Why it shows up like this
Finding STAX* SUBSCRIPTION POS on your business bank statement indicates an authorized payment to Stax Payments, LLC for Stax Subscription Merchant Processing (Fattmerchant) software and credit card processing services. This monthly SaaS fee covers wholesale interchange-plus merchant accounts, virtual terminal access, and payment gateway tools. Business owners depend on these payment systems for retail and online sales, which explains why recurring monthly withdrawals prompt careful administrative reviews.
