Freelancer & Contractor Debt Recovery

When a US Client Won't Pay a Freelance Invoice

Hammer Worldwide helps freelancers and independent contractors recover unpaid invoices from US business clients — on contingency, no cost unless we collect.

Do I need a formal contract to have a case?

No — a written scope agreed by email, WhatsApp, or message, before the work started, is generally enough. What matters is that the price and work were agreed in writing, not the format.

What's the strongest kind of claim?

One clear invoice for specific, delivered, undisputed work — not a running balance built up over many months. If you're unsure which yours is, describe it and we'll tell you honestly.

Does it matter where I'm based?

No. What matters is that your client is a US business. We work with freelancers based in the US and internationally.

What if I only have WhatsApp messages, not a formal invoice?

That's usually enough to start. Payment promises, acknowledgment of the work, and agreed pricing in writing all count as evidence.

Is there a minimum claim size?

Generally $3,000 and above, though larger claims closer to $8,000 and up are the strongest fit.

What if my case is messy — a running balance, an unclear company structure, no formal contract?

Many collection tools and agencies only take clean, single-invoice, undisputed claims. If yours doesn't fit that mold, that doesn't mean nothing can be done — it often just means you haven't found someone willing to actually look at it. Tell us the details and we'll give you an honest read.
