A single OpenCart 3 platform with external accounting-system integration, custom design, and different pricing models for retail customers, distributors, and large wholesale buyers.
The online store lets shoppers browse a large catalog of women's clothing, filter by season, collection, size, and stock, add items to the cart, and place orders. Logged-in users see different prices and minimum order quantities depending on which segment they belong to — retail, small distributors, or large wholesale partners. Catalog, stock levels, and base pricing are synchronized with an external ERP. From there, the client's team enriches product pages with images, descriptions, and marketing blocks. Completed orders are sent back to the ERP, where warehouse and finance pick them up.
Yunus runs a company that manufactures women's clothing and works simultaneously with B2C customers, smaller partners, and large wholesale buyers. Previously, product records and pricing lived in the ERP, while online sales were still semi-manual. The catalog was updated by hand, wholesale prices were negotiated in email threads, and orders were re-entered into accounting manually. Yunus wanted a store that would become a true front layer for the ERP — while still looking like a premium branded storefront.
External source of truth
All product data, stock levels, and base prices lived in an external system. The site had to work as a storefront without duplicating the logic of the accounting platform.
Multiple sales models
The store had to combine retail sales, small distribution partners, and large wholesale buyers — each with its own pricing policy, minimum-order rules, and catalog access.
Custom design
The client had strict requirements for visual presentation and layout structure. Standard OpenCart themes weren't going to cut it — the project needed a fully custom frontend and CMS integration.
Order synchronization
Every order placed on the site had to move safely and quickly into the accounting system, with every attribute warehouse and finance needed.
Content management
The ERP only provided technical fields and prices. Product storytelling, image galleries, and promo blocks had to be managed on the site side.
Stability under load
With high visitor counts, lots of products, and active filtering, pages had to stay fast — and the integration processes couldn't slow the storefront down.
We built the store on OpenCart 3 with a fully custom frontend, a dedicated integration module for the external accounting system, and flexible pricing rules per customer segment. Catalog, stock, and base prices come from the ERP; on the site they're enriched with content; completed orders flow back to the external system for processing.
Sales flows for three customer segments
At the start, we fixed how the three models — retail, small distributors, large wholesale — would actually work. Who sees which catalog views, what the minimum order quantities are, how prices are formed, which payment and delivery methods are available per group. From there, we designed flows for guest browsing, partner login, wholesale "box" ordering, and repeat collection orders.
Two-way integration
The import/export module pulls products, SKUs, base prices, stock, and technical attributes from the ERP on a schedule, and sends order data back after checkout. The update mechanism preserves site-specific content — images, SEO fields, descriptions — while keeping technical fields synchronized with the accounting system.
Pricing for different segments
Inside OpenCart, we implemented price groups and markup rules tied to account type. Retail buyers see standard prices, small partners see distributor pricing, large wholesale buyers see their own conditions and minimum quantities. Rules determine which prices appear in the cart, which discounts apply, and which payment methods show up per group.
Custom storefront frontend
A fully custom design that serves both retail shoppers and wholesale buyers. The responsive layout puts collection showcases, large outerwear cards, season- and type-based filters, and a clear cart and checkout structure front and center. The design system supports future interface growth through reusable components.
Order processing
The integration module converts website orders into a structure the external system accepts — items, prices, discounts, buyer details, customer type. Each customer group follows its own flow. Retail buyers proceed to online payment. Distributors and wholesale partners submit orders that become invoices inside the ERP. The result flows back so warehouse and finance work from one consistent data set.
Content management
We extended OpenCart's defaults for the content team — separate fields for visual materials, collection blocks, promo banners, related-product recommendations. The marketing team can update storefronts without touching the ERP-driven import logic.
Infrastructure and performance
Catalog-page caching, dedicated database indexes for product filtering, and background jobs for imports and order exports — so integration processes never block the storefront for visitors.
We started by breaking the three sales channels down — retail, small partners, large wholesale. With the client, we compared how each segment currently places orders, what data is stored in the accounting system, and what needs to surface on the site. From there, we decided which parts could be unified and where the interfaces had to differ — minimum quantities, availability of specific product lines, different payment methods.
+5 Resource
The store became a working online-order mechanism for both retail customers and partners — and the manual bridge between the site and ERP disappeared. The design and UX now match the expectations of a fashion brand, not a template-based store.
