Custom Software
Development Company
Software built around the way your business actually works.
Skilserve is a London-based custom software development company. We design, build and support web platforms, mobile apps, integrations and AI-enabled tools that replace workarounds, unify your data and scale with you. You own the source code from day one.
Trusted by leading brands, public bodies and universities across 30+ countries
Powered by leading cloud and AI platforms
Compliance
From a first release to a platform running across teams, we cover the full lifecycle: discovery, design, engineering, testing, deployment and long-term support.
Off-the-shelf tools are the right call for standard problems. Custom software pays off when your processes are a competitive advantage, or when disconnected tools are costing you time and accuracy.
Fit to your workflow
The product adapts to you.
Long-Term Cost
You own the asset, no per-seat fees.
Integrations
Built to your system.
Ownership
You own code and IP.
Manual Work
Teams rely on spreadsheets and manual re-keying to bridge tools. Work
Slow Legacy Systems
Releases are slow because the legacy system is fragile. Modernize
Mismanagemnet
You pay for licences and modules you barely use. Scale
Disconnected Workflows
Customer or employee workflows span disconnected systems. Workflows
No Delivery Plan
An inherited product needs a clear delivery plan. Plan
Want An Extend
You want to add data, automation or AI to existing software. Extend
Not sure whether to build, extend or integrate?
Tell us what you need to run and we'll give you an honest recommendation, even when that's "don't build."
We validate scope and user experience early, then build and release in stages against clear acceptance criteria.
-
01
Discovery & Planning
We map workflows, users, systems and constraints, then define scope, priorities and success measures.
-
02
Architecture & Design
We plan the technical structure and design the UX around how your users actually work.
-
03
Agile Development
focused sprints with working increments, sprint reviews and a prioritised backlog you control.
-
04
Testing & Quality Assurance
Automated and manual testing, CI/CD, integration, performance and security checks before every release.
-
05
Launch & Ongoing Support
Controlled deployment, handover documentation and continued monitoring and improvement.
You should always know what’s being built, what it costs and who owns it
Scope Control
Requirements and acceptance criteria agreed before implementation.
Change Management
Impact on budget and timeline reviewed before new work is approved.
Visibility
Standups, sprint demos and shared working builds, so there are no surprises.
Documentation
Architecture, deployment and operating guides maintained throughout.
Ownership & Handover
Repository access, source code and knowledge transfer. Your agreement defines ownership, milestones and support.
Application Layer
Deliver workflows through web, mobile, portals, and APIs.
Business Logic
Build application services and rules around the work your team needs to complete.
Data layer
Connect databases, search and reporting with appropriate access and retention controls.
Integration layer
Connect ERP, CRM, identity, finance and operational systems through supported interfaces.
Validation
Check permissions, inputs, approvals and business rules before processing actions.
Monitoring
Track reliability, performance, errors and usage after release.
We choose tools for your requirements, maintainability and team skills, not a fixed preferred stack.

Modernisation Programme
Incremental migration of legacy systems and integrations without a risky rewrite.
What are custom software development services?
They cover discovery, UX design, architecture, development, testing, deployment and support, building software tailored to your workflows rather than adapting a generic product. You also receive documentation and handover for long-term ownership
How much does custom software development cost?
Cost depends on scope, integrations, user roles, security needs and design complexity. As a rough guide, a focused MVP or internal tool typically starts from £10,000–£50,000, a full business application from £50,000–£150,000, and complex platforms above that. We confirm a fixed or phased estimate after discovery.
How long does it take to build custom software?
Do you build both web and mobile apps?
Yes. We build web and mobile applications on shared APIs, which keeps data consistent across platforms.
Can you integrate with our existing tools?
Yes. We connect CRM, ERP, payments, analytics and other systems through APIs and governed sync rules.
Who owns the source code and IP?
You do. You get full access to repositories, source code and deployment assets, along with documentation and handover.
Can you modernise or take over an existing system?
Yes. We review the codebase and architecture first, then plan phased improvements or a rescue roadmap to reduce risk.
How do you manage scope changes?
Changes are logged in the backlog and assessed for priority and impact, so you see the effect on timeline and budget before any work starts.
Do you offer support after launch?
Yes: bug fixes, monitoring, security updates and continuous improvement, as monthly maintenance, a dedicated squad or time-andmaterials.
