Carmedia.bg online store concept
Carmedia.bg is a large-scale ecommerce project for car multimedia, monitors and accessories, where a standard online store structure simply isn’t enough. That is why the project was built as a custom OpenCart system with extended product logic, inventory sync, B2B access, external exports, marketing integrations and dedicated mechanisms for managing complex product combinations.
Key project information
Carmedia.bg is a custom online store for car multimedia, built on OpenCart with a highly specific product architecture, B2B features, CRM/inventory integration, courier and payment modules, export systems and full technical readiness for ongoing SEO and performance marketing.
About the project
Carmedia.bg is an online store in the automotive niche, focused on multimedia units, monitors, navigation, MMI solutions and accessories for a wide range of car brands. With products like these, a standard ecommerce model often falls short, because customers aren’t just looking for an item — they need a compatible solution for a specific car, model, year and configuration.
The project is built on OpenCart, but with deep custom logic on top of the standard platform. Some products are displayed as a single complete product, yet in the admin they can be assembled from several component parts. This allows more flexible management of offers, stock, prices, accessories and variants.
We built a dedicated mechanism in the admin panel that lets the team define, when creating a product, whether it is a standard product, a product with variations or a combination of several component parts. The site is therefore not just a catalog, but a real system for managing complex product configurations.
Beyond the public storefront, Carmedia.bg includes serious backend infrastructure — integration with a CRM/inventory platform, B2B access for partners, sync of products, customers and sales, exports to external platforms, an XML feed for partners and marketing tracking modules.
What we built
The project was delivered as a complete ecommerce system in which design, product architecture, inventory logic, B2B access, marketing integrations and external syncs all work together.
Custom OpenCart online store
We built an OpenCart foundation with extensive custom enhancements so the system can serve a complex product catalog and real business processes.
Custom UI/UX design
We developed a visual structure suited to technical products, a large catalog, product filters and a clear path to purchase.
Complex product variations
Logic is in place for products with multiple variants, configurations, choices and parameters based on specific vehicle compatibility.
Composite products
We built a mechanism that lets a single product be assembled from several component parts while still being shown as one complete solution.
CRM/inventory sync
The site is integrated with an inventory CRM platform to sync products, sales, customers and operational data.
B2B partner platform
We built B2B functionality for dealers and partners, giving them access to additional information, products and accessories.
Global discounts
We developed discount mechanisms by category, attributes, keyword markers in product names, product traits and component parts.
Payment and courier modules
Multiple payment methods are integrated — cash, card, bank transfer and installments — along with courier modules for delivery.
Custom product descriptions
We developed a dedicated template for long HTML descriptions with a modern structure, better readability and stronger product presentation.
Custom filters and categories
Custom filters, categorization logic and a module for quickly moving, reordering and grouping categories are in place.
XML and marketplace exports
We developed exports and syncs to external platforms such as eMAG, Pazaruvaj and XML feeds for partners.
Marketing tracking modules
Modules for Google Tag Manager, Pixel, Google Ads ID, tracking and ongoing performance marketing are integrated.
Desktop design
The desktop version of Carmedia.bg is designed to handle a large technical catalog — with clear navigation by car brand, product group, accessories, filters, CTAs and detailed presentation of product variants.
Mobile look and mobile UX
On the mobile version of Carmedia.bg, the main focus is fast orientation in a large product catalog. Shoppers often look for a product for a specific car, model or series, so the mobile structure has to help them quickly reach the right category and the right product.
The mobile UX logic emphasizes clear navigation, convenient product cards, visible CTA buttons, easy browsing of variants and a shorter path to an inquiry or purchase.
CRM, inventory sync and product architecture
One of the most important parts of Carmedia.bg is the integration with the company’s own CRM/inventory platform. Through it, the site doesn’t work in isolation but as part of a larger business system in which products, sales and customers can be synced and managed more efficiently.
This is especially important for a catalog with many technical products, variations, component parts, accessories and specific stock levels. Instead of being limited to a standard product form, the admin is extended with custom mechanisms that give better control over how products are built, displayed and sold.
The result is a more flexible ecommerce system that can serve end customers as well as partners, dealers, external platforms and marketing channels.
B2B access for dealers and partners
For Carmedia.bg we developed a B2B platform that gives dealers and partners special access to content, products and accessories that are not part of the standard public shopping experience.
This logic matters for businesses that sell both to end customers and to a partner network. Instead of maintaining separate channels by hand, the B2B functionality enables a clearer separation of user roles, access, information and commercial opportunities.
Global discounts and product rules
Discounts by category
The system supports discounts on products from specific categories, making it easier to run campaigns by product group and vehicle segment.
Discounts by keyword marker
We developed logic for applying discounts to products with specific markers or traits in their names.
Discounts by attribute
The mechanism allows discounting products by shared parameters and attributes, with no need to handle each item manually.
For Carmedia.bg we developed a dedicated global discount mechanism that goes beyond standard single-product price cuts. Discounts can be managed by different criteria — categories, text markers, attributes, product parameters and even component parts.
This lets the team launch more flexible campaigns, manage promotions across large product groups and create commercial scenarios that standard OpenCart features don’t cover well enough.
XML exports, external platforms and tracking
The project includes custom modules for product export and sync to external platforms such as eMAG, Pazaruvaj and other channels. This lets the product catalog be used not only on the site, but also in partner and marketplace environments.
We also built an XML export mechanism that makes it easier for the company’s partners to pull and use product information. It is an important part of B2B growth and automating the sales network.
In addition, custom modules are in place for Google Tag Manager, Pixel, Google Ads ID, tracking and other marketing integrations needed for ongoing performance marketing, remarketing, conversion tracking and campaign optimization.
SEO foundation, content and AEO-friendly structure
Structure by car brand
The site is built to serve searches by brand, model, product group and compatibility — key in the automotive niche.
Long product descriptions
We developed a dedicated HTML description template that presents technical information in a more modern, readable and structured way.
Ready for AI search
Clear categories, attributes, product parameters and descriptions help the content be better understood by search engines and AI-driven systems.
