Getting Started with BillingOne
BillingOne is PanelOne's dedicated billing and finance interface. PanelOne is where your MSP connects and operates its RMM, security, M365, marketplace, domain, and PSA data. BillingOne is where finance turns that trusted source data into contracts, quantities, invoices, reconciliation, and revenue analytics.
BillingOne is part of the PartnerOne suite. See the suite overview.

Accessing BillingOne
There are three ways to get to BillingOne:
| Method | How |
|---|---|
| Direct URL | Navigate to app.billingone.dev |
| Cross-app navigation | Use the app switcher in PanelOne's header |
| URL parameter | Add ?app=billingone to your PanelOne URL |
PanelOne and BillingOne share the same credentials and organization. On production hosts, the app switcher uses a one-time session handoff so you usually won't re-enter your password; MFA may still apply on the other host. Passkeys are per hostname — a key for app.panelone.dev does not unlock app.billingone.dev. For full cross-app behavior (localhost, handoff failures, MFA), see BillingOne — Accessing BillingOne.
Signing In
- Go to BillingOne (see methods above)
- Enter your email address
- Click Continue
- Enter your password
- Click Sign In
You use the same credentials as PanelOne — there's no separate account.
First-Time Setup
When you first access BillingOne, the onboarding wizard helps you set up:
- Create your organization (if not already done in PanelOne)
- Select billing integrations — Choose billable sources such as Pax8, Xero, QuickBooks, and/or Synergy Wholesale (for Domains & Hosting)
- Review your profile
- Complete setup
If you've already completed onboarding in PanelOne, BillingOne will use the same organization.
For RMM, security, M365, and other operational sources, connect those providers in PanelOne. BillingOne does not replace your RMM; it relies on PanelOne to normalize those sources into billable data.

Switching Between Apps
To go back to PanelOne from BillingOne:
- Use the cross-app navigation link in the header
- Navigate directly to
app.panelone.dev
On production, the app switcher uses a one-time session handoff between app.panelone.dev and app.billingone.dev. MFA may still be required. If handoff fails, sign in at /auth with your PanelOne credentials. See BillingOne — Accessing BillingOne.
Next Steps
- Connect Pax8 — Set up your subscription data source
- Connect Xero or QuickBooks — Set up ledger sync for generated invoice push and accounting snapshots
