Frequently asked questions

How do you approach legacy system modernisation?

We wrap existing systems with modern APIs and UIs rather than doing full rewrites. This lets you move fast without disrupting operations. We create abstraction layers that allow new features to be built on top of legacy systems while gradually modernising the core.

Can you integrate with our existing ERP and business systems?

Yes. We specialise in system integration with ERPs, CRMs, accounting software, and custom legacy platforms. We work with APIs, EDI, file-based integrations, and build custom connectors when off-the-shelf options do not exist.

How long does a typical UK system integration project take?

Timelines depend on scope. Focused API or workflow integrations often take 2–6 weeks. Larger portal or ERP modernisation projects typically run 2–4 months. We provide a realistic timeline after a short discovery call.

What's included in ad hoc consultation?

Ad hoc consultation sessions cover architecture reviews, technology selection, technical due diligence, or expert input on a specific challenge. You get actionable recommendations and a clear view of scope and approach for potential projects.

Do you only work with UK businesses?

We are UK-based and primarily serve UK SMEs and mid-market B2B companies. Most delivery is remote across the UK, with in-person meetings available in the Midlands when needed.

How do you price system integration and modernisation work?

We offer monthly subscription plans for ongoing delivery capacity, or ad hoc consultation for one-off guidance. Pricing depends on complexity and engagement model — contact us for a tailored quote after a brief discovery call.

What industries do you specialise in?

We work across B2B sectors where legacy systems and operational efficiency matter most: manufacturing, distribution, wholesale, surveillance, and multi-company groups with complex ERP environments.

What technologies do you use for integrations?

We are technology-agnostic and choose tools to fit your stack. Common work includes React, Angular, Node.js, SQL, Microsoft 365/Teams, Open Banking, Twilio, EDI, and custom API layers on top of Progress OpenEdge and similar ERPs.
