Adyen provides a unified platform that handles your entire payment flow from start to finish. Instead of managing separate gateways, risk tools, and processors, you can run your whole operation through one infrastructure. This setup gives you a single view of your customers across online stores, mobile apps, and physical locations, making it easier to offer flexible shopping experiences like buying online and returning in-store. You can accept hundreds of local payment methods globally while using built-in data tools to recognize loyal customers and block fraudsters. The platform is built for growth, allowing you to expand into new markets quickly without changing your technical setup. It is particularly effective for mid-market and enterprise businesses that need to simplify complex global payment operations and improve authorization rates.

Zeffy is a specialized fundraising platform designed exclusively for nonprofits who want to keep 100% of their donations. Instead of charging platform fees or taking a cut of credit card transactions, the system relies on voluntary tips from donors. You can manage everything from simple donation forms and peer-to-peer campaigns to complex event ticketing and lottery management without worrying about hidden costs or monthly subscriptions. You can easily track your donor database, automate tax receipts, and sell memberships or merchandise through a single dashboard. It solves the common problem of losing 3-5% of every gift to processing fees, making it an ideal choice for small to mid-sized charities, schools, and community groups looking to maximize their impact. The platform is accessible to any registered nonprofit in North America looking for a transparent, zero-cost financial solution.
