Stop losing time to systems that don't talk to each other
We fix that.
We build custom software , API integrations , and system integrations for businesses that are tired of clunky workarounds and manual processes. Our job is to connect your tools, automate the repetitive work, and give your team back the time to focus on what actually grows the business.
We believe your team's time is too valuable to spend on work software should handle
When your systems don't connect, your people pay the price. Every manual export, every duplicate data entry, every spreadsheet workaround is a tax on the business you're trying to grow.
We close that gap. Custom software development, API integrations, and AI-powered automation , built specifically for your business, so the manual work disappears and your team gets back to what matters.
50+ teams worldwide decided their time was worth more than manual workarounds.
Merto Software (often confused with ‘Metro Software’) is a UK-based software development company that provides cutting-edge software and IT solutions to businesses across the UK and worldwide.

Built to Scale

Everything you need to stop working around broken tools
We don't offer generic solutions. Every service is built around one goal: removing the operational friction that's stopping your business from scaling.

- AI chatbots and virtual assistants for customer service
- Automated document processing and data extraction
- Business workflow automation tools

Technology Consulting

- Software architecture roadmaps and future-proofing
- Security, compliance and data handling guidance
- ROI-focused discovery workshops before any work begins

- Bespoke web applications for your processes
- Legacy system modernisation and data migration
- Scalable, secure and easy-to-maintain builds
- Built to grow with you, not replaced when you do
Mobile App Development
Your customers and field teams are mobile. Your software should be too. We build iOS and Android apps from a single codebase, designed to work beautifully even without a signal.
- iOS and Android apps from one codebase
- Offline-first design for field and remote teams
- User-friendly interfaces customers actually love
- Enterprise-ready mobile app distribution and support

From fast-growing startups to established brands, we partner with teams that are done settling for software that holds them back.
A clearer way to build, ship, and scale

From the first conversation to long-term support, one consistent process. No handoffs, no surprises.
Discover Your Challenges
We identify what's slowing down your business and costing you money. This isn't a sales call. It's a genuine diagnostic. We ask the hard questions, challenge assumptions, and leave you with clarity on exactly what's holding you back, whether you work with us or not.
