E-commerce: An Operational Brief
For CEOs and business owners running online brands in the £3M to £20M range. Markinly International Management.
The short version
Growth in e-commerce now comes from the back end. Acquisition costs, marketplace fees and shipping costs have risen faster than order values, so the brands growing profitably in 2026 are the ones that know their contribution margin by product and channel, and run inventory, fulfilment and returns as part of the profit engine rather than as cost lines. Marketing can no longer cover for weak operations.
Where the industry stands
Paid acquisition costs more. By industry estimates, digital advertising CPMs have risen by roughly 50 to 60% since 2020.
Every selling channel costs more to run. Marketplace fees and carrier surcharges keep changing, so adding a channel is now an operational decision with margin consequences, not a free growth play.
Gross margin is not profit. Allbirds reported gross margins above 50% in its best years and was sold in 2026 for $39 million, under 1% of its IPO valuation.
Conversion still leaks. Around 70% of carts are abandoned before purchase, and most traffic is now mobile.
SWOT through an operational lens
Strengths and weaknesses describe what we typically find inside e-commerce businesses at this size. Opportunities and threats describe the market around them.
Strengths
- Direct ownership of customer data and the customer relationship
- Fast test cycles on price, offer and product
- Lower fixed overhead than physical retail
- Can scale volume through outsourced fulfilment without adding headcount
Weaknesses
- Revenue is reported by channel; profit by channel rarely is
- Inventory planned from instinct or last year's sales
- A tool and app stack that has grown by addition and is never pruned
- Marketing, merchandising and operations each working from different numbers
- The CEO still approves pricing, promotions and supplier decisions
Opportunities
- Retention and repeat purchase, where the acquisition cost has already been paid
- B2B and wholesale channels with larger, more predictable orders
- Practical AI in forecasting, customer service and product data
- Consolidating tools and integrations to cut cost and data errors
Threats
- Rising acquisition costs and dependence on one or two ad platforms
- Marketplace fee and carrier rate increases
- Low-cost cross-border competitors
- Discount dependency that erodes contribution margin
- The cost of returns
Operational priorities
Know contribution margin by product and channel
The problem: Most brands at this size can report revenue by channel to the penny but cannot say which channel makes money once fees, fulfilment, returns and ad spend are taken out.
The fix: One contribution margin view, by product and channel, refreshed monthly and used in the leadership meeting. It usually exposes a group of products and promotions that lose money on every sale.
What changes: Pricing, promotion and channel decisions are made on margin, not on top-line revenue.
Treat inventory as a cash decision
The problem: Cash is tied up in slow stock while bestsellers run out.
The fix: A demand plan with a named owner, reviewed on a fixed cadence, with reorder points by product class and a clear policy for clearing aged stock.
What changes: Cash is released and stockouts fall on the lines that sell.
Measure fulfilment and returns every week
The problem: Fulfilment runs on trust and is only examined when something goes wrong.
The fix: A short scorecard covering order accuracy, dispatch time, cost per order, and return rate and reason, owned by one person and reviewed weekly. If you use a 3PL, its service levels are written into the contract against the same measures.
What changes: Delivery performance starts to support repeat purchase instead of undermining it.
Put one set of numbers in front of the leadership team
The problem: Each function brings its own dashboard, and meetings become arguments about whose numbers are right.
The fix: One weekly scorecard of a dozen or so measures, each with an owner, and a meeting rhythm built to make decisions rather than to report.
What changes: Problems surface a week after they start, not a quarter later.
Take the CEO out of daily decisions
The problem: Pricing, supplier and promotion calls queue up behind the owner.
The fix: Written decision rights: who decides what, and up to what limit.
What changes: The business moves at the speed of the team, and the CEO gets time back for growth.
If you switched off your three most-used discount codes tomorrow, do you know what would happen to contribution margin, and who in the business would make that call?
