Partial Refunds and Store Credit Change Your Google Ads Economics

Full Refunds vs Partial Refunds

A full refund is a complete reversal. The revenue disappears, the margin disappears, and the acquisition cost becomes pure waste. A partial refund - whether from a restocking fee, a goodwill discount, or a partial item return from a multi-item order - retains some revenue and some margin.

For a brand with £1M in monthly revenue and a 30% return rate, the difference between 100% full refunds and a 60/40 split of full-to-partial could mean £50,000+ in retained monthly margin. That margin difference should be reflected in your bidding. We see this consistently when analysing how returns destroy profit.

Store Credit Economics

Store credit is the most favourable return outcome for your advertising economics. The cash stays in your ecosystem. The customer relationship is retained. And historically, customers spend 10-20% more than the credit value when they redeem.

From a Google Ads perspective, a return that results in store credit is not a lost conversion. The original click still acquired a customer who will generate revenue. Your conversion adjustment should reflect the retained value, not treat it as a full retraction.

The Margin Recovery Ladder

Not all returns are created equal. Here's the margin recovery hierarchy from best to worst:

• • Exchange (same value or higher): ~95% margin recovery - revenue retained, often upsell opportunity
• • Store credit: ~80% margin recovery - revenue deferred but retained, with uplift at redemption
• • Partial refund (restocking fee): ~15-30% margin recovery - covers handling and depreciation
• • Full refund (product returned): ~0% margin recovery - complete loss plus reverse logistics cost
• • Full refund (product not returned): Negative margin - you lose the product AND the revenue

Understanding where your returns fall on this ladder determines how much your bidding strategy needs to adjust.

How to Treat Each in Bidding

• • Full refunds: RETRACT the conversion or RESTATE to £0
• • Partial refunds: RESTATE to net retained value
• • Store credit: RESTATE to credit value (or retain original if redemption rate > 90%)
• • Exchanges: Retain original conversion value (adjust only if net order value changed)

This granularity gives Smart Bidding a far more accurate signal than treating all returns identically. The result is better bid allocation and more accurate ROAS measurement.

Operational Levers

Your return policy is an advertising lever. Brands that default to full refunds leave margin on the table. Consider:

• • Offering store credit with a bonus (e.g., £55 credit for a £50 return) to shift customers up the recovery ladder
• • Making exchanges frictionless while adding steps to refund requests
• • Implementing restocking fees on high-return categories (fashion sizing being the obvious one)
• • Reducing return windows on categories with high time-decay depreciation

Every percentage point shifted from full refund to store credit or exchange directly improves your effective CPA. This is the post-sale margin recovery framework in action.
