Ecommerce Profit and Finance Review

This lesson helps you: Use a channel profit and cohort quality sheet to compare Google, Meta, SEO, email, and referral by first-order contribution profit, refund rate, support cost, 30/60/90-day repeat margin, and budget action.

Start here if you're new to this series. Then read: "COGS, Shipping, Payment Fees, and Refund Costs".

This lesson helps you: Put product cost, inbound and outbound shipping, payment fees, refunds, return handling, and support credits into true order cost, then use post-refund contribution profit to decide whether an order can scale.

Best after "Channel Profitability and Cohort Quality". Then continue with "SKU Margin and Contribution Profit Analysis".

This lesson helps you: Read margin, returns, discounts, ad cost, inventory coverage, and affordable CPA by SKU and bundle, then build a SKU contribution ladder for scale, maintain, observe, clean up, or pause decisions.

Best after "COGS, Shipping, Payment Fees, and Refund Costs". Then continue with "Weekly Business Review and Variance Routing".

This lesson helps you: Use a WBR variance routing table to turn revenue, gross margin, ad efficiency, conversion rate, inventory, refunds, fulfillment, and email performance into evidence, owner, this-week action, and next-week acceptance.

Best after "SKU Margin and Contribution Profit Analysis". Then continue with "Cash Flow, Inventory, and Ad Spend Rhythm".

This lesson helps you: Use a cash, inventory, and ad-spend rhythm calendar to plan the next four weeks of replenishment payments, payouts, ad spend, refund/dispute reserves, and inventory coverage before scaling budget.

Best after "Weekly Business Review and Variance Routing". Then continue with "DTC Profit Model Basics".

This lesson helps you: Separate revenue, product cost, shipping, payment fees, refunds, ad spend, and fixed costs into one model that explains whether orders actually make money. This lesson provides a Profit model sheet so profit guardrails, contribution profit, and review templates become operating actions.

Best after "Cash Flow, Inventory, and Ad Spend Rhythm". Then continue with "Promotion, Discount, and Offer Profit Guardrails".

This lesson helps you: Build an offer profit guardrail matrix for welcome offers, free-shipping thresholds, bundles, discount codes, and sale prices, with minimum contribution profit, maximum discount, stacking rules, stop signals, and review ownership.

Best after "DTC Profit Model Basics". Then continue with "Monthly Finance Review and Decision Rules".

This lesson helps you: Use a monthly finance rulebook to turn profit, cash, inventory, channel, SKU, offer, and cohort quality into next-month rules to continue, scale, reduce, pause, or renegotiate cost.
