How to Track Dropshipping Expenses in Google Sheets

Tracking expenses is critical for dropshipping profitability. This guide shows you how to set up a complete expense tracking system in Google Sheets with automated bank sync, category tracking, and profit margin calculations.

Key Dropshipping Expense Categories

A profitable dropshipping business tracks these expense categories:

• Cost of Goods Sold (COGS) - Product costs from suppliers (AliExpress, Alibaba, etc.)
• Advertising Costs - Facebook Ads, Google Ads, TikTok Ads, influencer marketing
• Platform Fees - Shopify subscription, payment processing fees (Stripe, PayPal)
• Software & Tools - Oberlo, DSers, email marketing, analytics tools
• Shipping Costs - Any shipping fees not covered by customer charges
• Returns & Refunds - Product returns, customer refunds, chargebacks
• Other Business Expenses - Virtual assistant, graphic design, domain registration

Step 1: Set Up Your Expense Tracking Sheet

Create a Google Sheet with these columns:

Step 2: Automate Transaction Imports with SheetLink

Instead of manually entering every transaction, use SheetLink to automatically sync bank and credit card transactions to your Google Sheet:

1. Install SheetLink - Add the Chrome extension from the Chrome Web Store
2. Connect your bank accounts - Use Plaid to securely connect business checking, credit cards, and PayPal
3. Choose your expense tracking sheet - SheetLink will write transactions directly to your Google Sheet
4. Click sync - All business expenses automatically appear in your sheet

Step 3: Categorize Your Expenses

After transactions are imported, categorize them for tax purposes and profitability analysis:

• Use data validation - Create a dropdown list in the Category column with your standard categories (COGS, Advertising, Platform Fees, etc.)
• Set up auto-categorization - Use simple formulas to automatically categorize common vendors:

  =IF(ISNUMBER(SEARCH("Facebook", B2)), "Advertising",
  IF(ISNUMBER(SEARCH("Shopify", B2)), "Platform Fees", "Other"))

• Review monthly - Spot-check auto-categorized transactions to ensure accuracy

Step 4: Calculate Profit Margins

The real power comes from calculating your true profit margins. Create a summary section:

Step 5: Track Key Metrics

Beyond basic expense tracking, monitor these critical dropshipping metrics:

• Customer Acquisition Cost (CAC) - Ad spend ÷ Number of customers
• Return on Ad Spend (ROAS) - Revenue ÷ Ad spend (target 2.5x or higher)
• Average Order Value (AOV) - Total revenue ÷ Number of orders
• Profit per Order - (Revenue - COGS - Ads - Fees) ÷ Number of orders
• Operating Expense Ratio - Operating expenses ÷ Revenue (keep under 20%)

Tax Preparation Tips

Proper expense tracking makes tax season painless:

• Separate business and personal - Use dedicated business bank accounts and credit cards
• Keep receipts - Store digital copies in Google Drive, linked to transactions
• Track quarterly - Review P&L each quarter to estimate tax liability
• Work with an accountant - Share your expense sheet directly with your CPA
• Understand deductions - Most dropshipping expenses are deductible (home office, software, ads, etc.)
