latency inventory reservation microservice that absorbs flash-sale traffic spikes without database lock-ups.

Readiness review
In a free 48-hour readiness review, a Principal Architect checks your project against the 6-point Definition of Ready and recommends the track that fits.
Choosing the track
Scope-ready projects receive a binding proposal within 3–5 business days. Concept-stage projects start in the Blueprint Studio. A live system that is failing, undocumented or needs integration starts with a diagnostic of 1–2 weeks. The Blueprint Studio and the diagnostic each have a fixed fee, quoted in the proposal.
