What it means
A B2C business sells to the person who will use the product: supermarkets, airlines, streaming services, coffee shops and online retailers are all B2C. One person usually decides, pays on the spot by card, and does not negotiate the price.
That changes the shape of the accounts. Revenue is spread across a very large number of small transactions, so no single customer leaving has any effect, which makes the top line steadier than a B2B equivalent.
On the other hand demand swings with season, weather, fashion and advertising, so the risk sits in volume rather than in named accounts. Cash flow is usually friendlier.
Consumers pay at or before delivery, so there are few trade receivables, and a retailer who sells stock before paying its suppliers can run on negative working capital. The trade-off is inventory risk, because unsold stock has to be discounted and that discount comes straight off gross margin.
The metrics are per-order and per-customer rather than per-contract. Average order value, gross margin per order, customer acquisition cost, repeat purchase rate, returns rate and contribution margin after marketing are the ones that get argued about in management meetings.
A business can grow revenue quickly and still lose money if the cost of buying each order exceeds the gross profit it produces. The usual nuance is that acquisition cost is not a one-off.
If the average customer buys three times, the cost of winning them is spread across three orders, which is why repeat rate matters more than any single campaign result.
In practice
Real-world examples.
Example
A coffee chain tracks an average transaction value of $6.40 and serves 1,900 customers a day in a flagship store. Adding a $1.20 pastry to one order in four lifts daily revenue by $570 with no extra marketing spend at all.
Example
A fashion retailer discovers that 28% of online dress orders are returned. Because each return costs $9 in postage and handling, the finance team restates gross margin net of returns and finds the category is barely profitable.
Example
A subscription box company spends heavily on social advertising and reports strong revenue growth, but the average subscriber cancels after two months. With acquisition cost of $34 and monthly contribution of $12, each new subscriber loses $10 before cancelling.
Formula
Calculation
Contribution per order = (average order value multiplied by gross margin percentage) minus customer acquisition cost per order. An online homeware retailer has an average order value of $65 and a gross margin of 60%, so the gross profit per order is $65 multiplied by 0.60, which is $39. It spends $50,000 on advertising in a month and receives 2,500 orders, so the acquisition cost per order is $50,000 divided by 2,500, which is $20. Contribution per order is $39 minus $20, which is $19. If the average customer places three orders over their life, and only the first is paid for with advertising, lifetime contribution is $39 plus $39 plus $39, which is $117, less the $20 acquisition cost, giving $97 per customer.Case study
Seen in the real world.
Mapleleaf Mats is an illustrative, fictional online seller of yoga equipment used here to show how B2C growth can mislead. Revenue tripled in a year to $6,000,000, and the founders assumed scale alone would fix the losses.
A review of the numbers showed an average order value of $48, a gross margin of 55% and therefore gross profit of $26.40 an order, against an acquisition cost that had crept from $18 to $31 as the company bid for broader keywords. Contribution on new customers had fallen to a loss of $4.60 an order, and only repeat buyers were profitable.
In this fictional case the fix was unglamorous. Mapleleaf cut spend on the worst-performing channels, raised the free delivery threshold to orders over $60 to lift average order value, and built an email programme aimed squarely at a second purchase.
Watch out
Common mistakes.
- Judging a campaign on revenue rather than on contribution after the cost of goods and the advertising that produced it.
- Quoting gross margin before returns and discounts in a category where both are high.
- Assuming acquisition cost stays flat as spend rises, when the cheapest audiences are always bought first.
Questions
People also ask.
Why do B2C businesses often have little in receivables?
Because consumers pay at the point of sale by card, so cash arrives within days rather than on invoice terms.
Is a high repeat purchase rate more valuable than a low acquisition cost?
Usually yes, because a customer who buys several times spreads the one-off cost of winning them across every later order.
Can a B2C business run on negative working capital?
Yes, a retailer that sells stock quickly and pays suppliers on longer terms is funded partly by its own suppliers, though that only holds while sales keep moving.
