How to think about resolve unpaid invoices (FixPayment)

Start with the cash-flow math

Unpaid invoices tie up working capital. A $10,000 invoice sitting at 90 days past due isn't just a bookkeeping headache—it's $10,000 you can't deploy toward payroll, materials, or growth. The longer you wait, the more the recovery odds drop. Research consistently shows that invoices over 90 days old have significantly lower collection rates than those under 60 days.

That's why the first question isn't "how do I get paid?" but "what's the most cost-effective path to get paid?" Traditional collection agencies charge 40–45% of the recovered amount. If they collect your $10,000, you keep $5,500–$6,000. That's a steep price for a service that often relies on scripted letters and phone calls.

FixPayment takes a different approach: a flat ~18% success fee, meaning you keep roughly 80% of what's recovered. No recovery, no fee. The difference matters. On that same $10,000 invoice, you'd keep $8,200 instead of $6,000. That extra $2,200 is real margin you don't have to give away.

The AI + human combination

There's a misconception that automated recovery is either robotic or aggressive. Neither has to be true. FixPayment blends AI-driven workflows with human judgment. The AI handles the repetitive, time-sensitive parts—segmentation, follow-up scheduling, document matching, and dispute tracking. Humans step in where nuance matters: negotiating payment plans, mediating disputes, or deciding when to escalate tactfully.

For creditors, this means faster response times without losing the personal touch. An aging receivable at 45 days might get a structured, AI-templated nudge that's still polite and professional. At 90 days, a human negotiator takes over with a clear picture of the debtor's payment history and any documented disputes.

Risk scoring before you extend credit

Prevention beats recovery. The FixPayment FP Risk Score helps you underwrite new clients and monitor existing ones using data that traditional credit bureaus don't always surface. You're not guessing whether a new account will pay—you're seeing a calculated probability based on payment behavior, industry patterns, and historical recovery outcomes.

It's not a magic bullet. No score predicts everything. But when you're deciding between "net 30" and "payment in advance" for a new customer, a risk signal can tip the balance. And when a score drops mid-contract, you have early warning to adjust terms or tighten credit limits.

Flexible resolution paths that protect relationships

Not every unpaid invoice is a deadbeat situation. Sometimes it's a cash-flow crunch on the debtor's side, or a genuine dispute over deliverables. A rigid, confrontational approach burns bridges and often results in partial collections anyway.

FixPayment offers structured payment plans and settlement options. You can accept a lump-sum settlement at a discount, or spread payments over a schedule that works for both parties. The platform documents disputes properly, so if a client claims the work was defective, you have the records to respond factually rather than emotionally.

This is where a collection agency alternative with lower fees shines. Because you're not giving away half the recovery, you can afford to be more flexible. A settlement at 70% of invoice value is a better outcome when you're keeping 80% of that 70% than when an agency keeps 45% of a full recovery.

Tooling for busy finance teams

If you run in-house AR operations, you don't want to log into a separate portal just to check status. FixPayment offers MCP and API tooling that plugs into your existing systems. You can trigger recovery workflows directly from your accounting software, sync invoice data, and pull real-time updates without manual exports.

For larger creditors, this integration makes a measurable difference. You're not chasing spreadsheets or remembering to upload statements. The system does the heavy lifting on documentation and follow-up, and you retain visibility and control.

When to act

The honest answer: earlier than feels comfortable. A 30-day past-due invoice might just be an admin oversight. But by 60 days, the likelihood of collection starts to decline. By 90 days, you're often negotiating from a weaker position.

A practical rule of thumb: escalate to a structured recovery process at 45–60 days. That doesn't mean sending a legal threat. It means initiating a documented, systematic follow-up that signals seriousness without hostility. If the client is responsive and pays, great. If not, you've bought yourself time to recover before the debt ages further.

The cost of waiting is rarely obvious in the moment. But if you've ever written off an invoice that sat too long, you know the real price.
