Business Logic Duplicated Across Platforms
Domain rules were being implemented separately for different platforms, leading to inconsistent behaviour, platform-specific bugs, and doubled QA effort with every change.

The Challenges
Replacing a Paper-Based Petrol Pump Operation While Keeping a Legacy Accounting System at the Centre
A petroleum retailer serving both general customers and corporate fleet accounts set out to replace its paper-based operation with a fully digital shift management and fuel tracking ecosystem.
The brand faced several challenges:
Manual Release Processes Creating Risk
Mobile releases, app store uploads, and code signing were entirely manual, with no controlled promotion flow, making it impossible to prevent untested or unauthorised code from reaching production.
Data Mapping Inconsistencies Between App and Backend
Data Mapping Inconsistencies Between App and Backend The absence of centralised data contracts meant the mobile app and backend services were mapping data differently, causing errors that were difficult to trace and reproduce.
No Structured Quality Gate Before Production
There was no formal mechanism to enforce that every release met a defined quality standard before it went live, leaving release stability dependent on individual process adherence rather than systemic controls.
The Solution
A Shared-Core Architecture and Release Discipline That Made Quality a System, Not a Practice
Kombee delivered a cross-platform React Native application built on a shared business logic core, with an automated testing framework and a formal release governance model that made every production release predictable and traceable.
01
Shared Business Logic Core and Platform Architecture
Centralised Domain Layer as the Single Source of Truth
A centralised Shared Core Repository serves as the single source of truth for all business rules, authentication logic, pricing, and data contracts, ensuring the same logic drives behaviour consistently across mobile and any future platform without duplication. The Platform Adapter Pattern enforces a strict boundary where shared code never directly calls platform-specific APIs.
Role-Based Access and Job Lifecycle Management
The full job lifecycle from Create through Edit, Quote, Payment, and Completion is managed within a single structured flow, with role-based access control enforced across all three user types; Installers, Admins, and Billing Personnel. Push notifications via Firebase FCM are routed intelligently using deep links, taking users directly to specific job details during active field operations.
A shared architecture that eliminated logic duplication at the root, making the platform consistent, maintainable, and ready to scale across any future surface.
02
Parts, Distributor and Financial Integration
Real-Time NAGS Parts Search and Distributor Ordering
Real-time NAGS parts search gives users accurate, up-to-date parts and pricing data directly within the job workflow, with direct distributor ordering available without leaving the app. Biometric authentication via Azure AD B2C gives installers and billing personnel a fast and secure login on both Android and iOS.
EDI Invoice Automation With Failure Retry
EDI invoice submission is fully automated with built-in failure retry mechanisms, ensuring billing records are processed accurately even when submission encounters errors. Automated error recovery prevents revenue loss from manual billing gaps that previously required individual intervention to resolve.
An integrated glass ecosystem where parts, pricing, ordering, and billing operate as one connected workflow with no manual handoffs between systems.
03
Automated Testing, CI/CD and Release Governance
End-to-End Test Suite and Quality Gates
An end-to-end test suite built on Appium 2.x, WebdriverIO, and a BDD plus Page Object Model framework provides structured, maintainable automated coverage across all critical user flows. A smoke automation suite targeting under 10 minutes runtime triggers on every pull request, with zero open Sev1 and Sev2 defects enforced as a non-negotiable gate before any production release.
Formal Git Promotion Flow and Shift-Left Testing
A formal Git promotion flow from development through stage as a Release Candidate to production, combined with strict JIRA-based branching and back-merge policies, ensures every line of code reaching production is traceable, reviewed, and approved. A shift-left testing culture makes unit tests mandatory for all shared logic, with developers owning validation early in the lifecycle.
A release governance model that turned an unpredictable, manual process into a controlled, documented pipeline where quality is enforced by the system itself.
