What Stax is
Stax sells payment processing on a monthly subscription. The subscription depends on yearly processing volume: $99 a month up to $150,000 a year, $139 a month from $150,000 to $250,000, and $199 or more above $250,000. Interchange is passed through at cost with a per-transaction fee. Stax also offers built-in credit card surcharging; when a customer pays by debit, Stax lists the merchant fee as 1.25% + $0.25.

Qué es CELER Merchants
We do not process payments and we do not hold your money. We read your statement, name every fee (usually within 4 hours), then take your profile to the providers we work with and show you every offer that comes back. You choose. The provider you choose pays us, so the service is free to you. Our pricing structures carry no statement fee, no PCI fee, no annual fee, no monthly minimum and no early-termination fee, and the CELER Rate Lock fixes the markup in writing.

A subscription can make sense at steady, higher volume, because the fixed monthly fee is spread over more sales. At lower volume, the monthly fee weighs more on every sale. Compare your effective rate (total fees, including the subscription, divided by total card volume) with the offers you could get. We are happy to tell you when your current pricing is already good.

It depends on your volume, card mix and average ticket. Send a recent statement and we name every fee, usually within 4 hours, then show you the offers providers make for your account. If Stax is already the better deal for you, we tell you so.
No. In the US, Visa and Mastercard rules prohibit surcharging debit and prepaid cards. Surcharging is also prohibited in Connecticut, Maine, Massachusetts and Puerto Rico, and Quebec does not allow a fee for paying by card.
