Selling & Business Models
Which ecommerce numbers should I review every month to catch problems early?
The short answer
Review a short chain from traffic to cash: qualified visits, conversion, average order value, contribution profit, acquisition cost, refund and return rates, fulfillment performance, inventory health, repeat purchase, and cash available. Revenue alone can grow while the business gets weaker.
Use one monthly scorecard
| Area | Number | What it can reveal |
|---|---|---|
| Demand | qualified visits by channel | traffic gain or loss |
| Store | product-page and checkout conversion | offer or checkout friction |
| Order | average order value | product mix and bundling |
| Economics | contribution profit and margin | whether orders help |
| Marketing | cost per acquired customer | paid-channel efficiency |
| Customer | refund, return, and complaint rates | expectation or quality gaps |
| Fulfillment | on-time ship and delivery rates | operational reliability |
| Inventory | sell-through, stockouts, and aged units | cash trapped or demand missed |
| Retention | repeat-customer rate | whether value continues |
| Cash | bank cash and near-term obligations | ability to operate |
Define every metric in the sheet. If “revenue” excludes refunds in one platform and includes them in another, comparisons become misleading.
Calculate contribution profit first
For each channel and major product:
Contribution profit = net order revenue – product cost – packaging – fulfillment and shipping subsidy – platform/payment fees – discounts – advertising – variable return allowance
Then subtract monthly overhead to estimate operating profit. A product with a 4 percent conversion rate can still be harmful if ads and fulfillment consume the margin.
Compare three ways
Compare this month with last month, the same month last year when seasonality matters, and your plan. Then break significant changes by channel, device, product, country, and new versus returning customer.
Do not react to tiny samples. One return among ten orders is 10 percent. One more makes it 20 percent. Read the underlying cases before declaring a trend.
Add operational warning thresholds
Choose a trigger and owner for each important number. Examples:
- contribution margin falls below your product floor.
- on-time shipping drops below your service promise.
- one SKU's return rate doubles with at least a meaningful order count.
- stock cover falls below supplier lead time plus safety stock.
- cash cannot cover the next inventory payment and fixed bills.
Amazon's inventory-management guide explains how too much inventory ties up resources while too little can miss demand. Shopify's analytics documentation describes available reports for its platform. Export the underlying data when dashboard definitions do not answer your question.
Finish the meeting with three sentences: what changed, why you think it changed, and what single action will test that explanation. A dashboard without a decision is decoration. The U.S. Small Business Administration's financial-management overview also points owners toward bookkeeping, balance sheets, and cash-flow projections, which belong beside storefront analytics.
