Automatically Tracking Costs, Shipping, and Marketplace Fees
Managing an ecommerce business across multiple platforms involves more than just sales—it requires precise financial tracking. Automating the tracking of product costs, shipping, and marketplace fees is essential to maintain profit margins, avoid errors, and make data-driven decisions. This guide outlines how to set up automated systems for accurate and efficient financial management.
Why Automated Cost Tracking Matters
- Accurate Profit Margins: Know your true profits after all deductions
- Time Efficiency: Eliminate manual calculations and spreadsheet entry
- Data-Driven Decisions: Optimize pricing and product strategies using real cost insights
- Tax and Accounting Compliance: Maintain audit-ready records without manual reconciliation
Key Cost Components to Track
1. Product Cost (COGS)
- The wholesale or supplier price per unit
- May vary by batch or SKU
2. Shipping Costs
- Postage/carrier fees (e.g., USPS, UPS)
- May include packaging materials
- Different for standard, expedited, and international shipments
3. Marketplace Fees
- Amazon: Referral fees (usually 8–15%), FBA fees (if applicable)
- Walmart: Referral fees, shipping chargebacks
- eBay: Final value fee, PayPal/processing fees
- Shopify: Transaction fees, app subscription costs

Setting Up Automated Tracking
1. Connect Your Data Sources
- Supplier systems (e.g., spreadsheets, B2B portals)
- Marketplace APIs (Amazon MWS/SP-API, Walmart API, eBay API)
- Shipping platforms (ShipStation, EasyPost, etc.)
2. Map Costs to Orders
Use EcomBiz.AI or your automation tool to match:
- Order ID → Product SKU → Cost of Goods
- Shipping label ID → Carrier → Shipping Cost
- Marketplace transaction ID → Commission & Fee
3. Set Rules for Custom Adjustments
- Add fixed overhead per unit (e.g., $1.00 handling)
- Apply tiered shipping zones
- Track bundled items by component cost
Avoid These Mistakes
- Manual entry without validation: Increases error rates
- Ignoring shipping surcharges: Dimensional weight or remote area charges can erode margins
- Missing SKU-level profitability: Not all products have the same margin—track individually
