FLUF Connect

OpenCart vs WooCommerce: A Standalone Store or a Shop Inside WordPress?

How the two open-source shop platforms differ on cost, upkeep and add-ons, and what FLUF Connect can do with each when you add marketplaces.

Key Takeaways

  • OpenCart is a standalone shop you install on its own. WooCommerce is a plugin that turns a WordPress site into a shop.
  • Both are open source with no licence fee. OpenCart advertises “zero monthly fees” and WooCommerce “no platform fees, no revenue share”. You pay for hosting, payments and add-ons.
  • WooCommerce has the larger ecosystem, with 7+ million active installations. OpenCart is the lighter install if you do not want WordPress.
  • FLUF Connect links either store to marketplaces. Today it covers more of a WooCommerce catalogue than an OpenCart one.
  • FLUF Connect costs 7 days for £1, then from £9/month.

The difference in one paragraph

WooCommerce is a WordPress plugin. You cannot run it without a WordPress site underneath, and that shapes everything about it: the admin screens, the themes, the plugin directory, the update routine. OpenCart is a separate application whose only job is to be a shop. If you already run WordPress, WooCommerce adds a shop to the site you have. If you want a shop and nothing else, OpenCart gives you fewer moving parts.

This comparison is for small merchants choosing between the two, or sitting on one and wondering about the other. It is not for anyone who wants a hosted service with support on the phone. Both of these put the hosting, security and updates in your hands, unless you pay someone to take them.

Cost: neither is free to run

The software costs nothing in both cases. The bills come from everything around it.

Hosting. You rent a server for either one. WooCommerce asks more of it. Its requirements page sets a newer PHP version and a 256 MB memory limit, because the server is running WordPress and the shop together. OpenCart’s requirements are shorter. If you would rather not manage a server, OpenCart sells OpenCart Cloud, a hosted version with its own plans.

Payments. Neither platform takes a cut of sales. Your payment provider does. WooCommerce’s pricing page puts card processing at roughly 2.50% to 2.90% plus 30¢ per transaction with WooPayments, and adds no fee if you choose another processor. On OpenCart you pick a gateway from the marketplace and pay that gateway’s rate.

Add-ons. This is where budgets drift. A shop on either platform usually ends up with a paid theme and a handful of paid extensions. Here is a first-year sketch for a shop taking $20,000 in card payments, using WooCommerce’s published WooPayments range: between $500 and $580 in percentage fees, plus 30¢ for each order. The platform line on the same bill reads $0. An OpenCart shop using a gateway with similar rates would pay a similar amount, so the choice between the two rarely comes down to fees.

Setting up and running the shop

OpenCart installs as one application with one admin panel. Products, orders, customers, tax rules and coupons are all built in, and the screens do not change much between versions. People who find WordPress busy tend to like this.

WooCommerce inherits the WordPress admin. That is a strength if you also publish articles, run a membership or want a page builder, because one login covers the lot. It is a cost if you do not, because you are maintaining a content system you never asked for. WordPress, the theme, WooCommerce and every plugin update on their own schedules, and someone has to test the shop after each one.

Both handle size and colour choices, in different ways. WooCommerce calls them variable products: one product with a set of variations, each with its own price, stock and image. OpenCart attaches options to a product. This matters later if you connect marketplaces, because tools differ in which of the two they can read.

Extensions and help

WooCommerce is the bigger world. With more than seven million active installations, almost every payment provider, courier and accounting package publishes a WordPress plugin for it, and freelancers who know it are easy to hire. The core plugin’s support is the community forum.

OpenCart’s marketplace is smaller and still broad. OpenCart counts 13,000+ modules and themes covering payments, shipping, marketing and language packs. It offers community help or dedicated commercial support. Before you commit to OpenCart 4, check that the extensions you depend on have a version for it.

Which one should you pick?

  • Pick WooCommerce if you already have a WordPress site, if content and search traffic are part of how you sell, or if you want the widest choice of plugins and developers.
  • Pick OpenCart if you want a plain catalogue-and-checkout shop, prefer a single application to maintain, and do not need a blog engine behind it.
  • Pick neither if nobody on your team will handle updates and backups. A hosted platform will cost more per month and less in evenings.

Adding marketplaces to either store with FLUF Connect

A shop you own has no built-in audience. Marketplaces have the audience and charge for it. FLUF Connect links your store to eBay, Etsy, Vinted and the other 63 channels it supports, so one catalogue feeds all of them.

For a WooCommerce store, you install the FLUF Connect plugin for WooCommerce from your WordPress admin, under Plugins, the same way as any other WordPress plugin. Then you connect the store and choose which marketplaces to list on.

For OpenCart, you download the FLUF Connect extension from the OpenCart Marketplace, upload it under Extensions, then Installer, and enable it under Extensions, then Modules. The module shows a connection key, which you enter with your store address on the Channels screen in FLUF.

FLUF does not move a shop from one platform to the other. If your OpenCart catalogue is built on size and colour options, that is a reason to wait, or to favour WooCommerce if marketplace selling is central to your plans.
