The short answer
ZIP CO US INC is a Buy Now, Pay Later (BNPL) installment charge from Zip Co (formerly QuadPay). When you make an online or in-store purchase using Zip, your purchase total is divided into four equal bi-weekly payments.
How Zip installment billing works
Zip Co Limited (operating as Zip Co US Inc.) is a digital payments provider that allows shoppers to split retail checkout totals into four equal installments over six weeks. If you see ZIP CO US INC, ZIP PAY, or QUADPAY on your bank or credit card statement, it indicates one of these scheduled bi-weekly installments.
When you check out with Zip, you pay 25% of the order total upfront on the transaction date. The remaining 75% is divided into three equal installments debited from your linked debit or credit card every two weeks. Zip also charges a small finance platform fee per installment (typically $1.00 to $2.00) depending on the merchant agreement.
Because installments execute automatically on fixed 14-day cadences, charges often post to card statements weeks after goods have already been delivered, leading cardholders to confuse the second, third, or fourth payment for an unauthorized billing event.
The fine print on Zip orders
- A second, third, or fourth scheduled bi-weekly installment from a past retail purchase.
- An installment platform convenience fee ($1 to $2) added to each scheduled payment.
- A late fee of $5 to $10 charged because a scheduled payment failed due to insufficient funds.
- A family member used your stored card details in their Zip app account.
Managing your installment orders
- Log into the Zip mobile app Open the Zip app and navigate to Orders to review active payment plans, merchant names, and remaining balances.
- Check linked debit or credit cards Under Settings > Payment Methods, review which payment cards are assigned as the primary payment method for upcoming debits.
- Resolve returns directly with the merchant When returning items to a retailer, the merchant issues the refund to Zip, which then credits your linked card and cancels remaining installments.
