A Gulf Retail Group Keeps 800+ Tills and Its Online Stores in Sync in Under 250 ms
Store terminals, online checkout and the central ERP ledger in step, in real time, for a multi-brand Gulf retailer.
At a Glance
Client
A multi-brand GCC retail and mall conglomerate with 800+ tills 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.

Choosing the Track
Scope-ready projects receive a binding proposal within 3 to 5 business days. Concept-stage projects start with Discovery and Design.
