White-label billing for MSPs

Your clients’ billing portal.
Your brand. Not another vendor.

MSP Porter is the invoicing, quoting, and payments portal your managed-service clients log in to — on your domain, in your colors — while it quietly keeps QuickBooks and Stripe in sync behind the scenes.

Everything billing, one portal

Requests, quotes, contracts, invoices, and payments in a single client-facing surface — with the accounting plumbing handled for you.

Client portal

A billing portal in your brand, not ours

Every client signs in to a portal on your own domain, with your logo and colors. They see invoices, pay, pull receipts, and request new services — and never learn we exist.

Billing engine

Invoices that live in the portal

Build invoices line by line or straight from a contract. Figures are exact-to-the-cent, net terms are yours, and nothing is a spreadsheet.

Payments

Client-authorized card & ACH

Payments move only when a client presses pay, or via autopay they set up. Card surcharging and ACH are built in on top of Stripe Connect.

Requests & quotes

From client request to signed contract

Clients request new services right in the portal, landing in a triage queue you turn into quotes. Quoter proposals sync in, DocuSign envelopes attach on signature, and an accepted quote promotes to a live contract in one click.

Accounting

Write-through to QuickBooks

Portal invoices and payments queue to your books so QuickBooks stays the source of truth — no double entry, no month-end reconciliation marathon.

Isolation

Every tenant walled off

Row-level security on every table and one audited data path mean one MSP can never see another's clients, invoices, or margin. Multi-tenant, done right.

Live in three steps

Self-service onboarding walks you the whole way — no implementation call required.

Built for money and multi-tenancy

Isolation and payment integrity aren’t features we bolted on — they’re the architecture.

Row-level security

Every tenant-owned table enforces isolation at the database, through one audited access path.

Client-authorized payments

Money moves only from a portal pay flow or autopay — never from a stray API call.

Exact cents

All figures are integer cents end to end. No floating-point drift, ever.

Secrets stay secret

Credentials live in a secrets store — never committed, never logged.
