A delivery route built in five minutes on a phone costs money every day it runs. Not dramatically: just a few extra miles, a backtrack across town, a driver sitting outside a closed loading dock. Multiply by a year and it’s one of the largest recoverable costs in a local business.
Efficient delivery planning is the work that happens before anyone turns a key: deciding what goes out, grouping it sensibly, putting the stops in the right order, and giving the driver realistic time to do each one. Done well it cuts fuel somewhere in the 10–25% range depending on how loose the current planning is (NextBillion.ai), and it raises on-time performance, which is what customers actually notice.
Ten tips, in the order you’d apply them. They work whether you drive yourself or hand the routes to a courier, and if you’re still deciding which, outsourcing delivery services covers that comparison.
The Bottom Line
- Planning starts with a cutoff. Without one you’re not planning a route, you’re reacting to a day.
- Group stops by zone first, then sequence inside the zone around time windows. Distance comes third.
- Service time per stop is where most routes break: a plan that allows three minutes for a ten-minute drop fails by stop four.
- Track four numbers (on-time rate, first-attempt success, cost per drop, capacity use), or you can’t tell whether a change helped.

- No delivery vehicle expenses
- Optimized local routes
- Pay-per-delivery model
- Average 23% delivery cost reduction
1. Set an order cutoff and plan from one list
A route can only be planned once the orders stop arriving. Pick a cutoff, publish it, and build the day’s route from the list as it stands at that moment.
Without a cutoff, every late order re-plans the whole route, usually badly, and usually by someone who has other work to do. With one, planning becomes a fifteen-minute task done at a predictable time.
Late orders then go into one of two buckets: tomorrow’s route, or a separate same-day run priced accordingly. Mixing them into a planned route is what turns an efficient day into a chaotic one. More on which jobs belong where in same-day delivery for small business.
2. Group stops by zone before you think about distance
The single most effective routing improvement is grouping nearby stops together, which sounds obvious and is routinely skipped when orders are processed in the sequence they arrived.
Draw three to six zones on your delivery map and assign every order to one. Then build routes out of whole zones rather than individual addresses. A route that stays inside one neighbourhood spends its time delivering rather than travelling.
Zones also make capacity planning legible: when one zone consistently fills a route on its own, that’s a signal to split it rather than stretch it.
3. Sequence around time windows, not around mileage
Inside a zone, the shortest route is rarely the best route, because stops have constraints. A restaurant receiving before service, an office with a 4pm cutoff, a dock with receiving hours: those come first, and the mileage arranges itself around them.
Sort every stop into one of three categories:
- Hard window. Must happen inside a stated period or it fails.
- Soft preference. Better earlier or later, but won’t fail.
- Anytime. Fills the gaps.
Place the hard windows, then fit the rest. A route that drives two extra miles to protect a hard window is cheaper than one that misses it.
4. Plan on travel time, not on distance
The shortest route by miles is rarely the fastest route by minutes once urban traffic is involved, and a route planned at 6am behaves differently at 4pm.
If your tool supports historical traffic patterns, use them. If it doesn’t, use your own knowledge: the bridge that backs up, the street that becomes impassable at school pickup, the one-way system that turns a 200-metre hop into a six-minute loop. Write those down somewhere other than one person’s head.
5. Allow realistic service time at every stop
This is where most routes fail. The plan allows three minutes per stop; in practice it’s parking, carrying, waiting for someone to sign, and a conversation.
Time a few of your own deliveries honestly, then set service times by stop type: a kerbside handoff is not a walk-up to a third-floor office, and a wholesale drop with a pallet and paperwork is not either of those.
A route that’s optimistic by four minutes a stop is thirty minutes late by stop eight, and every stop after that is a customer problem.
6. Match the vehicle to the zone and the load
A large vehicle in a dense city centre loses time to parking and manoeuvring; a small one in a suburban zone with bulky orders loses time to return trips.
Decide per route: what’s going out, and what moves it most efficiently. For orders that have grown into pallets, liftgates and bulk wholesale drops, the vehicle question changes shape entirely. See box truck delivery service.
7. Load the vehicle in reverse delivery order
The last stop goes in first. It takes an extra two minutes at the warehouse and saves a minute or two at every single stop, plus it removes the main cause of wrong-item deliveries.
While you’re there: label by stop number as well as by customer name. A driver reading a sequence number doesn’t have to interpret anything.
8. Clean your addresses and contact details before the route, not during it
Incorrect addresses are one of the leading causes of failed deliveries, and failures are expensive: one Loqate study put the average at $17.20 per failed order (via PR Newswire). In the US roughly 97.2% of first delivery attempts succeed, and leading retail operations treat a 90%-plus first-attempt rate as their floor (SmartRoutes delivery success rates).
Three habits fix most of it: validate the address at order entry, always capture a phone number, and keep a notes field that survives between orders: “deliveries through side alley,” “buzzer broken, call on arrival.” That field is worth more than any routing feature.
9. Tell the customer when you’re coming, then tell them when you’ve been
Notification is a planning tool, not just a courtesy. A customer who knows the window is a customer who’s there, which raises first-attempt success and cuts the “where is my order” calls that eat your afternoon.
The working minimum is a dispatch notification, an arrival window or live ETA, and proof of delivery at the end. If your courier doesn’t provide those, you’re planning blind and so is your customer. What to require is covered in technology in courier services.
10. Track four numbers, every week
You cannot tell whether any of the above worked without measurement. Four numbers are enough:
- On-time percentage, measured against the window you promised the customer.
- First-attempt success rate, which is the cheapest cost saving available to most operations.
- Cost per completed delivery, which is also the number you need to compare yourself against a courier quote. The full list of inputs is in the hidden costs of in-house delivery.
- Capacity use: stops completed against stops the route could have held.
Review them weekly for a month. Changes that look clever and don’t move these numbers aren’t improvements.
Where a courier does the planning for you
If deliveries are outsourced, most of this work moves to the provider, and a courier that runs multi-stop routes for a living has already solved sequencing, traffic patterns and service times across thousands of drops.
What stays yours is the input quality: a clean order list by the cutoff, accurate addresses, honest service-time expectations, and real time windows. Garbage in still produces a bad route, however good the optimizer.
So when you’re assessing a provider, ask how routes are built, whether you can see the plan before it runs, and what happens when a stop is added after the route is set. Those questions, and the rest of the selection criteria, are in how to choose a courier service for your business.
Frequently asked questions
What is delivery planning?
Delivery planning is the work done before a route runs: deciding which orders go out, grouping them geographically, sequencing them around time windows and capacity, and allocating realistic service time per stop.
How much can route optimization actually save?
Reported fuel savings generally fall in the 10–25% range, with the largest gains in operations whose routes were previously planned by hand or by order sequence. Time savings usually show up first in on-time percentage.
What is the most common delivery planning mistake?
Underestimating service time at each stop. A route that allows a few minutes too little per delivery compounds into a late afternoon and a string of missed windows.
Should I plan routes by distance or by time?
By time. Travel time reflects traffic, one-way systems and parking, all of which distance ignores, and time windows at the stops themselves should take priority over total mileage.
Start with the cutoff and the zones
Of the ten, two produce most of the gain: set an order cutoff, and group stops by zone before sequencing them. Do those for a fortnight and the rest become easier to see.
Then measure. If your on-time percentage and first-attempt rate both move, the planning is working, and that reliability is what turns one-off orders into standing accounts. Delivery that lands when promised is one of the quieter drivers of repeat customer behaviour, which is where the return on this planning work actually shows up.
