For example, a customer may be approved for $2,000 but only needs $600 to cover a car repair. They choose a loan repayment plan to pay off that $600, pay some amount of the purchase up front, and then pay the rest in monthly installments.

• Merchants set minimum and maximum qualifying purchase amounts
• Customers can earn credit card rewards on their purchases
• No application — customers with an eligible credit card can simply select Splitit as a payment option
• Integrates with major eCommerce platforms such as Magneto, Shopify, & WooCommerce
• POS integration with Ingenico terminals
• Short- and long-term repayment plans

Splitit charges merchants 1.5-6.5% per transaction, plus a flat fee of $1.50.

Splitit does not charge customers any fees. However, if customers don’t pay their balance in full at the end of the month, they could be charged interest fees from their credit card issuer, as with any credit card balance.

Customers must meet the following requirements

• 18+
• Have an eligible credit card
• Have enough available credit to cover full purchase amount

Customers do not have to undergo a credit check during the loan application process. However, Splitit does make sure that they have enough available balance on their credit card to cover the full balance of their transaction before being approved for a loan.

For example, if your customer wants to buy a $1,000 laptop, they must have at least $1,000 available on their credit card to cover the cost of the purchase. They may have to pay $200 upfront, and Splitit will put a preliminary hold of $800 on their card. Once they pay the next $200 installment, the hold reduces to $600, and so on, until the purchase is paid off.

Splitit installment options range from 3-24 months, depending on the retailer. These are monthly installments and the customer must pay off their credit card balance every month.
