Enterprise Software Development

Mission-critical software that scales, performs, and stays secure

Enterprise organisations need more than a development team. They need a partner who understands compliance, integration complexity, and what it takes to keep business-critical systems running at scale. AI-augmented delivery means we build faster without cutting corners.

Enterprise challenges

What makes enterprise different

Enterprise software development is not just bigger custom software. It operates under a different set of constraints that demand specialist experience.

Scale and availability

Enterprise systems serve thousands of concurrent users across multiple teams and geographies. Downtime is not an inconvenience; it is a business-critical event that costs revenue and erodes trust.

Compliance and governance

ISO 27001, Cyber Essentials Plus, GDPR, and sector-specific frameworks are not optional. Enterprise software must be designed for auditability, data residency, and regulatory change from the first line of code.

Integration complexity

Enterprise environments rarely start from a blank slate. New systems must integrate with ERPs, CRMs, legacy databases, and third-party APIs without disrupting the operations they depend on.

Multi-team coordination

Large programmes span multiple workstreams, vendors, and stakeholders. Effective governance, clear interfaces between teams, and rigorous change management are essential.

What we deliver

Enterprise capabilities on Azure

Our architecture decisions are grounded in real production experience with government, education, transport, and fitness organisations operating at national scale.

Cloud-Native Architecture on Azure

We design for scale using Azure Kubernetes Service (AKS), Azure SQL, Cosmos DB, and event-driven architectures with Service Bus and Event Grid. High availability, disaster recovery, and auto-scaling are built into the architecture, not added later.

Microservices and Domain-Driven Design

Complex domains are decomposed into bounded contexts with clear ownership. Each service is independently deployable, testable, and scalable, allowing teams to move fast without stepping on each other.

Enterprise Integration

REST, gRPC, GraphQL, and async messaging patterns connect your new system with existing enterprise applications. Azure API Management provides governance, rate limiting, and developer portals for internal and external consumers.

AI-Enhanced Enterprise Applications

AI is not a separate project; it is embedded where it delivers value. Document intelligence, predictive analytics, recommendation engines, and natural language interfaces built on Azure OpenAI and Semantic Kernel.

Security and Compliance by Design

Threat modelling, role-based access control, encryption at rest and in transit, and automated vulnerability scanning are part of every sprint. We are ISO 27001 certified and Cyber Essentials Plus accredited.

Infrastructure as Code and DevOps

Bicep templates define every environment. GitHub Actions or Azure DevOps pipelines automate build, test, and deployment. Every change is traceable, repeatable, and auditable.

How we deliver

Enterprise delivery, accelerated by AI

Our delivery methodology balances the rigour enterprise programmes demand with the speed AI-augmented development enables.

Step One 1-2 weeks

Strategic Assessment

We assess the business case, technical landscape, compliance requirements, and integration points. Cursor and Claude Code accelerate analysis of existing systems and data. You receive a clear architecture vision, delivery roadmap, and risk assessment before a single line of code is written.

Step Two 2-4 weeks

Foundation Sprint

We establish the project foundation: architecture, infrastructure-as-code, CI/CD pipelines, monitoring, and security controls. The team builds a walking skeleton that proves the architecture end-to-end before feature development begins.

Step Three

Iterative Delivery

Agile delivery in two-week sprints with AI-augmented development accelerating every phase. Regular demos, retrospectives, and stakeholder check-ins keep the programme aligned with business goals. We ship working software continuously, not in a big-bang release.

Step Four

Launch, Transition, and Support

Production deployment with comprehensive monitoring, documentation, and knowledge transfer. Our managed application support team provides ongoing SLA-backed maintenance, ensuring your investment delivers value long after launch.

FAQ

Frequently asked questions

What makes enterprise software development different from standard custom software?

Enterprise projects operate at greater scale, with stricter compliance requirements, more complex integration landscapes, and higher availability expectations. They typically involve larger teams, longer timescales, and more rigorous governance. The architecture must account for multi-tenancy, audit trails, disaster recovery, and regulatory change from the outset.

How do you handle enterprise security and compliance?

Security is embedded in every sprint, not added at the end. We conduct threat modelling during architecture, implement role-based access control, encrypt data at rest and in transit, and run automated vulnerability scanning in CI/CD pipelines. Talk Think Do is ISO 27001 certified and Cyber Essentials Plus accredited. We regularly work within GDPR, GDS, and public sector security frameworks.

Can you integrate with our existing enterprise systems?

Yes. Enterprise integration is a core capability. We work with REST, gRPC, GraphQL, and async messaging patterns (Azure Service Bus, Event Grid, Event Hubs). Azure API Management provides governance for complex API landscapes. We have integrated with ERPs, CRMs, legacy databases, and bespoke internal systems across every sector we work in.

How much does enterprise software development cost in the UK?

Enterprise programmes typically range from £150,000 to £1M+ depending on scope, compliance requirements, and team size. We provide detailed estimates after a strategic assessment. Our AI-augmented development approach means you get more delivered, faster, within the same budget. See our pricing guide for indicative ranges.

Do you work with public sector organisations?

Yes. Talk Think Do is a Crown Commercial Service supplier on the G-Cloud and Digital Outcomes and Specialists (DOS) frameworks. We have delivered for the Department for Education, Livestock Information Services, CalMac Ferries, and other public sector bodies. Our ISO 27001 and Cyber Essentials Plus certifications meet public sector procurement requirements.
