Profit Governance

Checkout Governance

Definition

The set of rules applied inside checkout that decide which discount combinations, shipping options, payment methods, and order configurations a buyer can complete. It acts before the order is placed, which makes it distinct from post-order margin controls that act before fulfillment.

Checkout governance is the part of commerce policy that lives inside checkout: the rules that decide, while the buyer is still completing the purchase, what the order is allowed to look like. Typical questions it answers: 'Can WELCOME10 combine with SUMMER20?', 'Should free shipping apply to this zone?', 'Should this payment method be offered to this customer segment?', 'Does this B2B cart meet the minimum quantity?'. On Shopify, the surfaces are native discount combination settings and usage limits, Shopify Functions (discount, delivery customization, payment customization, cart transform, and the Cart and Checkout Validation Function), and Checkout Extensibility for UI changes on Shopify Plus. Shopify Scripts, the older Ruby-based surface, was retired: Shopify froze Script editing on April 15, 2026 and stopped executing Scripts on June 30, 2026, so checkout governance that used to live in Scripts now has to be rebuilt on Functions and discount settings. Three implementation patterns are common: adjusting the offer (applying only the best discount), hard rejection (a validation error the buyer must resolve), and observe-only modes used while a rule is being calibrated. The strengths of checkout governance are that it acts before anything is charged and that it shapes the buyer's choices directly. Its limits are that rules see the cart rather than live ERP cost, run under Shopify's resource limits, are customer-facing, and usually need developer time. Margin questions that depend on true cost, such as whether this order still clears its floor after COGS, freight, fees, and FX, are hard to answer reliably inside checkout. Agentis does not operate in checkout and is not a checkout governance tool. It works after the order is placed: within 60 seconds it computes each order's true net margin and flags it or holds it before fulfillment under rules the merchant approves. Many merchants use both: checkout governance for rules the cart can decide, and a post-order margin check to catch the orders that clear checkout but would ship below floor.
