Overview
ChaChing and Upsell.com are two distinct tools designed for different aspects of online business growth. ChaChing is a subscription billing engine that replaces Stripe Billing, offering a 50% reduction in fees while keeping Stripe for payment processing. It targets SaaS companies and subscription services that want to save money on billing without switching processors. Upsell.com (formerly ReConvert) is a post-purchase upsell and cross-sell platform built exclusively for Shopify and Wix stores. It helps merchants increase average order value (AOV) by adding one-click upsells, customizing thank you pages, and optimizing the checkout journey.

Pricing
ChaChing offers a simple pricing model: 0.35% of billing volume for small to medium businesses. Enterprise customers can get custom pricing. There are no lock-in contracts because ChaChing is built on the open-source Kill Bill engine, so you can always take your data and run it yourself. This is significantly cheaper than Stripe Billing's 0.7% fee on subscription volume.
Upsell.com uses a pay-as-you-grow model based on either revenue generated through upsells or store order volume. A free trial is available, and merchants can cancel anytime. Pricing scales with usage, making it accessible for small stores but potentially expensive for high-volume merchants.
