Figures published on September 4, 2026, show 2,849 Article 17 Wwft requests for additional information in 2025. An unusual-transaction report can prompt questions at several regulated firms. Payment, customer, contract, and invoice records affect how quickly those questions can be answered.
Why this matters
An unusual-transaction report can lead to a wider review of the file. Article 17 permits requests to the reporting firm and another Wwft-obliged firm with relevant records. Both must respond without delay. Banks, accountants, tax advisers, notaries, and payment providers may ask customers for invoices, contracts, account statements, or correspondence. Trouble starts when the invoice, payment, and ledger describe different deals. Staff then rebuild an old transaction from emails and scattered files.
Example
A related company pays a customer invoice to cover a short-term cash problem. Everyone involved understands the arrangement. Months later, the bank asks why the payer differs from the customer. An accountant must show how the invoice was cleared. One employee holds the explanation in an email outside the customer file. The bank reference says little. The payment may be commercially valid. A short note, clear authority, and matching ledger entry would connect the payer, customer, invoice, and debt settlement.
XTROVERSO tips
- Find third-party payments. Review invoices paid by someone other than the named customer. Record who paid, on whose behalf, and why.
- Match the core records. Compare the contract, invoice, bank reference, delivery evidence, and ledger entry. Each should describe the same transaction.
- Document related-party flows. Keep agreements for shareholder loans, management charges, and payments between related companies. Record the amount, purpose, authority, and accounting treatment.
- Use useful invoice descriptions. State what was supplied. Avoid labels such as “services” or “consultancy” when they do not explain the work.
- Test file retrieval. Check whether staff can find the customer record, contract, invoice, correspondence, and payment evidence without searching personal inboxes.
- Keep Wwft client files current. For Wwft-obliged firms, update the client file when ownership, directors, signatories, risk details, or the relationship purpose changes.
