Software Development FAQs
How much does custom software development cost in the UK?
Custom software costs vary based on complexity and scope. Small to mid-range projects typically range from £20,000-£75,000, while enterprise solutions can be £75,000-£500,000+. We provide detailed estimates after a free discovery workshop. Our transparent pricing model ensures no hidden costs.
What's the difference between off-the-shelf and custom software?
Off-the-shelf software offers generic solutions that may not fit your exact needs. Custom software development creates a tailored solution built around your specific business processes, giving you complete control, competitive advantage, better integration with existing systems, and long-term cost efficiency.
How long does custom software development take?
A typical MVP takes 8-16 weeks. Mid-complexity applications take 3-6 months. Enterprise-grade software can take 6-12+ months. We use agile methodology, so you receive working increments every 2 weeks and can launch in phases.
Do you develop SaaS platforms?
Yes, we are an experienced SaaS development company. We build scalable, multi-tenant SaaS platforms with subscription management, user onboarding, analytics dashboards, API integrations, and cloud-native infrastructure on AWS or Azure.
Can you modernise our legacy systems?
Absolutely. We specialise in legacy system modernisation - migrating from monolithic architectures to microservices, upgrading outdated tech stacks, and re-platforming to the cloud, all while ensuring zero disruption to your ongoing operations.
How do you ensure software quality and security?
We follow industry best practices including automated testing (unit, integration, e2e), code reviews, OWASP security guidelines, penetration testing, and continuous monitoring. Our software meets enterprise-grade security and compliance standards including GDPR, SOC 2, and ISO 27001.
