# Why Profitable Delivery Fleets Rethink Their Network First

Many delivery fleets focus on day-to-day execution, without looking at the bigger picture. Distribution networks are “good enough” for now, but aren’t built to keep up with changing business needs.

Depot locations don’t match customer geographies. Service levels are inconsistent. Some vehicles sit underutilised while other routes are over capacity.

Left unchecked, these imbalances eat into overall profits.

The most immediate consequence is rising fuel and labour costs. The less obvious impact is lost revenue due to the inability to meet demand.

In this article, we’ll look at how network design shapes cost, capacity and service levels. You’ll find out how fleet leaders use strategic planning software to:

- Choose profitable depot locations
- Right size their fleet
- Fix frequencies and territories

## Choosing Depot Locations

As time goes on, the efficiency of a delivery network degrades. Demand increases in one region and wanes in another, while customers demand tighter delivery windows. Real-estate prices trend upwards and road networks shift.

Depot locations that seemed “OK” five years ago could be chipping away at today’s profits:

- Depot location determines the distance and time to serve customers. Fuel, labour costs and emissions add up across thousands of deliveries.
- A badly positioned depot hampers your ability to offer same-day or express delivery options.
- You may leave revenue on the table if you’re unable to meet demand in certain geographies.

However, the decision to open, close or consolidate depots should not be taken lightly. A poor outcome could lock you into higher logistics costs for years.

That’s why profitable fleets use dedicated software to make decisions about depot location. The right tool can weigh up a large amount of data to model scenarios side-by-side. This helps you answer questions like:

- Where is the most efficient location for a new depot?
- Are there any low-density regions where sales reps should be prospecting more customers?
- Would it be beneficial to switch from distributed to centralised operations, or vice versa?

For each scenario, you can see the impact on cost, delivery density, work hours and service levels. Then you can make an informed decision based on the trade-offs that are most important for your business.

## Right Sizing the Fleet

Fleets tend to remain unchanged for years while fuel prices, [customer demand](https://routinguk.descartes.com/resources/home-delivery-personas?returnPage=6) and geography evolve. Without periodic remodelling, your network could be leaking profits.

Running an oversized fleet is expensive. Financing vehicles comes with interest, while buying vans outright comes with opportunity cost. As vehicles sit still, you’re paying for licensing, compliance, insurance, maintenance and parking space.

With too few vehicles, deliveries are delayed and customer retention declines. Routes are long, driver overtime compounds and you may be reliant on third-party providers. That introduces unpredictable costs into the mix.

As for vehicle type, the fleet composition that worked ten years ago probably doesn’t cut it today. Maybe some of these challenges sound familiar:

- Light vehicles make multiple runs to meet demand in [urban areas](https://routinguk.descartes.com/resources/the-urban-logistics-challenge?returnPage=9).
- You don’t have the capacity to deal with volume spikes.
- Large vehicles run half empty, increasing the cost per stop.
- You [don’t have enough skilled drivers](https://routinguk.descartes.com/resources/overcoming-the-workforce-and-driver-shortage-challenge?returnPage=3) to operate specialised vehicles.
- Vehicle type hasn’t kept up with shifting product categories.
- You’re struggling to meet [carbon reduction goals](https://routinguk.descartes.com/resources/sustainable-logistics-101-a-guide-fleets).

With a dedicated solution for network remodelling, you can compare potential fleet mixes side-by-side. Software considers real-world data to produce solutions that humans might have missed.

For example, a planner might assume that larger trucks means fewer trips and lower stops. The software might demonstrate that adding a small number of mid-sized vehicles would reduce empty miles on low-density routes.

## Fixing Frequency and Territories

With the right delivery network in place, you can start to plan frequencies and territories.

On the surface, these decisions are driven by customer service requirements. But planning should also consider cost, workload and delivery density.

If plans are fixed without these constraints in mind, you end up with routes that are expensive and unbalanced. Territories are neatly drawn, but cost per stop is high. Monday might be overloaded while Wednesday sees drivers at a loose end.

In the end, it’s customer service that suffers. Low-value accounts may be overserviced while high-value deliveries are delayed because they fall on busy days. Daily route planning is a challenge because there’s no logical place to slot in new stops.

Strategic planning software helps you build fixed routes that balance customer demands and profitability. But most solutions take several steps to produce an optimal plan: territories must be assigned before frequencies are decided; delivery days are then selected before routes finally sequenced.

With this process, frequency planning is a matter of guesswork and planners often need to repeat steps over and over.

That’s why Descartes takes a single-pass approach to strategic planning.

### Single Pass Strategic Planning

Descartes’ [strategic planning software](https://routinguk.descartes.com/route-planning-and-scheduling/strategic-route-planning) looks holistically at a delivery horizon to optimise territories, frequencies, delivery days and sequences at the same time.

Outputs can include:

- The most cost-effective depot to serve each stop, rather than arbitrarily defined territories.
- The optimal frequency and best delivery days to serve each customer while balancing routes.

The software creates a strong blueprint for fixed routes, which planners can adjust if necessary. This also opens the possibility to serve high-value customers on a fixed route while orders from low-value customers [fit in dynamically](https://routinguk.descartes.com/route-planning-and-scheduling/hybrid-route-planning).

## Time to Rethink Your Delivery Network?

Remodelling your delivery network is a structural decision that impacts every delivery. When vehicles and depots are aligned with real demand, cost per stop falls and service improves.

Competitive fleets don’t rely on reactive changes. They model, test and refine their network as markets shift. This increases profitability in several ways:

- Delivery density and vehicle utilisation increase.
- Service is more consistent and customer retention improves.
- It's easier to generate revenue from services like next-day delivery.
- You can de-risk decisions like adding a new customer or launching in a new market.
