Owned vs Outsourced Fleet Capacity: How Retailers in France Should Optimise It in 2026

Owned versus outsourced fleet capacity is the decision about which delivery routes a retailer runs with its own vehicles and drivers and which it buys from carriers, couriers or a 3PL by the day or the contract. In France the answer is shaped by three things: diesel at record highs, low-emission zones that can strand an ageing owned fleet, and transport contract law that passes fuel costs through to the buyer and caps payment terms at 30 days. The best French retailers own only the base load they use almost every day and buy the rest, and an agentic TMS such as Locus makes that split a daily decision instead of an annual budget line.

Why Owned vs Outsourced Capacity Matters in France: The Business Case

Fuel is the most visible cost. The average price of diesel in France reached €2.408 per litre on 21 September 2026, up 11.4 centimes in a week and 45.8% over September 2025, according to the official prix-carburants.gouv.fr file.

Vehicle access is contested. The Constitutional Council censured the abolition of the ZFE on 21 May 2026 as a legislative rider, so the zones stay in force, and in the Grand Paris zone Crit’Air 3 vehicles have been barred since 1 January 2025.

French delivery fleets are mostly diesel. France had 6.3 million light commercial vehicles at 1 January 2022, 95% of them diesel, according to the ministry’s statistics service SDES.

Large fleets carry a tax incentive. The annual incentive tax on light-vehicle fleets of more than 100 vehicles sets low-emission targets of 18% in 2026 and 25% in 2027, a cost that sits with owned vehicles.

Payment terms are tight. Road freight payment is capped at 30 days from invoice, and in 2026 a Médiateur des entreprises committee recommended 15 days in response to fuel costs, though the recommendation is not binding.

What Is Different About Fleet Capacity Decisions in France

Fuel revision is built into the contract. Under article L3222-1 of the Code des transports, the agreed transport price is revised automatically to reflect changes in energy costs between the contract date and the transport, the carrier must show those charges on its invoice, and the provisions are mandatory. A retailer that outsources therefore keeps its diesel exposure, only with a lag and a formula.

Zone rules differ by metropolis. Each metropolitan area sets its own perimeters, hours and Crit’Air thresholds, so an owned vehicle that is eligible in one city can be barred in another, and the same applies to a carrier’s vehicle.

Direct action reaches the shipper. Article L132-8 of the Code de commerce lets a carrier claim payment from the shipper and the consignee as guarantors of the price, so a retailer that has already paid an intermediary can face a second claim if that intermediary does not pay the carrier.

Fleet greening is a cost of owning. Fleets above the 100 vehicle threshold face the incentive tax if their low-emission share falls short, which changes the cost of keeping older diesel vans.

Demand is spiky. Promotions, seasonal peaks and click-and-collect surges mean the number of routes changes from day to day, so the question is never one vehicle count but a daily mix.

How to Decide the Owned and Outsourced Split in Six Steps

1. Measure demand by day, not by average

Build the daily distribution of route needs for each depot over a full year. The average hides the peaks and the quiet days, and the split depends on how many days each extra vehicle would actually run.

2. Cost each vehicle-day under each option

Compare an owned vehicle (lease or depreciation, driver, insurance, tax and a renewal reserve for ZFE) with a contracted vehicle (day rate, any minimum commitment, fuel indexation) and an independent courier. The table below shows how the break-even moves.

3. Own the base load only

Add an owned vehicle only if it would run on roughly 95% of working days. In the model below, that means sizing the owned fleet at the level of demand that is exceeded on all but the quietest days, and buying everything above it.

4. Contract the flex layer with the French rules in mind

Agree an indexation formula based on the energy charges identified in the contract, payment terms within the 30-day cap, and a minimum-day commitment that matches your base-load forecast. Check who pays the carrier when an intermediary sits between you and the vehicle.

5. Allocate daily by zone and vehicle eligibility

Assign each route to the cheapest eligible vehicle: owned for the base load, contracted for the flex, couriers for the unplanned days. Crit’Air class, zone hours and curb limits are constraints on that assignment.

6. Re-run the split whenever the inputs move

Diesel, ZFE rules, vehicle prices and demand all change. A quarterly review, or an automatic re-run when an input moves, keeps the split from drifting.

Owned vs Outsourced Capacity: Key Differences

The break-even figures come from an illustrative model, not from customer data. Inputs: an owned van costs €52,000 a year fixed (driver, lease, insurance, tax) plus €70 per route-day variable (fuel, maintenance, parking); a contracted van costs €290 per route-day with a 20-day minimum; an independent courier costs €340 per route-day; a year has 250 route-days. Replace them with your own numbers.

Sensitivity tells the story. Raising the owned fixed cost by 20% moves the break-even from about 236 to 284 days, while cutting the contracted rate by 20% moves it to 321, which is beyond the 250 days available, so owned never wins. Adding a €3,000 annual ZFE renewal reserve to the owned van moves it to 250 days. A 20% rise in diesel moves it only to about 231 days, because the contracted rate is indexed to fuel too, assuming fuel is about €30 of the owned daily cost and 20% of the contracted rate. And if better planning lets an owned van deliver 20% more per day, the break-even falls to about 224 days.

What to Look for in Capacity Planning Software for French Retailers

One view of owned and outsourced capacity. Look for a single plan that holds owned vehicles, contracted carriers and couriers together, rather than a fleet tool and a separate carrier spreadsheet.

Demand forecasting by day and depot. The base-load rule depends on the daily demand distribution, so the platform should forecast and learn from it.

Zone and vehicle eligibility as constraints. Crit’Air class, zone hours, curb limits and vehicle size should sit in the plan, not in a driver’s memory.

Carrier scoring and allocation. Check how the platform scores carriers on cost, service and capacity, and how it falls back when one is full.

Governance and audit trail. Look for explainable decisions, autonomy levels and human approval, so finance and operations can see why a route was owned or bought.

Owned and Outsourced Capacity in Action: Real-World Results

Neither deployment is in France. They show what a combined plan does for a mixed fleet.

A global freight operator with 4,500+ drivers across 51 service centres. The operator ran 1,500+ captive drivers alongside 3,000+ third-party transporters, and planning was fragmented across sites. With centralised dispatch across both workforces, the execution rate rose from 75% to 92%, uncovering $14M+ in annualised capacity across 25 sites. Read the freight operator case study.

A Canadian multi-modal retailer. Six legacy systems handled dispatch for different modes. After consolidating them on one platform, the retailer reached 99%+ on-time delivery, cut manual dispatch by 80%+, held exceptions to under two hours and saved $1M+. Read the retailer case study.

Common Owned vs Outsourced Mistakes in France

Sizing the owned fleet to the average. An average-sized fleet is idle on quiet days and short on busy ones. Size it to the base load and buy the peaks.

Assuming outsourcing removes fuel risk. Under L3222-1 the price is revised with energy costs, so diesel still reaches the retailer through the contract.

Overlooking direct action. Paying an intermediary does not always end the exposure. Confirm the payment chain and take legal advice on contract terms.

Treating ZFE as a fixed cost. Zone rules shift by city and by court ruling, so a fleet bought for today’s perimeter can lose access tomorrow.

Frequently Asked Questions

When does owning a delivery fleet beat outsourcing in France? An owned vehicle wins when it runs on almost every working day. In the illustrative model here, the break-even is about 236 of 250 route-days, so ownership suits the base load and outsourcing suits everything above it. Use your own costs to find your number.

How do ZFE rules affect owned vs outsourced capacity? The zones remain in force after the Constitutional Council’s 21 May 2026 decision, and thresholds differ by metropolis. An owned vehicle that loses access carries the renewal cost, while a carrier prices that risk into its rate. In the model, a €3,000 annual renewal reserve moves the break-even to 250 days.

Does outsourcing protect a retailer from rising diesel prices in France? Not fully. Article L3222-1 of the Code des transports revises the agreed transport price with energy costs, and the carrier shows the charges on its invoice. Diesel averaged €2.408 per litre on 21 September 2026, so the pass-through is material.

What are the payment terms for road transport subcontractors in France? Payment for road freight is capped at 30 days from the invoice date. A 2026 Médiateur des entreprises committee recommended 15 days, but that is not a binding rule.

What is direct action and why does it matter to a retailer? Article L132-8 of the Code de commerce lets a carrier claim payment from the shipper and the consignee. A retailer that paid an intermediary can face a claim from the carrier if the intermediary did not pay it, so confirm payment chains and take legal advice.

Can Locus plan a mixed owned and outsourced fleet in France? Locus plans owned vehicles, contracted carriers and couriers in one decision, using its Capacity, Carrier and Dispatch agents, and its proof points come from other regions. Ask Locus to confirm French language support, ZFE rule handling and French carrier connectors for your network.
