What is The One Stack?
The One Stack is the complete MSP operations platform — 31 products built from the ground up to work as one unified system. Built by The One Family LLC, it replaces the patchwork of disconnected tools that MSPs typically rely on with a single, integrated platform.
Who is it for?
- MSP owners and leadership — Run your entire business from one platform with unified billing, reporting, and client management.
- Technicians — Work tickets, manage endpoints, monitor security, and communicate with clients without switching between a dozen apps.
- MSP clients — Access a branded client portal to submit tickets, view reports, and manage their own users.
The Product Ecosystem
The One Stack organizes its 31 products into five layers:

How Products Connect
Every product in The One Stack connects through two shared systems:
- Hub is the identity center. One login (Microsoft Entra SSO) gives you access to all 31 products. Hub manages organizations, users, roles, and the 640+ permissions across the platform.
- The One Bus is the event backbone. When something happens in one product (a ticket is created, a device goes offline, an invoice is paid), the Bus broadcasts that event so other products can react in real time.
This means your CRM knows when a PSA ticket is resolved. Your Books invoicing knows when time entries are logged. Your Defend alerts create PSA tickets automatically. Everything stays in sync without manual data entry or brittle integrations.
Why a Unified Platform?
MSPs today typically run 8–15 separate tools: a PSA, an RMM, a backup product, an email tool, accounting software, a CRM, and more. Each has its own login, its own data silo, and its own billing.
The One Stack replaces all of them:
- One login — Microsoft Entra SSO across every product
- One bill — Unified billing through Books, not 15 separate invoices
- One data model — Clients, contacts, and devices are shared across products, not duplicated
- One AI — Jarvis (Cmd+J) works everywhere with context from every product
- One price — Bundled pricing instead of per-tool licensing that adds up fast
The result is less context-switching, less data re-entry, fewer integration headaches, and a platform that gets smarter the more you use it.
