Define what needs to improve before deciding what to build. We focus on your business challenges and operational needs first.
Core Service
Custom dashboards, internal systems, portals, and workflow automation for UK businesses, built around your actual workflow with a verifiable delivery record: 65+ projects delivered and a 4.7★ average client rating.
Custom software development is the design and build of software made for one business's specific workflows, rather than a generic product sold to everyone. KeyTech builds internal systems, client and supplier portals, dashboards, and workflow automation for UK businesses. Does your process genuinely need custom software, or would a well-configured existing tool do the job for less? We will tell you honestly either way. Custom development only makes sense once you have outgrown what off-the-shelf tools can realistically support.

OUR APPROACH
The right software should fit the way your business operates, not force your team into a rigid workflow. At KeyTech, we start by understanding your requirements, existing systems, and operational challenges before recommending an approach.
Define what needs to improve before deciding what to build. We focus on your business challenges and operational needs first.
Establish the functionality, priorities, timeline, and budget before development begins, so expectations are clear from the start.
Break larger projects into manageable milestones so you can review progress, provide feedback, and validate decisions throughout delivery.
Consider integrations, maintainability, security, documentation, and future changes from the beginning.
Agree on source-code ownership, deployment access, documentation, and handover arrangements in the project contract.
KeyTech is based in Gandhinagar, India, and works with businesses seeking practical software solutions for their operational needs.
PRICING
Custom software development in the UK typically costs £15,000–£500,000+ (GBP, excluding VAT), depending on complexity. Smaller internal tools and focused applications may cost £15,000–£50,000, while mid-complexity business systems often fall between £50,000 and £150,000. Enterprise platforms with extensive integrations, security requirements, and complex workflows can cost considerably more. The final cost depends on project scope, integrations, data migration, user roles, and compliance requirements. These figures are indicative planning estimates based on published UK development agency guides, not fixed quotes.
Replaces Excel workbooks. 1–2 user roles, central database, reporting and exports. Typical timeline 6–10 weeks.
Client or supplier portal, Xero/Sage/Stripe sync, granular permissions, audit logs, automated alerts. Typical timeline 3–5 months.
Legacy migration, high-volume processing, SSO, and strict compliance. Typical timeline 6–10+ months.
COST DRIVERS
Two projects that look similar can differ by tens of thousands of pounds. These five factors explain most of the gap.
Proven component frameworks like Filament or Tailwind UI can cut frontend time by roughly 30–40% for internal tools. Fully bespoke, brand-led interfaces add £8,000–£20,000.
Standard APIs (Xero, Stripe, GoCardless, SendGrid) take around 15–30 hours each. Legacy or proprietary systems take 40–90+ hours.
Clean databases migrate predictably. Years of inconsistent spreadsheets can add £3,000–£9,000.
Multi-tenant hierarchies (suppliers, field staff, finance, directors) cost more than a single staff view.
Meeting UK GDPR and the Data Protection Act 2018 shapes hosting, retention, access controls, and audit trails.
AFTER LAUNCH
Budget 15–20% of the initial build cost per year for maintenance, security updates, and minor improvements. Ask any vendor what is not in the quote.
Frameworks, browsers, and third-party APIs change. Dependency updates and monitoring keep the system secure and reliable.
Commonly £40–£300 per month on UK or EU infrastructure, scaling with load.
Transactional email, SMS, mapping, and payment fees are separate from development and should be budgeted.
BUILD VS BUY
Custom software pays off when the cost of manual work and tool sprawl clearly exceeds the build cost.
Annual cost of the problem = (hours lost per week × hourly staff cost × 52) + wasted SaaS subscriptions.
15 staff each lose 4 hours a week to reconciliation and re-entry. At a blended £30/hour that is about £93,600 a year. Add £14,400 in overlapping SaaS fees and the drain is roughly £108,000 a year. A £55,000 portal that removes most of that can pay for itself within roughly a year. Real savings depend on how much manual work is actually eliminated.
If your team loses under 10 hours a week and a £60/month tool solves 90% of the problem, do not build custom software. We will say so.
HOSTING & COMPLIANCE
UK businesses have specific data-protection, tax, and accounting requirements. We design for them from the start.
Access controls, retention rules, audit trails, and data-subject request workflows designed around ICO expectations.
Deployment on UK (London) or EU cloud regions, with encrypted backups and role-based access.
Integrations with Xero, Sage, QuickBooks, Stripe, and GoCardless, built around VAT and Making Tax Digital workflows where relevant.
