BC ERP-system — Transforming Operational Chaos into a Data-Driven Platform
BC ERP-system is designed for operational and strategic management of Bike Center Zaporizhzhia (bc.zp.ua). It consolidates key operational metrics: Gross Income (₴895,841+), Net Profit Margin (43.0%), Rental Starts/Ends (218), Average Check (₴120), fleet utilization (Top/Low Performing Bikes), and a customer database of 1558+ profiles.
Project & Context
Project: BC ERP-system (bc.zp.ua)
Tech Stack: Next.js (React), TypeScript, Tailwind CSS, Vercel Edge Network, Modular SVG/Micro-charts, UI/UX Design System.
Core Goal: Transform local operational chaos into a precision data-driven management platform.
A Single Source of Truth for Bike Center Zaporizhzhia combining financial bookkeeping, Fleet Management, peak load analytics, and customer profiles into a lightning-fast responsive interface.
Problem & Challenges
Rental logs, bike conditions, and revenue entries were scattered across paper logbooks and disconnected spreadsheets, preventing real-time analytics.
Lack of exact rental hour tracking led to high wear on popular bikes (e.g. Leon TN80) while other units sat idle.
Demand spikes during specific time windows (13:00–14:00 & 15:00–16:00) required data forecasting to optimize staff scheduling and maintenance.
Field managers and executives needed instant mobile access without slow page loads or complex navigation.
Data Architecture & Scalability
Clean object hierarchy: Client ↔ Rental Event ↔ Inventory Item (Bike) ↔ Financial Ledger.
SSR and Next.js caching on Vercel Edge Network yield sub-second load times (< 1.0s LCP).
Instant calculation of historical metrics (Gross Income ₴895,841+, Net Margin 43.0%, +12.4% rental growth).
Multi-location support, POS integration, and GPS telemetry ready.
Input Data
Client data acquisition, verification process, order details, and rental equipment info.
Routing & Caching Data
Server-side rendering (SSR), zero latency, and data leak prevention.
Rental Flow Chart & Metrics
Period cash flow tracking (Revenue, Expenses, Profit), key operational averages, and performance ratios.
Fleet Telemetry
Equipment popularity, rental profitability, and real-time wear-and-tear monitoring.
Expanded Data & Reports
Financial reporting, inventory management, invoice generation, customer profiles, and instant cross-system navigation.
Responsive UX Engine
Tailored for administrators on smartphones and tablets in real-world rental hub environments.
Reflows seamlessly from multi-column desktop Bento dashboards to compact mobile card feeds.
Bike cycler controls (Previous / Next bike), client search filters, and active state feedback tuned for touch.
Desktop (1440px+)
4-column Bento layout with high data density, detailed tables, instant search, and micro-charts.
Tablet (768px - 1024px)
Touch-optimized split-view for rapid rental check-in/check-out and inventory scanning at counter hubs.
Mobile (390px)
Single-column swipeable cards, quick bike cyclers, floating status widgets, and touch-first controls.
Core System Modules
Gross Income (₴895,841), Net Margin (43.0%), Average Check (₴120 [-5.11%]).
Rental Starts/Ends (218 [+12.4%]), Peak Hour Detection (13-14 & 15-16).
Bike Performance Card (ID: BC025 Leon TN80 17.5"/29", 52.2h, ₴8,800 revenue, 1st place).
Customer directory with thousands of profiles (1558+ active), direct contact buttons, and rental history.
Design System & Accessibility
The system features a well-conceived semantic base structure and modular design. The implementation of a strict design system with fixed color/spacing tokens and a focus on advanced ARIA mapping makes this dashboard fully compliant with WCAG AA standards.
Optimizing the layout interface for split-second scanability and lower mental load
Modular Structure
Clean grid system using repeating UI components: metric KPI cards (Income, Rentals Start), asset cards, and customer lists.
Consistent States
All cards share uniform trend dynamics presentation (+12.4%, -5.11%), lowering cognitive load and speeding up comprehension.
Information Hierarchy
Key metrics prioritize scale using Display/H1/H2 font sizes, while supporting context is aligned in secondary labels.
Business Impact & Results
Deployment of BC ERP-system transformed operational metrics across Bike Center Zaporizhzhia.
Below is a comparison of key workflows before and after implementing the system:
| Metric / Area | Before | After | Result |
|---|---|---|---|
| Revenue Transparency | Estimates "by eye" at month-end, cash ledger discrepancies | Precise online calculation of Net Margin (43.0%) and Gross Income (₴895,841) | 100% Accuracy |
| Rental Efficiency | Uneven and untracked depreciation of individual bikes | Clear ranking by logged rental hours (e.g. BC025 Leon TN80 — 52.2h / ₴8,800) | Wear Optimization |
| Resource Management | Customer congestion and bottlenecks during peak rental hours | Peak load forecasting, load analysis, and work flow optimization (13:00-14:00 & 15:00-16:00) | -65% Bottlenecks |
| Service Speed | Complex database navigation, slow information processing (Main User Flow 3-15 min) | Instant navigation and operational process acceleration up to 1 second | 3.5x-10x Speedup |
