About NETbilling
NETbilling is a U.S.-based payment processing company that provides merchant accounts, multi-currency transaction processing, and a PCI-compliant payment gateway for e‑commerce, mobile, and point‑of‑sale businesses. They are particularly active in high-risk verticals such as adult content, membership, and subscription websites, and also operate a full-service call center that handles billing inquiries, membership access issues, and order placement for merchants’ customers.([netbilling.com](https://www.netbilling.com/transaction-processing/payment-gateway/?utm_source=openai))
A charge showing as "ETM-CS.COM" on your statement typically indicates that your card was run through NETbilling’s gateway using that specific billing descriptor, often on behalf of an online subscription or digital-content merchant (for example, some adult membership sites list NetBilling (ETM-CS.COM) as their designated e-ticket supplier and access management provider).([new.allover30.com](https://new.allover30.com/Recent_Updates?nats=ODoyOjE&utm_source=openai)) The transaction may represent a one-time purchase, a recurring subscription renewal, a trial that converted to a paid plan, or a reattempted billing on an existing membership. In some cases, small test or verification charges may appear temporarily when a merchant validates a card.
If you don’t recognize the charge, first think about any recent online subscriptions, downloads, or memberships—especially on sites that might use a third-party biller rather than their own name on your statement. You can usually identify the underlying merchant by checking recent confirmation emails or logging in to accounts created around the date of the charge. If you still can’t match it, NETbilling’s customer support and the website noted on your statement (often etm-cs.com or netbilling.com) can help look up the transaction using your card details and date/amount of the charge. They can advise which merchant billed you, assist with cancellations or refunds if eligible, and clarify whether the charge is recurring.
