A secure and global payment processor which has recently merged to become the largest payments processor in the United States, WorldPay asks merchants to sign up for three years. If you terminate your contract early, there’s a hefty fee to pay. However, this should not necessarily be seen as a negative trait; just make sure you research the service well before signing up, as it is a worthwhile investment. It does not use a third party processor, which means all transactions are managed on site with top security. The offer virtual terminals, QuickBooks integration, omni-channel payments, analytics, fraud and risk management and a treasury service. Prices are not transparent, however, so again, make sure their customer services department fills you in before signing on the dotted line.
