"The money is in the system" is the only sentence in finance that is almost always true and almost never useful. Everything is in some system. The question is whether it's in a bank's.
The uncomfortable part: most creditors who hear that sentence can't say which bank should be holding the money at that moment, or what would prove it. Neither can most debtors. That is exactly why the sentence works.
In the System: a one-minute case file
Read the story
Rio de Janeiro. Tadeu Barreto sells more Norwegian salt cod than anyone in Brazil. He owes $98,000 for forty tonnes of it, and he has one sentence for his supplier: the money is in the system.
Kari Lunde, sales director at Lunde Sjømat in Ålesund, hears it on day 3. On day 9 she receives an 'MT103' payment confirmation with no tracking reference. On day 16 the payment is 'held by a bank in New York for compliance'. When her father asks where their money is right now, she tries to draw its route on a whiteboard, and can't.
Her brother Magnus offers to sail to Rio and take the cod back. It has been eaten. So Kari calls Luana Ribeiro, a local collector in Rio de Janeiro who spent twelve years in bank payment operations.
Luana asks Tadeu one question: the UETR, the 36-character reference every cross-border SWIFT payment carries. His confirmation has none, and it uses three fonts. Kari's bank searches November's incoming dollar payments: nothing from Brazil, nothing held in New York. The payment was never sent. Luana sets out the next step: an ação monitória in Rio, with fifteen days to pay once served.
Tadeu sends the payment properly. The tracker shows it leaving Rio, passing through New York and landing in Ålesund. Day 6: $98,000, paid in full. In December, Tadeu doubles his Christmas order. UETR first.
Lesson: a screenshot can be faked. A tracking number can't.

Draw it before you chase it
Take the last international payment you received and sketch its route: which bank sent it, which banks it passed through, which one credited you, and what reference connected them. If your sketch reads "their bank, then something, then our bank", you're in good company. It's also the gap every "it's in the system" excuse lives in.
There are really only two routes
For euro payments inside the SEPA area (the EU, plus countries such as Norway, Switzerland and the UK), a standard SEPA credit transfer must reach the payee's bank by the next business day. Instant transfers arrive in seconds, and since October 2025 banks in the euro area have had to check the payee's name against the IBAN before the payer confirms. A euro payment from inside SEPA that has been "in the system" for a week is not in the system.
Everything else (dollars, most cross-currency payments, anything moving in or out of SEPA in another currency) travels over SWIFT, often through one or more intermediary banks. That route can genuinely take a few days and can genuinely stop for a compliance check. Which is why it comes with a tracking number.
The 36-character answer
Every cross-border SWIFT payment carries a UETR, a unique end-to-end transaction reference: 36 characters in five groups, such as 8a562c67-ca16-48ba-b074-65581be6f001. It is created when the payment is sent and travels with it through every bank on the route. Banks on SWIFT's tracking service can see where it is, and whether it was credited, returned or is waiting.
So when a customer says the payment is on its way, the useful reply isn't "please confirm". It's "could you send us the UETR and the value date?" A customer whose bank actually sent the money can get that in minutes. A customer whose payment exists mainly as a PDF will need longer.
For SEPA transfers, ask for the execution date and the end-to-end reference instead.
What a fake "MT103" usually looks like
People still call a payment confirmation an "MT103", even though SWIFT moved cross-border payments to the newer ISO 20022 message format in November 2025. The name isn't the giveaway. These are: no UETR anywhere on the document, a value date that doesn't fit the story, beneficiary details typed slightly differently from your invoice, and more than one font. Real bank confirmations are dull, generated documents. Fakes tend to try harder.
Then take the reference to your own bank, which can search incoming payments for it. If nothing matches, you have your answer, and so does your customer, even if they haven't told you yet.
When "the intermediary bank is holding it" is true
Sometimes it is. Payments do get held for compliance checks, particularly in dollars and particularly between unusual counterparties. A real hold still has a UETR, and the paying bank can see its status. "It's being held" with a reference is a delay. "It's being held" without one is a story.
What to do this week
Add one line to your payment reminders: "please include the UETR (SWIFT) or the end-to-end reference (SEPA) with your remittance advice." It costs nothing. Customers who genuinely paid will send it without thinking. The ones who didn't will tell you something by taking a long time.
If a customer's payment has been "in the system" for longer than the system takes, Collecty's local collectors can check it with you and take the next step in the customer's own country. Start here.
