5-Step Ecommerce Margin Audit Checklist

This checklist is built for ecommerce operators who need clear profitability decisions from periodic data exports. MarginVisibility uses two required inputs, sales and inventory, plus an optional cost file to deepen margin precision. The goal is not to produce another dashboard vanity view. The goal is to make weekly decisions that protect gross profit and free trapped cash.

Step one is file readiness. Confirm the two required CSV files are recent and complete, then include cost data when available. Step two is validation. Confirm field mappings, date range consistency, and SKU overlap so your analysis compares like with like. Step three is contribution ranking. Sort by profit contribution instead of top-line revenue to reveal where the business actually earns money. Step four is risk detection. Mark margin killers and dead stock candidates before planning replenishment. Step five is action. Convert insight into a short execution list for pricing updates, reorder controls, and liquidation strategy.

When this process runs consistently, teams spend less time debating reports and more time acting on evidence. It is especially effective for stores that sell across Shopify, Amazon, Etsy, or WooCommerce and need one repeatable method that works from exports.
