Subscription engine, ReCharge, Bold, Skio, Smartrr, or custom?

Pick by scale and roadmap:

• ReCharge, the default. Native Magento connector, weekly/biweekly/monthly cadence, skip/pause/swap, dunning recovery (3 retries over 5 days), customer portal. Pricing: ~$99/mo + 1.0% of recurring transactions (Pro plan). Best for 500-50k active subs.
• Bold Subscriptions, better customer portal UX, cheaper at low scale. ~$49.99/mo + 1% transaction fee. Magento integration via Bold Commerce official module. Best for 100-10k active subs.
• Skio, newer, Shopify-Plus-native, just launched Magento connector beta in 2024. Strong upsell-in-portal mechanics (passwordless login, in-portal swap). Good if you want best-in-class portal UX. Pricing: ~$499/mo + 1% transaction fee.
• Smartrr, community-features-focused (member-only content, early-access drops, gifting). Good for premium meal-kit brands ($60+/box). ~$199/mo + 1% transaction fee.
• Custom in-house, only at $50M+ GMV when 1% transaction fee becomes the largest line item ($500k+/yr). Build a custom recurring engine on Magento as the commerce layer. 6-12 months of dev.

At <5k subs the SaaS savings are not worth custom dev. Above 50k subs the fee math flips. Re-evaluate quarterly.
