Agentis vs Checkout Blocks

Quick Verdict

Checkout Blocks is a no-code checkout ui customization, upsells, and content blocks via shopify checkout extensibility tool. Agentis works after an order is placed and before it ships: within 60 seconds it computes the order's true net margin from NetSuite COGS, freight, fees, and FX, then flags it or holds it before fulfillment under rules you approve. They solve different problems and often run side by side.

The Core Difference

Checkout Blocks excels at no-code checkout ui customization, upsells, and content blocks via shopify checkout extensibility. That is its job, and the strengths and limitations below are judged on margin protection only, not on everything the product does.

Agentis sits at a specific point in the order lifecycle: between order placed and order shipped. Within 60 seconds of each order on your Shopify, Shopify Plus, or SHOPLINE store, it computes true net margin using live COGS from Oracle NetSuite plus freight, fees, and FX. Orders below your margin floor are flagged with the leak and a recommended fix, or automatically held before fulfillment under rules you approve, and every decision is logged to the Evidence Ledger.

The result: you catch a below-margin order while it can still be fixed, instead of finding it at month-end close.

When to choose Checkout Blocks

Choose Checkout Blocks if you want no-code control over the checkout experience on Shopify Plus (custom content and fields, upsells and order bumps, and tidy delivery/payment method labels); as a first-party, free-for-Plus app it is an easy addition. It is complementary to Agentis, not a competitor. Checkout Blocks acts in checkout and decorates the cart; Agentis acts after the order is placed and before it ships, deciding whether the order is profitable. Checkout Blocks' economic controls stop at static order-value limits and discounts you configure by hand, with no view of live cost. Agentis computes each order's true net margin from live NetSuite COGS, freight, fees, and FX within 60 seconds and flags or holds below-floor orders before fulfillment. The two coexist cleanly: one shapes how checkout looks, the other checks that each order is worth fulfilling as-is.

Checkout Blocks Strengths

Now a first-party Shopify app and free for Shopify Plus merchants (it was $99/mo before Shopify acquired it from Gadget in June 2024)
Drag-and-drop content blocks, custom fields, and AI upsells / order bumps across the checkout, Thank You, and Order Status pages
Hide, rename, and reorder delivery and payment methods, and set minimum/maximum order-value limits without code
Integrates with Translate & Adapt, and supports custom order and shipping discounts (advanced features gated to Shopify Plus)

Honest Assessment

Where Checkout Blocks falls short for margin protection

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

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.
