The GoodPayments Project: Beginning in 2019, all new merchant accounts will generate donations each month to Feeding America®, the U.S.' largest domestic hunger relief organization. We feel strongly about this - especially when it comes to children. We have written a specific algorithm to generate donations based on a business' monthly volume and transactions.

​

In addition to our payments and marketing services, we also offer Professional Tax Services for our clients, at much-reduced rates. Sole Prop/S Corp/LLC/Partnerships and Non-Profits. Our tax pros have over 3000 cases and 15 years worth of experience, in both tax prep and tax resolution. With our active Enrolled Agent status, we can act as your liaison with the tax authorities - most of the time for no cost (for merchant clients). Save time and stress! We would love to help protect your business, and help it succeed.
