A lot of firms stay with poor IT support longer than they should. Not because they are happy, but because changing provider feels riskier than putting up with slow responses, recurring issues and vague accountability. That is exactly where parallel run IT support becomes useful. It gives you a practical way to compare IT providers and test service quality in real working conditions before committing to a full switch.
For accountancy practices, solicitors and other professional services firms, the hesitation is understandable. Your systems are tied to client work, compliance, document handling and day-to-day deadlines. If email access drops, Microsoft 365 permissions are wrong, or a line-of-business application stops working, the impact is immediate.
The question is not whether a new IT company can sell well. It is whether they can actually support your business reliably when something goes wrong.
What parallel run IT support actually means
Parallel run IT support means your current IT provider remains in place while a second provider supports agreed users, systems or service areas alongside them. Rather than switching everything in one move, you compare IT providers in a controlled and practical way.
That comparison might focus on first-line support for a set number of users, Microsoft 365 administration, cyber security oversight, backup reviews, or handling selected day-to-day issues. The scope depends on what you want to test.
You are not relying on promises. You are observing how support works when your business is busy and the pressure is real.
Why firms ask about parallel run IT support
Most businesses do not start looking because they want change for its own sake. They start looking because the current arrangement is not giving them confidence.
Sometimes the issue is response time. A member of staff reports a login problem at 9am and still has no meaningful update by lunchtime. Sometimes the provider fixes symptoms but never addresses the underlying cause, so the same printer, Wi-Fi or Outlook issue keeps returning.
In other cases, directors are not sure whether security, backup and access controls are actually being managed properly.
That creates an awkward position. You may suspect the service is not good enough, but you do not want to switch IT provider blindly and find out too late that the replacement is only marginally better.
Parallel run IT support gives you a safer route. It reduces the decision from a leap of faith to a comparison based on evidence.
Parallel run vs switching IT provider outright
A full switch is faster, but it carries more risk. You are committing before you have seen how the new provider performs in practice.
A parallel run is slower, but it gives you visibility. You can compare IT providers based on real support requests, communication quality and issue resolution before making a decision.
For most SMEs, especially those handling client data or working to tight deadlines, the ability to switch IT provider safely is more valuable than speed alone.
Where a parallel run works best
A parallel approach is particularly useful when your business depends on steady access to systems and documents.
That is why it tends to make sense for firms handling confidential client data, high email volumes and structured workflows.
For example, an accountancy firm may want to test how a new provider handles Microsoft 365 user management, password resets and device issues during a busy reporting period.
A solicitor’s practice may want reassurance that document access, permissions and staff support requests are dealt with carefully and quickly.
An office manager in a growing SME may simply want proof that calls are answered promptly and technical explanations are clear enough for non-technical staff.
The aim is not transformation. It is confidence.
How to compare providers during a parallel run
A useful parallel run is structured. If it is too vague, you will end up with opinions rather than a clear basis for decision.
Start with the problems you are already experiencing. If response times are poor, measure response times. If communication is the issue, assess how updates are given and whether users feel informed.
If you are concerned about resilience or data protection, include specific checks around areas such as backup coverage and security controls:

You also need to define scope early. If both providers are active, everyone should know who is responsible for what. That avoids confusion and prevents issues from bouncing between suppliers.
A sensible comparison focuses on:
- speed of response
- quality of resolution
- clarity of communication
- control over systems and changes
For many firms, this is where a structured trial IT support approach or parallel run becomes the most practical option. It allows you to compare IT providers without committing to a full switch and gives your team direct experience of how support actually works day to day.
What a good parallel run process looks like
The best parallel run IT support arrangements are controlled without being disruptive.
The process usually begins with discovery. The incoming provider needs to understand your current setup, key systems and main pain points.
Then support boundaries are agreed. This might include a defined user group, specific types of issues, or Microsoft 365 administration.
During the trial, service should be tracked in a way that is easy to review. You are looking for patterns, not isolated incidents.
At the end, the question is simple. Did support improve in a way that matters to your business?
The trade-offs to consider
Parallel run support reduces risk, but it is not completely effortless.
The first consideration is clarity. If roles are not well defined, staff may be unsure who to contact.
The second is access. A meaningful trial requires enough access for the new provider to support users properly.
The third is time. A very short trial may not show enough. A very long one can become inefficient.
There is also a practical factor. Some existing providers cooperate with a parallel run. Others do not. That makes structure and clear ownership even more important.
Signs the new provider is genuinely better
A better IT support partner is not just quicker to answer the phone.
Users stop chasing updates because communication is consistent. Repeat issues reduce because root causes are addressed properly. Systems such as Microsoft 365 are managed in a more structured and controlled way.
Security conversations also become clearer, with practical recommendations rather than vague reassurance:

You may also notice a shift internally. Staff raise fewer complaints. Managers spend less time chasing support issues. Decisions become easier because advice is clear and grounded in how your business operates.
Good support removes friction. It does not create more of it.
When to move from trial to full switch
A full move should happen when the evidence is clear enough that staying put feels like the greater risk.
That might be because the new provider consistently performs better. It might be because they have identified gaps that need proper ownership. Or it may simply be that your team trusts them more.
For many SMEs, the safest way to switch IT provider is not to wait until things are failing. It is to compare IT providers while the business is stable enough to make a calm decision.

Better decisions come from evidence
Most firms do not need dramatic IT change. They need fewer recurring issues, clearer communication and more confidence that the basics are under control.
If you are already questioning whether your current support is good enough, the next step is not to guess.
It is to compare IT providers in a controlled way, test how support works in practice, and only switch when the evidence is clear.
