[ ECONOMICS AND SCALE OF COMMODITY BUSINESS ]

Why OpenCart remains the leader for e-commerce sites with a large product range

Powerful combination of low ownership cost and high order processing speed

[ 01 ]

Instant filtering of thousands of characteristics and attributes

Thanks to optimization of MySQL indexes and implementation of smart cache modules (Turbo/JetCache) filtering by dozens of parameters works without page reload.

[ 02 ]

Increase conversion thanks to One-Page Checkout

Replacing the standard 6-step order placement formatting in OpenCart with an ergonomic one-page checkout reduces the percentage of abandoned carts by 25–35%.

[ 03 ]

Automatic order and inventory exchange

Full automation with 1C:Enterprise, BAS, Torgsoft, and warehouse systems, plus feed exports to Rozetka, Prom, and Google Shopping marketplaces.

[ 04 ]

Minimum server maintenance cost

A shop on OpenCart with tens of thousands of products is stably running even on an inexpensive VPS server, where heavy analogs would have required dedicated servers.

[ FREQUENT QUESTIONS ]

Answers to common questions from customers

Key details regarding terms, independent website editing, and rights transfer.

OpenCart was initially designed purely as an e-commerce engine with a proper relational database. Unlike WooCommerce (where products are stored in a general posts table wp_posts), OpenCart is able to quickly filter and sort catalogs on 50 000–100 000 products without performance degradation. In addition, OpenCart does not require monthly subscription fees in currency, like Shopify, and easily integrates with Ukrainian services.

We use tested and most stable releases of ocStore 3.0 / OpenCart 3.0 with long-term support. This branch has the greatest compatibility with Ukrainian banking modules, delivery services and excludes bugs of raw new versions.

We do not use heavy template filters that make 50 queries to the database for each click. We configure fast cached filter modules (OCFilter) with generation of correct SEO landing pages for each filter, which provides a massive increase in organic traffic from Google.

Yes. The delivery module automatically generates a delivery note in Nova Poshta cabinet with 1 click, and after the order status changes, the customer instantly receives the TTN number via SMS, Viber or Telegram through integrated mailing services (TurboSMS / AlphaSMS).

Yes, we provide an official warranty from 60 to 90 days on all completed work. If any discrepancy with the approved SRS or code error is found, we fix it free of charge and promptly.
