Scaling ecommerce sales before checking margin can turn a promising campaign into a cash problem.
The first mistake is reviewing ROAS without order profit. A campaign can show strong revenue while product cost, shipping, fees, returns, and ad cost leave little profit.
The second mistake is using average margin for every product. If one product has a much lower margin, it can absorb more ad spend and discounts than expected.
The third mistake is ignoring small fixed or per-order costs. Packaging, payment fees, app fees, and fulfillment add up when volume increases.
