What it means
A flat delivery fee can be simple, but a long trip may cost more to serve than a nearby one. Zone pricing divides the area into defined bands or map regions and applies a stated rule to each, and it does not require every menu item to have a different price.
Toast's own-driver guidance describes mileage-based delivery fees and distance thresholds, noting that its threshold uses driving distance for that setup, while Square documents delivery regions, fees and minimum orders for local delivery, so check the live platform configuration. Start with the delivery area, because a customer outside the service area is not merely in a high-fee zone and the order may be unavailable, so avoid presenting a fee for a route no provider can actually serve.
Choose the zone method, since a road-distance band can fit driving cost better than a straight-line circle but the software must calculate it reliably, while postal codes or polygons may be easier to explain in some markets. Measure costs by zone, including driver time, vehicle costs, courier charges, packaging and failed trips on a consistent basis.
Suppose an outer-zone delivery costs $15 in comparable variable expense and the customer pays a delivery charge of $12, so the fee alone has a shortfall of $3. The whole order might still contribute positively if its item margin covers that amount.
Likewise an inner-zone order may cost $8 to deliver and have a $5 fee, yet its basket contribution could still make it worthwhile, so assess total order contribution after relevant costs instead of calling the fee difference the profit or loss on the entire order. Minimum orders are another lever, as a higher minimum in a costly zone can spread delivery expense across more items, though it may deter demand and should be tested against order count and customer satisfaction.
Set a free-delivery threshold carefully, because it can encourage larger baskets but free delivery on a high-cost trip may erase the incremental margin. Check the after-discount economics, not only basket value.
Disclose the fee before late checkout by showing the zone, fee and any minimum clearly once a customer gives a delivery address, because a surprise charge after a basket is built can lead to abandonment and complaints. Keep tax, service fees and tips separate where required, since Toast's guidance distinguishes a delivery service charge from gratuity and the treatment depends on local law and platform configuration.
A provider may set its own courier fee while the merchant sets a customer-facing charge, so record who pays the difference and whether a marketplace collects an additional fee. Avoid excessive complexity, since a menu of many overlapping charges is difficult for staff and customers to follow, and use the fewest zones that represent a real cost or service difference.
For an owner, zone pricing is a service-cost rule, not a penalty for living farther away, and clear boundaries, fair disclosure and real cost evidence matter more than an elegant-looking map.
In practice
Real-world examples.
Example
A restaurant charges 5 for a nearby zone and 12 for an outer zone, with both fees shown after address entry. It checks that drivers serve both areas within the promised window.
Example
A grocer sets a higher minimum order in a distant district rather than a large flat delivery surcharge. It tests whether basket contribution covers the trip.
Example
A customer's address sits on a zone boundary. The business tests the route and updates the map rule so the price is reproducible at checkout.
Formula
Calculation
Delivery-fee coverage by zone = Customer delivery fee - Variable delivery cost per completed order in that zone
Worked example. In the outer zone the fee is $12 and the variable cost is $15, so coverage is $12 - $15 = -$3. In the inner zone the fee is $5 and the cost is $8, so coverage is $5 - $8 = -$3 as well.
- If the average basket margin is $9 before delivery, the outer-zone order contributes $9 - $3 = $6 and the inner-zone order also contributes $6.
- Add other order costs to judge the full order; do not call -$3 the order profit.Case study
Seen in the real world.
This entirely fictional case follows Birch Pantry, an invented grocer. It charged the same delivery fee everywhere, but outer-zone routes often needed an extra courier shift. Management considered raising every customer's fee. The team measured cost and order contribution by distance band, then introduced a small number of disclosed zones and tested addresses at the boundaries. The company and result are invented.
Watch out
Common mistakes.
- Treating a fee below delivery cost as proof the entire order loses money.
- Quoting a zone price before checking whether the address is actually serviceable.
- Adding overlapping fees and minimums that customers only discover at final checkout.
Questions
People also ask.
Must item prices change by delivery zone?
No. A business can vary the delivery fee or minimum order while keeping item prices the same.
Is straight-line distance always used?
No. Some systems use driving distance, postal codes or mapped regions; verify the live setup.
What should be tested before launch?
Real addresses, boundary cases, fee display, delivery capacity and contribution by zone.
