What our clients say
Feedback from teams who trusted us with their most important digital asset.
"ThemeFlex rebuilt our entire agency site in six weeks. PageSpeed went from 54 to 98, enquiries doubled in the first month, and our team can update every section without touching code. The attention to detail is extraordinary."
"Our WooCommerce store migration was seamless — zero downtime, 40% faster checkout, and AOV up by a third within 90 days. The team understands both the technical and commercial side of e-commerce at a level I have never experienced before."
"Three years on retainer and they still treat every request with the same urgency as day one. The maintenance plan has kept us at 100% uptime through two major plugin conflicts that could have been devastating. Genuinely indispensable partners."
Frequently asked questions
Straight answers to the questions we hear most often.
A standard 5-page site takes 4–6 weeks from kickoff to launch. WooCommerce stores typically run 8–12 weeks depending on catalogue complexity. Enterprise rebuilds are scoped individually. All timelines include a 2-week buffer for feedback rounds — so the date we give you is the date you get your site.
Yes. We work with clients across Europe, North America, and Australia entirely remotely. Our project management tooling is async-first, and we schedule review calls to suit your timezone. English and German are both fully supported.
Absolutely. Every project includes a structured content editor training session and written documentation. We build with the WordPress block editor or Elementor so your team can update text, images, and layouts without touching code. If you hit a wall, our maintenance clients get priority support responses within 4 business hours.
Retainer plans cover weekly core, plugin, and theme updates tested in a staging environment before deployment; 24/7 uptime monitoring with SMS/email alerting; daily off-site encrypted backups with 30-day retention; malware scanning and firewall rule management; and up to 2 hours of content or minor development changes per month.
We provide fixed-price quotes based on a detailed scope document agreed before work begins. Pricing reflects design complexity, number of templates, third-party integrations, and post-launch support requirements. Change requests outside the agreed scope are quoted separately and require your written approval before we proceed — so there are never any surprise invoices.
