01 / CAPABILITIES

Sixteen ways we build custom web applications.

From SaaS products and internal tools to client portals, workflows and full-stack systems. We design and ship applications that solve real operational and product problems.

01

SaaS product development

Multi-tenant web products from MVP to scale: auth, billing, roles, dashboards and the features your users need.

02

Internal tools & dashboards

Operations, reporting and workflow tools that replace spreadsheets and give teams a single place to work.

03

Client & partner portals

Secure portals for customers, partners or vendors to access data, submit requests and collaborate with your team.

04

Workflow automation

Custom applications that encode your processes, approvals and notifications so work moves without constant manual chasing.

05

API & system integration

Connect CRMs, ERPs, payment providers, Shopify and third-party APIs so data flows and tools work as one system.

06

Full-stack web applications

React/Next.js frontends with robust backends, databases and hosting — designed for performance, security and growth.

07

Responsive & mobile-ready UX

Interfaces that work cleanly on desktop and mobile so field teams and clients can use the app anywhere.

08

Authentication & permissions

Role-based access, SSO options and audit-friendly security designed around who needs to see and do what.

09

MVP to production path

Scoped first versions that prove value quickly, then a clear roadmap to harden, expand and scale the product.

10

Product design & UX

User flows, interface design and usability testing so the application is intuitive for the people who use it daily.

11

Admin & operations panels

Back-office interfaces for content, users, orders, configuration and support without exposing complexity to end users.

12

Scalable architecture

Clean structure, APIs and infrastructure choices that support more users, features and teams over time.

13

Legacy modernisation

Rebuild or extend ageing systems with modern stacks while protecting critical data and business continuity.

14

B2B & multi-tenant apps

Organisation-aware applications with company accounts, roles and data isolation for B2B and platform products.

15

Hosting & DevOps

Deployment, monitoring, backups and environments set up so the application stays reliable after launch.

16

Analytics & product insights

Event tracking, usage metrics and reporting so you can see how the application is used and where to improve.

02 / PROCESS

How a custom web application engagement runs.

Every engagement follows the same four stages. You always know what is happening next and how success is measured at each milestone.

  1. Stage 1

    Discovery & scoping

    We clarify users, problems, success metrics and constraints, then define a phased scope, architecture options and a realistic delivery plan.

  2. Stage 2

    Design & architecture

    User flows, interface design and technical foundations are locked in: data model, auth, integrations and the first vertical slice of the product.

  3. Stage 3

    Build & iterate

    We develop in sprints with regular demos. Core workflows ship first so you can validate early; features expand from a stable foundation.

  4. Stage 4

    Launch, hand over & support

    Deployment, monitoring, documentation and training. Optional retainer support keeps the application improving after go-live.

05 / WHY BRANDS STAY

Six reasons organisations stay with us for custom applications.

Most of our application work is repeat business or referral. These are the reasons clients give when we ask why.

Product thinking + engineering

We don’t just code requirements. We help prioritise, simplify and design applications people will actually use.

Phased delivery means you get a working core first, then expand — not a long wait for a big-bang launch.

A dedicated lead on every project

One accountable owner, clear weekly updates, no account-manager telephone game.

Maintainable by your team

Modern stacks, clear structure and documentation so you are never locked into us for every change.

07 / FAQ

Questions we hear before every application engagement.

Honest answers, including the ones most agencies dodge.

Get a free application scoping session
How long does a custom web application take?

MVPs and focused internal tools often ship in 8–16 weeks. Larger multi-module products are phased. Every quote includes a fixed timeline for the agreed scope.

Do you build MVPs or only full products?

Both. We specialise in scoped first versions that prove value quickly, then expand. You are never forced into a multi-year build before learning from real users.

What technologies do you use?

Primarily React/Next.js on the frontend with Node.js and PostgreSQL on the backend, hosted on modern platforms. We recommend the stack based on your requirements and team, not trends.

What does a typical engagement cost?

Project builds: $15K–$120K+. Monthly retainers: $4K–$15K/mo. Dedicated team: $12K–$40K/mo. Every quote is fixed-fee and locked in the SOW.

Will our team be able to maintain the application?

Yes. We use clear architecture, TypeScript and documentation. The goal is a product your team can own and extend, not a black box.

Can you integrate with our existing systems?

Yes. CRM, ERP, payment providers, Shopify, email tools and custom APIs are routinely integrated so the application fits into your existing stack.
