Commerce Architecture
6 termsCommerce Architecture
Composable Commerce
An architecture pattern where ecommerce capabilities (checkout, search, content, payments, fulfillment, promotions) are assembled from independent best-of-breed services rather than provided by a monolithic platform.

WASM Checkout (WebAssembly at Checkout)
The use of WebAssembly modules to run merchant-defined logic inside checkout. Shopify Functions, the replacement for Ruby-based Shopify Scripts, is the best-known implementation: logic is compiled to WebAssembly and executed in a sandbox within Shopify's checkout.
Read definitionCommerce Architecture
Shopify Functions
Shopify's platform for customizing backend commerce logic, such as discounts, cart and checkout validation, delivery and payment customization, cart transforms, and order routing. Functions are compiled to WebAssembly and run inside Shopify's infrastructure. They replaced Shopify Scripts, which stopped executing on June 30, 2026.

Margin Collision
When multiple cost factors simultaneously erode margin on a single order — e.g., a deep discount, high freight zone, and unfavorable FX rate combining to make an order unprofitable.
Read definitionMargin Analysis
Discount Stacking
When multiple discounts, such as a site-wide sale, a coupon code, and a loyalty reward, combine on a single order, compounding margin loss beyond what any individual promotion intended.

Gross Margin
The percentage of revenue remaining after subtracting the cost of goods sold, a foundational profitability metric that excludes operating expenses, taxes, and interest.
Read definitionMargin Analysis
Contribution Margin
The revenue remaining after deducting all variable costs associated with fulfilling an order, including COGS, shipping, payment processing fees, and pick-and-pack labor.

Order Profitability
The true net profit of a single order after deducting all variable costs: COGS, shipping, discounts, payment fees, fulfillment labor, and return allowances.
Read definitionMargin Analysis
Margin Leakage
The gradual, often undetected loss of profit across many orders, driven by small per-order cost overruns that compound into significant revenue erosion over time. Also called revenue leakage, a term more common in marketplace-seller (Amazon/Walmart) contexts for the same underlying pattern.

SKU-Level Profitability
The analysis of profit margins at the individual product or variant level, revealing which specific items generate profit and which consistently erode it.
Read definitionMargin Analysis
Bundle Margin Analysis
The evaluation of profitability for product bundles, where the combined price and costs of individual items create a distinct margin profile from standalone sales.

GMROI
Gross Margin Return on Investment measures how much gross profit a merchant earns for every dollar invested in inventory -- a critical metric for capital-efficient ecommerce.
Read definitionMargin Analysis
Net Profit Per Order (NPPO)
The actual dollar profit remaining on a single order after deducting all variable costs, fixed cost allocation, and marketing attribution -- the most granular unit of ecommerce profitability.

Silent Profit Killer
Any margin-eroding pattern that operates below the threshold of standard reporting, typically discount stacking, COGS drift, freight underestimation, and FX leakage.
Read definitionMargin Analysis
Yield Gap
The gap between the margin a commerce business books and the margin it keeps, lost to preventable causes such as discount mispricing, inventory distortion, return abuse, and uncaptured cost-to-serve. Its best-measured component, inventory distortion, costs retailers about $1.77 trillion a year worldwide (IHL Group, 2023).
Read definitionMargin Analysis
Coupon Stacking
The practice, by customers or unintentionally permitted by checkout configuration, of applying multiple discount codes to a single order, typically dropping margin below intended thresholds.
Read definitionMargin Analysis
Ghost Shrinkage
Inventory loss that does not appear in standard shrinkage accounting because it stems from data errors, reconciliation gaps, or system-of-record drift rather than physical theft or damage.

Ecommerce P&L
A structured profit and loss statement for an ecommerce business that layers ecommerce-specific cost categories — CAC, platform fees, return reserves, and fulfillment tiers — on top of standard COGS to produce a true picture of per-channel and per-SKU profitability.
Read definitionMargin Analysis
Profit Per Visitor (PPV)
A unit-economic metric defined as gross profit divided by site visitors, measuring the profit each visitor generates rather than the revenue they generate or the rate at which they convert. It is the metric that exposes A/B tests that win on conversion but lose on margin.
Read definitionMargin Analysis
CM1 vs CM2 vs CM3
CM1, CM2, and CM3 are the three layers of the ecommerce contribution margin hierarchy. CM1 is revenue minus COGS and fulfillment (the direct cost to deliver a product). CM2 subtracts variable marketing and ad spend per order (true profit after customer acquisition). CM3 subtracts allocated fixed overhead such as software, rent, and salaries.

Profit Floor
The minimum margin an order must clear after discounts, COGS, freight, fees, and FX are counted. Orders that fall below the profit floor are flagged for review or automatically held before they ship.
Read definitionProfit Governance
Profit Governance
A systematic framework for applying profitability rules to every order, so no order ships below acceptable margin thresholds without review.
Read definitionProfit Governance
Promo Abuse
When customers exploit coupon codes, referral programs, or promotional mechanics beyond their intended use, generating orders that erode margin through illegitimate discounting.
Read definitionProfit Governance
Negative Margin Order
An order where the total variable costs (COGS, shipping, discounts, payment fees) exceed the revenue collected, resulting in a net loss on the transaction.
Read definitionProfit Governance
Checkout Enforcement
Applying business rules inside checkout itself, before an order is placed, so a cart that breaks a rule cannot be completed. On Shopify this is done with discount settings and Shopify Functions such as the Cart and Checkout Validation Function. It is distinct from post-order controls that act after the order is placed and before it ships.
Read definitionProfit Governance
Propensity Modeling
Using predictive analytics to estimate the likelihood of a customer behavior -- such as returning a product, redeeming a discount, or abandoning checkout -- to inform real-time pricing and enforcement decisions.
Read definitionProfit Governance
Profit Firewall
A decision layer between order placed and order shipped that checks every order against margin policy and flags or holds the ones that fail before fulfillment, analogous to how a network firewall stops traffic that violates security rules.
Read definitionProfit Governance
Margin Governance
The institutional discipline of defining, enforcing, and auditing margin rules across every transaction, the financial-controls counterpart to revenue operations.
Read definitionProfit Governance
Checkout Governance
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.
Read definitionProfit Governance
Promo Margin Governance
Margin rules applied specifically to promotional orders, the fastest-moving and highest-risk category for margin erosion: each discounted order is checked against a margin floor, and below-floor orders are flagged or held before they ship.
Read definitionProfit Governance
Fiduciary Operating System
A unified data and policy infrastructure that gives finance teams enforceable control over how revenue, cost, and margin flow through every commerce decision.
Read definitionProfit Governance
Policy Engine
The configurable rules layer of a profit firewall, where finance teams declaratively define margin floors, discount limits, MAP rules, and other enforcement criteria.
Read definitionProfit Governance
Promotion Profitability
The net margin impact of a promotional campaign after accounting for discount depth, incremental COGS, fulfillment uplift, return rate changes, and cannibalization of full-price sales — the primary measure of whether a promotion created or destroyed value.
Read definitionProfit Governance
Safe Discount Stacking
Letting customers combine multiple discount codes on one order while making sure the resulting margin stays above a configured floor. Combination rules inside checkout decide what may stack; a per-order margin check after the order is placed catches any stack that still lands below floor before it ships.
Read definitionProfit Governance
Minimum Order Value Enforcement
The practice of enforcing order-level constraints — minimum order value (MOV), maximum quantity per line, and per-customer purchase caps — at checkout via a validation function, with the thresholds tied to margin economics rather than set as arbitrary round numbers.
