Switching IT provider: what should a small business check first?

Before switching IT provider, confirm what your business controls, which contracts are involved and how support, security and backups will continue during the handover. Agree the work, responsibilities and tests before setting a firm changeover date. Planning can reduce the risk of disruption, but the work involved depends on your setup.

Start these checks before giving notice. Ending a support agreement may affect services you still need, and different parts of your IT can have different renewal dates.

Be clear about what needs to improve

Write down two or three problems you want the new arrangement to solve. Perhaps staff do not know whom to contact, recurring faults remain unresolved or you cannot get a clear explanation of what is being maintained.

Turn each problem into a question for the prospective provider. For example: “When an issue keeps coming back, who investigates the cause and tells us what happens next?”

This gives you something specific to assess, beyond a reassuring sales conversation. Compare the ongoing service separately from any handover or setup work. Our IT support cost guide explains what to check in a quote.

Check the commitments before giving notice

Gather the agreements for support, Microsoft 365 licences, backups, broadband, phones and any other services supplied through the current provider.

For each one, record:

• The supplier and service covered

• The renewal date and notice requirements

• Any remaining commitment, cancellation or handover charges

• Whether it will stay, transfer or need replacing

Ask about unclear terms before committing to dates. Paying an invoice monthly does not necessarily mean the underlying agreement can end each month.

Keep this list as your handover record. Add a named person and an agreed date beside each action so important jobs do not sit between the two providers.

Confirm business control and access

Ask the current provider to help verify the following, rather than relying on someone's memory:

• Domain name: who is the registered holder, which registrar manages it and who controls renewal and DNS settings?

• Microsoft 365: which organisation account, or tenant, contains your users and data, and how can an authorised person in your business obtain legitimate administrator access?

• Devices and network: what equipment is supported, who owns or leases it, and where is its configuration documented?

• Backups: what is covered, who manages the service, how long information is retained and how a restore is requested?

• Other suppliers: who manages the website, specialist applications, internet connection and telephone system?

Have an authorised business contact demonstrate that they can sign in through the agreed route, and verify access to the recovery methods with the provider. Keep permissions limited to what that person needs; the aim is to establish business control without giving everyone administrator rights.

Keep passwords and recovery codes out of an ordinary handover spreadsheet or email. Agree a secure method for transferring necessary credentials to authorised people.

Switching IT provider: what should the handover include?

Request an agreed handover pack covering the inventory, subscriptions, relevant configuration, supplier contacts and outstanding problems. Include unusual arrangements, such as a scanner that emails documents or an application that relies on a particular computer.

Ask the incoming provider to review the pack and identify missing information before the changeover. Give both providers a named business contact who can approve decisions and resolve questions.

For each protection or backup service being replaced, agree when the replacement becomes active and how it will be checked. If historical backups will not transfer, establish how long they remain available and who can restore from them. Our backup-testing guide explains how to arrange a safe sample restore.

Avoid creating a gap by cancelling the old protection first. Equally, do not assume two management or security tools can run together safely; the providers should coordinate their installation and removal.

Keep Microsoft 365 access and subscriptions separate

A change of IT support provider does not automatically require a new Microsoft 365 tenant or new email addresses. Ask whether your existing setup can remain in place, and why any proposed migration is needed.

There are three separate things to confirm:

1. Administrative access: the permissions a provider uses to manage your environment.

2. Reseller relationship: the arrangement through which a partner supplies Microsoft products.

3. Subscription commitments: the licences, billing terms and renewal dates you have agreed.

Microsoft's partner relationship guidance confirms that removing a partner's admin roles does not remove the partner relationship. Changing who provides support therefore needs a separate conversation about licence supply and billing.

Eligible Microsoft new-commerce subscriptions can be transferred between partners, with both partners agreeing the subscriptions involved. For these subscriptions, a transfer does not start a new cancellation window or reset the remaining subscription term. Ask the incoming provider to confirm the applicable route and remaining commitments. Do not cancel working licences as a shortcut to moving support.

Agree timing, testing and a fallback

Choose a changeover window around your work, including payroll, customer deadlines and staff availability. Ask what could be interrupted, how long the planned work should take and what the team should do if a step fails.

Agree practical acceptance checks. For representative staff, confirm that they can:

• Sign in from the devices and locations they normally use

• Send and receive email, including through shared mailboxes they need

• Open and update the right business files

• Use essential applications, printing and other important equipment

• Contact the new support service successfully

Separately, ask the incoming provider to verify that agreed monitoring, device protection and backups are operating. A working inbox does not prove the rest of the handover is complete.

Record any failed checks, who will fix them and whether the move can safely continue. A fallback might mean delaying a particular change while an existing service stays in place; it needs agreeing in advance.

Hypothetical acceptance record, with invented dates: a small office has passed its agreed support-change checks, but the replacement backup’s sample-restore evidence is missing. A fallback agreed before the handover keeps the existing backup until 20 May, with scope and charges recorded. The business owner’s record reads:

• Support change: accepted.

• Backup change: on hold.

• Outgoing provider: maintain the agreed backup service.

• Incoming engineer: complete a safe sample restore by 14 May.

• Office manager: check that the restored accounts-file sample opens and contains the expected information.

• Business owner: review evidence and approve the backup change on 15 May, or agree a revised plan before the fallback ends.

Both providers confirm the responsibilities, dates and that support can proceed independently. Only the backup change is held; its replacement must pass the agreed checks before the old service is switched off. This separates acceptance of working support from evidence that files can be recovered.

The limited overlap is agreed for this example; it is not assumed to be free or available in every handover.

Close the old access deliberately

Once the agreed checks have passed, coordinate removal of obsolete administrator permissions, remote-access tools and other supplier access. Review any credentials that the outgoing provider knew and arrange appropriate changes.

Check that this will not interrupt services or subscriptions that are legitimately continuing. Record the remaining responsibilities, final billing arrangements and where the business can find its updated documentation.

Tell staff whom to contact from the agreed date. Arrange a short review after the handover to catch issues that only appear during normal work.
