Your second payment is due 14 days after your first payment is complete — for portal, mortgage, car and student-loan payments that's 14 days after the first charge to your card; for direct rent it's 14 days after the payment reaches your landlord.
You'll see your exact second payment due date in your Split Pay account and in the confirmation email from us.
If you pay through a portal, your portal decides when it requests the first payment; your second-payment date can be moved if you need to.
