JustPaid (Loopfour Inc)

We make it easy for founders to do billing right out of demo day.

Every B2B startup faces the same billing nightmare: unique customer terms, custom pricing, usage tiers, and discount structures that make manual billing a costly mess. Hiring billing specialists adds overhead and introduces human error right when you need to move fast.

JustPaid makes billing effortless by extracting billing logic directly from your contracts—whether they're PDFs or stored in your CRM—and automatically generating accurate, timely invoices.

Already using Stripe, DocuSign, CommonPaper, HubSpot, or Salesforce? We integrate seamlessly with your existing stack.

Our robust API lets you maintain control while automating the complexity. No more pricing disputes. Faster cash flow. Fewer headaches.

- Move fast: Bill customers from day one without hiring specialists
- Scale smart: Handle complex pricing models without operational overhead
- Stay focused: Spend time building your product, not managing invoices
- Reduce risk: Eliminate human error in billing calculations

We're always asking ourselves: How can we make a company's financial operations effortless so teams can focus on scaling?

- We don't settle
- We are passionate
- We are serial entrepreneurs

We aim to make a dent in the universe.
