Agentis Solution
Custom Checkout Rules for Shopify — With a Live Profit Brain
Most custom checkout rule apps build the logic gates: hide a payment method, block an address, gate a shipping option. Agentis adds the part they're missing — live COGS and margin awareness — so your validation, payment, and discount rules can decide on profit, not just attributes.
The Problem
When teams search for custom checkout rules on Shopify, they usually want one of two very different things. The first is cosmetic and attribute-based logic: hide express payment for B2B carts, block PO boxes, restrict a shipping method by zip code, require a minimum quantity. There are good apps for that. The second — far harder and far less served — is financial logic: 'allow this discount only if the cart stays above margin,' 'block this order if its true landed cost exceeds the price,' 'cap this promo by aggregate margin impact, not redemption count.' Shopify's native settings and the cosmetic rule builders can't express the second kind, because they have no access to your cost data. So the rule that actually protects the P&L is the one no tool will build for you.
How Agentis Solves It
Agentis is the rules engine for the financial half of the problem. It plugs live NetSuite COGS, freight zone costs, and real-time FX into Shopify's checkout validation, payment, and discount surfaces, so a 'custom checkout rule' can finally be conditioned on margin instead of only on attributes. Define rules like 'reject if effective margin < floor,' 'trim the discount stack to hold MAP,' or 'disable this code once its margin impact crosses a threshold,' and Agentis evaluates them on every cart in under 10ms, returning approve, modify, or reject. To set expectations honestly: this is not a cosmetic rules builder. Cosmetic rule apps such as PowerX and SMART Checkout Rules build the attribute-based logic gates — hiding methods, blocking addresses, gating fields. Agentis adds the financial brain those gates lack. The two are complementary: use a rules app to shape the checkout's behavior by attributes, and Agentis to make the rules that depend on cost and margin.
Key Benefits

- Run on Shopify's validation, payment, and discount surfaces with one margin-aware engine
- Pairs cleanly with attribute-based rule apps instead of replacing them
- Configure through a UI with sub-10ms decisions and no Functions code

Built for
Shopify Plus merchants who want custom checkout rules that decide on profitability — finance and ops teams whose real requirement is margin-aware logic, not the cosmetic attribute rules that existing checkout-rule apps already cover.
Frequently Asked Questions
Is Agentis a custom checkout rules builder for Shopify?
It is a custom checkout rules engine for the financial dimension specifically. If your rule depends on cost or margin — 'allow this discount only above floor,' 'block below-margin orders,' 'cap a promo by margin impact' — Agentis is built for exactly that, because it has live COGS, freight, and FX. If your rule is cosmetic or attribute-based — hide a payment method, block an address, restrict a shipping option — that's a different category, and dedicated rule apps already handle it well.
How is this different from apps like PowerX or SMART Checkout Rules?
Those apps build the logic gates: attribute-based rules that hide, block, gate, or reorder checkout elements based on cart contents, customer tags, or location. They're good at it. What they don't have is your cost data, so they can't make a rule that depends on margin. Agentis adds that financial brain — it conditions rules on live COGS and landed cost. Many stores run a cosmetic rules app for attribute logic and Agentis for the margin logic, side by side.
What kinds of margin-based rules can I create?
Common ones include: reject any order whose effective margin falls below a configured floor; trim a discount stack so the cart stays above floor or above MAP; disable a promo code once its aggregate margin impact crosses a threshold regardless of stated redemption limits; and apply tighter floors to SKUs sourced from high-cost or high-tariff origins. All are scoped per SKU, category, freight zone, and customer segment.
Do I need to write Shopify Functions code to use these rules?
No. Agentis is configured through a UI and integrates with Shopify Plus checkout extensibility at the validation hook without you writing Functions in Rust or JavaScript. You define margin-aware rules as policy, test them in shadow mode against live traffic, then switch to enforce mode — no engineering runtime to build or maintain.
