Connect your billing, set commission rules and launch same day. We integrate natively with Stripe, Paddle, Chargebee, Recurly, and Braintree. Every billing event flows through: upgrades, downgrades, renewals, refunds, and cancellations each adjust commissions automatically, so payouts always match revenue. Payouts can run fully auto-managed, or in bulk via PayPal and Wise. Tax forms (W-9/W-8BEN) are collected before money moves and invoices are generated on every payout, cutting out most of the admin that normally comes with running a program. Your promoters work from a dashboard carrying your brand, with their links, coupon codes, and earnings in one place. On your side: advanced 18-point reporting, custom commission structures from flat fees to multi-tier, fraud detection, and broadcast emails to your entire promoter base. Launch your program today! 14 days free trial. No credit card needed. 64 Ratings Visit Website Auth0 Auth0 takes a modern approach to Identity, providing secure access to any application, for any user. Safeguarding billions of login transactions each month, Auth0 delivers convenience, privacy, and security so customers can focus on innovation. Auth0 is part of Okta, The World’s Identity Company™. Auth0 lets you quickly integrate authentication and authorization for web, mobile, and legacy applications, with new Fine Grained Authorization (FGA) that goes beyond role-based access control. Authenticate users across all applications with a customized, secure, and standards-based single login. Universal Login connects users to a central authorization server. Credentials aren’t transferred across sources, which boosts security and protects against phishing and credential stuffing attacks. OAuth 2.0 recommends that only external user agents (like the browser) be used by native applications for authentication flows. Auth0’s Universal Login achieves this while enabling SSO. 1,069 Ratings Visit Website FusionAuth FusionAuth is a modern, developer-focused identity and access management platform built to give you full control over your authentication stack. Whether you’re building a startup app or managing enterprise-scale infrastructure, FusionAuth delivers all the must-have features — from login and SSO to advanced protocols like OAuth2, OIDC, SAML, and WebAuthn — in a self-hostable or cloud-native package. Designed with developers in mind, FusionAuth integrates seamlessly with any language, framework, or architecture. Every capability is API-first and built for extensibility, so you can tailor authentication workflows without getting locked into rigid, inflexible systems. FusionAuth supports all the key use cases — user registration, multi-factor authentication (MFA), passwordless login, role-based access control, and more — while helping you stay compliant with GDPR, HIPAA, PCI, and other regulatory standards. 191 Ratings Visit Website Regpack Regpack is an online registration and payment platform built for programs, not subscriptions. It centralizes enrollment, data collection, and payments in a single system, so you can manage participants, streamline operations, and eliminate manual processes. Used by camps, courses, afterschool programs, and multi-program organizations, Regpack connects registration forms, payment workflows, and reporting in a way subscription billing tools can't. Instead of forcing your process into recurring billing logic, Regpack is designed to reflect how programs actually operate, from first sign-up through final payment. With features like customizable registration flows, flexible payment plans, automated invoicing and reminders, and real-time reporting, Regpack gives you full visibility into your enrollment and revenue. Whether you are running a single program or managing multiple sessions and locations, everything stays connected in one place. 393 Ratings Visit Website eMembership for Labor Unions eMembership is the most powerful and flexible membership and dues system on the market. Built specifically for labor unions, eMembership is easy to configure, easy to use and easy to manage. eMembership has everything you need to effectively manage your labor union. Members, employers, contracts, dues, payment processing, invoicing, grievances, organizing and unlimited reporting. We built the first version of eMembership in 2008 to address a growing problem faced by labor unions – aging computer systems that no longer supported the organization or the industry. Our goal was to build a system that could evolve with the times. We used contemporary software and a modular design that can support the unique requirements of any organization. We host eMembership in our highly-redundant, SSAE-16 compliant data center, so we take care of hardware, software, operating systems, security patches, system monitoring, bandwidth, backups…while you focus on your core business. 19 Ratings Visit Website Revaly Revaly is a Payment Performance Management platform designed to ensure that every legitimate transaction succeeds, protecting the recurring revenue businesses depend on.

The platform continuously analyzes routing errors, behavioral patterns, and ecosystem signals to turn unpredictable payments into predictable revenue. Subscription-based companies rely on Revaly to lift approval rates and compound revenue growth without disrupting their existing billing stack.

About flatpass sells Discord roles as subscriptions, set up in four steps: add the bot, connect your own Stripe account, pick a role, set a price. Members pay on an invite page in your server's own look, or from a price card pinned in the server, and get the role the moment payment clears. It comes off when the subscription ends, is refunded or charged back. Payments are Stripe Connect direct charges on the seller's own account. You are the merchant of record, money lands on Stripe's normal payout schedule, and flatpass never touches it. Authorization runs through Stripe Connect, so flatpass never asks for an API key. Pricing is a flat monthly fee, never a percentage of sales: free up to 15 paid members, then from $29/month. One account covers every server you run, with paid members counted across all of them together. Already selling elsewhere? Run flatpass alongside it and move members over as they renew. Discount codes work at checkout.
