An upsell offers a higher-value version of what the buyer is already choosing, such as the annual plan instead of the monthly one. A cross-sell offers a different product that goes with it, such as a template pack with a course. The test is simple: if the new item replaces the first choice, it is an upsell. If it is added next to it, it is a cross-sell.
Both can appear on a product page, in a checkout or after payment. What changes is the question you are asking the buyer.
The difference at a glance
| Upsell | Cross-sell | |
|---|---|---|
| The offer | A bigger, better or longer version of the same thing | A different product that complements it |
| Replaces the first choice? | Yes, usually | No, it is added |
| Example | $97 course, offered the $297 edition with coaching calls | $97 course, offered a $19 workbook |
| Buyer’s question | “Do I want the better version?” | “Do I also want this?” |
| Usually needs | A short explanation of what the upgrade adds | A line or two, as it is a small item |
The words are used loosely. A “bundle upsell” that adds items to the first purchase behaves like a cross-sell. Don’t spend time on the label; decide what you are offering and whether it fits the buyer.
Upsell examples
- Monthly to annual. A subscriber choosing the monthly plan sees the yearly price with the saving in dollars.
- Single licence to team licence. A template buyer is offered the same template with team seats.
- Course to course with coaching. The same course, with live calls included.
- Starter to growth plan. Shown at the point a buyer hits a limit, with the price difference stated.
Cross-sell examples
- Course and workbook. A printable workbook that goes with the course.
- Software and setup session. A one-hour onboarding call offered next to a plan.
- Event ticket and recording. Someone buying a ticket is offered the replay.
- Template and font pack. A second digital product that suits the first.
Where each one fits in a checkout
A checkout has three moments to make an offer, and each suits a different kind of offer.
- On the checkout page, before payment. Best for small cross-sells that need no explanation. This is the order bump: a tick box that adds a companion item to the same order.
- Straight after payment. Best for upsells, and for larger cross-sells. The buyer has agreed to pay, so the question is only whether more is worth having. They should not have to re-enter card details.
- When a customer is about to cancel. A save offer gives a cancelling subscriber one relevant alternative, such as a cheaper plan or a pause.

Choosing between them
Ask what the buyer is trying to do.
- They are comparing tiers or plans. Make an upsell. They are already thinking about “how much do I need?”.
- They have chosen and are ready to pay. Offer a small cross-sell. Anything that needs a paragraph will slow them down.
- They have just paid. Offer one thing, either the better version or the obvious companion. Not both.
- Your product has no higher-value edition or upgrade. Offer a relevant companion product as a cross-sell.
Keep the offer relevant to the first purchase. A buyer of a spreadsheet template might want a team licence or a guide on using it; they don’t want a random product from your catalogue.
What to measure
- Take rate: the share of buyers who accept the offer.
- Revenue per buyer: total revenue from these buyers, offers included, divided by the number of buyers. This is better than average order value, because post-purchase offers can add orders and change that average.
- Refunds and support tickets on orders that include the offer. A rise means the offer is confusing or pushy.
- Completion of the first purchase. An offer placed after payment should not change it. One placed before payment can.
Change one thing at a time and compare the same days of the week.
Setting both up in Plandalf
Plandalf’s checkouts support order bumps and upsells on one-time, package, tiered, volume and subscription prices, and run them as steps in a multi-page flow: plan selection, details, payment, an offer page and confirmation. A sensible first setup:
- Build the checkout for your main product.
- Add one order bump for a small companion item (your cross-sell).
- Add one post-purchase step with the better version of the product (your upsell).
- Test a purchase with each offer accepted and declined, and check the totals, the invoice lines and any follow-up email.
If you run a deadline on the offer, Promos keep the countdown and price in step. Stripe or PayPal processes the payment. Plandalf is $49 a month or $490 a year with a 14-day free trial; see the pricing section for current terms.
FAQ
What is the difference between an upsell and a cross-sell?
An upsell offers a higher-value version of what the buyer is already choosing. A cross-sell offers a different product that complements it. An upsell usually replaces the first choice; a cross-sell is added to it.
Is an order bump an upsell or a cross-sell?
Usually a cross-sell. An order bump is a small extra item ticked on the checkout page, added to the same order. An upgrade to a larger version of the main product is an upsell.
Which earns more, an upsell or a cross-sell?
It depends on your prices and your buyers, and there is no general answer. Test one against the other and compare revenue per buyer, not just take rate.
Can I use both in one checkout?
Yes. Start with one small cross-sell before payment and one upsell after it. Add more only if take rates hold and refunds don’t rise.
What is a downsell?
A downsell is a cheaper alternative offered when a buyer declines an upsell or tries to cancel. A save offer for a cancelling subscriber is a common example.
