Founder Nature House

OPP helped us tremendously with the entire integration of payments on our rental platform. The checkout is entirely integrated fitting our own design, and the full payment journey is seamless, ensuring that neither renter or hosts notice there is an external party facilitating the payments.

Annemarie Buitelaar

CEO Adevinta Benelux (Marktplaats & 2dehands.be)

We've been successfully collaborating with OPP for almost a decade enabling millions of buyers and sellers to securely pay and trade on the largest marketplace in the Netherlands; Marktplaats.

Fred van der Stappen

Executive member Geldvoorelkaar.nl

OPP is a highly specialized partner with experience in the dynamics of crowdfunding platforms and can support us, among other things, in working with a wallet structure and setting up multi-split payments.

Nicholas Latham

Co-founder PetBnB

Easy, smooth payments and fast payment confirmation are key to our platform. These things simply need to work. If it doesn’t, it kills the trust our users have in the platform, which affects our brand. At the end of the day, we only make money if people pay. OPP is therefore strategic to our success.

Case

Marktplaats increased their succesful transactions by over 300% using our equal transfer solution

Marktplaats in the Netherlands biggest online marketplace. It’s kind of like Ebay, where people come together to sell products they don’t need anymore, or that someone else might have a better use for.
