Websites built around how your business works, scoped after a discovery conversation.

Hosting oversight, updates and agreed changes for the website you rely on.
Explore Website CareIt is a free 30-minute call with a person. The call confirms your business requirements, Microsoft 365 user count, current licences, backup arrangements, devices, existing IT-provider relationship and which OneOfZero service may suit you. No tenant access, audit or technical assessment takes place during the Fit Call.
Pricing depends on your users, devices, licence commitment and support requirements. We confirm it in writing after the Fit Call, before you agree to anything.
Not for the Fit Call or the Readiness Check. A Resilience Review or managed plan needs access to your tenant, and written authorisation is required before any tenant access.
It depends on your plan. Essentials covers licence administration, limited user onboarding and offboarding, and standard Microsoft escalation assistance. Secure & Recover adds fair-use Microsoft 365 support and quarterly service reviews. Managed Workplace adds device enrolment, broader fair-use remote IT support, prioritised support within the service terms agreed in writing, and a quarterly technology review. Support covers reasonable day-to-day requests within your plan. Fair-use limits, service boundaries and response expectations are set out in your agreement. Support is not unlimited.
In 30 minutes we talk through your users, licences, backup, devices and current IT support, and tell you which service may suit you.
No pressure and no obligation. No tenant access, audit or technical assessment takes place during the Fit Call.
