Marketplace brands

For brands selling across marketplaces and DTC

Selling on Amazon, Walmart, and your own store means three sets of numbers that never agree. We build the layer that reconciles them into true profitability by SKU and channel, with ad spend, fees, and returns all accounted for.

Quick answer

Data infrastructure for brands selling across Amazon, Walmart, and DTC: true profitability by SKU, unified channel reporting, and inventory-aware ad decisions.

Revenue is easy, profit is the mystery

Marketplace revenue is straightforward to read. Profit is not. Amazon fees arrive across referral, FBA, storage, and long-term storage lines that only reconcile in settlement reports. Returns land weeks after the sale that earned the bonus. Ad spend sits in a separate system from the sales it drove. So decisions get made on ROAS, which ignores fees and returns entirely, and brands scale SKUs that lose money at volume.

What we build for brands

  • Unified sales and cost data across Amazon, Walmart, other marketplaces, and your DTC store
  • True profitability by SKU and channel: COGS, all marketplace fees, ad spend, returns, and shipping
  • Settlement reconciliation so reported profit matches the money that actually arrived
  • Inventory and demand visibility joined to advertising, so spend is not pushed into a stockout
  • Channel comparison on contribution margin rather than revenue or ROAS
  • Reporting your operators and your finance team both accept as correct

How we work

  1. Start with one marketplace and get true SKU profitability genuinely correct there

  2. Reconcile against settlement reports and finance until the numbers are accepted

  3. Add remaining channels and DTC onto the same model

  4. Layer inventory-aware advertising decisions once profitability is trusted

Frequently asked questions

Because they each see one channel and none of them see your costs. Amazon knows its own fees but not your COGS, your DTC margin, or your Walmart performance. True profitability requires joining marketplace data to your cost data, which only happens outside the platforms.

By modeling on settlement data rather than order data, with a maturity window so recent periods are marked as provisional. Returns get attributed back to the period of the original sale. Without that, recent performance always looks better than it turns out to be, which is how overspending happens.

No. Most brands we work with have no data engineers, which is why the output is reporting your existing operators and finance team can use directly rather than a platform requiring someone to run it.

Yes, and it is one of the highest-value pieces. Joining advertising to inventory position stops you spending into a stockout, and stops you suppressing spend on a SKU with excess stock. Both mistakes are common and both are expensive.
