Choosing
What should you build first?
Start with the way people will use the product. A web app fits work done at a desk or shared through a link. A mobile app is a stronger starting point when the product centres on the camera, location or daily notifications. That choice shapes which screens and interactions need attention first.
For a web app with a rich interface, Next.js and React with TypeScript offer a way to use the same language across the front end and back end. We build with TypeScript across the application, using a stack such as Next.js, React, Node.js and PostgreSQL. If your existing team works in PHP, Ruby or Python, Laravel, Rails or Django are options worth considering.
Hosting is a separate decision. Managed platforms such as Vercel, Supabase or Firebase reduce setup and server upkeep. Direct hosting on AWS or Google Cloud offers more control and can cost less at scale, with more operations work. We help you choose by turning your idea into a feature list and agreeing what the first version needs.

What London organisations need from a web app
Technology companies in East London Tech City launching a SaaS product need a focused first version with accounts and billing. For their customers, the first screens also need to make the product usable: sample data and clear empty states give a new user somewhere to start.
In London’s financial centre, a firm moving work out of spreadsheets and inboxes may need shared data, permissions and a history of activity. If its product serves several companies, workspaces and roles must keep each customer’s data separate from the others.
London’s universities and colleges may also have repeatable services they want to deliver through software. Client logins and subscriptions can turn those services into workflows, while an admin dashboard gives the team a way to check accounts and answer support questions.
Rules
What the UK project needs to handle
A service delivered through a website needs reasonable adjustments for disabled people. We design the app’s screens with access in mind and refine them with your feedback as the product takes shape.
For cookies used solely for statistics or to adapt appearance to user preferences, the UK rules allow use without consent when users receive clear information and an easy way to object. We set up that information and objection route when those cookies are part of the build.
How it runs
How a project runs with us
We work remotely over video calls, WhatsApp and shared project boards. India is 5h30m ahead of the UK, or 4h30m ahead during British Summer Time, so the shared board keeps decisions and feedback available across the time difference.
- 01
Discover
We turn your idea into a feature list and agree what the first version needs. You help us identify the work users must be able to complete.
- 02
Design
We create desktop and mobile screen designs before coding starts. You review the flows and give feedback so we can refine them.
- 03
Build
Each increment goes to a staging site. You try real tasks there and approve changes before they reach your users.
- 04
Test with users
A private beta gives a small group of target users the product before public launch. Their feedback exposes confusing steps and missing features while changes are still cheaper to make.
- 05
Launch
We set up deployment, error tracking and backups before the product goes live. You can review the launch setup with us as the build approaches release.
Checklist
What to have ready before we talk
Bring whatever you already have, including any open questions.
- Current toolsNote the competitors or tools users piece together and what is missing from each.
- Pricing modelConsider per-seat, usage-based or flat plans; the choice affects billing and permissions.
- Data constraintsIdentify personal or sensitive data, your customers and any enterprise security reviews.
- Existing assetsGather designs, prototypes, repositories, your domain, hosting and third-party accounts, with admin access.
- Next stepsBring your thoughts on what the first version needs and what could follow it.
Cost & time
What affects the cost and timeline
The work grows with the rules, connections and data your product needs to handle.
Billing rules
Usage charges, per-seat pricing, currencies, tax and invoicing each add rules to build and test.
Real-time features
Collaborative editing, live dashboards and chat need extra infrastructure and testing.
Enterprise requirements
Single sign-on, audit logs, data export and security questionnaires add work to the scope.
Integrations and public APIs
Connections to other products need building; a customer-facing API also needs documentation and support.
Large data sets
Imports, exports and reports can need background jobs and careful performance work.
Avoid
Mistakes to avoid
Building every common component from scratch
Use proven services for sign-in, billing and permissions to keep more of the budget for the product itself.
Leaving customer data separation until later
Design it into the first version of a multi-customer product to avoid a risky rewrite.
Assuming payment events arrive once and in order
Make webhook handlers skip events already processed and avoid depending on their order.
Releasing without a staging environment or tested backups
Test changes away from the live product and check that backups work before they are needed.
Questions
Asked by businesses in London
Page updated 5 November 2026
How much does a web application cost?
There is no fixed price. Subscription billing rules and the hosting setup are two drivers: plans, trials, invoices and failed payments add decisions, while deployment, staging, backups and transactional email need configuration. Agreeing the first-version scope gives you a clearer basis for a quote.
Should each customer have a separate database?
It depends on your customers’ requirements. A shared database is simpler to run, while a separate database for each customer suits enterprise buyers with strict isolation or data-location requirements. Discuss those requirements before choosing the data setup, especially if enterprise customers are part of your plan.
Can you build a first version of my SaaS idea?
Yes. We help you decide what the first version must include, build it and plan what comes next. That gives you a defined starting point for your product, with a view of later work instead of having to put every idea into the initial build.
Can you take over an existing application?
Yes. We start by reviewing the code and infrastructure, then fix what matters most. If your first version has slow pages or code the team is reluctant to touch, that review gives us a basis for fixes and a plan before adding new features.
Who owns the application and its accounts?
You do. You own the code, repositories, hosting accounts and data. That means the application and the accounts holding its code and data belong to you after the build, so you can make decisions about how the product is maintained and developed.
What happens after launch?
We set up the domain, email and analytics at launch, followed by ongoing support. Frameworks, libraries and hosting need regular security updates even when you are not adding features. You can also track activation, retention and churn alongside revenue to see how users return to the product.
