Freemium
Free for merchants who exclusively use Shift4 Payments as their card processor, with no added transaction fee on top of processing; merchants using another payment processor or based outside the U.S. pay for a standard plan instead — Shift4Shop's own site cites an unlimited 'End-to-End eCommerce' plan at $41/month.

Pros & Cons
subbly
Pros
Purpose-built specifically for subscription/recurring-revenue commerce rather than a generic storefront
Free migration path from Shopify, WooCommerce, Wix, Recharge, and Cratejoy
Includes churn-prediction AI and dynamic bundle/upsell tools out of the box
API/SDK access on higher tiers for custom development
Cons
Entry-level Lite plan excludes the website builder, limiting it to subscription management only
Transaction fees (1-2% plus a flat fee) apply on top of monthly subscription cost on most plans
Custom API access is gated behind the higher-priced Advanced and Subbly X tiers
shift4shop
Pros
Genuinely free software tier for merchants who use Shift4 Payments, with no separate transaction fee layered on top
All-in-one feature set — website builder, product/inventory management, marketing, and SEO tools are bundled rather than sold as add-on apps
100+ included, SEO-optimized, mobile-responsive themes plus a free domain and SSL, reducing setup costs
Long operating history (21+ years, formerly 3dcart) with an established merchant base (~22k merchants) suggesting platform maturity
Cons
The free plan is conditional on exclusively using Shift4 Payments for card processing, which limits payment-provider flexibility for merchants who want the no-cost tier
As a hosted, all-in-one platform, merchants have less flexibility to swap in third-party theme/checkout systems compared to fully headless or open ecommerce stacks
Publicly listed pricing beyond the single $41/month End-to-End plan is not consistently detailed on Shift4Shop's own marketing pages, making full plan-to-plan comparison harder without contacting sales
