# Detect tampered and deepfake Remittance Advice > A remittance advice tells a supplier which invoices a payment covers. Accounts receivable teams use it to allocate cash, and fraudsters use fake ones to pressure a supplier into releasing goods before any money has arrived. Because the document is a simple list of invoices, dates, and amounts that must sum to a payment total, and because the payment should exist at the bank, a false one fails checks quickly. **Canonical URL:** https://tampercheck.ai/documents-support/remittance_advice **API document class:** `remittance_advice` --- ## What a genuine remittance advice contains A remittance advice names the payer and payee, the payment date, the method, and a payment reference. It lists each invoice settled with its number, date, and amount, shows any discounts or deductions such as credit notes, and states the total remitted. The payer's bank details may appear, and some systems include the payee's account to which the funds were sent. The total equals the sum of the invoice lines less deductions, and every invoice listed should exist in the supplier's ledger with a matching amount. The payment reference should be found on the supplier's bank statement. Genuine advices come from the payer's finance system, so their layout, sender address, and reference format stay stable from one payment to the next. ## How remittance advice forgeries are made ### Payment that never happened An advice is produced for a transfer that was not made, to obtain goods on credit. It cannot be matched to a bank credit, and its layout departs from the payer's earlier remittances. ### Inflated payment total The amount is raised, or invoices are added, so the payer appears to have cleared more debt. The lines stop summing to the total, and the edited numbers have distinct rendering. ### Bank detail substitution The payee account shown is changed to hide where the funds actually went, or to set up a later redirection scam. The edited lines stand out against the system-generated text. ### Invoice number edits References are changed so a payment is allocated to a different invoice. The invoice date and amount no longer match the supplier's ledger. ## What TamperCheck checks on a remittance advice TamperCheck runs 200+ forensic checks across three layers and returns a risk score from 0 to 100 with plain-English findings tied to specific regions of the document. These three carry the most weight on this document class. ### Arithmetic reconciliation Stated totals are recomputed from their components, and running or cumulative figures are checked for continuity across periods. A single edited value breaks the chain even when the page still looks right. ### Table structure integrity Inserted and deleted rows leave structural artifacts behind: inconsistent spacing, misaligned columns, and formatting the visible table no longer accounts for. ### Date and validity consistency Issue, expiry, and period dates are checked against one another and against the file's own creation metadata, which catches backdating and validity extension. ### And many more checks The three above are the layers that carry the most weight on a remittance advice. Every upload runs the full suite of 200+ checks regardless of document class, spanning file structure and metadata, pixel-level forensics, font and text rendering, optical and print characteristics, provenance signals, AI-generation signatures, and many more checks. ## Who verifies a remittance advice, and why Accounts receivable teams, suppliers, and credit controllers. In each case the document is being used to unlock money, access, or a legal status, which is exactly what makes it worth forging. ## How to verify a remittance advice in 4 steps 1. **Check the fields against each other.** Read payment total, invoice list, and payment reference together rather than one at a time. Forgers typically change one value and leave the rest of the document describing the original. 2. **Inspect the file metadata.** Open the document properties and look at the producer, creation date, and modification date. A document produced by a consumer PDF editor, or created long after the date printed on its face, is worth a closer look. 3. **Ask for a second document.** Request a corroborating document from the same issuer or an adjacent period. Forgery effort concentrates on one file, so inconsistencies surface as soon as there are two to compare. 4. **Run a forensic check.** Manual review catches obvious edits but not field-level pixel manipulation or synthetic generation. TamperCheck runs 200+ forensic checks on a remittance advice and returns a risk score from 0 to 100 in about a minute, at $0.50 per document. ## Frequently asked questions ### How do suppliers detect a fake remittance advice? By matching it to the bank. A real payment appears as a credit with the same reference and amount. Beyond that, they check that the invoices exist and add up, and compare the advice's format with the payer's earlier ones. ### What is edited on a payment advice? The total, the list of invoices, the payment date, and the bank details. Each affects how the supplier allocates cash or where it later sends refunds, so they are the fields worth testing. ### Is a remittance advice proof of payment? No. It is the payer's notice that a payment was made or will be. Proof is the credit on the supplier's bank statement. Treating an advice as proof is precisely the gap that fake ones exploit. ### How is a remittance advice different from a receipt? A remittance advice comes from the payer and lists what a payment covers. A receipt comes from the payee and acknowledges that funds were received. The direction of the document is the easiest way to tell them apart. ## Related document types - Invoice: https://tampercheck.ai/documents-support/invoice - Receipt: https://tampercheck.ai/documents-support/receipt - Purchase Order: https://tampercheck.ai/documents-support/purchase_order - Cheque: https://tampercheck.ai/documents-support/cheque - Wire Transfer: https://tampercheck.ai/documents-support/wire_transfer - Payment Schedule: https://tampercheck.ai/documents-support/payment_schedule --- Try TamperCheck now: https://tampercheck.ai/dashboard · Docs: https://tampercheck.ai/docs · Pricing: https://tampercheck.ai/pricing
