When it comes to scaling an e-commerce or product-based business, few tools are as powerful as a custom SKU profitability dashboard. The idea is simple: track exactly how much money you make (or lose) on each individual product SKU, so you can make smarter decisions about pricing, inventory, marketing, and operations.

Yet in working with brands of all sizes through our new venture, Modonix, we consistently see the same mistakes. Businesses want to be data-driven, but their dashboards are either too shallow, too complicated, or completely disconnected from what actually drives profit.

If you’re planning to build—or rebuild—your custom SKU profitability dashboard, here are the most common pitfalls to avoid and how to approach it the right way.

Mistake #1: Focusing on Revenue Instead of Net Profit

Many brands mistakenly track SKU-level revenue instead of net profit. But revenue is just the top line. A SKU generating $80,000 a month in sales might be unprofitable once you factor in advertising, shipping, returns, and Amazon fees.

What to Track Instead:

  • Unit Cost (COGS)

  • Advertising Spend (per SKU)

  • Amazon/Marketplace Fees

  • Shipping & Fulfillment

  • Refunds & Returns

  • Storage or Handling Fees

  • Net Profit (Revenue – Total Costs)

  • Gross Margin %

A true SKU profitability dashboard tells you not what’s selling, but what’s working.

Mistake #2: Overengineering Before You Validate

We’ve seen brands hire developers or agencies to build complicated dashboards in Power BI or Tableau before they even know what KPIs they truly need. The result? A beautiful dashboard that no one uses.

The Smarter Approach:

Start in Google Sheets or Looker Studio with real SKU data. Focus on building:

  • Basic P&L per SKU

  • Channel-specific breakdowns

  • Manual input columns for ad spend, fees, or anomalies

Once your reporting logic is solid, then automate it using Google Analytics, Amazon Seller Central reports, or integrations from tools like Supermetrics, Data Connector, or Zapier.

Mistake #3: No Attribution of Ad Spend Per SKU

If you’re running Performance Max, Meta Ads, Amazon Sponsored Products, or any paid campaigns, then ad spend must be attributed at the SKU level. Too often, brands lump all ad costs into a single bucket.

What to Do:

  • Use UTMs and feed-based tracking (for Google/Merchant Center)

  • Use Amazon’s Search Term Impression Share + ACoS to approximate per-SKU spend

  • Break ad spend into product groups

This allows you to answer: “Is this SKU still profitable after paid acquisition?”

Mistake #4: Treating Every SKU Equally

Not all products serve the same purpose in your catalog. Some are high-margin flagships, some are bundling items, and others are seasonal or clearance.

Add Context:

  • Label SKUs by role (Hero, Add-on, Clearance)

  • Create columns for Lifetime Value (LTV), Repeat Purchase Rate

  • Color-code or tag priority SKUs

This allows your team to focus on scalable, profitable products rather than just top sellers.

Mistake #5: No Operational Rhythm Around the Dashboard

The biggest mistake of all? Building a dashboard and then letting it sit idle.

A dashboard is only useful if it’s being reviewed regularly and driving action.

Embed It Into Weekly or Monthly Routines:

  • Weekly marketing review: Check top 10 profitable SKUs

  • Monthly finance ops: Kill low-margin SKUs

  • Inventory planning: Align reorders with margin insights

At Modonix, we help brands not just build dashboards, but install operational rhythms so data turns into real decisions.
