ReCharge vs Bold vs Skio vs Smartrr, which subscription provider for Magento and why?

ReCharge is the Shopify default; on Magento your real choices are Bold, Skio, Smartrr, and custom. Trade-offs:

• Bold Subscriptions for Magento, oldest, most mature option. Solid for “simple monthly sub” flows. Weakness: bundle subs and swap-out flows feel clunky (UI built before modern sub UX standards). Pricing ~$199, $999/mo + per-tx. Best fit: $1M, $5M brands with straightforward monthly subs.
• Skio, newer (founded 2020), built by ex-Shopify subscription engineers. Cleanest UI, modern customer portal (passwordless login, swap-out, surprise & delight built-in). Magento integration is via API + custom storefront layer. Pricing 1% of sub GMV. Best fit: $2M, $20M brands who care about CX. Athletic Greens-like polish.
• Smartrr, white-glove for premium / enterprise. Native predictive analytics, AI-driven retention, member-only perks built-in. Pricing 1-2% of sub GMV. Best fit: $5M+ brands willing to pay for retention sophistication.
• Custom Magento-native subs, for enterprises ($10M+) who want full data ownership, custom billing logic, or zero ongoing SaaS fee. ~$25k, $80k to build, ~$5k, $15k/yr to maintain. Worth it above $5M sub GMV when you’re bleeding $50k+/yr in SaaS sub fees.

My default: Skio for new Magento supplement builds at $2M, $10M because the customer portal alone saves you 20% churn vs Bold. Smartrr above $10M. Custom only when the math demands it.
