How to Increase Ecommerce Sales with Bundling & Upsells

Most ecommerce owners focus on ads, SEO, or getting more traffic. Those things matter, but they cost money and take time. A faster, cheaper path is to sell more to the people who are already buying from you. That’s where bundling and upselling come in. If you’re wondering how to increase ecommerce sales, this is the place to look first.

Instead of pushing harder to get new customers, you give existing customers better choices. You make buying easier. You increase the average order value. And you do it in a way that doesn’t feel like pressure.

Let’s break it down into 10 real, workable points.

1. Bundle Products That Naturally Fit Together

If you’re serious about figuring out how to increase ecommerce sales, start with obvious bundles. No one wants random items forced together. The trick is to think about what people usually buy next.

A phone with a case and screen protector.
A gym outfit with leggings and a sports bra.
Coffee beans with a grinder and a storage jar.

When the items go together, the bundle feels natural. Customers don’t feel like they’re spending more, they feel like they’re solving a bigger problem in one go. That’s what makes bundling effective.

2. Give a Small but Noticeable Discount on Bundles

Bundling works better when there’s a small saving. It doesn’t have to be huge. Even 5–10% is enough to nudge people.

Say you sell a cleanser for $20, toner for $20, and moisturizer for $25. Separately, that’s $65. Offer the set for $55. Customers feel like they’re saving, and you’ve sold three products instead of one.

This is one of the cleanest answers to how to increase ecommerce sales without more traffic. You’re not lowering your margins much, but you’re increasing order value.

3. Upsell with Better Versions

Upselling is simple: show customers a slightly better version of what they already want. Most people don’t know the difference until you explain it.

Someone picks a $40 backpack. Offer a $60 version with more space and stronger zippers. Someone picks basic earbuds. Offer premium ones with noise cancellation for $30 more.

Not everyone will upgrade. But even if 10–15% do, your revenue goes up. That’s a straight path on how to increase ecommerce sales without feeling fake.

4. Place “Frequently Bought Together” Suggestions

People copy what others buy. It’s how Amazon dominates. If someone buys a laptop, they see a mouse and a bag right below. If someone buys a dog bed, they see chew toys and bowls.

You don’t need a big system. Most ecommerce platforms let you set this up. The point is simple: make related items visible, not hidden. This alone can answer your question of how to increase ecommerce sales, because customers naturally add more when they see what “usually” goes with their choice.

5. Use Popups the Right Way

Most popups are junk. But when used carefully, they can work for upselling. The key is timing.

Don’t hit people with a popup as soon as they land. That’s annoying. Instead, use exit-intent or checkout popups. For example:

Someone adds a shampoo to cart. Popup: “Want the conditioner for 20% off?”
Someone’s about to leave the checkout. Popup: “Add gift wrap for $3?”

That small nudge feels helpful, not spammy. Done right, this is another solid example of how to increase ecommerce sales through bundling and upselling.

6. Don’t Hide the Upsells

A lot of stores make upsells hard to find. They’re buried in tabs or hidden behind links. If you want upsells to work, put them in the customer’s face without being annoying.

Show bundle options right on the product page.
Place add-on suggestions in the cart page before checkout.
Show pictures of the bundle, not just text.

This makes it clear and effortless. People don’t want to think too much. This simplicity is a real-world way of how to increase ecommerce sales.

7. Keep Control in the Customer’s Hands

Nobody likes being tricked. Auto-adding products to carts or forcing bundles is a bad move. Customers should feel like they chose it, not like you forced it.

One good tactic is a checkbox: “Add this for 15% off.” It’s optional, visible, and fair. The psychology is strong: people like choices, not traps.

Respecting customer control is another part of how to increase ecommerce sales that keeps buyers coming back instead of leaving angry.

8. Test Bundle Sizes and Styles

Not every customer wants the same thing. Some like small add-ons, others want complete sets. The only way to know is to test.

Examples:

Buy 2 get 10% off.
Buy 3 get 15% off.
Family pack of 5 with 20% off.

Run all three and see which sells. Sometimes small bundles win because customers don’t want to commit big. Sometimes bigger sets work better. Tracking this is practical how to increase ecommerce sales work.

If buyers mention bundles or upsells in reviews, highlight those. Example:

“Got the camera kit with tripod and bag. Totally worth it.”

This kind of review builds trust. It’s not you saying it — it’s another buyer. Customers are more likely to buy the larger option if they see others already did.

This is one of the overlooked answers to how to increase ecommerce sales. You don’t need to be convinced. You just need to show proof.

10. Keep Tracking and Adjusting

Bundling and upselling aren’t one-time setups. You need to watch which bundles sell, which upsells get ignored, and whether discounts are working.

Maybe people love the “coffee machine + beans” bundle but ignore the “coffee machine + mug” one. Maybe they upgrade when the upsell is $20 higher but not when it’s $50 higher.

You learn by testing, not guessing. This is the most down-to-earth way of how to increase ecommerce sales. Keep adjusting until the numbers show what customers actually want.

Conclusion

Bundling and upselling work best when they feel natural, fair, and useful. If you respect your customer’s time and choices, you’ll sell more without forcing it. That’s the most honest way of how to increase ecommerce sales.
