WordPress Development That Means Business

WordPress runs a large share of the web, and for good reason: it is flexible, well supported, and easy for your team to update. But a business site is more than a theme and a few plugins. At Tec Dynamics we have built and maintained WordPress and WooCommerce sites for companies across England since 2015, and we treat them like the business systems they are: fast, secure, and properly integrated with the rest of your tools.

Whether you need a brand-new marketing site, a custom WooCommerce store, a bespoke plugin, or a rescue job on a site someone else left in a mess, we can help. And because we also build ERP integrations, we can connect your WordPress site to Entersoft, SAP, Sage or Dynamics so your products, stock and orders stay in sync automatically.

Our WordPress Development Services

Custom Theme Development

We build custom WordPress themes from your design or ours, coded to WordPress standards so they are fast, accessible and easy to edit. No bloated page-builder templates that slow the site to a crawl unless you specifically want one.

Bespoke Plugin Development

When an off-the-shelf plugin does not exist, or the one you have is fragile, we build a custom plugin that does exactly what you need. We have shipped production plugins that sync catalogues, connect WordPress to ERP systems, and add bespoke back-office workflows. You own the code.

WooCommerce Store Development

Full WooCommerce builds for B2C and B2B: custom checkout flows, customer-specific pricing, subscriptions, and payment and delivery integrations. We tune WooCommerce for speed so a large catalogue does not mean a slow shop.

ERP & System Integration

We connect WordPress and WooCommerce to ERP, CRM and accounting systems so data flows automatically. Products, stock, pricing and orders sync between your shop and your ERP, which removes manual data entry and prevents overselling.

Speed, Security & Maintenance

Core Web Vitals optimisation, caching, image handling and database cleanup to make the site fast, plus hardening, firewalls, backups and managed updates to keep it safe. We offer ongoing care plans so you are never left on an out-of-date, unpatched site.

Migration & Rescue

Moving to WordPress from another platform, or taking over a site built by someone else? We migrate content, preserve your SEO with proper redirects, and fix the theme, plugins and hosting problems left behind, then give you a clear plan going forward.

Why Tec Dynamics for WordPress

Plenty of agencies can install a theme. Fewer can also write a proper plugin, connect your shop to an ERP, and keep the whole thing fast and secure for years. We are a UK software company, not a template shop, so WordPress work sits alongside our bespoke software, mobile and integration teams. That means your WordPress site can grow with your business rather than boxing you in.
