Welcome to PartnerOne
PartnerOne is a suite of apps for managed service providers (MSPs) and their customers. Instead of one monolithic product, the suite gives each role a focused experience while sharing the same organization, data, and sign-in.
Looking for a specific app? Use the navbar: Suite (overview plus PartnerOne sign-in and Admin), PanelOne (MSP operations), BillingOne (finance), or ClientOne (customer portal). Each product section includes Web app and Mobile app guides.
The suite
| App | Who it's for | What it does |
|---|---|---|
| PanelOne | MSP engineers, service desk, account managers | Unified operations dashboard — clients, devices, alerts, tickets, backups, M365, network, security, documents, and integrations |
| BillingOne | MSP finance and billing teams | Subscriptions, contracts, invoices, reconciliation, missed billing, generated invoices, and revenue analytics |
| ClientOne | Your customers (IT managers, end users) | Self-service portal — devices, tickets, backups, documents, agreements, and optional billing visibility |
Staff sign-in
MSP staff open PanelOne or BillingOne and are sent to PartnerOne sign-in at login.partnerone.dev. Enter your email, then your password, or continue with Microsoft if your organisation has set up Entra SSO. You must set up and use a second factor to access PartnerOne apps — your organisation can't switch MFA off. There is no separate password inside the apps.
See PartnerOne sign-in and Admin for MFA, recovery codes, Entra SSO, invites, passkeys, and the app switcher. Set up staff Entra SSO at admin.partnerone.dev/sso.
Customer sign-in for ClientOne is separate. See Logging in.
Mobile companions
Each web app has a native companion for iPhone, iPad, and Android:
| Mobile app | Pairs with | Best for |
|---|---|---|
| PanelOne Mobile | PanelOne web | Alert triage, device checks, ticket updates, client lookups in the field |
| BillingOne Mobile | BillingOne web | Finance review, draft invoices, missed billing, AR snapshots |
| ClientOne Mobile | ClientOne web | Customers submitting tickets, checking devices, signing agreements |
Each mobile app requires iOS 17.0 or later (iPhone and iPad) or Android 8.0 or later. Public store listings are not published yet — use the install method your organization or IT provider gives you. Sign in with the same account as the web app. BillingOne Mobile and ClientOne Mobile have fewer features on Android than on iOS; PanelOne Mobile matches on both.

- PanelOne is the operational source of truth for clients, devices, and integrations.
- BillingOne consumes normalized billing data from the same organization.
- ClientOne exposes a curated subset to each customer, controlled by your MSP in PanelOne (ClientOne admin).
PartnerOne Admin has an app switcher; other products may add their own launcher. See App switcher.
