Incremental, not big-bang
We replace legacy systems piece by piece, so the business keeps running and risk stays small at every step.
Backendz modernises legacy applications step by step: moving them to the cloud, upgrading old frameworks and rebuilding the parts holding you back, while your team keeps working. The result is software that's faster, safer and ready for AI.
Or see how we engage first — four shapes, no sales call required.
No more software only one retired contractor understands
Stop paying for servers in a cupboard that could fail any day
Forget frameworks that stopped getting security updates years ago
Done with database limits that halt the business without warning
Skip waiting weeks for changes that should take a day
Say bye to integrations that are impossible because there's no API
We replace legacy systems piece by piece, so the business keeps running and risk stays small at every step.
We've upgraded production databases, moved applications to the cloud and migrated live data between environments without stopping operations.
We recommend upgrading, re-platforming or rebuilding based on cost and risk, not on what's fashionable.
Clean data, modern APIs and cloud hosting, so you can add automation and AI next.

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.
Typical timeline: 2–4 weeks
Best for: businesses that know their system is a risk but not how big
Best for: businesses on ageing servers or expiring contracts
Best for: apps on unsupported .NET, PHP or database versions
Best for: core systems too risky to replace in one go
Every card is a build we shipped and still support. Open one for the decisions behind it.
What falls inside this service. Nothing here is an upsell discovered later.
We review the code, infrastructure, data and how the business depends on the system.




Operations directors, CTOs and plant managers — the ones still using the system a year after the invoice cleared.
Freight operator · 14 depots
Freight operator · 14 depotsWe 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.
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.
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.
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.
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 & CladdingThe 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.
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.
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.
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.
Our teams were entering the same information into several tools. Backendz mapped the process with us and built a more connected workflow with clear review points.
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.

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.
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.
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.
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.
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.
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.
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.
The engineers worked alongside our team and explained their decisions clearly. Code reviews and practical documentation helped us stay involved throughout delivery.

Book a callApplication modernisation is updating legacy software so it runs on current technology: moving it to the cloud, upgrading old frameworks and databases, or rebuilding parts of it. The goal is software that's more secure, faster to change, cheaper to run and able to connect with modern tools and AI.
It depends on the code's quality and how much it holds the business back. Many systems can be upgraded or moved to the cloud at far lower cost and risk than a rewrite. Backendz assesses the system first and recommends rebuilding only the parts where it pays.
Usually, yes. By modernising in stages, running old and new systems in parallel and planning each cut-over carefully, most migrations happen with little or no interruption to daily work.
An assessment typically takes 2 to 4 weeks. A cloud move or framework upgrade can take weeks; a gradual replacement of a core system usually runs over several months, delivered in stages.
The strangler-fig approach replaces a legacy system gradually: new features are built as separate modules alongside the old system, and users are moved across piece by piece until the old system can be switched off. It avoids the risk of a single big-bang replacement.
It lays the foundation. Modern APIs, clean and accessible data, and cloud hosting are what AI tools and automation need to connect to your systems. Many clients add AI features once modernisation is complete.
