What We Build
Project Management Tools
Tailored project and task management systems that match your workflow - not the other way around.
Finance & Invoicing Tools
Custom finance dashboards, invoicing systems and reporting tools built for your specific requirements.
Event Management Platforms
End-to-end event management tools - registrations, schedules, attendee management and more.
Anything Else
If it can be built on the web, we can scope and build it. Every project is discussed, scoped and quoted individually.
CRM & Client Management
Off-the-shelf CRMs force your sales process into someone else's data model. A bespoke CRM is built around the stages, fields, automations and reporting your team actually uses - no unused modules, no per-seat pricing, and no monthly subscription fees that scale against you as you grow.
Project Management Tools
We build project management tools for businesses whose work doesn't fit a Kanban board or a Gantt chart out of the box - agencies with bespoke production workflows, professional services firms with regulated processes, and operators running multi-stakeholder delivery models.
Finance & Invoicing Tools
From bespoke invoicing systems with automated reminders and payment integrations, to internal finance dashboards that pull data from accounting software, banking APIs and operational systems into a single view - we build the financial tooling your business actually needs.
Event Management Platforms
Event management platforms covering registration flows, ticketing, attendee communications, schedule management, sponsor portals and post-event reporting - built once, owned outright, and reused across every event you run.
Anything Else
Internal calculators, customer-facing portals, marketplace prototypes, data ingestion pipelines, AI-assisted internal tools - if it runs on the web, we can scope it. Every project is discussed and quoted individually based on requirements.
Our Build Process
A predictable five-stage process designed to remove the unknowns from a bespoke build. Every stage produces an artefact you sign off before the next stage begins.
- 01
Discovery
A structured discovery call to understand the workflow you're trying to support, the constraints you're operating under, and the outcomes you need the tool to produce. Typical duration: 1 to 2 sessions.
- 02
Scope & quote
We document the build as a clear feature list with acceptance criteria, then return a fixed-scope quote and timeline. No discovery fees, no surprises mid-build. Typical turnaround: 3 to 5 working days.
- 03
Design
Wireframes and UI mockups for every screen, reviewed and signed off before a line of production code is written. Designing the tool on paper is an order of magnitude cheaper than redesigning it in production.
- 04
Build
Production build with regular demos throughout - typically every one to two weeks. You see progress as it happens, give feedback while change is still cheap, and never receive a black-box delivery at the end.
- 05
Handover & ongoing support
Full handover including documentation, training, and source code. Ongoing support and feature development is available on a retainer basis for clients who want a long-term technical partner - but you own the codebase and can take it elsewhere at any time.
Tech Stack & Engineering Approach
BCS builds primarily in React and TypeScript on the frontend, with PostgreSQL and Node.js or Python on the backend depending on the project. We deploy to managed infrastructure - typically Vercel and Supabase - to keep operational overhead low and allow rapid iteration.
Every build ships with automated tests on critical business logic, role-based access control where multi-user, audit logging on financial and regulated workflows, and CI/CD so changes go live in minutes, not days. We do not ship code we wouldn't be willing to maintain ourselves for the next five years.
Who We Build For
BCS builds custom web tools for businesses across all sectors - from professional services firms needing bespoke client management systems, to growing SMEs outgrowing off-the-shelf software, to founders who need a specific internal tool built properly and maintained long term.
Why Not Just Use Off-The-Shelf Software?
Off-the-shelf tools are built for the average use case. If your workflow is even slightly non-standard - and most businesses' are - you end up bending your process to fit the software rather than the other way around.
A bespoke web tool is built entirely around how your business operates. No unnecessary features. No workarounds. No per-seat pricing that scales against you as you grow. Just a tool that does exactly what you need it to do.
How a Custom Web Tool Pays for Itself
The cost case for a bespoke build usually breaks down across three categories. Subscription replacement: a bespoke tool removes per-seat SaaS fees that compound every time you hire - a 25-seat CRM at £80 per seat per month is £24,000 a year, indefinitely. Process efficiency: a tool built around your actual workflow removes the workarounds, spreadsheets, and manual data shuffling that swallow operational hours. Strategic differentiation: internal capability your competitors don't have - and can't buy - is a durable competitive advantage.
Built to Grow With You
Every tool we build is designed to be extended. As your business evolves, your tools can evolve with it - new features, new integrations, new users. You own it outright. There are no subscriptions, no vendor lock-in, no price hikes.
Pricing
All custom web tool projects are scoped and quoted individually based on requirements. There is no fixed pricing - every build is different. Typical project budgets start around £8,000 and scale according to scope.
