Payments for marketplaces and ecommerce.

With seamless card acquiring, crypto payments, BNPL, A2A bank transfers, Biometric readers and flexible split-payment logic, we turn payment friction into a competitive advantage.

We go beyond simple processing by eliminating the wait times inherent in B2B and consignment sales for e-commerce and marketplace sales.

Why limit yourself to general-purpose gateways

Our seamless checkout process involves any payment method your customers choose.

Generic gateways reject valid bookings

Standard fraud filters often flag high-value legitimate transactions, causing unnecessary declines.

Card limits block payments

Customers often hit daily spending limits on expensive bookings. Why limit yourself to card payments only.

Abandoned checkouts eat your margin

Our checkout process makes sure to suggest a new payment method instead of a simple decline.

Split one payment into many. Automatically.

Slize enables a single customer payment to be split in real time and automatically distributed to multiple parties, without changing your existing payment provider.
