Changing IT supplier is one of those decisions businesses put off for far too long. The current provider is not great, response times are slow, the bills feel high, but switching feels risky. What if something breaks during the move? What if we lose data? What if the new supplier turns out to be no better?
These concerns are understandable, but staying with the wrong IT partner costs more in lost productivity, downtime, and unresolved issues than a well managed transition ever would. Here is how to do it properly.
- How to check your current contract and exit terms
- What to document before you hand anything over
- How to manage the transition without downtime
- The questions to ask any new IT supplier before signing
Start with your contract, not your emotions
Before you do anything else, dig out your current IT support contract and read the exit clause. Most contracts have a notice period of 30, 60, or 90 days. Some have auto renewal clauses that lock you in for another year if you miss a window. Finding this out after you have already started talking to a new supplier is a frustrating and avoidable situation.
Check specifically for clauses around data portability and your provider is legally required to give you access to your own data, but the contract may specify the format and timeframe in which they are obliged to do so.
Some IT contracts auto renew annually with only a 30 day window to cancel. If you miss that window, you are locked in for another full year. Check your renewal date before you do anything else.
The transition checklist
A successful switch comes down to documentation and sequencing. Here is the order that works.
- 1Audit what you have. List every system, software licence, domain, hosting account, and piece of hardware your current provider manages or has access to. Do not rely on them to give you a complete list and do your own.
- 2Retrieve your credentials. Get admin access to everything and your Microsoft 365 tenant, your domain registrar, your firewall, your cloud backup. You should always own these. If your current supplier holds them, request them in writing now.
- 3Document your infrastructure. Network diagrams, server specs, software versions, user accounts. The new supplier needs a clear picture of what they are inheriting. If you do not have this, ask your current supplier to produce it as part of your exit.
- 4Run the switch in parallel. Where possible, have the new supplier set up and ready before the old one is off boarded. There should be a brief overlap period where both have access, not a hard cutover on day one.
- 5Communicate to your team. Tell your staff who to contact for IT support from the transition date, what the new process looks like, and who is handling the change. Silence during an IT transition creates panic and shadow IT.
- 6Revoke old access on a fixed date. Once the transition is complete and you have verified everything is working, remove your old supplier's admin access across every system. Do this on a specific, agreed date with written confirmation.
Questions to ask before signing with a new supplier
Not all IT providers are equal, and the sales process rarely reveals the gaps. These are the questions that matter most.
- What is your average response time for a priority one issue? Ask for evidence, not a promise.
- Who specifically will be handling our account day to day? You want a named contact, not a generic helpdesk.
- What does your onboarding process look like? A good supplier has a documented onboarding methodology. If they are vague, that tells you something.
- How do you handle a situation where you cannot fix something? Escalation paths matter.
- What are the exit terms? Yes, ask this before you sign. A confident supplier will not be bothered by the question.
Most IT supplier switches that go badly do so because the outgoing provider was uncooperative, not because the transition was technically difficult. Having a clear, contractually supported exit process protects you from this. Your data and your systems belong to you and not to your IT provider.
