AOV planning
Use case
Pricing checks
Most fee models include a percentage charge plus a fixed per-order charge. This makes low-AOV orders more fee-sensitive.
- Fee per order = (Order value * percentage fee) + fixed fee
- Net after fee = Order value - fee
- Fee ratio = fee / order value
Run fee impact scenarios at your common order values. If fees consume too much margin at lower AOV bands, adjust bundle strategy, minimum order incentives, or discount policy.
- Check fee load at low, median, and high AOV
- Compare fee ratio before and after discount campaigns
- Track fee impact by channel and payment method
Use fee thresholds with your order-level margin alerts so teams can see when payment costs are driving thin or negative net profit.
Why do fees hurt low-AOV orders more?
The fixed fee component is a larger percentage of smaller orders, which compresses net margin.
Should fee assumptions be channel-specific?
Yes. Different channels and payment methods can shift average order values and fee burden.
How often should fee assumptions be reviewed?
Review monthly and after major pricing, discount, or payment mix changes.
