How to think about FixPayment 18% success fee (FixPayment)

The fee structure most B2B teams accept without questioning

Traditional collection agencies work on contingency, usually somewhere between 30% and 50% of what they recover. Run that against a $50,000 invoice and you might hand over $20,000 or more. If the margin on that sale was thin to begin with, the fee can eat most of it.

Those agencies often lean on pressure because their revenue depends on volume and speed. That can cost you a customer you wanted to keep, and it can create compliance exposure if the communication crosses a line.

FixPayment runs a flat ~18% success fee. You keep roughly 80% of every dollar recovered. It's not a teaser rate or a first-month discount — it's the standard structure.

Why a lower success fee makes sense for everyone

An 18% fee forces you to be selective. You can't afford to work every stale receivable with a generic script. So the work leans on a mix of AI-driven triage and human judgment: which accounts are likely to pay, how they prefer to be contacted, and what resolution actually fits.

For you, the math is simple. A $25,000 unpaid invoice at a 40% agency fee leaves you $15,000. At 18%, you keep $20,500. That extra $5,500 stays in your operating budget.

The fee is contingent, so no recovery means no fee. Our interest and yours line up: we get paid when you get paid.

How AI and human workflows keep the fee manageable

A lower fee doesn't mean less effort — if anything it means the effort has to be better targeted. We use AI to sort aging receivables, score each account on payment history and behavioral signals, then route it to the right workflow. Some accounts just need a payment plan. Some need evidence of the debt and a clear timeline. A few need a settlement offer.

Our FP Risk Score gives you a read on a debtor's likelihood to pay before you even send a claim. It's not a consumer bureau score. It pulls from commercial data, payment patterns, and public records so you can decide whether to pursue a claim or write it off.

Less time goes to accounts that won't pay, more goes to the ones that will. That efficiency is part of why the fee can sit at less than half of a typical agency's cut.

What you actually get for the 18% fee

Here's what the fee covers, without the mystery.

• Compliant communication: We follow commercial debt collection rules. No threats, no harassment, no gray-area tactics.
• Dispute documentation: If a customer disputes the invoice, we gather delivery confirmations, contracts, and email trails to build a defense.
• Payment plans and settlements: We structure arrangements that work for both sides, so you get paid without backing the debtor into a corner.
• Reporting and transparency: You can see where each account stands through our portal or via API integration if you want to automate the flow.

That last point matters if you're running hundreds of invoices. Chasing status updates by email doesn't scale. Pulling the data into your own systems does. Our API and MCP tooling are built for that.

When the 18% fee is worth it, and when it isn't

No fee structure fits every receivable. A $500 invoice against a debtor who's clearly insolvent probably doesn't justify the effort at any percentage. For most B2B receivables above that threshold, the math tends to work.

Quick way to frame it: take the invoice amount, subtract your cost of goods or service delivery, then subtract the 18% fee. If the net recovery still beats writing the invoice off or selling it to a factor, it's worth pursuing.

Say you have a $10,000 invoice with $7,000 in direct costs. Writing it off puts you at break-even. Recovering at 18% gets you $8,200, which is $1,200 better than break-even. That's real cash flow relief.

We also help you decide which accounts to send. Our unpaid invoice recovery page covers how to spot accounts that are good candidates, so you're not paying fees on lost causes.

Comparing FixPayment to a traditional collection agency

If you're used to a 40% contingency, 18% can sound too good to be true. The difference is the model. Traditional agencies spend heavily on call centers and legal threats. We spend on data, automation, and training our team to resolve disputes without escalation.

That doesn't mean we're softer. It means being more deliberate about when to push and when to negotiate. The goal is the same — get your cash flow moving — but the approach is more surgical.

If keeping the customer relationship matters to you, that distinction carries weight. A customer who pays after a respectful but firm process is more likely to order again than one who feels bullied.

The bottom line on the 18% success fee

You don't have to accept 40% to 45% as the cost of doing business. The FixPayment 18% success fee is a workable alternative for B2B teams that want to keep more of what they recover without giving up compliance or effectiveness.

Run the numbers on your own aging receivables. If you're looking at a 40% fee today, moving to 18% means you keep an extra 22 cents on every dollar. On $100,000 in recoverable debt, that's $22,000 back in your pocket.

That's not hype. That's arithmetic.
