Ecommerce Fulfilment: What Is a Good Cost Per Order

One of the most dangerous numbers in ecommerce is the one many founders never calculate.

Not customer acquisition cost.

Not conversion rate.

Not average order value.

It’s fulfilment cost per order.

The reason is simple.

A business can be growing, generating revenue and acquiring customers while quietly

becoming less profitable with every order shipped.

Many founders only discover this when cash flow becomes tighter than expected.

Others discover it when they finally compare their fulfilment costs against competitors.

By then, the issue has often existed for months.

Understanding your fulfilment cost per order is one of the fastest ways to improve operational decision-making and identify hidden inefficiencies.

The challenge is that there is no universal benchmark.

A good fulfilment cost depends entirely on your business model.

However, there are ways to determine whether your current costs are healthy or becoming a problem.

Why Fulfilment Cost Per Order Matters

Most ecommerce brands focus heavily on sales metrics.

That makes sense.

Revenue growth is exciting.

Fulfilment costs are not.

However, profitability is often won or lost inside operations rather than marketing.

Consider two brands:

Both generate £1 million in annual revenue.

Both have similar products.

Both have similar customer acquisition costs.

One has a fulfilment cost per order of £4.50.

The other sits at £8.50.

Over thousands of orders, the difference becomes substantial.

Consequently, understanding fulfilment economics is critical for sustainable growth.

How to Calculate Fulfilment Cost Per Order

The formula itself is straightforward.

Total Fulfilment Costs ÷ Total Orders Shipped

However, the challenge lies in knowing what to include.

Many businesses underestimate fulfilment costs because they only count shipping.

A more accurate calculation includes:

• - storage costs

• - receiving costs

• - pick and pack fees

• - shipping charges

• - packaging materials

• - returns processing

• - warehouse labour

• - fulfilment software

• 
  

Only then do you see the true operational cost of getting an order to a customer.

Why Most Ecommerce Brands Underestimate Their Costs

The problem usually starts during growth.

Founders often begin by packing orders themselves.

The costs appear low because:

• 
  

• - labour is not tracked properly

• - storage is absorbed into existing space

• - operational time is not valued

As order volume increases, these hidden costs become more significant.

Yet many businesses continue using outdated assumptions.

As a result, profitability can be overstated.

There Is No Universal Benchmark

One of the biggest misconceptions in ecommerce is the belief that there is a perfect fulfilment cost percentage.

There isn’t.

Consider these examples.

Beauty Brand

• 
  - Small products

• - High margins

• - Low shipping weight

Typically able to absorb higher fulfilment service levels.

Furniture Brand

• - Large products

• - Higher shipping costs

• - More complex delivery requirements
  

Very different economics.

Subscription Business

• 
  

• - Predictable order profiles

• - Standardised packaging

• - Repeat fulfilment cycles

• 
  

Often benefits from operational efficiencies unavailable elsewhere.

Comparing these businesses directly would be misleading.

A Better Benchmark

Rather than asking:

“What should my fulfilment cost be?”

Ask:

“What percentage of revenue does fulfilment consume?”

This provides far more context.

For example:

A £100 order with a £7 fulfilment cost looks very different from:

A £20 order with the same £7 fulfilment cost.

The percentage matters.

Not just the number.

The Warning Signs Your Costs Are Too High

There are several indicators worth watching.

Your Fulfilment Costs Are Rising Faster Than Revenue

This often indicates inefficiency.

Margins Keep Shrinking

Even when sales grow.

Shipping Costs Are Increasing Every Quarter

Without a corresponding improvement in customer experience.

Storage Costs Continue Climbing

Often due to poor inventory planning.

Returns Are Becoming More Expensive

Particularly common in fashion and high-volume consumer categories.

What Actually Drives Fulfilment Costs?

Many businesses assume shipping is the biggest factor.

Sometimes it is.

Often it isn’t.

The biggest drivers usually include:

Inventory Complexity

More SKUs generally create more operational complexity.

Order Profiles

Multi-item orders require more handling.

Product Characteristics

Weight and dimensions influence shipping economics.

Returns Volume

Returns create additional processing requirements.

Warehouse Efficiency

Operational discipline matters more than many businesses realise.

The Fulfilment Cost Trap

One of the most common mistakes is trying to reduce costs by focusing on the wrong area.

For example:

A business negotiates a slightly lower shipping rate.

Meanwhile:

• - picking errors increase

• - customer complaints increase

• - support tickets increase

The result?

Costs move from one area of the business to another.

True optimisation improves both cost and performance.

More SKUs generally create more operational complexity.

Order Profiles

Multi-item orders require more handling.

Product Characteristics

Weight and dimensions influence shipping economics.

Returns Volume

Returns create additional processing requirements.

What High-Growth Brands Measure

The strongest ecommerce operators rarely look at fulfilment cost per order in isolation.

Instead, they monitor:

• - fulfilment cost per order

• - order accuracy

• - delivery speed

• - customer satisfaction

• - repeat purchase rates

• - return rates

Together, these metrics tell a more complete story.

The Relationship Between Fulfilment and Profitability

Research from Deloitte consistently highlights the relationship between operational maturity and financial performance.

Businesses with stronger supply chain capabilities often achieve better efficiency and service outcomes than competitors.

Fulfilment is only one part of that equation.

However, it is one of the most visible.

When Lower Costs Become a Problem

A surprising observation emerges when analysing successful ecommerce brands.

The cheapest fulfilment operation is rarely the best one.

In fact, some of the strongest brands deliberately invest more in fulfilment.

Why?

Because they recognise the impact on:

• - customer retention

• - reviews

• - repeat purchases

• - brand reputation

Therefore, the objective should not be minimising fulfilment cost.

It should be optimising fulfilment value.

The Better Question

Instead of asking:

“How do we reduce fulfilment costs?”

Ask:

“How do we improve fulfilment efficiency?”

The answers are usually more valuable.

Better forecasting.

Better inventory management.

Better warehouse processes.

Better provider selection.

Those improvements often reduce costs naturally.

Final Thoughts

A good fulfilment cost per order is not defined by a universal benchmark.

It is defined by whether your fulfilment operation supports profitable growth.

Understanding the number is important.

Understanding what drives the number is even more important.

The most successful ecommerce brands treat fulfilment as a strategic function rather than a

necessary expense.

They measure it.

They optimise it.

Most importantly, they understand how it affects the wider business.

Because in ecommerce, profitability is rarely determined by a single metric.

It is determined by how all the moving parts work together.
