Harmony is a retail-focused inventory and point-of-sale system designed to support day-to-day store operations. It was built for a supermarket focused on made-in-Nigeria products, but is adaptable to other retail environments.
The system is used by store staff to manage sales and inventory, and by administrators to monitor operations and vendor activity. It is available on web and mobile, currently as an internal tool with potential for external deployment.
The Challenge
High cost relative to the value delivered
Features that did not match actual store workflows
Less intuitive interface for daily operational use
Inefficiencies and unnecessary spending on a misaligned tool
Gaps between operational and administrative workflows
How we approached it
Store staff can easily log sales and manage inventory in one place
Admins can track activity, stock levels, and performance centrally
Both operational and administrative workflows supported in a single system
Simpler, more intuitive interface designed around real store processes
Built-in sales reporting and insights for better decision-making
What it delivered
Reduced operational cost by replacing a high-cost, misaligned system
Simpler and more intuitive interface aligned to real store workflows
Improved visibility into sales activity and inventory levels
More control for administrators across locations
Potential for external commercialisation beyond initial internal deployment
Why it matters
Replacing an oversized, misaligned system with a right-sized platform lowers total cost of ownership without sacrificing capability
Centralized visibility across stock, sales, and locations improves inventory accuracy and reduces shrinkage risk
A workflow-aligned interface shortens staff onboarding and reduces operational errors
Integrated reporting supports faster, evidence-based stocking and pricing decisions
How we built it
- 1
Research
Identified gaps in the current system and areas of unnecessary complexity through direct engagement with store staff and admins
- 2
Design
Mapped features directly to real store workflows rather than designing in the abstract; simplicity was the primary design principle
- 3
Build
Cross-functional team covering backend, frontend, QA, DevOps, and product working in iterative cycles
- 4
Test & Iterate
Multiple release cycles based on real usage; live feedback shaped refinements
- 5
Deploy
Post-launch feedback loop maintained to keep the system reliable while continuously improving
- 6
Feedback Prioritisation
Urgent issues (especially around sales and inventory) fixed quickly; improvements planned into future releases; lower-priority requests documented
