Cheddar Up

Cheddar Up is an all-in-one online platform that helps groups and communities collect payments and forms in one place. Purpose-built for PTAs/PTOs, booster clubs, youth sports teams, nonprofits, schools, clubs, HOAs, churches, and other volunteer-led organizations, it lets organizers collect dues, registrations, donations, event fees, fundraisers, and group gifts without any technical setup. It combines online payments (credit card, e-check, Apple Pay, Google Pay, and Link), custom forms, waivers, sign-ups, recurring payments, itemized storefronts, automated tracking and reporting, and multi-manager team administration. For technical users, Cheddar Up exposes an embeddable JavaScript SDK (a guest-facing Checkout component instantiated via CheddarUpWidgetFactory), API keys on the Team plan, and a native webhooks integration for syncing collection and payment events to external apps.

Cheddar Up is profiled on the APIs.io network. Tagged areas include Company, Payments, Group Payments, Fundraising, and Nonprofits.
