What gets checked

Fees and reimbursements

Referral and FBA fee accuracy, size tier errors, lost and damaged inventory you can still claim.

True SKU margin

Landed cost, fees, returns, ad spend and storage per SKU, so you can see which products actually make money.

Inventory health

Stockout risk, aged stock, long-term storage exposure and reorder points.

Ad spend

TACoS by SKU, wasted search terms and campaigns spending on unprofitable products.

Returns and refunds

Return rates and reasons by SKU, refund leakage and listing fixes that reduce returns.

Shopify checkout and shipping

Shipping charged versus paid, discount leakage and payment fee mix.

Sample report extract

Illustrative example. The brand and numbers are invented to show the format; this is not a client.

Summary. Revenue $212,400. Reported contribution margin 21%. After allocating returns, storage and ad spend per SKU, true contribution margin is 14.2%. Seven SKUs lose money on every sale. The fixes below are worth an estimated $41,000 a year.

FAQ

Who is this for?

Brands doing roughly $20k to $500k a month on Amazon and/or Shopify that don't have a full-time ops or finance person.

Do you implement the fixes?

The report tells you exactly what to change and in what order. Most fixes take your team under an hour each. If you want help implementing them, that can be quoted separately.

Is my data safe?

Access is read-only and you can remove it as soon as the report is delivered. Data is used only for your audit and is never shared.

What if I only sell on one channel?

That's fine. The price is the same and the report covers whichever channels you sell on.

Why 72 hours?

The work is structured and repeatable. The clock starts once access is in place.
