Tool Comparison
Checkout Blocks vs Agentis: Checkout UI Builder vs Margin Governance
By Herzel MishelFounder, AgentisLast reviewed
Comparing Checkout Blocks and Agentis? They both live at the checkout, but they do opposite jobs. Checkout Blocks is a first-party Shopify app — acquired from Gadget in 2024 and now free for Shopify Plus — for no-code Checkout Extensibility: drag-and-drop content, custom fields, AI upsells, and hiding/renaming/reordering delivery and payment methods. Agentis is a real-time profit firewall: it reads live NetSuite COGS, freight, and FX and blocks below-floor orders, MAP violations, and coupon-stacking at checkout in under 10ms. One decorates the cart; the other decides if the cart is profitable. Checkout Blocks controls what displays; Agentis controls whether the order should clear. They are complementary and commonly run side by side.
Why Merchants Look for Checkout Blocks Alternatives
Checkout Blocks focuses on no-code checkout ui customization, upsells, and content blocks via shopify checkout extensibility. That works well for shopify plus merchants customizing the checkout, thank you, and order status pages without code, but it leaves gaps that matter for high-volume Shopify Plus operations:
- Controls what displays at checkout — content, fields, upsells, method labels and order — not whether an order clears a profit floor
- Its only economic levers are static order-value limits and manually configured discounts; it is blind to live unit economics
- No COGS, freight, or FX awareness, and no NetSuite integration — it cannot compute per-order margin
- No real-time margin enforcement: a checkout it has decorated can still confirm below margin, and Checkout Blocks never sees the cost side
Agentis is purpose-built for what Checkout Blocks cannot do: enforcing your profit floor at checkout in real-time. While Checkout Blocks reports on margins after the fact, Agentis evaluates every order against live COGS from NetSuite, freight zone costs, and FX rates (in under 10ms) before the order is confirmed.

Frequently Asked Questions
Is Checkout Blocks the same as Agentis?
No. Checkout Blocks is a no-code checkout UI and upsell builder — a first-party Shopify app, free for Plus merchants — that controls what displays at checkout: content, custom fields, upsells, and delivery/payment method labels and order. Agentis governs checkout economics, reading live NetSuite COGS, freight, and FX to block orders below your profit floor. One decorates the cart; the other decides if the cart is profitable.
Should I use Checkout Blocks or Agentis?
Use Checkout Blocks if you want to customize how the checkout, Thank You, and Order Status pages look and behave — content, fields, upsells, and method customization — with no code; since it is free for Shopify Plus, it is easy to add. Use Agentis if you need to guarantee each order clears a margin floor after real costs and discounts. Their jobs do not overlap, so many Plus merchants run both.
Does Checkout Blocks enforce a profit floor?
No. Its only economic levers are static minimum/maximum order-value limits and manually configured discounts; it has no COGS, freight, or FX awareness and no ERP integration, so it cannot tell whether an order is actually profitable. A checkout it has styled can still confirm below margin. Agentis adds that missing layer, evaluating live unit economics on every order at checkout.
Did Checkout Blocks used to cost $99/mo?
Before Shopify acquired it from Gadget in June 2024 it was a paid third-party app (about $99/mo). It is now a first-party Shopify app and free for Shopify Plus merchants, with advanced features gated to Plus. Note that any “$19/mo Checkout Blocks” you may see refers to an unrelated third-party clone, not this app.
