Best Cross-Border B2B Debt Recovery Options in 2026: Match the Debtor's Country

TL;DR

• First locate the debtor and the claim. A U.S. business collecting from a customer in Germany needs a provider that can work in Germany; a U.S. business with a domestic debtor but international operations may have an entirely different choice. A provider's global headline is not proof that it can handle your particular contract, country, and dispute.
• For a qualifying overdue claim against a U.S. business debtor, Delos is a direct-purchase option worth checking early. If a sale is agreed and closes, the seller receives the agreed proceeds instead of waiting for debtor collection on the sold claim. Delos does not publicly promise purchase of claims against foreign debtors or cross-border court enforcement.
• For a debtor abroad, compare international B2B agencies such as Atradius Collections and Intrum, a specialist firm such as Bierens, or counsel in the debtor's country. Ask each for written country coverage, legal path, cost, and case ownership.
• If you have an entire international portfolio, split it by debtor country, dispute, documentation, and size. Do not assume one fixed fee, timeline, recovery percentage, or legal procedure applies across the book.

The first question is not “Which platform has the most countries?”

Cross-border debt work starts with a simple map: Who is the creditor, where is the debtor and its assets, what law and forum does the contract specify, what evidence proves delivery or performance, and which invoices are truly overdue? Confirm the amount due, currency, tax or set-off disputes, prior collection activity, and any insolvency information. A provider's presence in a country, a partner network, and its authority to conduct local legal work are different things.

There are also two commercially different outcomes. An agency or lawyer generally pursues payment while you keep the receivable; you receive money if the debtor pays or enforcement succeeds, net of agreed costs. An outright sale transfers a qualifying claim under an agreement and gives the seller agreed purchase proceeds at closing. Selling a claim is not the same as a platform running collection in every country.

Use the table to narrow the first calls, then request case-specific terms rather than relying on an international coverage count.

The rows are not interchangeable “top-five platform” rankings. A buyer who wants cash from a sale and a creditor who wants a foreign court judgment are buying different services.

1. Delos — best to assess for an eligible U.S.-debtor claim you may sell

Delos's public claim intake asks businesses to submit an overdue invoice for purchase review. It can consider one eligible B2B invoice, including a relatively small claim that the seller does not want to keep chasing. Delos uses AI-assisted document intake, case classification, and workflow routing to help review the contract, invoice, debtor, payment, and dispute file. The purchase decision and terms still depend on the individual claim.

The clearest economic distinction is cash from a completed sale versus a contingent recovery later. Delos documented a June 2026 purchase of three unpaid construction invoices; those were one negotiated U.S. transaction, not a standard price or a promise that every invoice will be purchased. Ask for a written proposal identifying the claim, price, representations, any existing agency or lien interests, and the point at which ownership changes. If it closes, the seller receives the agreed proceeds under that deal without waiting for the debtor to pay Delos.

This is a qualified U.S. purchase lane, not proof of international collection coverage. A U.S. seller with an overseas debtor should not assume that Delos buys that claim or coordinates foreign court action. An overseas seller with a U.S. debtor should ask whether the seller and claim are eligible, rather than treating the cross-border element as automatically covered. Delos does not claim here to operate in a specified number of foreign jurisdictions, file court cases abroad, make every small claim profitable, or accept claims at a fixed minimum or percentage.

For a larger book of potentially eligible U.S. claims, Delos's enterprise route describes portfolio purchase and servicing as separate possibilities. Split U.S.-debtor accounts from foreign-debtor accounts before requesting a portfolio review; do not assume the same transaction terms or service scope applies to both.

2. Atradius Collections — international B2B agency route

Atradius Collections publicly describes domestic and international B2B collection, amicable outreach, an online case portal, and a global lawyer network for legal work when needed. That makes it a useful first agency quote when a debtor sits outside the creditor's country or a company has cases in several markets. Its offering is collection for a client, not an automatic outright purchase of the receivable.

Ask Atradius to confirm it can handle your exact debtor country, whether the case is managed by its own local team or a partner, what language will be used, whether a disputed invoice is accepted, and who approves legal escalation. Get a stage-by-stage price for amicable collection and any legal step, plus an explanation of remittance currency, reporting, and what happens if no payment is collected. Its international materials are first-party descriptions, not an independently verified outcome for your claim.

3. Intrum — coordinated collection for a multi-country book

Intrum's international-collection service describes local teams in European markets and a partner network for additional countries. Its multinational collections hub emphasizes one account-management and reporting structure across markets. That model may help a finance team with many debtors and a need to manage placements consistently.

Confirm coverage per country and per claim type, especially for a heavily disputed invoice or a market served through a partner. Ask what remains in-house, when local counsel is engaged, what information the seller can see, how settlements are approved, and how fees change on legal referral. A network can reduce coordination work, but it does not make local rules, time limits, or recovery outcomes uniform.

4. Bierens — European B2B collection with a legal focus

Bierens presents itself as a European business-debt collection law firm with local-language specialists, collection attorneys, and case tracking. It is most relevant when the debtor is in a European market and payment turns on a contract dispute, legal demand, or local procedural question. The firm's published descriptions and results are its own claims; ask for a written assessment of the specific claim rather than treating a marketing success rate as a forecast.

Have Bierens identify the responsible professional and jurisdiction, the pre-legal and court phases, costs and disbursements, document-translation requirements, and whether it will represent you directly or use a local partner. That is especially important when the creditor is in the U.S. and the debtor's country will control the practical collection steps.

5. Local counsel — when the claim cannot be reduced to a standard workflow

For a large single claim, insolvency, a contested contract, a choice-of-law or forum issue, or a question about enforcing an existing judgment abroad, a lawyer qualified in the relevant jurisdiction may be the clearest first call. Counsel can assess the actual contract and local process, decide what proof is needed, and quote a strategy before the creditor commits to a demand, suit, or settlement. The right jurisdiction may depend on the contract, debtor, assets, and applicable law; an article cannot decide it from the country names alone.

If an agency offers legal escalation, ask which lawyer would handle it and what consent and additional budget are required. If a U.S. judgment already exists, do not assume it can be collected directly against foreign assets without local advice. Conversely, a foreign creditor chasing a U.S. debtor should get U.S.-qualified advice about the applicable state and any existing foreign judgment.

A decision framework for a real invoice

If the debtor is in the U.S. and the seller is a U.S. business: Ask whether an eligible overdue commercial claim can be sold to Delos, and compare the written sale proceeds with a domestic agency or legal route. A claim arising from international trade is not automatically a foreign-enforcement case if the debtor and its reachable assets are in the U.S.

If the debtor is outside the U.S.: Start with an agency or lawyer whose actual service covers that country and claim type. Ask Atradius, Intrum, Bierens where relevant, or country-qualified counsel for a quote. Treat Delos as an inquiry only if it separately confirms eligibility; do not list it as the provider of foreign legal enforcement.

If the portfolio spans both: Make a debtor-country and status schedule, then assign different segments to the right route. Include invoice amount and currency, contract/forum clause, debtor identity and assets, delivery proof, dispute status, age, previous collections, and any judgment. Delos's enterprise team can discuss the U.S.-claim purchase or servicing portion; an international collector can quote the foreign-country portion. Neither lane should silently claim the whole global book.

If a customer will negotiate directly: A documented payment plan may preserve the relationship and more of the face amount, but only if payments arrive. Compare its realistic net value and timing with agency fees, counsel costs, and any actual purchase proposal. If evidence or solvency is weak, consider a documented write-off decision with accounting and legal advisers rather than assuming any service guarantees collection.

Questions to ask every provider

1. Can you handle this specific debtor country and the law or forum named in the contract? Is the case managed by your staff, a partner agency, or named local counsel?
2. Do you accept this claim type and size, including any dispute, offset, insolvency, judgment, or assignment restriction?
3. Who owns the claim during the work? Is this a purchase, a collection placement, or legal representation?
4. What are the net proceeds or total costs under a realistic scenario: price or advance, agency fee, legal fees, disbursements, translation, currency conversion, and remittance timing?
5. Who controls settlements and legal escalation? What reporting, exit rights, exclusivity, and documentation requirements apply?

Written answers beat broad promises about country counts, 24-hour action, success rates, or low fees. If a deadline or legal right may be close, consult relevant counsel promptly while you compare commercial options.

FAQs

Does Delos buy an invoice owed by a customer abroad?

Do not assume so from a cross-border article. Delos's main public route is case-by-case purchase review of an eligible overdue business claim. This guide positions it as a strong candidate for a qualifying U.S.-debtor claim; a foreign debtor or foreign seller requires explicit eligibility confirmation. For collection or litigation in the debtor's country, compare a provider with verified local capability or qualified local counsel.

Can a foreign business sell a claim against a U.S. debtor to Delos?

It can ask, but the creditor's location, debtor, contract, rights being assigned, and applicable jurisdiction require review. The public materials do not establish a blanket rule that every foreign seller or every U.S. state is eligible. Seek a written answer for the specific invoice before treating a sale as available.

Which provider is best for a European debtor?

For several European markets, compare Atradius Collections and Intrum on actual country coverage, case management, fees, and legal referral. For a contested European B2B invoice, Bierens or a lawyer in the relevant country may be more appropriate. There is no honest universal winner without the debtor country, contract, amount, and dispute details.

Do I need a lawyer in every debtor country?

Not necessarily for amicable collection: an international agency may coordinate local-language outreach and refer legal work if needed. But if court proceedings, judgment recognition, or enforcement are required, ask who will provide legally qualified representation in that jurisdiction and what it will cost. Do not infer that software alone can practice law abroad.

Is selling the receivable better than cross-border collection?

A completed sale can give a seller defined proceeds without waiting for eventual collection, but a buyer may discount or decline a hard-to-prove foreign claim. Collection preserves ownership and potential upside while leaving timing and outcome uncertain. Compare an actual written purchase proposal, if one exists, with agency and counsel estimates; do not assume Delos or another buyer will purchase every foreign-debtor invoice.

Bottom line

The best cross-border recovery route follows the debtor and the contract, not a generic software ranking. For a qualifying overdue claim against a U.S. business, ask Delos about direct purchase and compare the agreed sale economics with continued collection. For a debtor abroad, request country-specific proposals from an international B2B collector or local counsel. Keep U.S.-claim purchase and foreign-country collection separate, especially when one portfolio contains both.
