What's Inside
Build the margin waterfall before chasing growth
Start with the net revenue you actually keep. Subtract discounts, promotions, distributor or retailer deductions, and chargebacks before you call the remainder margin. Then work down through product, packaging, freight, warehousing, and fulfillment.
The useful unit is not always the SKU. For a multi-channel brand, calculate margin by SKU and channel. A product can be healthy DTC and unattractive in wholesale once freight, commissions, and retailer requirements are included.
The five places margin usually leaks
Product cost
Small formula, material, or MOQ changes compound quickly. Track cost by current quote and by landed unit—not by an old purchase order.
Packaging and freight
Dimensional weight, case configuration, breakage, and expedited shipments can erase a good product margin.
Channel deductions
Chargebacks, promotions, broker commissions, distributor fees, and payment terms need a place in the model before the launch.
Inventory decisions
Excess inventory turns cash into storage and markdown risk. Stockouts turn margin into missed demand and rushed freight.
Operational rework
Every relabel, partial shipment, failed inspection, and manual correction has a cost. If it happens repeatedly, it belongs in the margin conversation.
Turn the analysis into decisions
Set a floor
Define the minimum contribution margin each channel and SKU must produce after variable costs. Make exceptions visible.
Rank the leaks
Quantify the biggest losses first. Do not spend a month negotiating a small packaging saving while expedited freight is eating the quarter.
Model the tradeoffs
Test MOQ, price, case pack, freight mode, and promotion scenarios. Show the volume required to make each option work.
Assign owners and dates
A margin model without an action owner is a report. Put every improvement into the same operating rhythm as inventory and production.
What founders and investors should see
A useful margin dashboard explains movement. Show gross margin by channel, landed cost by SKU, top deductions, freight variance, inventory exposure, and the actions underway.
Avoid a single blended margin number that hides an unprofitable channel. Clarity is more valuable than a flattering average.
Operator rule. Never approve growth that you have not modeled at the unit level. More orders do not fix bad economics.
