What Is an Upsell Funnel? Upsell and Downsell Paths

How an Upsell Funnel Branches

One upsell asks one question. A funnel also decides what happens after the answer.

It starts with a trigger, like a certain product or an order over a set amount. Then comes a first offer. If the buyer says yes, a second offer that builds on the first can follow. A no can lead to a downsell instead: something smaller or cheaper than what they turned down. After the last step comes the thank you page.

The buyer's already picked you and paid. The funnel tries to grow that order without paying for new traffic.

Unlike a sales funnel, which covers the whole path from first visit to purchase, an upsell funnel starts after the buyer has decided. Its only job is a bigger order.

Where Upsell Funnels Run on Shopify

Shopify lets apps add a page between payment and the thank you page. Funnel apps put their steps there. Buyers usually don't retype their payment details, so each yes can take one click. Since the main order is already placed, a no can't undo it.

Setting one up? Our guide to creating a post-purchase upsell funnel on Shopify goes step by step.

A Boot Store Funnel, Worked Out

The order: A buyer pays $120 for hiking boots.

Step 1, the upsell: A $25 waterproofing kit. It costs you $8, so each yes earns $17 gross profit (price minus product cost, before fees).

Step 2 after a yes: Wool hiking socks for $15 that cost you $5, so $10 per yes.

Step 2 after a no, the downsell: A $12 waterproofing spray that costs you $4. That's $8 per yes.

Per 100 buyers: Say 6 take the kit and 1 of those 6 adds the socks. Of the 94 who said no, 3 take the spray. These rates are only for illustration.

Extra sales: (6 × $25) + (1 × $15) + (3 × $12) = $150 + $15 + $36 = $201
Extra gross profit: (6 × $17) + (1 × $10) + (3 × $8) = $102 + $10 + $24 = $136
Average order value: ($12,000 + $201) ÷ 100 = $122.01, up from $120

The downsell makes the least per yes, but it's the only step that reaches the 94 who said no.

The kit is about 21% of the order ($25 ÷ $120), so it stays under the 25% rule in our post-purchase upsell guide. At 52% cheaper than the kit, the spray sits inside that guide's 40-60% downsell range.

When a Funnel Costs More Than It Earns

Too many screens. Every step pushes back the thank you page, and buyers may wonder if the order went through.
A downsell that teaches "no". If it's the same item for less, repeat buyers can learn that turning down the first offer gets them a better price.
Steps that don't connect. Socks after boots makes sense. A candle after boots just feels like a random ad.
Discounts on thin margins. Slash the price on a low-margin item and every yes can cost you money.

Does a Longer Funnel Earn More?

Each step can look like one more free shot at a yes. But every step reaches fewer people. In the boot example, only 6 buyers saw the socks offer.

Our Shopify upsell apps compared page draws on 250 stores and 66M offers from January to June 2026. Across 20M sessions, visitors accepted the first offer they saw 5% of the time. The second got 8%, the third 6% and the fourth 1%. Downsells got 3%.

That dataset covers offers in every placement, not only after-payment funnels. People who reach a third or fourth offer aren't a random group, and this wasn't a controlled test. So the data doesn't prove a second offer sells better. It does show that fourth offers were rarely taken. Judge a funnel by profit per order, not by offer count.

How Growth Suite Handles Upsell Funnels

Growth Suite, our Shopify app, has Post-Purchase Upsell Funnels. Buyers take its offers after checkout with one click, without entering payment details again. You can trigger a funnel by what's in the order, the order total or how many items were bought. An algorithm helps pick the product for each offer.
