What it means
Distribution sits between production and the customer, and it quietly consumes a large share of the cost of serving that customer. Every extra day of stock, every part-empty lorry and every rushed courier shipment appears somewhere in the profit and loss account, usually inside cost of sales or operating expenses.
Managing distribution well is therefore a margin question, not just a logistics one. The discipline has two halves that are easy to confuse.
Physical distribution deals with warehouses, vehicles, stock and delivery routes; channel management deals with which wholesalers, retailers, agents or online marketplaces sell the product and what margin each takes. Decisions in one half constrain the other, because a new retail channel usually implies new delivery patterns.
The recurring trade-off is service against cost. Holding stock in six regional centres gives next-day delivery almost everywhere but ties up capital and multiplies handling; running everything from one national site is far cheaper per unit but slower and more fragile.
Most companies set a service target first and then find the cheapest network that meets it. Measurement keeps the function honest.
Distribution cost per unit, distribution cost as a percentage of revenue, on-time-in-full delivery rate, stock turnover and order cycle time are the numbers that appear in most management packs. Tracking them by product and by channel usually reveals that a minority of lines or customers absorb a majority of the cost.
The commercial nuance is that distribution decisions are hard to reverse. Leases, contracts with hauliers, exclusivity granted to a distributor and investment in handling equipment all lock a business into a shape for years.
That is why the analysis deserves proper attention before commitment rather than after.
In practice
Real-world examples.
Example
A craft brewery moves from selling through three wholesalers to shipping directly to two supermarket chains. Distribution cost per case rises because it now handles storage and delivery itself, but the margin gained from removing the wholesaler more than covers it.
Example
An online furniture retailer discovers that 12% of its orders account for 40% of its delivery cost, all of them bulky items sent to remote postcodes. It introduces a surcharge for those postcodes and steers customers towards a click-and-collect option.
Example
A pharmaceutical firm splits its network so that temperature-controlled products ship from one specialist centre while everything else moves through a general carrier. Separating the two flows cuts refrigerated transport spend by roughly a fifth.
Formula
Calculation
Distribution cost per unit = Total distribution cost / Units shipped, and Distribution cost ratio = Total distribution cost / Revenue
A household goods manufacturer reports annual distribution costs of $2,400,000, made up of $900,000 of warehousing, $1,200,000 of freight and $300,000 of final-mile delivery. It shipped 480,000 units and generated revenue of $24,000,000.
Distribution cost per unit = $2,400,000 / 480,000 = $5.00
Distribution cost ratio = $2,400,000 / $24,000,000 = 0.10, or 10% of revenue
The operations team proposes consolidating shipments so that lorries leave fuller, which it expects will cut the cost per unit to $4.40 at the same volume. The annual saving is ($5.00 - $4.40) x 480,000 = $0.60 x 480,000 = $288,000, which would take total distribution cost to $2,112,000 and the cost ratio to $2,112,000 / $24,000,000 = 8.8%. Against a project cost of $120,000 in new scheduling software and training, the payback is comfortably inside the first year.Case study
Seen in the real world.
Bramblewood Home is a fictional homewares business used purely as an illustrative example. It grew from a single shop to 140 stockists and an online store, and its distribution arrangements grew with it in an unplanned way: two leased warehouses, four hauliers, and a courier account used whenever something went wrong.
A review found that distribution cost had reached 13% of revenue against an industry norm nearer 8%, and that emergency courier shipments alone cost $410,000 a year. The underlying cause was not transport pricing but stock placement, because slow-moving lines occupied the better-located warehouse while fast-moving lines sat in the cheaper one further from customers.
Bramblewood swapped the contents of the two warehouses, consolidated from four hauliers to two, and set a rule that no order could be sent by express courier without a manager's approval. In this illustrative case distribution cost fell to 9.4% of revenue within a year without any new building or vehicle, showing that the biggest gains often come from organising what already exists.
Watch out
Common mistakes.
- Judging distribution purely on transport cost per mile, which ignores warehousing, handling, stock holding cost and the cost of failed deliveries.
- Applying a single service level to every product and customer, so low-margin items receive the same expensive next-day treatment as the most profitable lines.
- Granting a distributor exclusivity over a territory without performance conditions, which leaves the manufacturer stuck if that partner underperforms.
Questions
People also ask.
Is distribution management the same as supply chain management?
No, supply chain management covers the whole flow including suppliers and production, while distribution management focuses on the stretch from finished goods to the customer.
What is a reasonable distribution cost ratio?
It depends heavily on product weight, value and channel, but many consumer goods businesses run somewhere between 5% and 12% of revenue.
Should a growing business outsource distribution?
Outsourcing to a third-party logistics provider converts fixed cost into variable cost and suits volatile volumes, while owning the operation makes more sense once volumes are large and predictable.
