Choose licenses for the people and work they need to support.
We look at user roles, working patterns, security needs, and who will manage Microsoft 365 before recommending a licensing path.
About ISD Logic
Senior Microsoft 365 guidance for professional firms.
Established in 2007, ISD Logic helps law, accounting, tax, consulting, and other professional firms choose licenses, improve security, plan onboarding or migration, and get ongoing support. A named person reviews the scope with you before any quote, order, access, or change.
What clients can expect
Practical Microsoft 365 advice for a busy firm.
We turn Microsoft 365 licensing, security, onboarding, migration, and support questions into clear choices, responsibilities, and next steps.
Agree on responsibilities before changes begin.
Identity, email, devices, files, sharing, onboarding, migration, and administrative duties are reviewed before approved changes are made.
Keep a named person involved.
A person reviews quotes, orders, access, configuration changes, and support needs with you. Nothing is approved automatically.
How we work
Understand the need before planning the work.
We begin with your business need and current Microsoft 365 setup. We then match the work to Essentials, Secure Work, or Managed Practice and confirm responsibilities before anything changes.
Clarify
Define the firm type, user range, current setup, and the result you need.
Fit
Identify whether Essentials, Secure Work, or Managed Practice is the best place to start.
Scope
Confirm responsibilities, boundaries, timing, price, access, and approvals before work begins.
Support
Handle approved changes and support through a clear service agreement.
Trust boundary
Public first contact stays business-level.
Share only your firm type, approximate user range, current Microsoft 365 status, and the result you want. Do not submit credentials, client matters, patient information, payment information, financial records, or other confidential details.
