MarginOS for Agencies
& Growth Partners

Help your Shopify DTC clients stop chasing revenue and start commanding profit. MarginOS gives you a Profit & Inventory OS you can plug into each client so you can prove impact, retain longer, and add a high‑margin analytics layer without building it yourself.

  • Move conversations from ROAS to contribution, payback, and inventory reality
  • Show exactly which SKUs and channels are making or losing money
  • Stay in the room as a strategic partner, not a replaceable media buyer

Why agencies lose great clients

Most DTC agencies get blamed for problems they can’t see or control:

  • Clients judge you on ROAS and top‑line while their margin and cashflow are broken
  • Downstream data lives in Shopify, 3PLs, and spreadsheets, so you’re flying blind past the ad platform
  • You get fired when the client is “unprofitable”, even if your campaigns are working
  • Founders ask “What should we scale, pause, or fix?” and all you can show is channel dashboards

MarginOS gives you and your clients a shared profit source of truth so you can move the conversation from “ROAS” to “contribution and payback” and stay in the room as a strategic partner.

Turn dashboards into decisions for your clients

For each Shopify client, MarginOS gives you:

Profit & Inventory Command Center

A live snapshot of revenue, true margin, customer economics, and inventory health, plus “Top Moves” and “Biggest Risks.”

Use it in QBRs and weekly calls to:

  • Show what changed and why it matters
  • Highlight which product families and channels to scale, protect, or fix
  • Anchor discussions in profit and weeks of cover, not just ROAS

Growth Engine

A portfolio view by product family × channel, ranked by contribution profit and CAC payback, with weeks of cover beside performance.

Use it to:

  • Explain why some “winning” campaigns are secretly destroying margin
  • Align ad spend with inventory reality so you don’t scale into stockouts
  • Show founders exactly where to push, hold, or cut

Catalog Profit (Yield Engine)

A SKU‑level profit and data health workspace.

Use it to:

  • Uncover bad or missing cost data that make ROAS‑based decisions dangerous
  • Highlight “problem SKUs” with high returns or low margins that cap what marketing can do
  • Partner with the client to fix economics before you get blamed for performance

Plan Engine

Turn hand‑wavy goals into a clear, profit‑aware plan.

Use it to:

  • Help clients set product‑ and channel‑level targets by family / SKU
  • Run plan vs actual in the same view as profit and inventory
  • Reallocate spend to hit plan instead of reacting to last week’s ROAS
Beta

Replenish Engine

Predictive reorder cohorts for repeat‑purchase brands.

Use it to:

  • Find “likely to reorder” customers by product
  • Time email/SMS nudges so you grow repeat revenue without cannibalizing natural demand
  • Bring proactive lifecycle ideas backed by profit, not guesswork

How agencies use MarginOS in practice

For each DTC client on Shopify, you:

1

Connect the data

Connect Shopify, Google Ads, Meta Ads, and 3PL / cost files with our guided help.

2

Let MarginOS build the profit model

MarginOS ingests the last 90 days and builds the client’s Profit & Inventory Command Center, Growth Engine, and Yield Engine.

3

Run reviews from one source of truth

Use MarginOS as the backbone for weekly performance reviews, monthly / quarterly strategy calls, and board‑level reporting.

Instead of defending ROAS, you’re walking the founder through profit‑based decisions: what to scale, what to cut, and which products are structurally broken.
