Free Delivery, Costed Honestly: Minimum Baskets, Delivery Zones and the Day the Offer Stops Paying
In free delivery offer costing minimum basket zones, the word free is the most expensive part of the offer. The customer pays nothing for the drop, but the business pays for fuel, driver time and packaging on every order, and the offer only works when those costs are smaller than the extra sales it brings in.
That is why the offer has to be costed before it is advertised. A minimum basket, a sensible delivery zone and a monthly check are what keep a generous promise from quietly eating the margin on every order.
Where Free Delivery Offer Costing Minimum Basket Zones Begins
Start with the cost of one drop. Fuel, driver time and packaging, added together, are what a free delivery actually costs the business, and that figure is the floor the offer has to stand on. When free delivery offer costing minimum basket zones is done this way, the minimum basket is set to cover the drop and leave a margin, not guessed from what a rival charges.
The Minimum Basket That Covers the Drop
The minimum basket is the order size at which a free delivery stops losing money. Work out the margin on a typical basket at that size, subtract the cost of the drop, and check that something is left. If the basket has to be so large that customers stop ordering, the offer is the wrong shape, and a smaller zone or a delivery charge is the honest answer.
Our notes on the cost of free extras show the same habit for small giveaways at the counter, and the same rule works here: a free thing is only free to the customer. If the basket cannot carry the cost of the drop, the offer is being paid for out of the margin on every other order.

Delivery Zones Drawn by Real Journey Time
A delivery zone drawn as a circle on a map is a promise the driver cannot keep. Draw zones by real journey time instead: how long the round trip takes in normal traffic, and how many drops fit in a driver’s shift. A zone that is too wide means late deliveries and fuel spent on one order, while a zone that is too tight means customers just outside it feel turned away for no reason they can see.
Driver Time, Fuel and Packaging on Every Drop
The three costs of a drop are easy to undercount. Driver time is the wage for the whole round trip, not just the minutes at the door, fuel is the full journey, and packaging is every bag, box and cold pack that leaves with the order. In free delivery offer costing minimum basket zones, a drop costed on fuel alone is a drop that loses money, because the other two costs are still being paid.
The Monthly Check That the Offer Still Pays
An offer that paid in January may not pay in July, when fuel is higher and orders are smaller. Check it every month: the number of free drops, the cost of each one, and the extra orders the offer brought in. In free delivery offer costing minimum basket zones, the monthly check is the moment the business finds out whether the offer is still earning its keep, and the day to change it is the day the numbers say so.
The Day the Offer Stops Paying
Every free delivery offer has a day when it stops paying, and the honest response is to change it before the losses pile up. Raise the minimum basket, shrink the zone, or charge for delivery beyond it, and tell customers plainly what has changed and why. The IRS guidance on recordkeeping for small businesses explains why dated records of costs and sales matter, and a delivery log is exactly that kind of record.
Keep a simple delivery log: the date, the basket, the zone and the cost of the drop, so the monthly check is a short job, not a search. Our notes on the product line profit margin check show how to test whether one part of the business is carrying another, and free delivery is the part that most often needs that test.
Telling Customers When the Offer Changes
Customers accept a change they understand and resent one they discover at the till. Give notice before the minimum basket rises or a zone shrinks, put the new terms where customers order, and train staff to explain the change in one sentence. A clear change, given in good time, keeps the customers the offer was meant to win.
Frequently Asked Questions
Should the minimum basket be the same for every delivery zone?
No. In free delivery offer costing minimum basket zones, a far zone costs more per drop than a near one, so the basket that covers a near drop may lose money on a far one. Set the basket by zone, or charge for delivery beyond the near zone, and let the cost of each drop decide.
What should go in a delivery cost log?
The date, the basket value, the zone, and the cost of the drop: fuel, driver time and packaging. With those four lines, the monthly check takes minutes, and the day the offer stops paying is visible in the numbers, not a surprise at the end of the quarter.
How do we know if free delivery is bringing in extra orders?
Compare orders with the offer against orders without it, in the same weeks if you can. If the extra orders are few, or the baskets are barely above the minimum, the offer is buying very little, and the money may be better spent on the products themselves.
When should a business stop offering free delivery altogether?
When the monthly check shows the cost of the drops is larger than the extra margin the offer brings in, month after month. Stopping is not a failure, it is the offer doing its job: the numbers said so, and the business listened before the losses grew.
Free delivery works when the drop is costed honestly, the minimum basket covers it, the zones follow real journey time, and the offer is checked every month. In free delivery offer costing minimum basket zones done well, the word free is a promise the business can afford to keep.
