Testimonials
What Our Clients Say About Working With Us
★★★★★
Fast, calm and on time. The store has not skipped a beat since.
OwnerTractor & farm equipment care retailer ★★★★★
Our gift season used to break the site. It no longer does, and the bundle builder alone paid for the work in the first December. Support through the peak was quick and unflustered, which mattered more than anything on the proposal.
FounderOnline chocolate gift basket retailer ★★★★★
Subscriptions finally work the way our customers actually buy.
eCommerce ManagerDog nutrition & supplement brand ★★★★★
The morning check-in message was a small idea that changed our retention. Members who complete yesterday's session now start today's. We asked for an app and got a coach in people's pockets.
Head TrainerGym & personal training business ★★★★★
WebCentauri Technologies understood our vision and delivered more than we expected. The platform is fast, user-friendly and our customers love the experience. Their professionalism and support throughout the project were outstanding.
Jessica WilliamsFounder, ShopEase★★★★★
Beautiful on a phone, which is where most of our visitors are.
Marketing ManagerHomeNest ★★★★★
Planning used to take three hours a shift and a lot of phone calls. The dispatch board replaced all of it, and our customers hear about a delay before they think to ask. Drivers took to it in a day, which told me the screens had been designed around them rather than around us.
Operations DirectorRegional freight & courier operator ★★★★★
Four seconds to under one, and organic traffic followed.
Head of DigitalIndependent financial advisory firm ★★★★★
Live availability on every itinerary ended the double-bookings that used to cost us a few thousand a season. Customers book a deposit at midnight now, which is precisely when they were previously sending us an email we would answer two days later.
Operations ManagerAdventure tour operator ★★★★★
Two hundred handlers moved from three systems to one screen. Handling time fell from five days to just over three.
Head of ClaimsCommercial insurance broker ★★★★★
They cut our JavaScript by two thirds and our recipe pages now load in about a second on a phone. Rich results came back within weeks. For a publisher living on organic traffic, that is the whole business.
EditorIndependent food magazine ★★★★★
Repairs get fixed nine days faster and tenants stopped ringing the office to ask.
Lettings DirectorResidential property management company ★★★★★
Three of my team spent most of the week typing invoices. Now 93% post themselves and the rest come to a review screen that takes seconds. Month end closed four days earlier than it ever had.
Practice PartnerAccountancy practice ★★★★★
Stock went from a day out of date to seconds. Oversells simply stopped.
Supply Chain ManagerIndustrial equipment manufacturer ★★★★★
They asked better questions than the two agencies we spoke to before. The scheduling system fits how nine clinics actually work, not how software wishes they worked. No-shows are down 42% and our utilisation report finally means something.
Practice ManagerMulti-site physiotherapy clinic group ★★★★★
Ten weeks of runway, one workflow, paying customers at the end of it.
Co-founderField-service software startup ★★★★★
Eleven thousand people bidding at once and nobody seeing a stale price. Our auctioneers trust the screen in front of them again, and the bid history has settled two disputes that would previously have gone to a solicitor.
Saleroom DirectorFine art & collectibles auction house ★★★★★
Eighty-four thousand parts, every trade account on its own pricing, and stock that matches the ERP. Around 60% of our order lines moved off the phone within a quarter.
Managing DirectorIndustrial parts distributor ★★★★★
Six thousand pages, a hundred and forty editors, three languages. The migration was boring, which was the point.
Digital LeadUniversity faculty of science ★★★★★
Nine practice websites became one and each practice still ranks in its own town. Every old URL was mapped before launch, so we never saw the dip everyone warned us about. We also stopped paying nine separate subscriptions, which the board noticed.
Marketing ManagerMulti-practice dental group ★★★★★
Our crews work where there is no signal. The app does not care.
Operations LeadUtility inspection contractor ★★★★
Stock used to be a day old and orders were re-typed twice. The integration ended both. It ran a fortnight longer than planned, but they were straight with us about why, and the replay screen means our team fixes a stuck message without calling anyone.
IT ManagerWholesale building supplies distributor ★★★★★
Paper stamp cards are gone and the morning queue has thinned out.
Retail DirectorSpeciality coffee chain ★★★★★
Our pickers work in parts of the warehouse where Wi-Fi does not reach. The app never notices. Eleven seconds a line, mis-picks caught at the shelf rather than at dispatch, and no more paper.
Operations ManagerThird-party logistics provider ★★★★★
Guests walk past reception and unlock the room from their phone.
General ManagerBoutique hotel group ★★★★★
Sharing the assessment rules between Android and iOS ended a class of bug we had lived with for years. The two apps cannot disagree now, and a rule change reaches both in the same week instead of three apart.
Mobile LeadRegional insurance group ★★★★★
Seven weeks from our existing Angular system to both app stores. Carers log visits at the door and the funder evidence writes itself.
Service ManagerHome healthcare provider ★★★★★
Deployments take four minutes and the hosting bill halved.
Head of TechnologyVideo learning platform ★★★★★
We were about to buy a seventh database server. They profiled the actual queries instead and we went down to two. Search went from two and a half seconds to under fifty milliseconds at twice the traffic. That conversation paid for the engagement several times over.
CTOPeer-to-peer rental marketplace ★★★★★
What sold us was that it says when it does not know.
Support LeadB2B software vendor ★★★★★
Selling plants online is awkward — seasons, lead times, couriers that lose a weekend. They built those rules into the store rather than leaving them in our heads, and the refunds for dead arrivals fell away almost immediately.
OwnerPlant nursery & garden centre ★★★★★
The club runs itself now. Gifting became a real product line at Christmas.
FounderIndependent craft brewery ★★★★★
They rebuilt the product page around subscriptions instead of bolting another app on top, and removed six apps that were slowing the store down. Repeat orders are the majority of our revenue for the first time.
eCommerce ManagerSports nutrition brand ★★★★★
Every watch is unique, which breaks most themes. Not this one.
DirectorPre-owned luxury watch dealer ★★★★★
Framework pricing, spend limits and approvals all inside the store. Our clinical customers reorder in a couple of clicks and our account managers went back to answering clinical questions instead of typing orders.
Sales DirectorMedical & care supplies distributor ★★★★★
Eleven thousand products off an unsupported platform in one night, with the delivery slots our customers actually needed. Checkout completion improved 26% and traffic recovered inside three weeks.
Head of eCommerceMulti-brand furniture retailer ★★★★★
Menu changes publish in minutes. Allergens are finally consistent.
Group Operations ManagerSeven-restaurant hospitality group ★★★★
Bringing donations back onto our own site lifted completion straight away, and Gift Aid is now captured digitally at the point of giving rather than on paper we had to chase. Our fundraisers build campaign pages themselves in an afternoon.
Marketing DirectorRegional charitable trust ★★★★★
Certificates issue themselves the moment a learner passes, with a code employers can verify. That removed most of a part-time admin role and the renewal reminders turned lapsed customers into repeat revenue.
Training DirectorHealth & safety training provider ★★★★★
Engineers find the right valve in seconds instead of comparing PDFs.
Sales DirectorIndustrial valve manufacturer ★★★★★
Five languages, one structure, each market ranking in its own language. Our regional teams keep their own contacts and references up to date without anyone breaking the brand template.
Export ManagerMachinery exporter ★★★★★
New instructions appear on the site within minutes of being listed.
Branch PartnerRegional estate agency ★★★★
Couriers can see what they have earned during the shift, not a week later. Retention improved, which was the number we actually cared about. Customers stopped calling to ask where their order was, which was the number our support team cared about.
Fleet ManagerCity food delivery operator ★★★★★
Members freeze a card at two in the morning without calling us.
Chief ExecutiveMember-owned credit union ★★★★★
Consent forms come back the same day now. Anyone who has chased a school trip letter around fourteen schools will understand what that is worth. Parents with children at two of our schools see everything in one place, which was the request we could never fulfil before.
Trust Operations LeadMulti-academy school trust ★★★★★
Consultations start on time because the app tests the connection first.
Clinical Services ManagerPrivate healthcare group ★★★★★
Twenty-five thousand scans an hour with no dependence on venue Wi-Fi. The first festival we ran with it was the calmest gate we have had, and the live throughput view let us move stewards before a queue formed rather than after.
Event Operations DirectorLive events & festival operator ★★★★★
Customers walk from the terminal straight to the car.
Regional ManagerAirport car rental operator ★★★★★
The guided damage photos ended most of our disputes. We expected the keyless entry to be the headline and it turned out the boring evidence trail was worth more.
Claims HandlerAirport car rental operator ★★★★★
They told us we did not need Kubernetes for our traffic. A less honest agency would have taken the budget and built it anyway. We have used them for three projects since.

FAQ
Frequently Asked Questions About Our Web & App Development Services
What types of websites and apps does WebCentauri build?
We build business and corporate websites, custom web applications, client portals, WordPress websites, eCommerce stores on Shopify, WooCommerce and BigCommerce, and mobile apps for Android and iPhone. We also improve, fix and maintain existing websites and apps.
Do you develop mobile apps for Android and iPhone?
Yes. We build cross-platform apps with Flutter and Dart that run natively on both Android and iOS from one codebase, as well as fully native apps in Kotlin and Swift. We handle UI/UX design, backend APIs, and publishing on Google Play and the Apple App Store.
How much does a website cost?
Cost depends on the number of pages, features, integrations and design complexity. After a free consultation we provide a fixed, itemised quote, so you know the investment before any work begins.
Will my website be optimised for search engines?
Yes. Every site we build uses semantic HTML, a logical heading hierarchy, descriptive metadata, structured data, XML sitemaps and fast load times — the technical foundations search engines need to crawl and rank your pages.
Do you offer support after the website launches?
Yes. We offer flexible monthly maintenance and support covering updates, security monitoring, backups, performance checks and content changes.
Can you work on my existing website?
Absolutely. We regularly take over existing WordPress, WooCommerce, Shopify and custom PHP websites to fix bugs, add features, improve speed or redesign them.
