Let me tell you about a revelation I had while building JustPaid. We were watching a CFO spend 3 hours manually matching bank transactions to invoices, cross-referencing PDFs, and updating spreadsheets. That's when it hit me: what if AI could read contracts, generate invoices, and reconcile payments—all automatically?
Today, JustPaid does exactly that. We've built an AI-powered billing platform that uses Claude 3.5 Sonnet and advanced machine learning to automate the entire billing lifecycle. No more manual contract reviews. No more invoice generation headaches. No more payment reconciliation nightmares.
Before JustPaid, here's what B2B companies were dealing with:
One of our customers was spending $200K annually on a team of 3 people just to manage billing. That's insane.
Here's the secret sauce—the actual AI technology we've built at JustPaid:
Upload any contract PDF, and our DocumentExtractor service using Claude 3.5 Sonnet automatically extracts:
Our system automatically creates invoice schedules from contracts. It handles complex scenarios like prorated billing, tiered pricing, and contract amendments—all without human intervention.
Using LangGraph and customizable AI personas, JustPaid sends personalized payment reminders that actually get responses. Our reminder agent adapts tone and timing based on customer behavior patterns.
Let me share what happened when a SaaS company with $10M ARR switched to JustPaid:
Annual savings: $180,000 in labor costs alone. Plus faster collections meant $450,000 more working capital.
Here's what sets JustPaid apart from generic billing tools:
Forget complex implementations. Here's how our customers get up and running:
Total implementation time: 3 weeks. Total hands-on time: About 2 hours.
Here's what our customers are achieving:
At JustPaid, we're not stopping here. Here's what's coming:
AI Chat Assistant: "Hey JustPaid, when will Customer X pay their invoice?" Get instant answers about your billing.
Predictive Cash Flow: Know exactly when payments will arrive based on historical patterns and customer behavior.
Smart Contract Negotiations: AI that suggests optimal payment terms based on customer creditworthiness and your cash flow needs.
Auto-Collections: Graduated collection strategies that adapt based on customer response patterns.
Look, I've been in the trenches with finance teams. I've seen the 2 AM scrambles to fix billing errors before board meetings. I've watched brilliant CFOs waste their strategic minds on manual reconciliation.
That's why we built JustPaid. Not to replace finance teams, but to give them superpowers. Imagine having an AI assistant that never sleeps, never makes mistakes, and gets smarter every day. That's what we've created.
The companies using JustPaid aren't just saving money—they're fundamentally changing how they operate. They're closing books in days instead of weeks. They're predicting cash flow with uncanny accuracy. They're turning billing from a cost center into a competitive advantage.

You closed the deal, celebrated with your team, and then reality hit: custom invoices to create, payment terms to track, and follow-ups to manage. Founder-led sales is powerful because nobody sells your vision better than you do. But the billing aftermath? That's stealing 20 hours a week you could spend building, strategizing, or closing your next customer.
What if your finance team could cut costs, meet ESG goals, and build investor trust—all without adding more work? The era of separating financial performance from sustainability is over. Manual processes weren't built for green finance, but AI-powered automation is transforming finance teams from bottlenecks into sustainability drivers.
Last Tuesday, Sarah from Denver Digital spent 4 hours chasing down overdue invoices. This Tuesday, she spent 15 minutes reviewing automated reports while her AI handled the rest. What changed? She discovered what 91% of mid-sized firms already know: automated accounts receivable isn't just an upgrade—it's a business transformation.
After a decade of building companies and raising millions in venture capital, I've learned that business success often comes down to mastering the fundamentals. DSO measures how long it takes your company to collect payment after making a sale—and it's hiding in plain sight.
Revenue recognition isn't just an accounting checkbox—it's the backbone of financial credibility that can determine whether investors write checks or walk away.
