What each unit actually earns, on each channel, after everything

Contribution margin per SKU and per channel: price, platform fees, fulfilment, storage, returns, advertising and the cost of the goods, built into one model you can act on. It is how pricing, advertising and stock decisions stop being guesses.

What’s included in Unit Economics

The contribution margin model

Every cost between the sale price and the unit's landed cost, per SKU and per channel, from the platform's own fee schedules and your reports rather than estimates.

  • Platform and fulfilment fees
  • Storage, returns and advertising
  • Landed cost
The contribution margin model

Pricing decisions

Where a price change pays and where it only moves rank: the model shows the margin at each price point once fees and advertising move with it.

  • Price points modelled
  • Fee changes reflected
  • Promotion economics
Pricing decisions

Advertising against margin

Which campaigns produce contribution and which buy revenue at a loss, so budgets follow profit rather than the platform's own report of itself.

  • Campaign contribution
  • Break-even ACoS per SKU
  • Budget allocation
Advertising against margin

Channel and catalogue decisions

Which products carry the account, which channel a product should not be on, and what stock and storage decisions cost at the unit level.

  • Channel comparison
  • Catalogue pruning
  • Stock and storage cost
Channel and catalogue decisions

How it works

  1. 1

    Gather the inputs

    Fee schedules, fulfilment and storage rates, returns history, advertising reports and landed costs, per SKU and per channel.

  2. 2

    Build the model

    One contribution margin per unit per channel, with every cost line visible and every assumption named, so nothing in it has to be taken on trust.

  3. 3

    Read it together

    Which products, prices, campaigns and channels are earning and which are not, and the decisions that follow.

  4. 4

    Keep it current

    Fees, costs and advertising change. The model is refreshed on a cadence that suits the account, so the decisions keep being made on today's numbers.
