Executive Summary
The client required a complete digital overhaul of an existing medical supply buyback website. The primary goal was to replace a legacy system with a high-performance, mobile-responsive platform capable of complex, automated pricing logic based on product expiration dates and condition. Lime Street developed a custom WooCommerce-based Buyback Engine that synchronized product inventory with dynamic “rolling” expiration rules, resulting in a scalable, user-friendly platform ready for future CRM integration.

Client:
Medical Device Procurement Sector
Industry:
Health-Tech
Core Objective:
Replace a legacy site with a custom WordPress “Buyback Engine” to automate date-sensitive pricing and optimize mobile lead capture.
The Challenge
The client’s original site lacked the sophisticated logic required for the medical buyback industry. Key obstacles included:
Manual Pricing Hurdles
Pricing for products fluctuates based on expiration months. The client needed a system that “rolled” forward automatically every month without manual updates.
Lead Capture Friction
The need to balance high-intent lead generation (SMS/Email capture) without discouraging users from completing a quote.
Complex Logistics
Integration of a “We Come to You” courier service restricted by specific zip code ranges.
Legacy Infrastructure
A full deletion of the previous site structure was required while maintaining SEO integrity.
The Solution
Lime Street implemented a multi-phased development strategy focused on functionality-first deployment.
1
Technical Architecture
Core Platform: WordPress + WooCommerce + Elementor.
Custom “Buyback” Plugin: A proprietary logic layer built to handle:
- Rolling Expiry Offsets: Users select dates from a dynamic dropdown that automatically updates based on the current date (e.g., “Long Dated” always equals 13–24 months from today).
- Hierarchical Rule System: Deduction logic applied at three levels (Global, Brand, and Individual Product) to allow for granular profit margin control.
Lead-to-Unlock Workflow: A “Price Unlock” mechanism requiring SMS capture before displaying the final offer, stored via browser cookies to prevent repetitive friction.

Design & UX
Reference-Based UI: Developed a clean, professional interface modeled after industry leaders, utilizing a brand’s palette.
Mobile-First Navigation: Optimized “sticky” headers with one-touch “Call/Text” functionality and a streamlined mobile checkout.
Logistics Engine: A zip-code validation tool at checkout to toggle between “Local Pickup” and “Mail-In” options.
Implementation Process
Phase I: Infrastructure
Staging environment on IONOS; full data/SEO audit, SEO metadata migration.
Phase II: Core Logic
Engineering of the custom calculation engine and rolling expiry offsets.
Phase III: Data Integration
Bulk catalog upload, brand categorization, and rule-set configuration.
Phase IV: UX Refinement
Mobile responsiveness, sticky headers, and account dashboard styling.
Phase V: Analytics & SEO
Google Ads GTAG deployment and preparation for CRM (Odoo) sync.
The Results
Lime Street implemented a multi-phased development strategy focused on functionality-first deployment.
1
Automated Maintenance
The “Rolling Month” logic eliminated the need for monthly manual price adjustments, saving the client hours of administrative work.
2
Enhanced Lead Quality
The SMS capture workflow successfully bridged the gap between anonymous browsing and qualified lead generation.
3
Scalable Backend
The system was confirmed compatible with Odoo CRM, providing a clear roadmap for Phase 2 (shipping labels and automated invoicing).
4
Scalable Backend
Despite a late-stage shift in the client’s internal business strategy, the project was delivered as a “clean, organized codebase” that served as the architectural inspiration for their in-house systems.
Conclusion
This project demonstrates Lime Street’s ability to solve complex logical problems within the WordPress ecosystem. By building a custom calculation engine rather than relying on “out-of-the-box” plugins, we provided a medical buyback solution that was both mathematically precise and commercially aggressive.

You guys have been great. While I share some regret that we didn’t get to put out your work, it was a big inspiration in revealing what we weren’t even aware of. You get a lot of credit for that.
