Attribution When Gift Cards Pay: Who Gets Credit for the Sale?
A gift card splits one purchase into two events months apart. How to attribute the sale and the redemption without double counting revenue.
A gift card creates two transactions: the card purchase, often in December, and the redemption, often in January, by a different person. Blend them carelessly and revenue doubles on paper, acquisition channels claim sales they never influenced, and January looks like a miracle month that no campaign caused.
This guide sets out a clean treatment: card sales as their own line, redemptions attributed to the redemption journey with the card flagged, and the reports that keep both halves honest.
Separate the card sale from the merchandise sale
Record gift card sales as stored value sold, not as merchandise revenue. The merchandise revenue arrives at redemption, when goods actually leave. Reports that count both the card sale and the full basket at redemption inflate the season by exactly the card amount, every year, in the same direction.
Channel credit for the card purchase itself is still useful: which campaigns sell cards is a real question in December. Just keep it in the stored value report, so card selling performance never masquerades as product demand.
Attribute the redemption journey on its own terms
At redemption, attribute the basket to the recipients journey: the search, email, or visit that brought them in, with a flag that payment included a gift card. That flag matters because redemption baskets behave differently: they skew to treating oneself, trying new categories, and spending slightly over the card value.
The over card spend is genuinely new revenue influenced by the redemption visit. Separating card funded and card plus cash portions lets you value redemption traffic honestly instead of treating the whole basket as either free or fully earned.
Watch the breakage and expiry assumptions
Unredeemed balances and expiry rules change the economics, and they vary by region and by card terms. Finance and marketing should agree the assumption used in reports, state it, and keep it stable across a season. An attribution model that silently changes its breakage assumption manufactures trends.
Never let breakage flatter a channel. Unredeemed value is not campaign performance, however it is recognised in accounts. Keep it out of channel reporting entirely, in its own line, reviewed by finance.
Build the January report before January
Agree the treatment in November: card sales line, redemption attribution rules, the over value split, and the breakage assumption, written down with owners. January arguments about whose campaign caused the redemption peak happen every year in teams that skip this hour.
With the rules set, January becomes readable: redemption driven revenue is visible, acquisition for card sales is credited in December where it belongs, and no channel gets to claim the same money twice.

Frequently asked questions
Why do gift cards distort attribution?
One purchase becomes two events, a card sale and a later redemption by a different person. Counting both as merchandise revenue double counts, and crediting the redemption basket to December acquisition claims influence that never happened. The split needs explicit rules.
How should gift card sales be reported?
As stored value sold, in their own line, with channel credit for card selling campaigns kept in that report. Merchandise revenue belongs at redemption, when goods are actually bought and shipped.
How should a redemption basket be attributed?
To the recipients own journey that brought them to redeem, flagged as gift card funded, with any spend over the card value separated. Redemption shoppers behave differently, and the over value portion is the part the redemption visit genuinely influenced.
What is breakage and why keep it out of channel reports?
Breakage is card value never redeemed. Its recognition is an accounting matter with agreed assumptions, not campaign performance. It should sit in its own finance reviewed line so it never flatters a channel or a season.
