System integration is the process of connecting your separate software tools so they share data automatically, without anyone copying information between them. For UK SMEs, we connect your CRM, accounting, ERP, e-commerce, and job management tools with custom APIs and automated workflows, so every system in your business talks to every other system in real time. You keep the software you already use and eliminate the manual data entry between it. From £8,000, fixed-price, you own the code.

No jargon. Here is what system integration actually does for your business.
System integration means making your separate software tools talk to each other automatically. Instead of your team manually copying a customer's details from your CRM into your accounting system, the two systems share that data instantly. Instead of checking three different dashboards to see your sales, inventory, and invoices, you see everything in one place.
For UK SMEs, system integration is usually the fastest and most affordable way to eliminate manual admin work. You do not need to replace your existing software - you just need to connect it. That is what our system integration services do for businesses across the UK.
These are the integrations we build most often for UK small and medium-sized businesses.
When a deal closes in your CRM, the customer is automatically created in your accounting system. Invoices sync without manual entry. Payment status flows back to sales. No more double-keying customer data between Salesforce or HubSpot and Xero, QuickBooks, or Sage.
Orders from your Shopify or WooCommerce store flow directly into your ERP for fulfilment. Stock levels update in real time across all channels. Pricing changes in the ERP reflect instantly on the website. Your e-commerce platform and back office are always in sync.
Completed jobs in your job management system automatically generate invoices in your accounting software. Time sheets sync with payroll. Job costs roll up into financial reports. Your operations team and finance team share the same data without manual reconciliation.
These are just the most common patterns. If your systems are disconnected, we can integrate them. Book a free call to discuss your specific setup.
Three ways to connect your systems. We help you choose the right one for your business.
Best for: Systems with good APIs that just need someone to connect them.
We write custom code that calls each system's API directly. Data flows point-to-point between your tools. This is the most lightweight approach - fast to build, easy to maintain, and you own every line of code. Most single integrations between two systems use this approach.
Cost: From £8,000
Best for: Systems that do not have APIs, or where you need data transformation between formats.
We build a lightweight middleware layer that sits between your systems. It handles data transformation, routing, and error handling. This is ideal when your systems speak different languages - for example, when your legacy ERP exports CSV files but your CRM expects JSON.
Cost: From £12,000
Best for: Businesses with 4+ systems that need a centralised integration platform with monitoring.
We deploy a custom integration platform that manages all connections from one place. It includes dashboards, alerting, retry logic, and audit trails. This is the enterprise-grade approach, scaled down for SMEs. You get full visibility into every data flow across your business.
Cost: From £20,000

A proven 4-step process that de-risks every integration project.
We map your current systems, data flows, and pain points. We identify which integrations will deliver the most value and document the technical requirements. No assumptions - we see exactly how your business operates.
We design the integration architecture - which approach to use, how data will flow, what happens when things go wrong. You approve the design before any code is written. You see exactly what you are getting.
We build the integration using AI-accelerated development. You get weekly demos and can test against your real data in a staging environment. Nothing goes live until you have signed off.
We deploy to production with monitoring, alerting, and rollback procedures. Your team gets documentation and training. 30 days of post-launch support is included. You own all the code.
Fixed-price engagements. You know the total cost before we start. No day rates, no surprise billing.
All prices are fixed - you approve the scope before we start. See all our bespoke software development services or book a free discovery call.
Full source code, documentation, and deployment rights. No ongoing licence fees, no vendor lock-in. Your team can maintain and extend the integration independently.
You know the total cost before we start. No day rates, no open-ended billing. If the scope changes, we agree the new price before proceeding - never a surprise invoice.
GDPR-compliant, UK data residency, and security best practices built in. We understand the compliance landscape UK SMEs operate in, from financial services to healthcare.
Straight answers to the questions UK SMEs ask us about system integration.
A single integration between two systems (for example, connecting your CRM to your accounting software) starts from £8,000. Multi-system integrations involving three or more platforms typically range from £15,000 to £30,000. All engagements are fixed-price, so you know the total cost before we start.
Single integrations take 4-6 weeks. Multi-system integrations take 6-10 weeks. Full integration suites with monitoring and AI automation take 8-12 weeks. AI-accelerated development means we deliver in weeks what traditional agencies take months to build.
Yes. We work with the systems you already use - Salesforce, HubSpot, Xero, QuickBooks, Sage, Shopify, WooCommerce, and many others. If a system has an API, we can integrate with it. If it does not, we can often build a custom connector or use middleware to bridge the gap.
Yes, entirely. You own the source code, the integration logic, and all intellectual property from day one. No licence fees, no vendor lock-in, no recurring charges for integrations you have already paid for. Your team can extend and maintain the code independently.
Every integration we build includes error handling, retry logic, and monitoring. If an API changes, we are notified automatically and can fix the integration before it affects your business. Ongoing support is available from £350/month, but you are never locked in - you own the code and can maintain it yourself or with any developer.
