Checkout Blocks vs Agentis: Checkout UI Builder vs Margin Governance

Comparing Checkout Blocks and Agentis? They do different jobs at different moments. Checkout Blocks acts in checkout: it 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 acts after the order, before fulfillment: within 60 seconds of each order being placed, Agentis computes its true net margin from live NetSuite COGS, freight, fees, and FX, then flags the order or holds it before fulfillment under rules you approve. One decorates the cart; the other checks whether the resulting order is profitable. They are complementary and can 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 per-order margin check: an order placed through a checkout it has decorated can still go through below margin, and Checkout Blocks never sees the cost side

Agentis covers a job Checkout Blocks is not built for: checking each real order's true net margin after it is placed and before it ships. Within 60 seconds of every order, Agentis computes net margin from live NetSuite COGS, freight, fees, and FX, then flags the order or holds it before fulfillment under rules you approve, and logs the decision to an Evidence Ledger. It is often used alongside Checkout Blocks, not instead of it.

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 works after the order is placed: it computes the order's true net margin from live NetSuite COGS, freight, fees, and FX within 60 seconds and flags or holds orders below your profit floor before they ship. One decorates the cart; the other checks whether the resulting order is profitable. Checkout Blocks' strengths are drag-and-drop content blocks and custom fields across the checkout, Thank You, and Order Status pages, AI upsells and order bumps, the ability to hide, rename, and reorder delivery and payment methods, and minimum and maximum order-value limits without code. Its economic levers stop there: it has no COGS, freight, or FX awareness and no NetSuite integration, so it cannot compute per-order margin. Treat it as a checkout experience tool and look elsewhere for anything that depends on knowing what an order costs.

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 each order checked against a margin floor after real costs and discounts, with below-floor orders flagged or held before they ship. Their jobs do not overlap, so they can run together. Checkout Blocks also integrates with Translate & Adapt and supports custom order and shipping discounts, with advanced features gated to Shopify Plus. None of those features see the cost side, so an order from a checkout it has decorated can still go through below margin. The decision is not one or the other; it is whether you need checkout customization, per-order margin checks, or both, and each need points to a different tool.

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. An order placed through a checkout it has styled can still go through below margin. Agentis adds that missing layer after the order is placed, computing each order's true net margin within 60 seconds and flagging or holding it before fulfillment if it falls below your floor. Checkout Blocks' strengths are all on the presentation side: drag-and-drop content, custom fields, AI upsells and order bumps, and control over how delivery and payment methods display. Static order-value limits can stop very small or very large orders, but they cannot distinguish a profitable order from an unprofitable one of the same value. Check whether your current checkout tooling ever reads cost data; if it does not, no configuration of that tooling will produce a profit floor.

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. Whatever it once cost, the app's scope has not changed: it controls what displays at checkout, including content, custom fields, upsells, and delivery and payment method labels and order, and it has no COGS, freight, or FX awareness. Its economic levers remain static minimum and maximum order-value limits and manually configured discounts. Merchants evaluating it should decide based on whether they need no-code checkout customization, since margin enforcement is a separate capability it does not provide.
