Average order value is one of the few growth levers an online retailer controls almost entirely. Traffic keeps getting more expensive and conversion rates move slowly, but the size of each basket responds directly to the overall customer experience, and the way a brand rewards its customers carries considerable weight in that experience.
That is why the design of an ecommerce loyalty program matters as much as the decision to launch one. The research supports the case, with a warning attached. The 2026 EY Loyalty Market Study found that programs keep performing well on enrollment and ROI, yet consumers now engage with fewer programs, check their rewards less often, and feel more neutral about brands even when programs work as intended.
- Framework 1: Tiered thresholds tied to basket size
- Framework 2: Personalized offers instead of mass promotions
- Framework 3: Paid membership with benefits that outpace the fee
- Framework 4: Account based loyalty for B2B commerce
- Measuring the impact on average order value
- Turning rewards into bigger baskets

EY points to rewards that feel slow and hard to understand as one of the clearest causes of this shift. A program built only to hand out points will struggle to change how much people spend per order. To have a real impact on basket size, value must reach customers in different ways, and that is the purpose of the four frameworks below.
Framework 1: Tiered thresholds tied to basket size
It’s an accepted maxim: Points drive frequency, tiers drive spend.
Tiers give shoppers a visible reason to add one more item. When status depends on cumulative spend or on reaching a set order value, the next level becomes a concrete target instead of an abstract promise.
To make tiers lift average order value (AOV) rather than only purchase frequency:
- Build qualification rules around order value, not order count, so a $150 cart moves a customer closer to the next tier than three $50 carts.
- Show tier progress in the cart and at checkout, where the decision to add or remove items actually happens.
- Reserve the most desirable perks, such as free expedited shipping or early access to new collections, for upper tiers so the jump feels worth it.
- Keep the math simple. EY’s findings suggest that layered, hard to read rewards erode engagement, so a shopper should understand how far they are from the next level at a glance.
Framework 2: Personalized offers instead of mass promotions
Blanket discounts often give away margin without changing how much customers buy, and they teach shoppers to wait for the next sale. Personalized offers, built on the first party data a loyalty program collects, can target the specific categories and price points that expand each customer’s basket.
A BCG’s 2024 retail personalization research makes the economics clear. Returns on personalized offers are as much as three times higher than those of mass promotions, yet retailers on average still put less than 5% of promotional spending into personalization.
The same report found that personalized product recommendations can drive 10 to 20 percentage points of cross sell for multicategory retailers, and that cart abandonment can drop by half when the recommendation engine suggests a suitable substitute product.
Inside an ecommerce loyalty program, this translates into a few practical moves:
- Trigger bonus points on complementary categories based on purchase history, rather than on items the customer already buys every month.
- Set “spend X, earn double points” thresholds for each segment just above its typical basket, so the offer stretches the order instead of rewarding what would have happened anyway.
- Shift a portion of the mass promotion budget to member offers and track the incremental lift against a control group.
Framework 3: Paid membership with benefits that outpace the fee
A paid tier changes the psychology of spending. Once a customer has paid to join, concentrating purchases with that brand becomes the rational way to recover the fee.
A McKinsey’s research on paid loyalty found that members of paid programs are 60% more likely to spend more on the brand after subscribing, compared with 30% for free programs, and that paid programs drive higher purchase frequency and basket size.
There are caveats, though. The same study shows that consumers expect at least a 150% return on their subscription fee, and half of all cancellations happen within the first year, most often because members do not use the benefits enough to justify the cost.
What works in practice:
- Lead with hard benefits that carry an obvious price, such as free shipping or member pricing, to drive sign ups.
- Retain members with experiential perks like early product drops, members only content or personalized services.
- Make benefits usable from day one so customers feel the value of the fee well before the first renewal.
Framework 4: Account based loyalty for B2B commerce
B2B ecommerce is where order value often decides profitability, and where loyalty design differs most from consumer retail. McKinsey’s 2024 B2B Pulse Survey, based on nearly 4,000 decision makers in 13 countries, found that ecommerce is now the top revenue channel for B2B sellers that offer it, accounting for 34% of revenue.
Buyers have also grown much more comfortable placing self service orders above $500,000, and more than half of respondents say they would switch suppliers after a poor omnichannel experience. That shift opens room for an ecommerce loyalty program designed around business accounts rather than individual shoppers.
Fielo, for example, structures B2B commerce loyalty around account level tiers based on cumulative online order value, volume rebates tied to quarterly targets and reorder bonuses, pairing points that drive order frequency with tiers that raise spend per order.
Here are key design principles for B2B storefronts:
- Pool progress at the account level so every buyer in an organization contributes to the same tier.
- Reward new SKU adoption and catalog breadth, which expands baskets beyond routine replenishment.
- Connect the loyalty program to your commerce platform and CRM, so an order placed online, through a sales rep or by phone earns the same rewards, at the same negotiated price, and counts toward the same account tier.
Measuring the impact on average order value
Even a well designed framework needs proof. Since EY warns that strong headline metrics can hide a weakening customer experience, measurement should go further than enrollment counts:
- Compare AOV for members and non members, and for each tier, against a holdout group.
- Track redemption rates and the time to first redemption, because slow value is the earliest warning sign of disengagement.
- Report incremental revenue from personalized offers separately from mass promotions.
- Watch churn and renewal rates for paid tiers closely during the first year.
Turning rewards into bigger baskets
It’s become clear that the common thread across all four frameworks is visibility.
Shoppers and business buyers spend more under three conditions: when they can see what an extra item earns them (hitting a threshold or getting a bonus); when the offer fits what they actually need (complementing the purchase); and when the value of membership shows up quickly enough to justify the fee.
With the right platform, an ecommerce loyalty program can be designed around those three conditions, giving customers a reason to build a bigger basket every time they return.
