If your team is growing faster than your IT capacity, sooner or later someone asks the question: should we hand part of this to a managed IT service provider (MSP)? The answer is often yes, but the hard part is choosing well. A bad fit costs months of migration work and a lot of trust.
This is the checklist I would use as an engineer or IT lead to compare providers before signing anything.
1. Start with what you actually want to hand over
Write down the work, not the vendor category. For example:
- Endpoint management and patching for 120 laptops
- 24/7 monitoring and alerting for production servers
- Backup, restore testing and disaster recovery
- Identity and access management (onboarding, offboarding, MFA)
- Help desk for non-engineering staff
A provider that is great at help desk may be weak at infrastructure monitoring. A clear scope stops you comparing apples with oranges.
2. Check how they handle security, not just what they say
Ask for specifics:
- Which security frameworks do they work to (for example SOC 2, ISO 27001, NIST CSF), and can they show a current report or certificate?
- How do they manage their own privileged access to your systems? Shared admin accounts are a red flag.
- What is their incident response process, and how fast do they tell you when something goes wrong?
If you are in a regulated industry (healthcare, finance, government contracts), confirm they have run engagements under the same rules before.
3. Read the SLA like a contract, because it is one
Look for:
- Response time and resolution time, defined separately
- What counts as a priority 1 incident
- Service credits if they miss targets
- Hours of coverage and what "24/7" really means (people, or just automated alerts)
4. Ask about tooling and lock-in
Good questions:
- Which RMM, PSA and monitoring tools do they use?
- Will you keep admin access to your own tenant and accounts?
- How is documentation handed over if you leave?
You want a provider that makes leaving easy. Paradoxically, those are the ones teams tend to keep.
5. Talk to two or three current clients
Ask for references that look like you: similar size, similar stack, similar industry. Ask them what went wrong in the first 90 days and how the provider handled it.
6. Compare more than three providers
Most teams shortlist the first three names they find. It is worth looking at a wider set by region, specialization and size first.

7. Run a small pilot
Before moving everything, hand over one contained piece of work for 30 to 60 days (for example patching or backup checks). Measure response times, ticket quality and how well they document. A pilot tells you more than any sales call.
Quick checklist
- [ ] Scope written as tasks, not categories
- [ ] Security frameworks verified with documents
- [ ] SLA reviewed: response, resolution, credits, coverage
- [ ] Admin access and documentation stay with you
- [ ] Two or three references from similar clients
- [ ] Wider shortlist compared, not just the first three names
- [ ] 30 to 60 day pilot before full handover
Choosing an MSP is a long-term relationship. A week of structured checking up front saves a painful migration later.
