Posudmeister OpenCart Migration Case Study

Client

Posudmeister is a Ukrainian online store selling cookware, kitchenware, tableware, gifts and home goods. Its customers include retail shoppers, regular customers with personal discounts and HoReCa businesses that value a wide assortment, repeat orders and payment by bank transfer. The site ran on an outdated version of OpenCart 1.5, and the catalog contained more than 2,000 SKUs.

Challenges

The store had to be moved to a modern platform without losing data or search rankings: the catalog, customer base and order history. At the same time, the business wanted a new design, a more convenient checkout, flexible promotions and stable data exchange with its accounting systems.

The site had to work equally well for retail shoppers and gift seekers, for regular customers with a cumulative discount, and for restaurants, cafes and hotels that buy in bulk.

Lossless migration: more than 2,000 SKUs, customers, addresses and order history.
Preserving SEO rankings: page URLs, metadata and 301 redirects.
Flexible promotions: promo codes, private sales, gifts, order-total discounts and a loyalty program.
Checkout for B2C and B2B: multiple delivery options, online payment, installment payments and payment by IBAN bank details.
Automated accounting: data exchange with 1C and two-way synchronization with KeyCRM.

Solution

Audit and migration. We analyzed the old site's structure, catalog size, customer data, custom modifications and migration risks. We then moved the catalog, attributes, options, manufacturers, customers and orders to OpenCart 3.0.4.1 while preserving the image structure, installed SEO Pro and set up 301 redirects.
A catalog built for a large assortment. Three category levels, filters by price, color, volume, size and manufacturer, and fast, typo-tolerant AJAX search by name and SKU. The interface is available in Ukrainian, English and Russian.
Promotions with compatibility rules. Promo codes, private VIP sales, gifts with a product and for an order total, order-total discounts, cumulative discount tiers and a promotion compatibility table. Separately, gift certificates with a unique code sent by email.
One-page checkout. Nova Poshta, in-store pickup and the store's own courier delivery; LiqPay, MonoPay, WayForPay, Apple Pay, Google Pay, installment payments, IBAN for B2B, packaging and a discount for online payment. The customer account shows the individual discount, order history, electronic receipt and a reorder option.
Accounting integrations. Daily synchronization with 1C: products, prices, stock by warehouse and availability. KeyCRM receives orders with actual prices, discounts and gifts and sends order and payment statuses back to the site.
