What we build

Six things we build into every web app

From an internal workflow tool replacing a 12-tab spreadsheet, to a multi-tenant B2B SaaS product, to a PWA your field team installs to their phone — all built around your specific workflow and the tools your business already runs on.

  • Custom Business Web Apps

    Internal tools, workflow apps, ops dashboards, custom CRMs, quoting and approval systems — replacing the Excel-and-email patchwork your team has outgrown.

    • Internal tools & workflow apps
    • Ops dashboards · custom CRMs
    • Quote-to-cash & approvals
  • SaaS Products & MVPs

    B2B SaaS products, multi-tenant platforms, lean MVPs that go from idea to paying customers in 12–20 weeks. Built for product-market-fit, not for an agency-sized invoice.

    • B2B SaaS · multi-tenant
    • Lean MVP development
    • Stripe billing · auth · onboarding
  • Web Portals

    Customer, partner, supplier, employee, student, member, learning and training portals — secure, branded, integrated into your back-office systems and ready for self-service.

    • Customer · partner · supplier
    • Employee · staff · member
    • Learning · training · student
  • Progressive Web Apps

    PWAs that install to the home screen, work offline on patchy networks and run on every device without the app-store dance. Push notifications · background sync · device APIs.

    • Installable · offline-capable
    • Push notifications
    • Works on iOS · Android · Desktop
  • Modern Tech Stack

    React · Angular · Vue · Node.js · TypeScript. Real engineering — not a no-code platform you outgrow. Hosted on Azure or AWS, with CI/CD and observability built in from day one.

    • React · Vue · Angular front-end
    • Node.js · TypeScript back-end
    • Azure / AWS · CI/CD · monitoring
  • Integrations

    Your custom web app connected to the tools your business already runs on — Xero, HubSpot, Salesforce, Stripe, Power BI, Deputy, Shopify — plus custom APIs and legacy database bridges.

How it runs

A custom web app project, end to end

Three stages. Two-week sprints. Weekly demos — never a launch-day reveal. Delivered personally by the founder.

  1. Week 0

    Product Discovery

    15-minute scoping call. We map the workflow, the users, the systems you need to integrate and the must-ship features for V1. Fixed-price quote inside 48 hours — no estimates, no T&M surprises.

  2. Weeks 1–N

    Build in Sprints

    Two-week sprints with weekly demos. You see working software every Friday — not a Gantt chart. Scope and priorities adjust each sprint while the price stays fixed. Code lives in your GitHub from day one.

  3. Launch

    Ship & Support

    Production launch on Azure or AWS. Hand-over docs, runbooks and training for your team. 30 days of post-launch support included by default; ongoing maintenance is month-to-month — never locked-in.

Common questions

Before you book the scoping call

How much does a custom web app cost?

Fixed-price after a 15-minute scoping call and a short discovery session. A focused internal tool or MVP typically takes 6–10 weeks. A full SaaS product or multi-portal platform takes 12–24 weeks. You know the price before any code is written — no day-rate creep, no "Phase 2" billing surprise. You own the code.

How long does a custom web app take to build?

Simple internal tools (one user role, one main workflow): 4–8 weeks. Standard business web apps (multi-role, several integrations, reporting): 8–16 weeks. SaaS MVPs ready for paying customers: 12–20 weeks. Enterprise platforms with deep integrations: 5–9 months. Sprint demos every two weeks — you see working software the whole time, not a launch-day reveal.

Do you build SaaS products and MVPs?

Yes — and we build them lean. The mistake we see most is founders spending a fortune on a full V1 before they have a paying customer. We build the smallest version that proves the value proposition (auth, the core workflow, Stripe billing) in 12–16 weeks, then iterate based on what real users actually do. Multi-tenant architecture, white-labelling and team accounts are standard.

Which framework do you use — React, Vue or Angular?

Default is React + TypeScript on the front end, Node.js + TypeScript on the back end, PostgreSQL or SQL Server for data, hosted on Azure or AWS. We also build with Vue and Angular when there's an existing codebase or strong team preference — but we won't pick a stack purely for novelty. Boring, well-supported, easy-to-hire-for is the right answer.

What about Progressive Web Apps — do they really work offline?

Yes. PWAs install to the home screen on iOS and Android, run full-screen, send push notifications and cache the app shell + recent data so users can keep working when the network drops. Service workers handle background sync — when the device comes back online, queued changes upload automatically. For field-services, healthcare and education use cases this matters a lot.

Do you handle hosting and ongoing maintenance?

Yes — but you're never locked in. We deploy to your Azure or AWS account (the cloud bill is yours). Ongoing maintenance is month-to-month — security patches, dependency updates, small enhancements. Cancel anytime and your code keeps running.

Can you integrate with our existing tools — Xero, HubSpot, Salesforce, Stripe, our internal API?

Yes. Most custom web apps we build talk to 3–8 external systems on day one. Accounting (Xero / MYOB / QuickBooks), CRM (HubSpot / Salesforce / Pipedrive), payments (Stripe / Square), rostering (Deputy / Employment Hero), reporting (Power BI), e-commerce (Shopify / WooCommerce) — plus your internal SQL Server, REST or SOAP APIs, EDI feeds or legacy database bridges.

Do we own the code?

Yes. Every engagement results in source code that you own outright, hosted in your GitHub or Azure DevOps from day one. No per-seat or per-user SaaS subscription to us. You can take the codebase to another developer at any time — and the way we structure projects (clean architecture, documentation, no proprietary frameworks) means another team can pick it up without re-platforming.
