Why build web app development with us?

Built for daily use

Our own platforms are used every day by operations teams, so we design for speed, clarity and the tenth time someone does a task, not just the first.

Architecture that scales

Multi-tenant design, background jobs and proper hosting from the start, so growth doesn't force a rebuild.

Security as standard

Role-based access, audit logs, encrypted data and UK GDPR controls in every build.

We stay after launch

Hosting, monitoring and ongoing development from the team that built it.

How we engage

Four ways this usually starts

Most enquiries land in one of these. If yours does not, say so on the call — we would rather shape the engagement than sell you the nearest shape we have.

The people who have to live with what we build

Operations directors, CTOs and plant managers — the ones still using the system a year after the invoice cleared.

We wanted answers our team could check against the original document. Having the relevant clause beside the response makes the assistant useful when reviewing policies and contracts.
Emma CollinsHead of Business Operations at Clearbrook Advisory
We needed scheduling, availability and shift changes in one place. Backendz shaped the system around the way our operations team works and stayed involved after launch to help us refine it.
James CarterOperations Director at Northbridge Facilities
Our rental journey had to work for both vehicle owners and travellers. Backendz brought listings, availability and bookings together into a platform that feels straightforward to use.

We wanted a practical way to review PPE and safety-zone events using our existing cameras. The team focused on the situations our site managers need to investigate and made the footage easier to review.
Daniel BrooksSite Operations Manager at Oakmere Construction
A single headcount does not tell us where congestion is developing. The zone-based view gives our team a clearer picture of how people are moving and where attention may be needed.
Olivia ReedVenue Operations Director at Cedarhall Events
The priority was a counting workflow our warehouse team could use during a normal shift. Backendz connected image-based counts with the records we already use and made discrepancies easier to review.
Michael TurnerWarehouse Manager at Harbourline Logistics
Tender preparation involves gathering evidence and getting the right people to review each section. Backendz brought those steps into one workspace, with drafts our team can check and approve.
William ParkerBid Manager at Westhaven Technical Services
Our information was spread across several operational systems. Backendz designed a clearer way to ask questions, inspect the supporting evidence and keep approval with our team before an action is taken.
Charlotte HayesChief Operating Officer at Elmbridge Services Group
Our estimating process needed to reflect how we actually price work. Backendz took time to understand the inputs and rules, then built a quoting journey our team could review and refine.
Thomas MitchellManaging Director at Ridgewell Roofing & Cladding
The reconciliation workflow gives our finance team one place to review mismatches and supporting records. We can trace an exception back to its source and decide what needs attention.
Henry WilsonFinance Director at Ashford Distribution
The team took time to understand how our staff work between appointments. The resulting system brings scheduling and client information together without making the day more complicated.
Amelia FosterHead of Operations at Meadowcrest Care
We had outgrown the spreadsheets that held our pricing rules. Backendz helped turn that knowledge into a quoting tool we can maintain and explain to new colleagues.
George EvansManaging Director at Stonefield Fabrication
We could review working features throughout the build and give specific feedback. That made it easier to keep the product focused on the people using it.
Isabel MorganProduct Director at Brightpath Learning
Connecting our sales and inventory systems was the priority. The integration gives our team a clearer view of updates and a practical way to investigate records that need review.
Jack HarrisonTechnology Manager at Westbrook Retail
Our field team needed access to job details away from the office. The mobile workflow keeps the relevant information close at hand and gives the office a clearer view of progress.
Grace PhillipsOperations Lead at Alderway Field Services
The cloud work started with understanding our existing systems and dependencies. The team documented the setup and gave us a clearer basis for monitoring and ongoing maintenance.
Oscar BennettIT Director at Brookvale Manufacturing
We wanted a client portal that reflected how we deliver our services. Backendz brought documents, requests and progress updates into a straightforward experience for clients and staff.
Lily ThompsonCommercial Director at Willowbank Consulting
The engineers worked alongside our team and explained their decisions clearly. Code reviews and practical documentation helped us stay involved throughout delivery.

FAQ

The things people ask before they commit.

Still have questions?

Ask it on the call. We would rather answer an awkward question early than discover it in month three.

Book a call
What is a web app?

A web app is software that runs in a web browser, so users don't need to install anything. Unlike a website, which mainly displays information, a web app lets people log in and do things: manage orders, update records, view dashboards or collaborate. Customer portals and SaaS platforms are web apps.

What is the difference between a website and a web app?

A website mainly presents information to visitors. A web app is interactive software with user accounts, data and workflows, such as a booking system or client portal. Many businesses have both: a marketing website and a web app behind a login.

How much does web app development cost?

Cost depends on the number of users, features and integrations. A focused portal or internal tool costs far less than a multi-tenant SaaS platform. Backendz fixes the scope and price for each release after discovery.

How long does it take to build a web app?

A focused web app or portal typically takes 8 to 12 weeks to a first release. Larger platforms are delivered in stages, with working software at every stage.

Will our web app work on mobile?

Yes. Every web app is built to be responsive, so it works on phones, tablets and desktops. Where your users need offline access, camera or push notifications, a progressive web app or a native mobile app may be the better fit.

Do you host and maintain web apps?

Yes. Backendz can host your web app on secure cloud infrastructure, monitor it around the clock and provide ongoing development and support. You can also host it yourself; the code is yours.
