How a men's supplement brand made $8,000+ in 30 days with a post-purchase upsell
With rising ad costs eating into every order, this brand added one simple offer after checkout: another bottle at 20% off, one click to accept.

Why a $40 order wasn’t enough
Before upsells, the brand was sitting at about a $40 average order. Supplements are a paid-ads game, and that doesn’t leave much room once you’ve paid to get the customer.
The CEO wanted two things: more revenue per order, and more profit per customer so ad spend actually paid off.
Pushing harder on the front end risked hurting conversion, so they installed Kaching Post-Purchase Upsell to make an offer after the customer has already bought.
Two steps after checkout
For a daily-use product, stocking up just makes sense. So the offer is simple:
- Customer completes checkout as normal
- Upsell: one more bottle at 20% off + free shipping, one click, no re-entering card details
- Follow-up: another bottle at 40% off, whether they said yes or no

The first version was live in about 15 minutes. The brand has kept tweaking the offer since, and results have grown every few months.
What happened next
In the last 30 days, about 15% of customers who saw the offer said yes, and each yes added around $32 to the order. That's $8,000+ in extra revenue in a single month.
What surprised the CEO most:
- More customers said yes than they expected
- AOV went up without hurting front-end conversion
- One-click accept made it easy, with no extra checkout steps for the customer
Because the offer only shows after the order is placed, the main sale is never at risk. Every yes is pure upside.
“Won’t this annoy my customers?”
Here's what the CEO tells merchants who think post-purchase offers are pushy or won't work in their niche:
"Post-purchase upsells don't hurt the purchase. They come after the customer completes the funnel, and they can be what makes the business profitable."

If your AOV is low and ads are eating your margin, this is one of the quickest wins you can set up.
