Having the request in writing creates a paper trail for both parties' accounting records.\n",{"question":388,"answer":389},"How do I prove a duplicate payment was made?","The strongest evidence is a bank statement or payment portal screenshot showing two identical debits on or near the same date, combined with the payment confirmation or remittance advice for each transaction. Include the original invoice as well so the vendor can match all three documents — the invoice and both payments — without needing to contact you.\n",{"question":391,"answer":392},"How long should I give the vendor to process a refund?","Ten to fifteen business days is the standard request window for a straightforward duplicate payment refund. Larger vendors with formal AP processes may need up to 30 days to route and approve the refund internally. Set a firm date in your letter and request written acknowledgment within five business days so you know the letter reached the right person.\n",{"question":394,"answer":395},"Should I request a cash refund or a credit memo?","A cash refund — by ACH or check — is preferable when you need to restore your working capital or when the vendor relationship may end. A credit memo is faster to process on the vendor's side and works well for ongoing relationships where the credit will be applied against the next invoice. State your preference clearly in the letter; vendors default to whichever option is easiest for them otherwise.\n",{"question":397,"answer":398},"Can I send this letter by email, or does it need to be mailed?","Email is appropriate for most duplicate payment refund requests and produces a timestamped delivery record. Use certified mail or courier for amounts above $5,000, for vendors you have had difficulty reaching, or when the situation may escalate to a formal dispute or legal claim. In either case, attach the supporting documents rather than promising to send them separately.\n",{"question":400,"answer":401},"What if the vendor ignores my refund request?","Send a follow-up after the deadline passes, referencing the original letter by date and the outstanding amount. If a second request goes unanswered, escalate to a formal demand letter from your company's legal department or counsel, or initiate a chargeback through your bank if the payment was made by credit card or an eligible ACH method. Keeping dated copies of all correspondence is essential at this stage.\n",{"question":403,"answer":404},"Does a duplicate payment refund request letter need to be signed?","A formal signature is not legally required for a refund request letter to be valid, but including the name and title of an authorized signatory — accounts payable manager, CFO, or business owner — adds credibility and signals that the request has internal approval. Most vendors process signed letters faster than unsigned ones because they can verify authority without a callback.\n",{"question":406,"answer":407},"What information must I include in the letter?","At minimum: both parties' contact details, the invoice number, the reference numbers and dates of both payments, the exact refund amount and currency, the preferred refund method with banking details, a response deadline, and a list of attached supporting documents. Missing any of these will slow the vendor's verification process and delay the refund.\n",[409,413,417,421],{"industry":410,"icon_asset_id":411,"specifics":412},"Professional Services","industry-professional-services","Law firms, accounting practices, and consultancies frequently pay vendor invoices through multiple systems — billing software and a bank portal — creating duplicate ACH payments that require formal recovery letters.",{"industry":414,"icon_asset_id":415,"specifics":416},"Retail and E-commerce","industry-retail","High transaction volumes and automated payment runs increase the risk of duplicate supplier payments during peak seasons, making a standardized letter template essential for the AP team.",{"industry":418,"icon_asset_id":419,"specifics":420},"Construction and Trades","industry-construction","Progress billing and milestone payments to subcontractors are processed in batches, and duplicate payments commonly occur when paper checks and electronic transfers are used in parallel.",{"industry":422,"icon_asset_id":423,"specifics":424},"Healthcare","industry-healthtech","Medical practices and hospitals pay suppliers, labs, and equipment vendors through complex billing systems where duplicate payments arise from insurance reimbursements processed alongside direct payments.",[426,430,433,437],{"vs":427,"vs_template_id":428,"summary":429},"Demand letter","D{DEMAND_LETTER_ID}","A demand letter is an escalation tool used after informal requests have failed — it typically carries legal weight and may precede litigation.

It identifies both transactions by reference number and date, states the exact amount being claimed, attaches supporting bank evidence, and specifies how and by when the refund should be returned. The letter functions simultaneously as a recovery instrument and an auditable accounting record — giving both parties a clear paper trail for reconciliation, period-end close, and dispute resolution if the refund is not processed promptly.\u003C/p>\n\u003Ch2>Why You Need This Document\u003C/h2>\n\u003Cp>Without a written refund request, a duplicate payment is easily overlooked on the vendor's side — the extra funds are absorbed into their receivables, credited against a future invoice you didn't agree to, or simply not noticed until your next statement reconciliation. Verbal requests have no paper trail and give you nothing to escalate with if the vendor disputes the claim or stops responding. A properly drafted letter with transaction references and attached bank evidence compels faster action, satisfies your own accounts-payable audit requirements, and establishes the documented notice date you need if the matter escalates to a formal demand or bank chargeback. For finance teams, it also closes the control gap that allowed the duplicate payment in the first place — creating a record that the error was caught, reported, and resolved. This template gives you a professional, complete letter in under 15 minutes.\u003C/p>\n",1780924333592]
