Prerequisites and Data Requirements

What You'll Need Before Starting

Before diving into transaction source analysis, ensure you have the following:

Understanding Square Transaction Sources

Square categorizes transactions by source based on how the payment was captured:

Data Quality Checklist

Before analysis, verify your data meets these quality standards:

✓ Complete date range without gaps
✓ All transactions include source information
✓ Device IDs are consistently formatted
✓ Amount fields contain numeric values
✓ No duplicate transaction IDs
✓ Refunds are properly categorized

Step 1: Export Your Square Transaction Data

The first step in transaction source analysis is exporting your raw data from Square. This process is straightforward but requires attention to detail to ensure you capture all necessary fields.

Accessing the Transaction Report

  1. Log into your Square Dashboard at squareup.com
  2. Navigate to Reports in the left sidebar
  3. Select Transactions from the report types
  4. Choose your date range (recommended: last 90 days for comprehensive analysis)

Configuring Export Settings

To ensure your export contains all necessary data for source analysis:

  1. Click the Export button in the top right corner
  2. Select CSV as the file format
  3. Ensure these columns are included in your export:
    • Date/Time
    • Transaction ID
    • Source
    • Device Name
    • Gross Sales
    • Net Sales
    • Processing Fees
    • Payment Method
  4. Click Download Report

Expected Output

Your exported CSV file should look similar to this:

Date,Transaction ID,Source,Device Name,Gross Sales,Net Sales,Processing Fees
2024-01-15 14:23:11,ABC123XYZ,Square Terminal,Terminal 1,$45.00,$43.76,$1.24
2024-01-15 14:45:22,DEF456UVW,Square Online,Online Store,$89.99,$87.38,$2.61
2024-01-15 15:12:33,GHI789RST,Square Reader,Mobile Reader A,$23.50,$22.86,$0.64

The export typically takes 30-60 seconds for datasets containing thousands of transactions. For very large datasets (100,000+ transactions), the export may take several minutes and Square will email you a download link.

Step 2: Prepare Your Data for Analysis

Data preparation is crucial for accurate analysis. Even clean Square exports may require minor adjustments to ensure compatibility with analytical tools.

Opening and Inspecting Your Data

  1. Open the downloaded CSV file in a spreadsheet application (Excel, Google Sheets, or similar)
  2. Verify that all rows contain data (look for any blank cells in critical columns)
  3. Check that monetary values are formatted consistently (e.g., all have two decimal places)

Common Data Cleaning Tasks

Handling Refunds: Decide whether to include or exclude refunds from your analysis. For profitability analysis, you'll typically want to include refunds as negative transactions to get an accurate net revenue picture.

# If excluding refunds, filter for:
Gross Sales > 0

# If including refunds, keep all rows but note:
# Negative values represent refunded amounts

Standardizing Source Names: Sometimes Square may use slight variations in source names. Ensure consistency:

Square Online Store → Square Online
Square Online Checkout → Square Online
Square for Retail POS → Square Terminal

Handling Missing Device Names: Some transactions may not have a specific device assigned. These are typically online or invoice transactions:

If Device Name is blank and Source = "Square Online":
    Device Name = "Online - Not Applicable"

Data Validation Checklist

Before proceeding to analysis, confirm:
