At first glance, revenue may seem stable—but a closer look reveals a subtle, critical shift: customers are ordering less per transaction. Basket sizes are shrinking. Whether driven by inflationary pressure, shifting user behavior, or subtle product and UX changes, the outcome is the same—each order carries fewer items, reducing average order value (AOV) and contribution margin.
Hilbert’s AI Growth Engine provides a systematic method to confront this challenge. It transforms raw data into clarity, structures solutions into projects, and continuously tracks KPIs to break the cycle.

The Shrinking Basket Phenomenon: Macro Stress or Micro Design?
Declining basket size is one of the earliest—and most overlooked—warning signs of weakening purchasing power or product experience friction. When customers begin reducing the number of items per order, it reflects not only financial caution but also a behavioral recalibration in how they engage with the platform.
The drivers behind this phenomenon tend to fall into two categories:
1. Macroeconomic Factors (External Pressure):
- Inflation & Cost Sensitivity: Rising prices make customers more selective, reducing discretionary spending.
- Income Compression: Broader economic stress leads to smaller, necessity-based orders.
- Category Trade-Down: Consumers shift from premium to budget SKUs, maintaining order frequency but lowering total spend.
2. Micro-Level Platform Influences (Internal Triggers):
- UX & Checkout Friction: Added fees, redesigned carts, or delivery thresholds nudge users toward fewer items.
- Personalization Biases: Algorithms emphasizing top sellers or “quick buys” can inadvertently narrow exploration and basket variety.
- Delivery Fee Models: Introducing per-order fees (rather than free or bundled thresholds) discourages larger baskets.
Empirical research aligns with this pattern. A 2022 NielsenIQ study found that average basket sizes declined by 12–15% in inflationary periods, even as total order counts remained flat. Another analysis by McKinsey (2023) showed that digital shoppers exposed to higher delivery fees reduced basket count per order by 18% on average.
Operationally, shrinking basket sizes compress contribution margin since fixed fulfillment and delivery costs remain constant per order. The result is a margin squeeze: more transactions, but lower profit per transaction.
Hilbert’s AI Growth Engine isolates the source of this shift by decomposing order-level data—identifying whether the trend originates in economic pressure, fee structure, category mix, or design friction. It can quantify the degree to which smaller baskets reflect external demand stress versus internal system design effects, guiding corrective action before revenue erosion becomes visible.
Traditional Approach vs. Hilbert’s AI Growth Engine
Traditional teams detect declining basket sizes only after AOV reports show a drop. These surface-level metrics fail to reveal why the shrinkage occurs—whether it’s caused by macroeconomic stress, UX friction, or strategic changes in product mix or pricing.
Hilbert’s AI Growth Engine goes deeper. It connects transaction-level behavior, macro context, and platform design changes in one analytical framework. By mapping cause and effect, it helps identify whether the basket contraction is reversible and which interventions (UX design, threshold incentives, loyalty mechanics, or pricing recalibration) would restore healthy order composition.
Some examples of questions the system is able to answer:
- How has average basket size evolved over the past 12 months across product categories?
- What percentage of total orders fall below free-shipping or delivery fee thresholds?
- Which customer segments are most responsible for the decline in items per order?
- How has the distribution of basket values shifted since the introduction of new fees or UX updates?
- Which products are being dropped from baskets most frequently before checkout completion?
- What correlation exists between inflation-adjusted prices and basket size over time?
- How does basket shrinkage differ between returning and first-time users?
- How has fulfillment or delivery margin changed as a result of smaller orders?
- What external factors (price inflation, seasonality, or competitor discounts) align with recent basket compression trends?
- What is the projected margin impact if average basket size continues to decline by 5% per quarter?
