How to Accept ACH Payments on Your Website
Learn how to accept ACH payments on your website, including ACH Debit and Credit, bank verification, mandates, settlement, disputes and refunds.
Clear policies, recognisable billing, reliable fulfilment and carefully calibrated fraud checks are the key ingredients when it comes to chargeback prevention. Master these areas and you've got a recipe for reducing avoidable disputes without making genuine customers work harder to buy.
This guide touches on all four of these aspects of chargeback prevention and explains the main types of chargeback, practical ways to prevent them, the evidence to keep, and the payment-method decisions that can reduce dispute exposure for higher-value transactions.

A chargeback happens when a cardholder questions a payment with their card issuer. The issuer can raise a dispute through the card network, and the payment may be reversed while the case is reviewed. This can remove the transaction value and add a dispute fee or administrative cost.1
Chargebacks can arise from:
The main categories are merchant error, true fraud and friendly fraud. Merchant error includes duplicate charges, incorrect amounts, failed refunds and charges made after cancellation. True fraud involves an unauthorised transaction. Friendly fraud occurs when a genuine customer disputes a legitimate payment because they forgot the purchase, misunderstood a subscription or couldn't get support.
A chargeback can cost more than the original sale. The business may also lose the product, delivery cost, dispute fee, staff time and future processing capacity.
Put refund, return and cancellation terms near checkout and link to them from order confirmations and account areas. Use plain language and state:
Retain the version of the terms accepted at checkout where appropriate.
Send a receipt that identifies the business, order, amount and products purchased. If an item is delayed or unavailable, tell the customer promptly and explain the options.
For physical goods, provide tracking when available. Avoid promising a delivery date that your warehouse or carrier can't reliably meet. A customer who understands when an order will arrive has clearer grounds to contact the business before a delivery problem becomes a dispute.
Record changes to delivery dates, customer notifications, replacement orders and cancellations. These records can support a response if a customer later claims that goods or services weren't received.
Make support details easy to find on the website, receipts, delivery emails and account pages. Give the team a clear process for handling:
Fast, clear support can resolve a problem before the customer contacts their bank. The fraud-prevention guidance also recommends making contact information easy to find, keeping customers updated and processing refunds or replacement orders quickly.2 Record the customer's message, the response, any agreed action and when it was completed.
Support should also be able to identify a payment quickly. Ask for an order number or other reference, then confirm the amount, product, delivery status and available resolution.
The descriptor on a customer's statement should connect the payment to your business or trading name. If the legal entity and customer-facing brand differ, choose wording that customers are likely to recognise.
A recognisable descriptor can prevent a legitimate payment from being mistaken for fraud. The fraud-prevention guidance recommends using a statement descriptor that customers can recognise.2 Include the order reference or other customer-facing identifier where the payment setup allows it, and make sure receipts use the same business identity.
Review the descriptor after launch by checking how it appears on real statements. A descriptor that looks unfamiliar can create customer queries and avoidable disputes even when the underlying payment is legitimate.
For goods dispatched later, consider whether capturing the payment before shipment could create confusion or a non-delivery dispute. Follow the rules and capabilities of your payment provider, and keep the capture, dispatch and delivery timestamps together.
Avoid submitting payments so early that the customer sees a charge long before the order is ready. Avoid delays that create a separate late-presentment risk.
Build checks for common merchant errors:
Reconcile payments, refunds and cancellations regularly. A chargeback caused by a preventable processing error can usually be addressed more effectively by fixing the workflow that created it.
💡 If you accept card payments through Wise Business, our chargeback guidance explains how to accept or dispute a chargeback and the evidence you may need to provide.
Keeping proof of delivery, proof of service, business terms and customer communications can help you prepare a focused response when a dispute occurs.
Use the risk information available in your checkout and payment stack. Review orders when signals include:
Depending on your payment setup, checks may include address verification, card-security checks, device and IP signals, velocity rules, strong customer authentication and manual review.
According to Shopify's fraud analysis guidance, its analysis can help merchants identify potentially fraudulent orders. The guidance also warns that fulfilling high-risk orders can contribute to chargebacks and may affect payment-processing access.5
Automated fraud tools can evaluate multiple transaction signals and apply rules to help identify high-risk payments before fulfilment.3
Use risk analysis as a decision aid. A high-risk flag should lead to a proportionate review rather than an automatic rejection in every case. Review false declines alongside fraud losses so the controls don't create unnecessary friction for genuine customers.
For each physical order, retain:
For digital goods and services, keep access logs, download records, account activity, accepted terms and relevant support messages.
Organise evidence so it can be retrieved by order number, payment reference or customer account. Evidence that is technically available but difficult to find can delay a response and weaken the explanation of what happened.
Subscriptions need clear customer communication. Show the trial end date, renewal frequency, renewal amount and cancellation route before the customer starts paying.
Useful controls include:
Don't keep charging after a valid cancellation request. Record the request, effective date and resulting payment action.
If a customer disputes a recurring payment, retain the subscription terms, trial and renewal dates, acceptance record, reminder messages, payment receipts, cancellation history and relevant account activity.
Cards and wallets can make consumer checkout quick and familiar. For a high-value B2B invoice, a bank transfer may give the parties a clearer settlement record and reduce exposure to card-specific chargebacks.
The choice still depends on the customer's expectations, refund process, payment confirmation and reconciliation needs. Define when the payment is considered received and how refunds will be handled.
For eligible B2B customers, Wise Business can support payment collection through local account details. It can be a useful option around invoices where the customer and business agree that bank transfer is appropriate.
If you're accepting payments from US bank accounts, ACH Direct Debit guidance describes a delayed payment method that can take up to four business days to receive acknowledgement of success or failure and carries a risk of failed payments and disputes.4 Check the payment method's current terms and timing before relying on it for a fixed settlement date.
When a chargeback happens, start by identifying the reason and response deadline. Then:
For an unauthorised-payment claim, evidence may include authentication results, address and card-security checks, device and IP information, account history, previous successful payments, customer communications, delivery evidence and accepted terms.
For a non-delivery claim, keep the product and order description, dispatch timestamp, carrier and tracking information, delivery address, delivery confirmation and customer updates about delays.
For a cancellation or refund claim, keep the cancellation request, date and channel used, applicable terms, refund record, date and amount refunded, and any message explaining the refund timing.
A focused response that addresses the reason for the chargeback is more useful than a generic document bundle. If the customer has a legitimate complaint and a refund is still possible, resolve it through your normal process and record the refund clearly.
Assign ownership across fraud, payments, customer support, fulfilment and finance. Review chargebacks by:
A monthly review should also ask:
Segment your controls. A repeat customer with a clean history can be assessed differently from a first-time customer placing a high-value order with unusual delivery details.
Avoid common mistakes such as treating every dispute as stolen-card fraud, hiding refund terms, making support difficult to contact, fulfilling high-risk orders without review, sending generic evidence or measuring only chargeback wins.
Test changes against both dispute performance and conversion. A lower chargeback rate accompanied by a large increase in false declines may represent a poor customer outcome.
