Custom applications bring together the exact features, integrations and user experience your teams need, rather than forcing processes to fit generic tools.
Why Custom Software?
When standard software doesn t quite solve the problem
In many organisations, the most critical processes sit in spreadsheets, email threads or heavily customised packages that are hard to change. Custom applications give you the freedom to design a solution that matches your data, rules, users and integrations – without compromise.
-
Capture the exact workflows and business rules that matter to your organisation.
-
Integrate reliably with existing systems, data sources and identity platforms.
-
Flexible distribution options, including Google Play and private enterprise app stores.
-
Design user journeys around your teams, partners and customers not generic roles.
-
Control your own roadmap instead of waiting for vendor feature releases.
-
Own the IP and avoid long-term lock-in to a single proprietary product.
Tailored where it counts
Custom where you’re unique, standard where you’re not
ERS focuses custom development on the parts of your organisation that differentiate you – the workflows, integrations and experiences that off-the-shelf software can’t easily support – while leveraging proven platforms and components everywhere else.
Use Cases
Real-world Android application examples
Custom development can support everything from front-line operations to customer-facing portals. These examples show where bespoke applications often deliver the greatest value.
Operational & Workflow Platforms
Applications that orchestrate complex, multi-step workflows – from order handling and case management to scheduling and dispatch – with clear visibility and audit trails.
Operations, service delivery, logistics
Customer Portals & Self-Service
Secure portals where customers can view records, submit requests, track progress and manage accounts, integrated with back-office systems and support teams.
Utilities, membership, public services
Industry-Specific Line-of-Business Systems
Tailored applications that reflect the language, regulations and processes of a particular sector, where generic packages fall short or are too rigid.
Niche industries & specialist services
Data & Reporting Solutions
Custom reporting layers, data capture tools and management dashboards that bring together data from multiple systems into a single, usable view for decision-makers.
Management, operations & finance
Legacy System Replacement & Modernisation
Modern web and mobile applications that gradually replace ageing desktop or on-premise systems while preserving the business logic and data that still matter.
Organisations modernising legacy estates
Partner & Vendor Portals
Applications that let suppliers, partners or agents interact with your organisation securely – sharing data, documents and workflows without exposing internal systems directly.
Supply chain, partner networks, distributors
Our Services
End-to-end custom application development
ERS supports the complete lifecycle of custom software – from refining the problem through to architecture, development, integration and long-term support.
Discovery & Solution Design
We work with business and IT stakeholders to clarify objectives, map processes, capture requirements and shape a solution that balances value, complexity and budget.
Architecture & Technical Strategy
Our architects design the application structure, data model, integration approach and hosting model “cloud or on-premise” with security, scalability and maintainability in mind.
UX/UI & User Journeys
We create user journeys, wireframes and interface designs that make core tasks straightforward for staff, customers and partners, across devices and contexts.
Full-Stack Application Development
ERS delivers the application front-end and back-end using modern technologies and frameworks, backed by robust coding standards, testing and version control.
System Integration & Data Migration
We connect your custom application to existing systems
ERPs – CRMs – Middleware – Databases and external APIs
then plan data migration to minimise disruption.
Support, Enhancements & Roadmapping
After go-live, we provide monitoring, support and incremental improvements, helping you evolve the application as requirements, regulations and opportunities change.

How We Work
Our custom application development process
ERS uses a structured, collaborative process to deliver Android apps that fit your organisation and work well in real-world conditions, from pilot to full rollout.
1 DISCOVERY
Understand goals & context
We explore the problem, users, existing systems and constraints, then agree objectives, scope and success criteria for the solution and its first release.
2 DESIGN
Shape the solution
User journeys, data structures, integration points and UX are defined, alongside architectural decisions around hosting, security and technology stack.
3 BUILD
Implement & integrate
Our engineers build the application and its integrations in iterative sprints, with regular demos and opportunities to refine features based on feedback.
4 TEST
Validate quality & performance
Functional, integration, security and performance testing ensure the application behaves as expected and can cope with real-world usage and data volumes.
5 LAUNCH
Deploy & transition
We plan and execute go-live with you, coordinating data migration, cut-over steps, user training and hypercare support so the transition is controlled and transparent.
6 EVOLVE
Enhance & extend
After launch, we use analytics, feedback and operational experience to prioritise enhancements, new features and performance improvements in a sustainable roadmap.
Considering a custom application for your organisation?
Whether you need to replace a legacy system, build a new portal or
automate a critical workflow, ERS can help you shape, deliver and support a
custom application that fits your organisation.
FAQs
Custom application questions we’re often asked
How long does it take to build a custom application?
Timelines depend on scope, complexity and integrations, but many projects are delivered in phases – starting with a core release in a few months, followed by incremental enhancements. During discovery we’ll define a realistic plan and milestones with you.
Which technologies do you use?
We typically work with modern Microsoft and open-source technologies for web, mobile, databases and integration, choosing the stack that best fits your environment, support model and long-term plans. Specific choices are discussed and agreed during design.
Can you integrate with our existing systems?
Yes. Integration is a core strength for ERS. We routinely connect custom applications to ERPs, CRMs, middleware, legacy databases and cloud platforms using APIs, messaging, ETL tools and other integration patterns as appropriate.
Who owns the intellectual property?
The custom application we build for you, including its source code, is your organisation’s IP as set out in our standard engagement terms. ERS acts as your development and delivery partner, not the product owner.
