Our partial payment solution is directly integrable with our Shopify module. Our price widget is also easily installed with this module. Find documentation for how to set it up here.
We are an integratable payment option with almost all other shop systems, which is supported by the following gateways, as we are integrated in their gateway:
Quickpay
OnPay
Frisbii
Pensopay
Freepay
Swiipe
However, with this solution, our price widget has to be installed with custom coding. We, of course, do this for you free of charge. However, you can also read more about the setup of our price widget here.
