What is the WAVE charge on my credit card?

What this charge usually means

A charge labeled WAVE on your credit card statement is commonly tied to a payment processed through Wave, a small-business invoicing and accounting platform. Many freelancers, contractors, and small companies use Wave to send invoices and accept card payments. Because the payment is routed through Wave, the descriptor can show as WAVE instead of the exact business name you expected.

In most cases, this is a legitimate card payment for a service, project, consultation, subscription installment, or invoice you approved. It is often a one-time payment, but recurring charges can happen if you agreed to repeated billing with the merchant who invoiced you.

Why it appeared

• You paid an invoice from a business that uses Wave payments.
• A family member or team member used your card for a business expense.
• A delayed capture posted days after the invoice was paid.
• A recurring agreement was set up with the seller, even if the descriptor only shows WAVE.
• The merchant name on the invoice differs from the legal or processing name shown on statements.

If you are comparing this to other generic descriptors, you may notice similar confusion patterns with platforms like Patreon or wallet-style processors like Cash App, where the statement text does not always match the brand you remember.

How to verify the charge

Start with the charge date and amount from your bank app, then check your email for invoice receipts around that date. Search for invoice emails, payment confirmations, or messages from a service provider you worked with. If you run a business, also check shared cards and bookkeeping records.

Next, contact the merchant shown on the invoice and ask them to match the exact amount and authorization timestamp. If they confirm the payment was processed via Wave, request an itemized receipt or invoice copy for your records. This is the fastest way to confirm a legitimate payment.

If you cannot identify the transaction, contact Wave support through their Help Center request flow. Wave indicates support is handled through chat/email channels rather than an inbound phone line, so keep documentation ready: amount, date, last four digits of card, and any invoice references.

How to stop or cancel future charges

Wave is the processor, so cancellation usually happens with the business that billed you. Ask that business to stop recurring billing and confirm cancellation in writing. If they agree to refund, card refunds commonly post in a few business days, while bank-linked refunds can take longer.

If the merchant is unresponsive, ask your card issuer to block future charges from that merchant profile and consider replacing the card if unauthorized attempts continue. Keep screenshots of cancellation requests and all replies.

How to dispute a WAVE charge

If the charge is unauthorized, first contact your bank or card issuer immediately and report it as unknown or fraudulent. Most issuers provide dispute categories such as card-not-present fraud, duplicate processing, or service not received. Submit evidence: invoice copies, cancellation emails, and merchant communications.

If the charge is recognized but the service was not delivered, try merchant resolution first, then escalate through your issuer if needed. Disputes are time-sensitive, so act quickly once you decide to challenge the charge.

In short: many WAVE charges are valid payments to small businesses using Wave. Verification is usually straightforward with the invoice amount and date, and disputes should be filed promptly when authorization cannot be confirmed.
