Is Mantle (heymantle.com) shutting down?

Yes. Mantle announced on June 16, 2026 that it is winding down. Mantle Billing customers are supported until September 30, 2026, and all other Mantle services end on August 14, 2026. Shopify app developers using Mantle need to migrate before these dates to avoid billing disruption.

What is the best Mantle alternative for Shopify apps?

Baseplate is a focused, AI-native alternative to Mantle for Shopify app developers. It provides billing on top of the Shopify Billing API, best-in-class revenue analytics, entitlements and paywalls, and a one-click import from Mantle. Your billing rail never leaves Shopify, so migrating causes zero billing disruption.

Will migrating off Mantle disrupt my billing?

No. Because Shopify owns the subscription through the Shopify Billing API, your billing rail stays on Shopify when you migrate to Baseplate. You can run Baseplate in parallel for 30 days to verify your numbers match before fully switching, and you keep all of your historical data.

How much does Baseplate cost?

Baseplate is free until your app reaches $5,000 in monthly tracked revenue. Paid plans use a low, hard-capped percentage of tracked revenue or a flat fee — whichever is cheaper — so you are never penalized for growing.

◆ Billing that stays on Shopify

The revenue layer for Shopify apps.

Focused billing plus best-in-class revenue analytics. Your billing rail never leaves Shopify, you own every byte of your data, and you pay lower capped fees — not a cut stacked on top of Shopify's.

Billing on Shopify

Plans, trials, usage-based, and one-time charges — all created and collected through Shopify's Billing API. Nothing to leave.

Why Baseplate

Better than the alternatives.

Honest about the trade-offs. Shopify native is great at billing but weak at analytics; Mantle was feature-rich but is shutting down with fees stacked on top of Shopify's.
