The problem

Revenue is growing. So why isn't the money showing up?

  • Your Shopify dashboard shows sales.
  • Your ad platforms show ROAS.
  • Your 3PL sends invoices.
  • Your inventory system shows stock.
  • Your spreadsheet tries to combine everything.

But none of them answer the questions that actually matter:

  • Which products are worth scaling after every cost?
  • Which channels bring profitable customers, not just revenue?
  • Which SKUs are quietly losing money through shipping, fulfillment, discounts, or returns?
  • How much cash is trapped in slow-moving inventory?
  • Which customers are worth protecting, reactivating, or excluding?
  • What should your team fix this week?

MarginOS connects the numbers and turns them into decisions.

The outcome

Stop managing revenue. Start managing profit.

MarginOS gives your team one trusted view of:

  • Profit by SKU and channel
  • Fulfillment, shipping, payment, refund, and return costs
  • CAC payback and lifetime gross profit
  • Weeks of cover and cash tied up in inventory
  • Product and customer profitability
  • Plan versus actual performance
  • The highest-impact actions to take next

Who it is for

Built for brands that have outgrown simple profit tracking.

If you are under 1,000 orders per month and pack every order yourself, a simpler tool may be enough.

MarginOS is for you if:

  • You run a Shopify DTC brand doing roughly $2M to $20M annually
  • You process enough orders that fulfillment costs materially affect margin
  • You use a 3PL or warehouse team
  • You run paid media
  • You sell across multiple products or business lines
  • Your revenue looks healthy but profit is harder to explain
  • You want decisions, not another dashboard

Secure. Compliant. Trustworthy.
