How Do You Select an Integration Provider in the UK?
Quick Summary
To select an integration provider, first write down which systems must connect, which data must move and how often, and what breaks today. Then score each provider against the same criteria, including technical depth, security, support model, documentation and scalability. Finally, ask how they handle outages, API changes and rollbacks before you commit.

How Do You Select an Integration Provider in the UK?
Last Updated: 29 October 2026
What an Integration Provider Actually Does
Choosing the wrong integration provider is one of the most expensive mistakes a growing business can make. The pattern is familiar to many organisations: the software stack has grown faster than anyone planned, and nobody owns how the pieces talk to each other.
An integration provider is the firm that connects your systems so data moves between them without manual re-keying. That might mean linking your accounts package to your CRM, syncing a practice management system with a payroll platform, or building the connectors that keep your Microsoft 365 environment talking to line-of-business tools.
According to Merge (2026), citing Gartner, 39% of organisations cite integrations as the most important factor when selecting a software provider. That makes integration capability a buying criterion, not an afterthought. Merge's 2026 integration statistics, citing Gartner
Integration work sits between software vendors and your internal IT. A good provider owns the connections, documents them, monitors them, and fixes them when an upstream update breaks a workflow.
Defining What You Need Before You Shortlist
Most selection processes go wrong before the first vendor call. Teams start comparing providers without agreeing on the problem.
Write down three things before you talk to anyone: which systems need to connect, which data must move and how often, and what breaks today when it doesn't. Our guide on how to choose professional services software integration solutions walks through defining these needs. A list of twelve systems matters less than knowing that invoices are re-typed every Friday and that is costing someone half a day.
Be honest about who will maintain the result. Integrations rarely fail on day one. They fail six months later, after a vendor changes an API, and by then the person who built the workflow has left.
Criteria for Evaluating Integration Providers
Once you know the problem, score each provider against the same criteria. Rate each on a simple scale so the comparison stays fair.
| Criterion | What to check | Red flag |
|---|---|---|
| Technical depth | Experience with your specific platforms | Generic "we can connect anything" claims |
| Security practice | Documented controls, access management | No answer on how credentials are stored |
| Support model | Named contacts, response targets | Ticket-only support with no escalation route |
| Documentation | Written records of every integration | Logic that lives only in one engineer's head |
| Scalability | Handles more users and tools without a rebuild | Priced per connection with no volume plan |
| Local presence | Ability to meet on site when needed | Entirely remote with no local accountability |
Ask for references from businesses of a similar size and sector. Our guide to choosing a cybersecurity provider in Leeds covers comparing providers on location, experience and technical expertise. Ask what they would change about the relationship. Vague answers are informative.
Check whether the provider is part of a recognised assurance scheme. For UK businesses, Cyber Essentials and Cyber Essentials Plus are the government-backed baseline to look for, and Hamilton Group holds Cyber Essentials Plus certification as a Certified Partner.

Questions to Ask an Integration Provider Before You Commit
The answers to these questions separate providers who fix problems from those who log tickets and disappear.
- Who answers the phone when something breaks at 4pm on a Thursday?
- What is your target response time, and what happens when it's missed?
- Who owns the integration documentation, and do we receive a copy?
- How do you handle a vendor API change that breaks a live workflow?
- What exactly is included in the monthly fee, and what triggers an extra charge?
- How do you add a new user or tool without a full rebuild?
- How long does a migration take, and how is downtime avoided during cutover?
- What is your backup and rollback plan if a change goes wrong?
Hamilton Group's approach is built around these questions. Our guide on choosing an IT provider in Leeds sets out ten questions that reveal quality, covering response times, SLAs and support quality in detail. Our proactive IT management resolves issues in under 15 minutes.

Checking Systems Integration Security
Every integration is a new route into your data. A connector with broad permissions, or stored credentials that never rotate, can become the weakest point in your estate.
Ask how the provider manages service accounts, whether they use least-privilege access, and how credentials are stored and rotated. Ask what logging exists so you can see which system accessed which data and when.
Security should be a baseline, not an upsell. If you are a regulated business, our overview of advanced cyber security explains what that means in practice.

Many businesses find that integration security gaps only surface during a certification assessment or an incident. Asking the question upfront is far cheaper.
iPaaS Providers UK: When a Platform Is the Right Fit
An integration platform as a service (iPaaS) is a cloud tool that provides pre-built connectors and workflow builders. For some businesses it is the right answer. For others it adds cost and another system to maintain. Deciding whether to build internal capacity or outsource these technical requirements necessitates a rigorous approach to evaluating managed IT providers to ensure long-term operational stability.
An iPaaS suits organisations connecting a handful of common SaaS applications with standard data flows. It becomes harder to justify when your workflows are bespoke, when you rely on legacy on-premises systems, or when nobody in-house has the skills to maintain the platform.
Be wary of any provider who recommends a platform before understanding your processes. The right answer depends on the problem you defined earlier, not on the tool a vendor happens to resell.
Your Integration Provider Checklist and Next Step
Use this checklist to keep your shortlist honest:
- The problem, systems and data flows are written down
- Each provider has been scored against the same criteria
- Security practices are documented and understood
- Response times and escalation routes are in writing
- Pricing covers exactly what is and isn't included
- Migration and rollback plans are explained step by step
- At least two references from comparable businesses have been checked
If you are in Yorkshire and want a clear answer to these questions, Hamilton Group can review your current systems and tell you plainly what needs connecting and what it should cost to maintain. Pricing depends on your user numbers, systems and support level, so contact us or visit our website for a current quote.
Frequently Asked Questions
What does an integration provider do?
An integration provider connects the software your business already uses so that data moves between them without manual re-entry. This might mean linking your accounting package to your CRM, or syncing a booking system with your invoicing tool. Good providers also document how the connections work, monitor them for failures and fix them when they break. Before hiring one, confirm whether they build custom connections, use off-the-shelf connectors, or do both, because that affects cost, flexibility and how easily you can change systems later.
How do I choose the right integration provider for my business?
Start by listing the systems that need to talk to each other and the problems you want solved, such as duplicated data or downtime. Then shortlist providers with experience in those specific platforms and in businesses of your size. Ask for references, check how they handle support and outages, and compare how they price changes. Pricing depends on the number of connections, the volume of data and how often the setup changes, so request a written quote based on your own requirements rather than relying on a generic figure. Visit the provider's website or contact them directly for current pricing.
How can I check whether an integration provider is secure?
Ask whether the provider holds Cyber Essentials or Cyber Essentials Plus certification, which is a UK government-backed scheme run by the National Cyber Security Centre. Ask how they store credentials, whether they use least-privilege access, how they monitor connections and how quickly they respond to incidents. Also ask whether they will sign a data processing agreement that meets UK GDPR requirements, since personal data passing through integrations is covered by that law.
What is the difference between an integration provider and an iPaaS provider?
An integration provider is a service business that designs, builds and maintains connections between your systems. An iPaaS (integration platform as a service) is a software platform that lets you or a provider build and run integrations in the cloud. Many integration providers use iPaaS tools behind the scenes. If you have in-house technical skills and simple needs, a platform may suffice; if you need ongoing support and accountability, a managed provider is usually the better fit.
