How do I increase average order value?

By cartscaling Reviewed 4 min read

The short answer

Four moves, in the order they usually pay. Set the free shipping line just above your typical order. Build bundles from what people already buy together. Offer one relevant add-on at the cart rather than a wall of suggestions. Then make the larger size or multi-pack the obvious choice on the product page.

Start with the shipping line, because it is the cheapest change you can make

A free shipping threshold is the only lever here that requires no new products, no photography and no development work. It works because it gives a shopper a reason to add something they were already considering.

Set it from your own order data rather than from instinct. Look at the spread of order values and find the point that sits just above the middle of the pack. A line set below your typical order gives away shipping on orders that were already large enough. A line set far above it is ignored, because the gap feels like too much to bridge.

Then make it visible where the decision happens. On the product page, so the shopper knows the rule before they add anything. In the cart, as the remaining amount rather than the threshold. You are 9 dollars away from free delivery is a nudge. Free delivery over 75 dollars is a fact.

Pair it with something to add. A progress message with no suggested item asks the shopper to go browsing again, and most will not. Show two or three small items that close the gap, priced near the amount remaining.

Then measure the whole effect, not the headline. Orders will get larger and your shipping bill will go up. If margin per order rose after both changes, keep it. If it did not, move the line and measure again.

Build bundles from baskets people already create

The best bundles are discovered, not invented. Look at orders that contained more than one item and count which pairs appear most often. Those pairs already have demand. Packaging them saves the customer a decision rather than asking them to make a new one.

Give the bundle a reason to exist beyond a small saving. The starter set for a new customer. The refill pack for someone who has run out. The pair that solves the problem properly, like the item plus the thing it needs to work. A named bundle with an explanation sells better than the same products with a discount attached.

Price it so the saving is visible but modest. Enough to feel like the sensible choice, not so much that customers who would have bought both anyway now pay less. If the components sell well on their own, the bundle discount comes straight out of margin for those buyers, so watch the mix after launch.

Put bundles where the decision is being made, on the product page of each component and in the collection, not only on a bundles page nobody visits.

And be honest about fit. Bundling slow stock with a best seller moves the slow stock and annoys the customer, which shows up later in returns and in the second order that never comes.

One relevant add-on at the cart, not a wall of recommendations

At the cart, attention is short and the decision is nearly made. One well chosen item converts. A grid of eight products gets ignored, because it turns a small decision into a browsing task.

Choose the add-on by relationship rather than by popularity. The consumable that goes with the device. The care product that protects the thing they just bought. The spare that always gets ordered three months later. Something under a fifth of the cart value, so it feels like a small yes.

Keep the mechanics light. Adding it should not reload the page, empty the cart or send the shopper back to a product page to choose a variant. Every extra step loses most of the people who were willing.

The same logic applies after the order. A post purchase offer on the confirmation page reaches someone who has already paid and cannot lose you the original sale, which makes it the safest place to try a larger add-on.

What to avoid is the aggressive version: an interruption between the cart and the checkout, a countdown, a pre ticked box adding something the customer did not choose. These raise the average this week and cost you refunds, chargebacks and trust over the quarter.

Measure the add-on on take up rate and on its effect on checkout completion. If the completion rate falls, the offer is in the wrong place.

Make the bigger size the obvious choice on the page

For anything sold in sizes, quantities or terms, the way options are presented decides which one people pick, and most stores present them as a plain list.

Show the unit price next to each option. Per hundred millilitres, per wash, per serving, per month. When the larger option is better value, saying so plainly converts far better than expecting the shopper to divide in their head.

Pre select the option you want to sell, so long as it is genuinely the better deal for a typical customer. Defaults do a lot of quiet work.

Explain why a larger size makes sense for this product. It lasts a season, it is the size most people reorder, it saves a delivery. A reason beats a saving on its own.

For consumables, offer a subscription with a small saving and easy cancellation. It raises the value of the relationship rather than only the order, and it removes the reordering decision entirely.

For products where a second unit is plausible, offer the two pack as a named option rather than asking people to change a quantity field. Quantity fields are invisible. Options are not.

Across all four moves, watch margin per order rather than average order value alone. The aim is more money kept per order, and the average is only the visible part of that.

It raises it arithmetically and may lower order count, so judge the change on total gross profit rather than on the average. A price rise is a separate decision that happens to move this metric.

They do when most buyers would have purchased the larger size anyway. Look at how many orders already choose the big option before you discount it, and keep the saving small enough that the extra volume covers it.

At the cart for small items, and on the order confirmation for larger ones. Avoid placing an interruption between the cart and the checkout, since anything that slows payment can cost more orders than the add-on earns.

Yes. Multi-packs, subscriptions, accessories and gift options all raise a single product order. The route is quantity and commitment rather than variety.
