What to check before you buy
Questions to answer, ideally during a free trial or a demo, before you commit:
- Which business plan includes the security you need.
- Admin skills required.
- Licensing as you grow.
- AI (Copilot) add-on costs.
- US tax and compliance. Software doesn't replace professional advice on payroll, sales tax or industry rules.
- Getting your data out. Ask how you would export your data if you ever switch.
Pricing
Microsoft 365 pricing depends on the plan, number of users and add-ons, and vendors change it often. We don't list prices on overview pages; check the current plans on the official Microsoft 365 website. Our full review will break down the real cost.
