Checkbox Upsell: Add a Gift Box or Warranty in One Tick

Here's something most store owners never set up — and it costs them add-on sales every single day. A shopper is on your product page, ready to buy, and right there is the perfect moment to ask: "Want to add a gift box?" But there's nowhere to ask, so the question never gets asked, and the add-on never gets sold.

Checkbox Upsell puts a simple tick-box right under your Add to cart button. One tick, and a matching product drops into the cart alongside the main item — no extra page, no pop-up, no hunting around the store.

It's the before-purchase partner to the checkout upsell, which makes its offer on the thank-you page instead. And for products people love to make their own, you can pair it with a build-your-own kit so shoppers add the matching pieces themselves.

What your customer sees

Under the Add to cart button on the product page, a small checkbox offers the add-on you've chosen — say, "Add a gift box (+$6)" or "Add a 2-year warranty." When the shopper ticks it and adds to cart, both items go in together, the add-on at its normal price.

• Shown right where shoppers decide — under Add to cart, not buried elsewhere.
• One tick adds it — no extra clicks, no second decision.
• You see what's working — which add-ons get accepted, and on which products.

Where it earns its keep

Gift boxes, gift wrap, warranties, care kits, matching accessories, a "make it a set" upgrade — anything that naturally rides along with the main product. It's the kind of small, easy yes that adds up across hundreds of orders.

Setting it up

Turn it on, choose which product becomes the tick-box add-on and where it should appear, and match the look to your store. It goes live on your product pages right away, and you can change the offer or its styling whenever you like.

It's a ready-made feature you add in a click. Want it to behave differently — a different add-on per product, say? Describe it in plain English and Trooix builds that for you.

Questions, answered

What is a checkbox upsell?

It's a tick-box under your Add to cart button that lets a shopper add a matching product — like a gift box or warranty — to their cart in a single tick, at its normal price.

Will it slow down or clutter my product page?

No. It sits quietly under Add to cart and only adds the extra item when a shopper chooses to tick it — no pop-up, no second page.
