FIG 03 · Why it matters
WooCommerce runs millions of stores. Plenty of them have outgrown their set-up.
From the WordPress.org plugin directory, W3Techs (22 Oct 2026) and php.net, read on 23 Oct 2026.
01
7+ million
Active WooCommerce installations
WordPress.org lists WooCommerce, “the open-source ecommerce platform for WordPress”, with 7+ million active installations. The current version is 11.2.1.
Source: WordPress.org, WooCommerce plugin page (23 Oct 2026)(opens in a new tab)02
11.5%
Of websites with a known CMS use WooCommerce
W3Techs: “WooCommerce is used by 11.5% of all the websites whose content management system we know”, which is 7.8% of all websites.
Source: W3Techs, WooCommerce (22 Oct 2026)(opens in a new tab)03
PHP 7.4+
The minimum is not the target
WooCommerce 11.2.1 needs WordPress 7.0+ and PHP 7.4+, but PHP 7 no longer gets security fixes and PHP 8.2’s security support ends on 31 Dec 2026 (php.net). We run stores on PHP 8.3 or later.

FIG 04 · Fit
Is WooCommerce right for you?
WooCommerce is the best fit when content and commerce live together and you want full control of the code and hosting. When you would rather not run anything, a hosted platform may suit you better. We build on all four.
| WooCommerce | Shopify | Magento | BigCommerce | |
|---|---|---|---|---|
| What it is | Open-source plugin for WordPress | Hosted platform | Open Source or Adobe Commerce software | Hosted platform |
| Hosting | Your choice of host | Hosted by Shopify | Your servers or Adobe’s cloud | Hosted by BigCommerce |
| Best for | Content-led stores and full control | Fast launch, low upkeep | Complex B2B and large catalogues | Mid-market and B2B on a hosted platform |
| Who keeps it updated | You or your agency | Shopify (apps and theme: you) | You or your agency | BigCommerce (apps and theme: you) |
| Our page | You are here | Shopify Plus development | Magento development | BigCommerce development |

FIG 06 · Speed and scale
How we speed up a slow WooCommerce store
Slow WooCommerce stores are rarely a WooCommerce problem. They are usually old order storage, no object cache, heavy plugins and unoptimised images. We measure, fix the biggest cause first and measure again.
1. Measure
- Check
- Core Web Vitals field data and slow database queries
- Output
- A ranked list of what is slowing the store
2. HPOS
- What
- High-performance order storage: orders in their own tables
- Why
- Faster order queries as order volume grows
3. Object cache
- Add
- Redis object caching and page caching that respects the cart
- Check
- Logged-in and checkout pages stay correct
4. Background jobs
- Fix
- A clogged Action Scheduler queue and heavy cron jobs
- Why
- Emails, syncs and renewals run on time
5. Images and plugins
- Images
- Modern formats, right sizes and a CDN
- Plugins
- Each one justified, or removed
6. Re-measure
- How
- The same tests on the same pages
- Then
- Speed checks in your monthly care plan

|---|---|---|
| WooCommerce core | The plugin itself: free and open source | No one |
| Hosting | Servers, backups, caching and a CDN | Your hosting company |
| Paid extensions | Subscriptions, bookings, shipping or other add-ons | Extension makers, usually yearly |
| Payment processing | Card and wallet fees on each order | Your payment provider |
| Design and build | Theme, custom features and integrations | Your agency, as a fixed quote |
| Maintenance | Updates, security, monitoring and fixes | Your agency or in-house team |
FIG 17 · Choose
How to choose a WooCommerce agency
Most “best WooCommerce agency” lists are written by an agency that ranks itself first. These are the questions we would ask any agency, including us.
| Ask | Why it matters | A good answer |
|---|---|---|
| Who owns the code and hosting? | You need to be able to leave | You do, from day one |
| How do you test updates? | Untested plugin updates break checkouts | On staging first, then live |
| Do you use HPOS? | Order storage affects speed at scale | Yes, checked with every plugin |
| How many plugins will we run? | Each one adds weight and risk | Only what the store needs |
| Are you a Woo Agency Partner? | Woo vets agencies for its partner programme | One signal among several; Elgrith is not one |
