The Quarter payment experience.


Your customer decides to pay for a purchase with Quarter.

As the initiator of the payment, a debit authorization equal to the total purchase amount is requested on his/her card.


Your customer invites the chosen participants, and pays his/her share.

The initiator invites participants by entering their email adresses and assigning them a share to pay.


Participants have 24 hours to pay their shares.

After the deadline, any unpaid shares will be withdrawn from the initiator's debit card.
