When a customer sends cryptocurrency to an online store, the blockchain records the transaction, yet the merchant's system may not reflect the payment. What begins as a routine sale becomes a support ticket as staff search for the transfer and customers question where their money went.
This disconnect represents a significant cost that many e-commerce and subscription businesses overlook when evaluating crypto payment options. The issue is becoming more relevant as commercial crypto adoption grows. Visa reported in October that business and commercial programs accounted for nearly 17% of stablecoin-linked card volume in fiscal 2026.
The Cost of Failed Payments
A study of 150 financial-institution executives found that 37% faced costs exceeding $20 per failed or delayed payment. While banks and online merchants operate differently, the underlying challenge mirrors the crypto space: someone must trace transfers, reconcile accounts, and handle manual interventions.
Common issues include customers sending the wrong token, selecting the wrong blockchain, or omitting required destination tags. Even successful transfers can create problems when account information mismatches prevent access to purchased services.
Refund Timelines
Data from merchant refunds between September 2025 and August 2026 showed a median gap of 3.7 days between an original payment and the merchant initiating a refund. This timeframe includes customer decision-making time but demonstrates the delay before refund processing even begins.
Speed varies by process. One study comparing refund methods found a median of 21 minutes to send funds when email confirmation was skipped, compared with 4.3 hours when verification was required. Removing checks accelerates refunds but increases the risk of sending funds to incorrect addresses.
What Providers Can Handle
NOWPayments, originally launched by ChangeNOW, illustrates how payment gateways can manage problem cases. The provider documented examples including manual completion of a $105 ETH payment within approximately one minute of customer approval, a Bitcoin refund exceeding $400 resolved within roughly two days, and resolution of an access issue caused by mismatched email within 12 minutes.
NOWPayments reports that 97%–98% of support chats receive initial responses within three minutes, though actual resolution takes longer. The gateway offers payment-status notifications and optional automatic processing for certain wrong-network deposits, though some refunds still require verification and recovery is not guaranteed.
In September 2026, NOWPayments reported 103.8% year-over-year growth in successful integrations and 92% year-over-year growth in partners making their first transaction.
Evaluating a Payment Provider
For merchants considering crypto payments, the practical assessment is direct: present a prospective provider with a real failed-payment case and ask who traces the transfer, validates refunds, and confirms resolution. Track the staff time spent on each exception alongside transaction fees.
As payment volume grows, support workload should not scale proportionally. The saved working hours may prove as valuable to a business as the advertised processing fee.
