What we build
Multi-tenant products with authentication, subscriptions and billing, role-based access, and the admin tooling a software business actually runs on. The plumbing that separates a product from a prototype.
Reporting dashboards, operations tools and internal apps that replace the spreadsheet everyone is afraid to touch. The fastest return on investment in software is usually an internal tool that removes a daily bottleneck.
Secure spaces where your customers log in to view, upload, pay or manage their account with you, cutting the email back-and-forth that eats your team's week.
Bespoke software shaped around your exact workflow when off-the-shelf tools force you to work their way instead of yours.
Connecting your systems to each other and to the outside world: payments, CRMs, ERPs, logistics, messaging and anything with an interface. We design APIs properly, because they outlive the interfaces built on them.
Where custom web apps change the business
The pattern behind every good custom build is the same: a workflow that matters, handled badly by spreadsheets, email or a tool that almost fits. How that looks by sector:
SaaS founders and product companies. The product itself: multi-tenant platforms with billing, roles and admin tooling, built to survive due diligence from investors and enterprise buyers. We are building our own SaaS products alongside client work, so the trade-offs are ones we live with personally.
Professional services. Client portals for documents, approvals, payments and case tracking, replacing the email threads that currently hold the firm together. The measurable win is hours of admin returned to billable work every week.
Operations-heavy businesses. Manufacturing, logistics, wholesale and property, where one internal tool that mirrors the real workflow replaces the spreadsheet nobody dares reorganise. This is consistently the fastest payback in custom software.
E-commerce operators. The systems behind the storefront: inventory across channels, order routing, supplier dashboards and reporting. We run our own stores, so we build these tools the way operators need them at 6pm on a Friday, not the way they demo on a Tuesday.
Organisations with legacy web systems. The internal platform built years ago that everyone depends on and nobody can safely change. We audit, stabilise and modernise in stages, without stopping the business to do it.
Healthcare, finance and regulated sectors. Workflow and data tools where compliance shapes the architecture: access control, audit trails, data residency and retention designed in from the first diagram, which as an Irish company under GDPR is our default posture anyway.
Web app, website, or off-the-shelf tool?
Three different purchases, often confused, so here is the plain version. A website presents information; if that is the need, our web development team builds it on the right platform for far less than custom development. An off-the-shelf tool makes sense when your workflow is common and a subscription product already fits; we will say so when it does. A custom web app earns its cost when the workflow is yours alone, when the tool must integrate deeply with your systems, when per-seat subscription pricing would scale painfully, or when the product itself is the business. Getting this decision right is worth more than any discount, and it is the first thing we help you settle honestly.
Built to maintain, not to replace
Plenty of agencies ship something that works on launch day and becomes unmanageable within a year. The pattern is always the same: no tests, no documentation, exotic stack choices, and a team that vanished. We build the opposite way: stable, widely supported frameworks, automated tests around the parts that matter, documentation as we go, and architecture a new developer can navigate. You own the full codebase, and it stays healthy whether we maintain it or your own team does. The best proof of confidence an agency can offer is code the client could walk away with.

What a web app costs, honestly
Industry-wide, focused internal tools and portals typically start around the low tens of thousands of euro or dollars. SaaS platforms with billing, multi-tenancy and admin tooling run higher, and complex products higher again. Beyond the build, budget for hosting and maintenance; a well-architected app keeps those modest. Custom software is an investment case, not a price tag: the question is what the manual work, the subscription stack or the lost deals currently cost you per year. We help you make that comparison honestly during discovery, and if the numbers do not justify a custom build, we will tell you before you spend, not after.
Ways to work with us
Discovery through launch for a defined scope, timeline and fixed price. The standard path for portals, tools and first product versions.
For larger systems, we ship in phases so real value lands early and each stage funds confidence in the next, rather than everything arriving in one distant big bang.
For SaaS founders: build, launch, then iterate continuously on a monthly cadence as real usage teaches you what the product actually is.
Audit of an existing system, a straight report on its condition, then stabilisation and staged improvement without interrupting the business.
Our engineers alongside your existing team, adding backend depth in Laravel, Django, .NET or Java where you need it.
Security and reliability come standard
Business software holds business data, so security is not an upgrade tier. Every build includes proper authentication, role-based access, encryption in transit and at rest, input validation, dependency updates and backups. As an Irish-registered company, we design for GDPR by default: data residency, retention and the rights of your users are architecture questions we settle at the start. Reliability gets the same treatment: monitoring, error tracking and sensible failure behaviour, so problems announce themselves to us before they announce themselves to your customers.
Technologies we work with
Laravel and modern PHP, Django and Python, and .NET or Java where the environment calls for it, which covers most serious backend territory. React and Next.js with TypeScript on the front end. PostgreSQL and MySQL. REST and GraphQL APIs. Cloud hosting on AWS, GCP or Azure with proper CI/CD and automated testing. We choose per project and explain the choice; the stack serves the product, never the other way around.
Why Raydiant Webs for web apps
Backend depth is the difference. Our team has built systems across Java, .NET, Python and PHP, including Oracle-backed enterprise platforms, and that experience shows up exactly where web apps usually fail: data modelling, integrations, performance under load and security. We also operate our own software, running e-commerce operations and building our own SaaS products, so we feel the consequences of architecture decisions the way you will. And we work honestly, including telling you when a platform or an off-the-shelf tool beats a custom build.
Web App FAQ
A website presents information. A web app lets people do things: log in, manage data, transact, collaborate. If your users need accounts and workflows, you need a web app.
Yes, including multi-tenancy, subscriptions and billing, role-based access and admin tooling, taken from idea through launch and beyond.
Focused tools and portals typically start in the low tens of thousands, with SaaS platforms and complex products above that. You get honest ranges before discovery and a fixed scope and price after it.
A focused first version typically takes a small number of months. Larger platforms take longer, and we phase them so value ships early rather than everything arriving at the end.
Completely. Full codebase, documentation and infrastructure access are yours, whether or not we continue maintaining it.
Often, yes. We audit the codebase first and give you a straight assessment of its condition and the sensible path: improve, refactor gradually, or in rare cases rebuild.
Yes. We set up proper hosting with monitoring and backups, and offer ongoing maintenance covering updates, security and improvements.
