System & API Integrations
System & API Integrations
Connect your tools so data flows where it needs to — automatically
Your CRM, ERP, and internal tools shouldn't need manual data entry to talk to each other. We build custom API integrations that automate data flow between your systems and eliminate the spreadsheets in between.
Overview
Your systems should talk to each other.
Most businesses run on a patchwork of tools that don't talk to each other. Customer data lives in your CRM, financial data in your accounting system, and order data in your e-commerce platform — with your team manually copying between them.
We build custom integrations that connect your systems via APIs, webhooks, and middleware. Data flows automatically between your tools in real time, reducing manual entry, eliminating errors, and giving you a single source of truth across your operation.
Whether you need a straightforward two-system sync or a complex multi-platform integration with data transformation, we handle the technical complexity so your team can focus on running the business.
What We Integrate
Connect Everything
CRM Integration
Connect Salesforce, HubSpot, Pipedrive, or custom CRMs with your other business tools so customer data stays consistent and up to date everywhere.
ERP & Accounting
Integrate Xero, Sage, QuickBooks, and other accounting systems with your operational tools — automate invoicing, reconciliation, and financial reporting.
Payment Gateways
Connect Stripe, GoCardless, PayPal, and other payment providers with your ordering and accounting systems for seamless transaction processing.
E-Commerce Platforms
Integrate Shopify, WooCommerce, Magento, and custom e-commerce platforms with your inventory, fulfilment, and accounting systems.
Legacy System Modernisation
Connect ageing systems that lack modern APIs using custom middleware, screen scraping, database bridges, or phased migration strategies.
Custom Middleware & Data Pipelines
Purpose-built data transformation layers that clean, validate, and route data between systems — handling edge cases that off-the-shelf connectors can't.
Our Process
Map, build, test, deploy.
A methodical four-stage process that connects your systems reliably without disrupting your current operations.
- 01
Systems Audit & Data Mapping
We map your current systems, data flows, and integration points. We identify what data needs to move where, and how it needs to be transformed in transit.
- 02
API Development & Configuration
We build custom connectors, configure API endpoints, and develop any middleware needed to handle data transformation and error handling.
- 03
Testing & Data Validation
Every integration is tested with real data scenarios — including edge cases, error conditions, and high-volume loads — before going live.
- 04
Deployment & Monitoring
We deploy with zero downtime, set up automated monitoring and alerting, and provide documentation so your team understands how data flows through your systems.

FAQ
Frequently Asked Questions
If it has an API, we can integrate it. We work with CRMs (Salesforce, HubSpot), accounting tools (Xero, Sage, QuickBooks), e-commerce platforms (Shopify, WooCommerce), payment gateways (Stripe, GoCardless), and custom internal systems. For legacy systems without APIs, we build custom middleware.
A simple two-system integration with well-documented APIs typically takes 2 to 4 weeks. A complex multi-platform integration with data transformation and legacy system connectivity might take 6 to 12 weeks. We scope each project individually.
No. We design integrations to be deployed incrementally with zero downtime. We test with sandboxed environments first, then run parallel systems before cutting over. Your team won't experience any service interruption.
Yes. We regularly work with legacy systems that lack modern APIs. We use database-level integration, custom middleware, file-based transfer, and in some cases screen scraping to connect systems that weren't designed to talk to anything else.
A straightforward API integration typically costs between £3,000 and £10,000. More complex multi-system integrations with data transformation and legacy connectivity range from £15,000 to £40,000+. We provide a fixed quote after the systems audit.
Yes. APIs change, systems get updated, and data volumes grow. We offer ongoing monitoring, maintenance, and support packages to keep your integrations running smoothly. We also provide documentation and training so your team can handle routine tasks independently.
API integration connects two or more software systems so they can share data automatically. Instead of copying information between tools manually, an API lets your CRM talk directly to your accounting software, your website feed orders into your warehouse system, or your HR platform sync with payroll — all without human intervention.
In most cases, yes. Some older systems lack modern APIs, but we can often build custom connectors using screen scraping, database-level integration, file-based exchange (CSV/XML), or middleware that bridges the gap. We assess the best approach during our systems audit and always prioritise reliability and data integrity.
