What it does

Shopify Admin Profit Margin Calculator is an agent skill from 40RTY-ai/shopify-admin-skills. Read-only: calculates true net profit per order and per product by factoring in COGS, shipping costs, transaction fees, discounts, refunds, and taxes.

Its SKILL.md is about 2k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts. Compatibility notes: Claude Code, Cursor, Codex, Gemini CLI

It works with Shopify. The repository describes itself as: Community-maintained AI agent skills for operating Shopify stores — workflows, optimization, reports and more. The licence is MIT.

Example prompts

  • “/shopify-admin-profit-margin-calculator”

Requirements

  • Compatibility (from SKILL.md): Claude Code, Cursor, Codex, Gemini CLI

Workflow steps

5 steps, taken from the first numbered list in SKILL.md.

  1. OPERATION: orders — query
  2. OPERATION: inventoryItems — query
  3. For each order, calculate
  4. If group_by: product or variant, aggregate profits by product/variant across all orders
  5. OPERATION: productVariants — query (enrichment)

What it can do on your machine

Read from SKILL.md and the folder at commit 6765cb4. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • shopify

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

  • Compatibility

    Claude Code, Cursor, Codex, Gemini CLI

    From compatibility in the SKILL.md frontmatter.

Context cost

Shopify Admin Profit Margin Calculator loads about 2k tokens when it runs. Until then it costs about 47 tokens; SKILL.md has 474 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~47
When it runs · the whole SKILL.md, loaded when a task matches
~2k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Purpose

Calculates true net profit and margin at both order-level and product-level granularity. Unlike basic revenue reports, this skill deducts all cost components — COGS (from inventoryItem.unitCost), shipping costs, transaction/payment processing fees, applied discounts, refund amounts, and duties/taxes — to surface actual margin percentages. Read-only — no mutations.

Prerequisites

  • Authenticated Shopify CLI session: shopify store auth --store <domain> --scopes read_orders,read_products,read_inventory
  • API scopes: read_orders, read_products, read_inventory
  • For accurate results, products should have inventoryItem.unitCost populated

Parameters

ParameterTypeRequiredDefaultDescription
storestringyes—Store domain (e.g., mystore.myshopify.com)
days_backintegerno30Lookback window for orders
group_bystringnoorderGrouping: order, product, or variant
min_ordersintegerno1Minimum orders for a product to appear (product/variant mode)
include_refundedbooleannotrueInclude fully refunded orders in calculation
formatstringnohumanOutput format: human or json

Safety

ℹ️ Read-only skill — no mutations are executed. Safe to run at any time.

Workflow Steps

  1. OPERATION: orders — query Inputs: query: "created_at:>='<NOW - days_back days>'", first: 250, select id, name, createdAt, totalPriceSet, subtotalPriceSet, totalShippingPriceSet, totalTaxSet, totalDiscountsSet, currentTotalPriceSet, displayFinancialStatus, refunds { totalRefundedSet }, lineItems { variant { id, inventoryItem { id, unitCost { amount, currencyCode } } }, quantity, originalTotalSet, discountedTotalSet }, pagination cursor Expected output: All orders in window with full cost breakdown

  2. OPERATION: inventoryItems — query Inputs: Batch of inventoryItemIds from line item variants for any missing unitCost data Expected output: Unit cost for each inventory item

  3. For each order, calculate:

    • Revenue = currentTotalPriceSet.shopMoney.amount
    • COGS = Σ(lineItem.quantity × variant.inventoryItem.unitCost)
    • Shipping Cost = totalShippingPriceSet.shopMoney.amount (merchant-paid portion estimate)
    • Discounts = totalDiscountsSet.shopMoney.amount
    • Transaction Fee = estimated at 2.9% + $0.30 of total (configurable)
    • Refunds = Σ(refunds.totalRefundedSet.shopMoney.amount)
    • Net Profit = Revenue - COGS - Shipping - Transaction Fee - Refunds
    • Margin % = (Net Profit / Revenue) × 100

  4. If group_by: product or variant, aggregate profits by product/variant across all orders

  5. OPERATION: productVariants — query (enrichment) Inputs: Variant IDs from profitable/unprofitable items for product title context Expected output: Product titles, SKUs for display

Error Handling

ErrorCauseRecovery
THROTTLEDAPI rate limit exceededWait 2 seconds, retry up to 3 times
Missing unitCostProduct COGS not setFlag as "unknown COGS" — include in report but exclude from margin calc
Refunded ordersFully refundedInclude with $0 net revenue if include_refunded: true

Best Practices

  • Populate inventoryItem.unitCost on all products for accurate COGS. Without it, margins cannot be calculated.
  • Adjust transaction fee estimate based on your payment processor (default 2.9% + $0.30 matches Shopify Payments US).
  • Use group_by: product to identify which products are margin-positive vs. margin-negative.
  • Cross-reference with stock-velocity-report to find fast-selling but low-margin items that may need repricing.
  • Use results with bulk-price-adjustment to increase prices on margin-negative products.
