Google Ads conversion values frequently don’t match NetSuite transaction amounts, creating ROI calculation discrepancies that undermine marketing investment decisions. Estimated values differ from actual amounts, and currency conversions create artificial mismatches.

Here’s how integrated data analysis identifies and resolves value discrepancies for accurate marketing ROI measurement.

Actual revenue data provides true ROI calculation accuracy

Coefficient enables comprehensive value reconciliation through integrated data analysis. While Google Ads uses estimated conversion values, systematic correlation with actual NetSuite transaction amounts provides reliable marketing ROI calculations based on real business outcomes.

How to make it work

Step 1. Import both conversion data and actual transaction amounts.

Pull Google Ads conversion data with reported values and NetSuite transaction records with actual amounts to systematically identify discrepancies. This reveals the scope of value mismatches in your attribution.

Step 2. Aggregate customer-level revenue for accurate attribution.

Use Records & Lists to pull all NetSuite transactions per customer, then correlate with Google Ads conversion events to calculate true customer lifetime value attribution rather than single conversion estimates.

Step 3. Account for multi-transaction customer relationships.

Import NetSuite customer transaction history to capture repeat purchases and upsells that Google Ads conversion tracking may not include in initial conversion values. This provides complete revenue attribution.

Step 4. Standardize currency formatting across datasets.

Pull both datasets with consistent currency formatting to eliminate conversion rate discrepancies that create artificial value mismatches between Google Ads and NetSuite reporting.

Step 5. Analyze revenue components for value differences.

Import NetSuite transaction data with detailed line items including subtotal, tax, shipping, and discounts to understand why actual amounts differ from Google Ads conversion values.

Step 6. Set up automated value reconciliation monitoring.

Schedule regular data refreshes to continuously monitor conversion value accuracy and flag significant discrepancies for investigation, maintaining ROI calculation reliability.

Step 7. Calculate ROI using actual NetSuite transaction amounts.

Use actual NetSuite revenue data rather than Google Ads conversion values for marketing spend analysis and campaign optimization decisions. This ensures ROI calculations reflect real business outcomes.
