Service

Mobile App Development

Mobile applications connected to the systems you already run, rather than another disconnected island.

What this service is

Business mobile app development means building an application for phones and tablets that reads and writes your real operational data. The hard parts are rarely the screens: they are authentication, offline behaviour, synchronisation conflicts and keeping the app working as the backend changes.

The problem

What usually brings people here

Field staff are blind

People working away from a desk cannot see or update the system, so work is recorded on paper and entered later.

Approvals block on a desk

Orders and requests wait because the approver has to be at a computer.

An app disconnected from the data

An app exists but holds its own copy of everything and never reconciles with the system of record.

No signal where the work happens

Warehouses, sites and vehicles have patchy connectivity, and an online-only app is unusable there.

Capabilities

What we do

  • Mobile application design and development
  • Integration with existing ERP and business systems
  • Offline-first data handling and sync
  • Authentication and device-level security
  • Push notifications and alerts
  • Barcode, camera and location capture
  • Release management to app stores
  • Ongoing maintenance against OS updates

Use cases

Typical engagements

Field operations

Job details, checklists, photo capture and completion recorded on site and synchronised when a connection returns.

Warehouse and stock

Barcode-driven picking, receiving and stock counts writing directly to the system of record.

Approvals and visibility

Managers approving orders and leave, and seeing live operational numbers, away from a desk.

Delivery

How the work runs

  1. 01

    Discovery & requirements

    We map how the work actually flows today — the systems, the spreadsheets, the manual handoffs — and agree what success looks like in measurable terms.

  2. 02

    Solution architecture

    Data model, service boundaries, integration points and hosting. You get the shape of the system before anyone writes production code.

  3. 03

    UX & technical design

    Screens and flows for the people who will use it daily, reviewed against the architecture so the design is buildable as drawn.

  4. 04

    Development & integration

    Built in increments you can see and use. Integrations are wired early, because that is where most projects actually go wrong.

  5. 05

    Testing & quality assurance

    Automated tests around the logic that matters, plus migration rehearsals against real data shapes before anything goes near production.

  6. 06

    Deployment & onboarding

    Release pipeline, environment configuration, data migration and training for the teams who have to live with the system.

  7. 07

    Support & continuous improvement

    Monitoring, fixes and the next increment. Software that is used changes; the engagement allows for that.

Before you commit

What to weigh up

Decide early whether the app must work offline — it changes the architecture fundamentally, because you then need conflict resolution, not just caching. Factor in the ongoing cost of OS updates and store policy changes: a mobile app is a maintenance commitment, not a one-off build.

Questions

Frequently asked

Native or cross-platform?
Cross-platform suits most business applications and halves the maintenance surface. Native is worth it when you depend heavily on device hardware or need platform-specific behaviour.
Can the app work offline?
Yes, with design for it from the start: local storage, a sync queue and explicit conflict resolution rules for when two people changed the same record.
Will it connect to our ERP?
That is normally the requirement. The app works against an API layer over your existing system rather than holding a separate copy of the data.
Do you handle app store releases?
Yes, including store listings, review submissions and the release process for updates.
