eCommerce · Bookkeeping + Controllership

From blended margins to SKU-level profitability

A controller-led margin rebuild made channel and SKU profitability visible—so the owner could stop funding loss-making products.

The operating change

One finance system replaced an incomplete view.

Gross margin improved from 34% to 45% in two months after the finance system exposed three unprofitable SKUs.

The challenge

What was missing

Revenue and COGS were blended. No one could see whether a product, channel, or campaign was producing profit.

What TMA built

Foundation before decisions

  1. 01Rebuilt the chart of accounts for SKU-level COGS
  2. 02Created Shopify and Amazon channel P&Ls
  3. 03Added controller review to the monthly close
The statement

See the operating difference.

Each view is intentionally compact: the lines a founder or operator should be able to use in a decision conversation.
