Accelerate your cash flow

Payments for marketplaces and ecommerce.

With seamless card acquiring, crypto payments, BNPL, A2A bank transfers, 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 general-purpose gateways fail you

Stripe and Adyen are great for $50 subscriptions, but they aren't optimized for high-value transactions.

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. Without a bank transfer option, the sale is lost.

Card fees eat your margin

Paying 2.9% + 30¢ on a €5,000 booking means losing €145+. Bank transfers cut this cost significantly.

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.

Slize applies predefined split rules
Funds are distributed instantly to each recipient

Turn failed payments into completed revenue.

Slize intelligently routes transactions and provides instant fallbacks to ensure you capture every booking.

Immediate bank transfer fallback

If a card fails, we instantly offer a direct bank transfer option within the same flow.
