TL;DR
One-click upsells let Shopify shoppers add relevant products immediately after checkout with no friction. This moment can lift AOV by 10–20% when executed well (industry benchmark). When connected to subscription workflows using Loop Subscriptions, these upgrades become recurring revenue opportunities instead of one-time bumps. This guide covers placement strategy, optimisation, retention connections and execution.
A one-click upsell is offered after the customer’s order is placed and payment captured. The buyer clicks once to add an additional product or upgrade — no further payment or shipping info. It leverages the high intent of the moment and avoids checkout disruption.
For example, industry data shows well-targeted one-click post-purchase offers achieve 8–15% acceptance rates.
Example message:
“Add this now and save on shipping while your order is still processing.”This approach emphasizes convenience, not pressure.

Offer something that naturally complements what the customer just bought — e.g., skincare product → booster, camera → lens cleaning kit.
Tools like Rebuy help tailor recommendations based on cart content to increase accept-rate.

No new payment/shipping entry. This is technically enabled by apps like OneClickUpsell by Zipify which support true single-click post-purchase offers.

Let the customer know the offer is tied to the moment: “Add now before shipping starts,” or “Special price for today only.” This urgency must feel helpful, not pushy.

Offer one strong, clear upsell. Multiple offers cause decision fatigue and drop-off.

Since many buyers shop mobile, design copy, buttons and flow to work with one thumb interaction.
These data points show clear upside on both revenue and conversion when a one-click upsell is done well.
Most upsells stop at one transaction. The growth strategy flips when you tie upsells into subscriptions via Loop Subscriptions:
This approach converts a one-time extra into a recurring revenue lever and strengthens retention.
Q1. Do I need Shopify Plus to offer one-click upsells?
No — the post-purchase page method works on standard Shopify plans.
Q2. Will upsells annoy customers?
