Let’s settle this fast.
Most people say “upsale.”
But the correct term is “upsell.”
And this tiny difference matters more than you think, because the moment you understand what an upsell really is, you can turn it into one of the highest ROI growth levers in eCommerce.
In fact, upselling can increase revenue by 10% to 30% when done properly. (That’s not hype, it’s a widely referenced benchmark from sales research.)
So if you’re a Shopify merchant, this is one of the cleanest ways to grow without spending more on ads.
Upsale or UpsellUpsell is the correct term. “Upsale” is commonly used, but it’s not the standard phrase in eCommerce marketing.
Pro tip: Use “upsell” in your site copy and SEO content, but include “upsale” as a variation in headings and FAQs to capture both searches.

People often say “upsale”, but the correct term in eCommerce marketing is “upsell.”
An upsell is when you encourage a customer to buy a higher-value version of what they’re already purchasing. The aim is to increase AOV & profitiablity.
Think: upgrade, premium, bigger size, better features.
Example:
- A customer adds a standard $29 water bottle.
- You offer the insulated stainless steel version for $39.
Or in the case of Tentree, they offer order protection as a checkout upsell.
That’s an upsell.
Upsale is basically an informal variation people use because it sounds logical (“up” + “sale”).
Some merchants use it as a synonym, but in most Shopify apps, CRO playbooks, and marketing tools, the term you’ll see is upsell.
Use upsell in your store copy and content for correct English.
Now that we’ve cleared up upsale vs upsell, here’s another mix-up that costs Shopify stores real revenue.
A lot of merchants use upsell and cross-sell like they mean the same thing.
They don’t.
One increases value by upgrading the original product.
The other increases value by adding something extra to the cart.
An upsell is when you encourage the customer to choose a higher-value version of what they’re already buying.
You’re not changing their decision.
You’re improving it.
Common upsell examples:
Example:
A customer is looking to buy a phone case, on your product page, you offer various upgraded versions of the phone case

A cross-sell is when you offer a product that pairs well with what the customer is already buying.
It’s a different item, but it makes the main purchase better.
Common cross-sell examples:
Example:
A customer buys a deodorant, you offer them body wash that pairs well with it.
Both can increase AOV, but they work best at different moments in the funnel.
If you want upsells to increase revenue without hurting conversion rate, keep it simple.
The best upsells feel helpful, not salesy.
Here are a few proven tips Shopify sellers can use right away.
Your upsell should be an upgrade, not a detour.
Good upsells include:
Upsell.com helps you increase AOV with targeted offers across the full shopping journey, from product and cart to checkout, post purchase, and beyond.
Too many offers creates decision fatigue.
One clear choice usually wins:
If your upsell needs a paragraph to explain, it’s too complex.
The fastest way to kill an upsell is to offer something unrelated.
A strong upsell should make the customer think:
“That makes sense with what I’m already buying.”
If you’re not sure where to start, begin with post-purchase upsells.
Why?
Because the purchase is already completed, so the upsell won’t interrupt checkout.
That’s why post-purchase is often the easiest place to increase AOV without adding friction.
Here’s the truth most Shopify stores learn the hard way:
A great upsell can fail just because it appears at the wrong time.
That’s why “where” you place your upsell is just as important as “what” you’re selling.
Below are the four main upsell locations on Shopify, plus when to use each one.
Product page upsells work because the customer is still exploring.
They’re open to options.
That makes this the perfect spot for:
Example: Customer is viewing the standard flowers bouquet, you pre-select the deluxe bundle (and test adding 'most popular' too)
Best practice:
Keep the upsell close to the main product. Same goal, same category, same intent.
Cart upsells are strongest when they’re:
This is where “quick wins” shine, such as:
Example:
Customer has $39 in cart.
You show:
Watch out:
The cart is also a major exit point, so don’t overload it with choices.
One offer is usually enough.
Checkout is a sensitive zone.
Customers are in “finish the purchase” mode.
So if you place upsells here, they need to be:
This location works best for:
Example:
Customer is checking out with standard shipping.
You offer:
Best practice:
Keep it simple. If it creates friction, it costs you conversion.
This is where most Shopify brands should start.
Why?
Because the customer already bought.
So you’re not competing with the decision to purchase.
You’re simply offering an upgrade or add-on while buying intent is still high.
Post-purchase upsells work best for:
Example:
Customer buys a skincare cleanser.
On the thank you page you offer:
Why it converts:
No additional checkout friction. Just one click.
If you want the simplest path to more revenue:
And if you’re unsure where to begin, start with post-purchase. It’s usually the highest ROI and the lowest risk.
So, upsale or upsell, which one is correct?
Upsell is the standard term.
