Resources / Your First 90 Days with an MSP

Your first 90 days with an MSP.

Switching managed IT providers doesn’t have to break your business. Here’s what a good MSP should deliver in weeks 1 through 12, what to expect from your team, and the red flags that predict a bad transition.

The #1 reason businesses stay with a bad MSP is fear of the switch. This playbook exists to show you the switch should be boring — and if it isn’t, that’s a signal about your new MSP.

Week 1–2: Discovery

Your new MSP should learn your environment before touching it. This phase is about them, not you.

  • Kickoff call with leadership — agreed objectives, success criteria, and points of contact
  • Inventory of every workstation, server, network device, cloud account, and line-of-business application
  • Access to your current MSP's documentation (or a plan for creating it from scratch)
  • Review of security posture — MFA status, backup status, endpoint protection, patch status
  • Review of any current or pending compliance obligations
  • Your people shouldn't be doing homework for this phase — the MSP drives it

Week 3–4: Planning

  • Written findings report — what's in place, what's at risk, what they'll change
  • Prioritized roadmap for weeks 5-12 with dependencies called out
  • Fixed monthly cost confirmed in writing; any project-based work scoped separately
  • Transition plan — who owns the hand-off from the old provider, how vendor relationships transfer, what tickets look like during the gap
  • Communication plan for your team so nobody gets caught mid-ticket

Week 5–8: Transition

This is where bad MSPs hide problems. Watch for these specific deliverables:

  • Remote monitoring and management (RMM) agents deployed on every endpoint — you should see a count that matches your inventory
  • Endpoint detection & response (EDR) active on every workstation and server
  • Backup system in place with at least one restore test completed
  • Microsoft 365 (or Google Workspace) admin access transferred cleanly
  • MFA enforced on every user if it wasn't already
  • Your previous MSP's contracts closed out cleanly — documented handoff of licenses, domains, registrar access, DNS
  • First month's invoicing matches what was quoted

Week 9–12: Running

  • Help desk is answering calls from named people, not a general queue
  • A 90-day review meeting with leadership — what's working, what's not
  • Documented incident-response plan with your MSP's name in it
  • Monthly operations report showing ticket volume, SLA adherence, and systems health
  • Quarterly strategy cadence scheduled for the next 12 months

Red flags during the first 90 days

  • Week 1-2 discovery never finishes — scope keeps expanding
  • No written inventory or findings report by week 4
  • Tickets routed to a different rep every time you call
  • Billing doesn't match the quote (either direction — unexpected surcharges OR mysteriously missing line items)
  • MFA deferred "until we get everyone trained" — this is the single biggest tell
  • Backup "in place" but no restore has been tested
  • Your previous MSP's offboarding paperwork never completes
  • Change requests bounce between techs without ownership

What you should be doing, in order

  1. Week 1: introduce the new MSP to your team and list who has what authority.
  2. Week 2: collect your vendor list and hand it over.
  3. Week 4: read the findings report and ask questions until it’s plain English.
  4. Week 6: schedule the first restore test attended by one of your people.
  5. Week 10: hold the 90-day review yourself — not your office manager.
