How can a buyer tell whether ecommerce growth is durable?

Answer: Durable ecommerce growth does not depend on one temporary source of demand, one marketplace, one promotion, or continuously rising advertising spend. Boards should look for stable or improving contribution, repeat demand, healthy inventory productivity, diversified acquisition sources and evidence that customers value the product independent of paid placement. Growth can still be concentrated and durable, but management should be able to explain why the economics persist and which assumptions would fail first if market conditions change.

Why this matters

Growth multiples depend on confidence that today’s performance can continue. Fragile growth often reveals itself first through deteriorating economics or rising dependency.

What the board should examine

  • Organic versus paid demand
  • Repeat purchase and retention where relevant
  • Contribution on incremental revenue
  • Platform and SKU concentration
  • Inventory turns and service levels
  • Growth after promotional activity normalizes

What good looks like

The company can identify the drivers of growth, measure their economics, and show that performance does not require progressively more capital or risk to sustain.
