What you actually recover on past due invoices: 18% success fee vs. 40% collection agency charge

Run the numbers on what you keep

Take a $25,000 past due invoice. It goes to a traditional collection agency at a 40% contingency rate. They collect the full amount. You get $15,000. You already delivered the work, and you just absorbed a $10,000 hit on it.

Same invoice through FixPayment's 18% success fee: you net $20,500. That's a $5,500 difference on one invoice. Run 10–15 aging receivables a quarter and the gap adds up quickly. The fee isn't a line item you absorb — it decides how much of your own cash flow stays with you.

I'd argue the fee structure matters more than most credit managers treat it. A lower fee doesn't just save money on the invoices you were already going to work. It changes which invoices are worth working at all. At 40%, a $5,000 invoice may not clear the effort threshold. At 18%, it does.

Why traditional agencies charge so much

Traditional agencies carry real overhead: physical offices, large call centers, and commission structures that push effective rates to 40–45% or higher. A lot of the workflow is still manual, which is slow and inconsistent. That cost lands in your contingency rate.

There's a pricing philosophy issue underneath it too. Agencies price for the worst case — the debtor who won't respond, disputes everything, and drags it out for months. You pay for that risk on every invoice, including the straightforward ones that resolve in two calls.

FixPayment works differently. We use AI to triage and work aging receivables — scoring accounts, drafting communication, and flagging which debts actually need a human. That cuts the manual drag that drives agency costs, and the savings show up in the fee.

No recovery, no fee, but the process is different

Both models are contingent. Nothing collected, nothing owed. The workflow is where they split.

A traditional agency typically opens with a demand letter, escalates to phone calls, then maybe refers to legal. The timeline runs long, and the tone can sour a customer relationship you might want to keep. Sometimes that's the right trade. It's still a trade.

FixPayment blends AI and human touch. The system scores each account with the FP Risk Score, which looks at payment behavior and business signals rather than just a bureau score. From there it assigns a workflow — payment plans, settlements, or dispute documentation — based on what's most likely to close the invoice quickly.

The aim is to resolve unpaid invoices without burning the bridge. You keep more of the cash and, often, more of the customer.

What the 18% fee actually covers

You're not paying someone to call and ask for money. The fee covers a full receivables recovery operation:

• AI-driven account triage and prioritization
• Human negotiators for complex or high-value debts
• Payment plan setup and settlement offers
• Dispute documentation when the debtor pushes back
• MCP and API tooling so you can integrate recovery into your existing AR stack

If you want more control, our API docs let you plug recovery workflows directly into your own systems. You're not handing off the process — you're augmenting it.

When the lower fee changes your decision

Smaller balances often age out because the collection cost eats the recovery. At a 40% fee, a $2,000 invoice nets $1,200. That may not clear the operational hurdle. At 18%, you're looking at $1,640. That difference can flip a write-off decision into a pursue-it decision.

That's the practical value of a collection agency alternative with a lower fee: it widens the set of invoices worth working. Your unpaid invoice recovery strategy can cover more ground without a proportional jump in cost.

It changes forecasting too. If you know you'll keep roughly 80% of recovered amounts, you can model cash flow with more confidence. That helps with planning, not just the recovery event itself.

Compliance without the scare tactics

Some agencies use aggressive language to pressure debtors. It can work short-term, but it builds legal and reputational risk. FixPayment's approach is compliant and measured. We document disputes, follow applicable rules, and communicate professionally. The goal is payment, not intimidation.

For B2B receivables, professionalism tends to get better results. Debtors engage more when they're treated like a business partner who's behind, not a deadbeat. Payment plans and settlements are tools, not threats.

Risk intelligence changes the game

The FP Risk Score deserves a closer look. Traditional bureau scores are built for consumer lending — they don't account for payment patterns, industry risk, or invoice-level behavior. The FP Risk Score does. It gives you a clearer read on which customers are likely to pay late, so you can adjust terms or flag accounts before they age.

That's proactive. Most collection agencies only see the invoice after it's already 90+ days old. FixPayment's risk intelligence is aimed at avoiding that scenario in the first place.
