BUSINESS OPERATIONS FOR MICROSOFT 365 · MULTI-TENANT · MULTI-ENTITY
Solver Entra is the business-operations layer above your Microsoft 365 and Entra ID estate — every tenant, every legal entity. It turns raw identity, access and cost data into a business view: one console for how IT is run, and one place where its outcomes are visible to the people who fund and govern it.

THE PROBLEM
Most IT departments run Microsoft 365 competently — identities are provisioned, mailboxes exist, devices are managed — using excellent purpose-built tools: the Microsoft 365 admin center, Entra ID, Exchange admin, and mature third-party reporting products. What none of those tools do is answer the questions a CEO, CFO or COO actually asks:
What does IT cost us, broken down by company and by person?
Who still has access they no longer need?
Are we exposed, and where?
Does onboarding feel the same whether someone joins as an employee, a consultant, or a privileged cloud administrator?
These things are usually the things IT quietly keeps to itself — not out of concealment, but because there has never been a business-legible surface for them. Solver Entra is that surface.
WHAT IT UNIFIES
A single configurable engine standardizing how people get access, however they join, and how that access ends. A hired employee, a consultant and a cloud administrator go through the same governed path.
Visibility into what IT has traditionally kept to itself: unused and unlocked accounts, deviation lists, sharing exposure, and application access across Exchange, OneDrive, SharePoint and other cloud apps.
License spend, cloud application usage and internal/external cost splits turned into monthly, auditable invoice lines per legal entity — including seat-based AI tools.
Every request to change something in the estate becomes a tracked, approvable order, not an invisible ticket or a script run once and forgotten.
Every module reads from the same access and tenant model. A fact captured once — a person's legal entity, their manager, their tenant — is reused in onboarding, in cost allocation and in the security view. IT does not maintain the same organizational structure four times over.
ONE LOGIN, ONE BRAND
Solver Entra is not two products glued together for two audiences. An IT administrator signs in and gets the full operational console. A department manager signs into the same address and gets a scoped view: their own company, their own department, their team's onboarding, offboarding and change requests. An employee signs in and gets a self-service view of their own access, apps and requests. One thing to teach people, and no separate self-service portal to build, secure and maintain.
BUILT FOR GROUPS
Many organizations do not run one Microsoft 365 tenant; they run several — a holding company with subsidiaries each on their own tenant, a group that has grown by acquisition, an IT department running technology as a shared service for many legal entities. Solver Entra is built around a scope-and-subset model for exactly this: a working scope of tenants for the session, and a subset per module, so one administrator sees across the whole estate, a manager is handed exactly the slice that is theirs, and a report can be produced per tenant or consolidated — without switching applications or exporting by hand.
Inside a tenant, Solver Entra recognizes that a tenant is rarely one business either: multiple legal entities share it, each with its own departments, cost center and managers. Delegated administration without delegated risk — a manager can onboard and manage access, scoped strictly to their own legal entity and department. Never the whole tenant. Never another company's people.
THE OPERATIONAL PLATFORM
Administrators see the complete tenant-wide history of every order ever raised, grouped by legal entity, filterable by status and type. A manager sees only their own. Finance rolls the same data up into a cost report.
A user with no manager, an admin account that has not signed in for 21 days, a department name that does not match the reference list — surfaced as a standing list, grouped by which rule was broken.
Cloud application access grouped by app, then by company: a live count, not a request to IT. The same view Invoicing uses to turn access into a cost line per entity.
License assignments, per-user and per-company allocation and cloud application costs become invoice lines each month, grouped by period and company, down to which named application a person's license line is for.
THE BUSINESS CASE
CEO
“How is IT actually run?”
A single, standing view of how the IT organization runs across every company and tenant in the group — no longer a quarterly slide deck assembled by hand.
CFO
“What does IT cost, per entity?”
Defensible, per-entity IT cost — licenses, cloud apps and AI tool usage — turned into invoice lines an ERP can consume, replacing spreadsheet-based cost splitting.
COO
“Is onboarding consistent?”
Onboarding that behaves the same way regardless of who handles it or which business case it falls under — a standardization outcome, not a policy memo nobody enforces.
IT & security leadership
“Where is the risk right now?”
A continuously updated risk register — unused and unlocked accounts, sharing exposure, application access — instead of a point-in-time audit, scoped the way the business already thinks about companies and departments.
One engine, one set of guardrails, regardless of tenant, entity or business case.
Facts that used to live only inside IT become a standing business view.
A new tenant, legal entity or business case is a configuration change, not a re-platforming project.
PLAINLY
Solver Entra is not a replacement for the Microsoft 365 admin center, Entra ID, Exchange admin, or the established third-party reporting and auditing tools an IT department uses day to day. It assumes they exist and keeps using the data and controls that already sit underneath them. It is the layer that makes what those tools already know legible, accountable and actionable at the business level.
OPEN BY DESIGN
Cost data, identity data and orders are never locked inside the product. Any ERP integrates against a documented API rather than a bespoke export — there is no dependency on a specific ERP vendor. Solver Entra also supports MCP (Model Context Protocol), so an organization's own AI assistants can query and act on the platform's data under the same scoped, auditable access model that governs a human user.
