Shopify Seller Cost Checklist
Use this checklist of Shopify costs to avoid underpricing products or underestimating profit pressure from product costs, shipping, fulfillment, apps, payment fees, advertising, refunds, and overhead.
What costs should Shopify sellers track?
Shopify sellers should track both order-level costs and store-level costs. Order-level costs happen each time a customer buys something. Store-level costs exist even before an order is placed, such as the Shopify plan, apps, software, bookkeeping, subscriptions, and other overhead.
The most common mistake is judging profit from revenue alone. A store can grow sales while margin gets worse if shipping, ads, discounts, refunds, or app costs rise faster than profit.
Order-level Shopify costs
Product cost, supplier cost, production cost, or landed inventory cost.
Inbound freight, duties, tariffs, or shipping paid to receive inventory.
Shipping labels, carrier surcharges, insurance, and delivery upgrades.
Packaging, boxes, mailers, tape, labels, inserts, and protective material.
Payment processing percentage and fixed transaction fee.
Fulfillment, pick-pack, warehouse, or handling cost.
Ad cost, affiliate commission, influencer cost, or acquisition cost per order.
Refund allowance, replacement cost, return shipping, and chargeback risk.
Store-level Shopify costs
Monthly Shopify plan cost.
Paid apps, subscriptions, upsell tools, review tools, and subscription apps.
Themes, page builders, design tools, and creative software.
Email marketing, SMS, CRM, analytics, heatmaps, and automation tools.
Bookkeeping, tax software, professional services, and accounting support.
Contractors, customer support, virtual assistants, designers, or developers.
Domain, email, hosting-adjacent tools, and brand assets.
Inventory storage, warehouse minimums, and slow-moving stock costs.

Common Shopify cost mistakes
Pricing products from supplier cost only instead of total selling cost.
Forgetting payment fees, packaging, shipping surcharges, and fulfillment labor.
Ignoring app costs because each app looks small on its own.
Treating ad spend as optional even when sales depend on paid traffic.
Not assigning refunds, returns, chargebacks, and replacements to product profit.
Using store-wide averages when different products have very different margins.
