01
Data lives in separate files
Spreadsheets work until versions diverge, information is duplicated and nobody is certain which file is current.
Custom web applicationsPortals · tools · calculators
When a website is not enough, build the tool.
A custom web application handles the work a presentation website cannot: user accounts, registrations, calculations, records and repeatable business processes. We design it around the way your company actually operates.

Process overview
One source of truth
Live data, clear permissions and a process your team can follow.
Users
Role-based access
Each person sees the right information.
Output
Automated results
Calculations and documents without retyping.
When a website stops being enough
A website explains the offer. An application helps deliver it.
A business website should build trust and guide people towards contact. When the work after that contact needs to be processed, calculated, scheduled or recorded, the business needs a tool rather than another page.
02
Different users need different access
Clients, members or employees need a private view of the data and actions relevant to them.
03
The same calculations are repeated
Quotes, budgets and estimates are rebuilt manually even though the logic is largely the same every time.
04
The process exists only in people’s heads
Growth, absence or staff changes expose how much knowledge depends on a few individuals.
Website vs web application
The difference is not the size. It is the job.
The two often work together: the website creates understanding and demand; the application supports the work that follows.
Website
Presents and persuades
Explains the offer, builds confidence and guides a prospective customer towards the right next step. Most visitors see the same content.
Web application
Processes and performs
Authenticates users, stores data, calculates results, generates outputs and moves work through a defined process.
What we build
Custom applications built around a specific business problem.
We begin with the work that causes delay, duplication or errors. Only then do we define the screens, roles, data and first-release scope.
Client portals & registrations
Registration, sign-in and a private dashboard for clients, members, employees or event participants.
Discuss a portal →Quote generators & calculators
Turn structured inputs into a result, estimate, budget or document that is consistent and ready to use.
Scope a calculator →Scheduling & planning tools
Bring shifts, appointments, availability and changes into one current view for the whole team.
Improve planning →Internal records & workflows
Organise jobs, assets, reports or operational records that currently live across disconnected spreadsheets.
Discuss an internal tool →
Representative application work
Systems created for real operational needs.
Each project starts with a concrete task that should be clearer, faster or less dependent on manual handling.
Sports club registration portal
User accounts, registrations and private information for participants, with the supporting administration in one place.
Quote generation tool
A structured process that turns a small set of inputs into a consistent commercial quotation without repeated copying.
Shift planning system
A shared schedule showing who is working, what changed and what the team needs to know without circulating spreadsheets.
Budget calculators
Rule-based calculators that show the result immediately and make the underlying calculation repeatable and auditable.
How collaboration works
From a process on paper to a working application.
Custom software should not begin with an open-ended build. We define the problem, users and first-release scope before development starts.
01
Discovery and analysis
We map how the process works today, who is involved and where time, errors or uncertainty accumulate.
02
Scope and architecture
We define screens, data logic, user roles and what belongs in the first release versus a later phase.
03
Development and testing
The application is built and reviewed in stages so important decisions are made before the final release.
04
Launch and support
We deploy, hand over and agree how ongoing maintenance, support and future improvements will be handled.
Pricing
A custom application has a defined scope, not a generic package.
Two projects with the same label can require very different amounts of work. We price the project after discovery and provide a clear scope before development begins.
01
Screens and logic
The number of views, the actions within them and the business rules behind each result.
02
Users and permissions
Whether the system has one user type or several roles with different data and capabilities.
03
Data and integrations
Existing data, imports, exports, documents, payments or connections to other systems.
04
Post-launch operation
Whether your team takes ownership or VERLYON provides agreed maintenance, support and further development.
The initial consultation is free and without obligation. If a custom application is not the sensible solution, we will say so and recommend a simpler route where possible.
Web, mobile and PWA
Our main focus is browser-based web applications.
A web application runs in a browser on desktop and mobile, requires no app-store installation and can be updated centrally. For many business projects, that is the most efficient starting point.
Primary capability
Responsive web applications
Client portals, calculators, planning tools and internal systems designed to work cleanly across desktop and mobile browsers.
When the brief requires it
Native mobile and PWA
Considered after consultation. We first verify whether a native iOS or Android application creates enough value to justify the additional complexity.
Free initial consultation
Describe the process that slows your business down.
You do not need a feature list or technical specification. Tell us what happens today, who is involved and where the manual work begins. We will help determine whether a custom application is the right next step.
A useful first brief includes:
- how the process works today,
- who needs to use the system,
- what information goes in and what should come out.
Frequently asked questions
Before custom application development begins.
No. Describe how the process works today and what causes delay or errors. We will propose the screens, logic and sensible first-release scope before development begins.
A website explains an offer and guides people towards contact. A web application performs work: it can authenticate users, store data, calculate results, generate outputs and manage a process.
Pricing depends on the number and complexity of screens, user roles, data, integrations and post-launch requirements. We define a clear scope and project price after the initial consultation.
Yes. Projects can include registration, sign-in, user roles, permissions and private views so each person sees only the information relevant to them.
The operating model is agreed before launch. Your team can take ownership, or VERLYON can provide ongoing maintenance, technical support and further development under a separate scope.
