FAQs

Software development is the process of designing, building, testing, and deploying digital applications or systems that solve specific business problems or support operations.

It involves everything from planning and design to coding, testing, and ongoing maintenance.

Businesses typically need software development when:

  • Existing tools do not fully support their workflows
  • Multiple systems need to be integrated
  • They are building a new product or SaaS platform
  • They want a competitive advantage through technology
  • They are scaling and need more robust systems
  • There are specific security, compliance, or data ownership requirements

While it may require a higher initial investment, it delivers long-term value through flexibility, efficiency, and the ability to adapt as the business grows.

Costs vary based on complexity, technology stack, and timeline.

  • Simple applications: £2,000 – £10,000
  • Mid-level platforms: £10,000 – £100,000
  • Enterprise systems: £100,000+

Developer rates typically range from £30 to £150 per hour.

Accurate pricing requires a proper discovery phase to avoid budget overruns.

Timelines depend on project complexity:

  • Simple tools: 4–8 weeks
  • Mid-level platforms: 3–6 months
  • Large systems: 6–18 months


Typical breakdown:

  • Discovery: 1–3 weeks
  • Design: 2–6 weeks
  • Development: 60–70% of timeline
  • Testing: 2–4 weeks
  • Deployment: 1–2 weeks


Agile methodology
ensures early delivery of working features.

Waterfall is a linear process with fixed stages and limited flexibility. It works best when requirements are stable.

Agile is an iterative approach, using short sprints to deliver working features continuously. It allows flexibility, regular feedback, and evolving requirements.

Most modern teams prefer Agile due to faster delivery and reduced risk.

Technology stacks vary based on project requirements.

  • Frontend: React, Angular, Vue
  • Mobile: Swift, Kotlin, Flutter
  • Backend: Node.js, Python, Java, .NET
  • Databases: PostgreSQL, MongoDB
  • Cloud platforms: AWS, Azure, Google Cloud
  • AI tools: TensorFlow, PyTorch
  • DevOps: Docker, Kubernetes, CI/CD tools

Technology should be chosen based on scalability, use case, and long-term goals

SaaS (Software as a Service) is cloud-based software delivered via a subscription model. Examples include Slack, Shopify, and Zoom.

Development includes:

  • Multi-tenancy architecture
  • Subscription billing integration
  • Scalable cloud infrastructure
  • Authentication and access control
  • API integrations
  • User onboarding systems

Typical development time: 6–12 months.

In most cases, the client owns the code after full payment.

However, agencies may retain ownership of pre-built frameworks, libraries, or tools used in the project.

Contracts should clearly define:

  • Ownership rights
  • Third-party components
  • Code reuse rights
  • Access to full source code

Always ensure code is stored in a client-owned repository.

Off-the-shelf software is ready-made and widely used.

Custom software
is built for specific business needs.

Key differences:

  • Cost: lower upfront vs higher upfront
  • Fit: generic vs tailored
  • Ownership: vendor vs client
  • Scalability: limited vs flexible
  • Competitive advantage: common vs unique

Most businesses use a combination of both.

Software maintenance ensures ongoing performance, security, and reliability.

It includes:

  • Security updates
  • Compatibility updates
  • API changes
  • Performance optimization
  • Bug fixes
  • Feature enhancements

Businesses should budget 10-20% annually of the development cost for maintenance.

Key factors to evaluate:

  • Portfolio and relevant experience
  • Technical expertise
  • Development methodology
  • Communication and project management
  • IP ownership clarity
  • Post-launch support
  • Client reviews and references
  • Transparent pricing

A reliable agency provides detailed estimates after a proper discovery phase.
