Why we do this
Capable businesses deserve software that works as hard as they do
We started Merto because we kept seeing the same pattern: talented teams, ambitious plans, and technology that wasn't keeping up. Not because the right solutions didn't exist, but because nobody had taken the time to connect everything properly.
That's the gap we fill. We take the time to understand how your business actually runs, not just how your software is supposed to run, then build the integrations that close the distance between the two.
Your time matters
We measure success by how many hours your team gets back, not by how complex the solution is.
No surprises
Fixed pricing, clear timelines, and documentation your team can actually understand.
Built to last
Every integration we build is designed to grow with your business, not become tomorrow's bottleneck.
The real cost
Disconnected systems aren't just an IT problem.
They're a
people problem.
Most businesses don't realise how much it's adding up until they see the numbers. Every hour spent re-entering data is an hour not spent selling, building, or serving customers.
Wasted every week
Your team manually re-entering data between systems that were never designed to talk to each other.
Sync errors per month
Each one needing someone to catch, investigate, and fix before it causes a larger problem downstream.
Lost monthly
To avoidable inefficiency, errors, and staff time spent on workarounds instead of the work that matters.
API Integration Services
API integration services built for the way your business actually works
From third-party software integration to legacy system modernisation, we connect your tools and automate the data flows your team currently handles by hand.
Custom API Development
Your business has specific workflows that off-the-shelf software was never built for. We build custom APIs that fit exactly how you work, scaling as your requirements grow.
Third-Party Software Integration
Your business shouldn't grind to a halt because two systems can't share data. We connect your tools so information flows automatically, and your team gets back to the work that actually requires their attention.
Real-Time Data Synchronisation
Running your business on data that's hours out of date means making decisions you can't fully trust. We build real-time data synchronisation so every system reflects what's happening right now.
Secure and Compliant Integrations
Data moving between systems is data at risk. Every integration we build is encrypted, GDPR-compliant, and built to the security standards your industry requires.
Legacy System Integration
Older systems often hold years of critical business data, but they weren't designed to connect to modern tools. We bridge the gap without forcing an expensive system replacement.
Business Efficiency Automation
Manual workflows aren't just slow. They're a hidden cost your competitors avoid when they've automated them. We map your processes, find what's holding your team back, and build the integrations that remove the friction for good.
The platforms we connect every day
We work with all major business platforms
From Salesforce to Shopify, Xero to SAP. If it's in your business, we can connect it.

How we work
Our API integration process: clear, simple, effective
Discover Your Challenges
We learn about your business, the systems you use, and exactly where your team is losing time. This shapes everything that follows.
Design Your Solution
We map out how your systems will connect, what data will sync, and how it all works together. We agree on everything before we write a single line of code.
Build and Test
We build your integration and test every data flow thoroughly. Nothing goes live until we're confident it's accurate and reliable.
Go Live and Stay Supported
We manage the launch, make sure everything runs correctly, and stay available. Your first 30 days of support are included at no extra cost.

Real outcomes
What disconnected systems were costing our clients, and what we did about it
Businesses that were losing time, making errors, and spending money on manual processes they couldn't escape from. Each project started with a real problem and ended with a working API integration that saved hours every week.
E-commerce Integration
CRM + E-commerce sync
A fast-growing e-commerce brand was manually copying customer data between Shopify and HubSpot every day. Their team spent hours on data entry that never quite matched. We built a bi-directional sync that automated the entire workflow in real time.
Shopify
HubSpot
Financial Automation
ERP + Accounting automation
A finance team was manually reconciling SAP and Xero at the end of every month. It was a process taking days, prone to human error, and costing thousands in staff time. We automated the entire invoice sync and eliminated the manual work entirely.
Legacy Modernisation
Legacy system modernisation
A manufacturer running critical operations on a 20-year-old system couldn't connect it to the modern tools their business needed. The cost of replacing it was prohibitive. We built a REST API bridge that connected their legacy system to new cloud platforms without replacing a thing.
