United Payment Services offers Check Services programs to benefit the needs of each individual merchant. We are connected to several negative check files and verification systems to ensure the best possible service for our merchants. With check conversion technology, merchants can accept checks in the same manner as they would accept a credit card. Merchants can see immediate protection - and consequently savings - from bounced checks, bank fees and time, by using Check Guarantee or Conversion services. Additional features include stop payment protection, electronic deposits, 90-day same-as-cash, as well as several other options and premiums. Check Guarantee and Conversion offers a wealth of services beyond the basic protection from bad check writers. The service also offers additional and flexible payment options for your customers.
