One invoice.
Two payments?
Match the invoice and both payments before requesting a duplicate-payment refund. Give the vendor a clear record and specify how you want the overpayment resolved.
Connect Gmail to get started. You approve each money action.
Confirm that two completed payments cover the same invoice, then send the vendor the invoice number, payment dates, amounts and references. Ask for a refund or an agreed account credit, and keep the item open until the money or credit appears.

Make sure it is the same obligation.
Compare vendor, account, invoice number, currency and amount. Check the service period and any partial-payment arrangement. Two charges with the same amount may pay for different invoices.
Verify each payment through your normal payment records. A pending item can be different from a completed payment. If one item has already reversed, update the record before sending a refund request.
Give billing a request they can reconcile.
Attach or reference the invoice and payment confirmations. Use payment references that identify the transactions without sending full bank or card credentials. State whether you want the excess returned or are willing to accept a credit.
Ask for the vendor’s reconciliation and a case number. If the vendor cannot find one payment, ask which reference or payer detail is missing. Keep the conversation in one thread to avoid parallel refund and credit requests.
We appear to have paid invoice [number] for [amount] twice: [date/reference] and [date/reference]. Please reconcile both payments and refund the duplicate [amount] to the original payment method. If you propose an account credit instead, please confirm the details before applying it.
A credit and a refund have different uses.
A refund returns money. A credit may reduce a later bill. Before accepting a credit, confirm that the business expects to buy from the vendor again, how the credit is identified and which invoice should use it.
If the vendor reports a refund, ask for its amount, date and reference. Check the business’s own records for the result. Do not record both a refund and an applied credit as recovered money for the same overpayment.
Fix the path that allowed two payments.
After resolving the duplicate, check how the invoice entered the payment process. It may have arrived twice, used different supplier names or been paid by two people. Keep the invoice number and vendor account consistent in your records.
Give one owner responsibility for the open request. Update the tracker and bookkeeping records when the outcome is confirmed, using your existing reconciliation process.
We find the money.
We do the chasing.
Huck finds the money slipping out of your business, shows you what each charge is worth, and does the chasing when you say so. Cancellations, refund requests and vendor negotiations follow through to a result you can check.
Connect Gmail. No bank login. Anything that moves money always asks.
See how Huck handles bills and renewals ↗We find the charge.
Huck finds renewals, price increases, duplicate payments and refunds owed in your Gmail, with a dollar figure on each finding.
You decide.
Review the proposed change. Cancellations, downgrades and refund requests need your yes each time.
We do the chasing.
Huck cancels, requests the refund or works the vendor’s chat, then follows up until the request is settled. Huck checks your bill for the lower charge, credit or refund and texts you the result.
A few things
before you act.
Does the same amount twice prove a duplicate?
No. Match invoice numbers, accounts, service periods and completed payment records first.
Should I accept an account credit?
Check whether it can be used and whether it fits the business’s needs. Ask for the amount and application details in writing.
What can Huck find?
Huck’s confirmed scope includes finding vendor invoices paid twice in email and requesting an approved refund or credit. It does not need your bank login.
