Distance weakens chat. A portable record travels.

An unpaid invoice is hard enough in the same town. Across a border it picks up extra fog: different currencies, slow transfers, time zones that turn every exchange into a day, and the quiet feeling that you are too far away to chase. You cannot remove the distance. You can remove the fog, by making the whole debt one portable record anyone can check, and the payment itself easy to send correctly the first time.

Updated October 24, 2026. The two delivery records quoted below are real and public, with their client decision states read back from the live service on publication day.

Step 1. Build the portable evidence base first

Before you write another chase message, assemble the record the whole effort will stand on: the agreement, the delivery, the acceptance with its date, and the invoice, behind one link that opens without an account. The record format is AER-1, published as an IETF Internet-Draft (draft-zambo-aer1-26), and each step carries a verifiable receipt: a receipt proves the saved result was not changed since it was saved. The two public records below show the pattern. An accepted record, decided_by client with its date and release_hint ok_to_release, can be read and judged by anyone in any country. That portability is the point: your evidence should not depend on your laptop, your chat history, or you being awake in their time zone.

Step 2. Restate the invoice so it can be paid without questions

Send one clean restatement with the demand: the amount, the currency in words as agreed, the due date now passed, the invoice reference, your complete payment details in one block, and the exact reference the client must include. Cross border delays are frequently clerical, not hostile: a payment sent in the wrong currency, a reference left off, a fee taken out of the amount so it lands short and nobody can match it. Close those doors in advance. If transfer costs were never agreed, say how a short landing will be handled before the client sends. When any payment arrives, confirm it in writing the same day with the remaining balance, so the money record stays as clean as the delivery record.

Accepted: the decision is on the record

Pending: checked, and still waiting on a decision

For cross border work the acceptance state matters twice over, because there is no easy meeting where it can be sorted out in person. Get the record to accepted, or get the client silence about a pending record answered in writing, before the demand goes out.

Step 3. Send one formal demand with the packet link

The demand itself should be short enough to forward and complete enough to judge alone: the work, the delivery and acceptance dates, the invoice and balance, the packet link, and one pay by date stated with its time zone. Offer the three offramps in the same message: pay in full, agree a written payment plan by that date, or name the specific item disputed by that date so it can be answered on the record. A demand that can be forwarded unchanged to the client accountant or adviser is far stronger than a long emotional thread, because the person who releases payment is often not the person you have been chasing.

Step 4. Work the offramps before you escalate

Most cross border balances that get paid, get paid through an offramp, not through pressure. A payment plan works the same across borders as at home: written amounts and dates, the first part paid on agreement, every part confirmed against the same invoice. A genuine dispute gets answered from the record, line by line. Even a settlement, a reduced amount accepted as full payment, can be the right economics once transfer costs and months of chasing are priced honestly, and it should be confirmed in writing as settling this invoice in full before money moves. Escalation stays available the whole time. It just stops being the only door.

Step 5. Escalate with the packet, and price it honestly

If the pay by date passes, the options are general ones and they vary by country: mediation, a collections service that works in the client country, or local legal advice there or at home. This page is general information, not legal advice, and cross border rules are exactly the kind that differ by place. Judge any route by the balance against its cost, its time, and the chance of collecting at the end of it, and take the packet with you: a complete, portable record is what makes a mediator or a collections service able to take the case seriously at all. Send one written notice naming the step you are taking and its date, then take it. Deadlines that move teach the client that distance worked.

Step 6. Set the next international job up differently

The lessons price into the next agreement in four lines: the currency named in words, a deposit before work starts, stages delivered and accepted on the record with each stage paid before the next begins, and final files after the final payment clears. None of that signals distrust. It signals that you work internationally as a routine, which experienced international clients recognise and respect. The portable record does the quiet work underneath all of it: if a future balance is ever questioned, the delivery and acceptance are already in the one form that travels, checkable from either country without your help.

What a record does not settle

A verifiable receipt proves the saved result was not changed since it was saved; it does not prove a foreign court or service will act on it, does not fix a wrong currency or a missing payment reference, and cannot move money a client refuses to send. This page is general information, not legal advice. Rules and collection routes vary by country: check yours, and get local advice for a large balance.

Frequently asked questions

How do I collect payment from a client in another country who has not paid?

Start by making your evidence portable, then ask for payment in a way that is easy to check and easy to pay from anywhere. Put the delivery and acceptance record behind one link the client, or anyone helping either of you, can open without an account and without your narration: what was delivered, when, and the acceptance with its date. Restate the invoice cleanly in one message: the amount, the currency it was agreed in, the due date, the invoice reference, and exactly how to pay, with the payment reference to use. Send one formal written demand with that packet link and a pay by date. Offer the clear offramps: pay in full, agree a written payment plan, or name the specific line disputed by that date. Distance makes scattered chat evidence weak and slow. A single checkable record travels across borders at full strength, because anyone, anywhere, can open it and see the same delivery.

Does being in another country change what counts as proof of delivery?

The proof needed is the same: agreement, delivery, acceptance, invoice. What changes is how hard scattered proof is to use. Screenshots of chat in another language, files in threads nobody can find, and an acceptance given on a call are awkward at home and close to useless across borders, where nobody can easily meet, call, or check your systems. A portable record answers that: one link, the steps and saved results in order, the client decision with its date, readable by the client, a mediator, a collections service, or an adviser in either country without needing access to your accounts. Build the proof as if a stranger in another time zone will judge it, because that is the realistic reader.

How do I make an international invoice easy to pay?

Remove every small friction, because each one becomes a reason to delay. State the currency in words on the invoice, not only a symbol, and keep it the currency the price was agreed in. Show the exact amount, the due date, your full payment details in one block, and one reference the client must include so the payment can be matched to the invoice. Say who covers transfer costs if that was agreed, and if it was not agreed, raise it before the client sends, not after a short payment lands. Confirm receipt in writing the day any payment arrives, with the remaining balance restated. Cross border payment problems are often boring problems: a missing reference, a wrong currency, a fee quietly taken from the amount. A clean invoice prevents all three.

What if a client in another country simply goes quiet?

Shorten the distance with rhythm and a record, not with volume. Send the formal demand with the packet link, then short reminders on stated dates, each restating the balance, the due date, and the record link, in the same thread. Name the next step and its date plainly: a mediation service, a collections service, or local advice in the client country, and follow through or formally extend once in writing. Keep every message factual and complete enough to forward, because the person who eventually reads it may be an adviser who has never heard of either of you. Silence across borders is often avoidance, and avoidance usually survives on the debt feeling vague. A dated record and a dated demand make it specific, which is what gets quiet clients to answer.

Why does a portable record matter more for international work?

Because you cannot walk the proof over. A client checkable record is the evidence base that works at a distance: the delivery, the acceptance, and the invoice story in one place, openable from any country, in any time zone, without your accounts or your presence.
