# One-Click Upsells Overview

Increase AOV with post-purchase upsell offers that customers accept with one tap

Last updated: 2025-01-16

**One-Click Upsells** are post-purchase offers that appear immediately after a customer completes checkout. Because the customer has already entered payment information, they can accept additional offers with a single click—no re-entering payment details required.

##### Why Post-Purchase?

Post-purchase upsells have significantly higher acceptance rates than pre-checkout offers because they don't interrupt the buying decision. The customer has already committed to purchasing, making them more receptive to related offers.

## How It Works

1.  **Customer completes checkout** — Standard Shopify checkout flow
2.  **Upsell page appears** — Before the thank you page, customer sees your offer
3.  **One-click acceptance** — Customer taps "Add to Order" to accept
4.  **Order updated instantly** — Upsell item added to the original order
5.  **Thank you page** — Customer sees confirmation with all items

## Upsell Types

CheckoutOS supports several types of post-purchase offers:

#### Available Upsell Types

*   Single product upsell — Offer one specific product
*   Product collection upsell — Let customer choose from multiple options
*   Bundle upsell — Offer a discounted bundle of products
*   Subscription upsell — Convert the purchase to a subscription
*   Downsell — Show alternative if customer declines main offer

## Targeting Options

Control when upsells appear with flexible targeting rules:

*   **Cart contents** — Show specific offers based on products in cart
*   **Order value** — Target customers based on cart total
*   **Customer tags** — Show different offers to VIPs or new customers
*   **Product collections** — Trigger offers when buying from specific collections
*   **Geographic location** — Customize offers by country or region

## Best Practices

##### Optimization Tips

*   **Keep offers relevant** — Upsells should complement the original purchase
*   **Use compelling discounts** — 15-25% off works well for most products
*   **Test different products** — What you think will sell may not be the winner
*   **Limit options** — One clear offer converts better than multiple choices
*   **Mobile-first design** — Most checkout traffic is mobile

## Performance Metrics

Track your upsell performance in the CheckoutOS analytics dashboard:

*   **View rate** — Percentage of checkouts that see the upsell
*   **Acceptance rate** — Percentage of views that accept the offer
*   **Revenue generated** — Total additional revenue from upsells
*   **AOV lift** — Increase in average order value
*   **ROI** — Return on your CheckoutOS investment
