Seller Profit Doctor

For Shopify stores

Where a Shopify store’s money goes, and how to keep more of it.

On Shopify the money goes to your plan, card fees, labels, product cost and ads. The free check-up asks about each in Shopify’s own words, shows what each order keeps, and gives each loss a fix with what it’s worth at your numbers, if orders hold.

What the check-up asks

Eight short screens, and a ninth if you run ads. Your plan and how card payments reach you are in Settings. Your best guess is fine.

  1. About how many orders do you get in a typical month?

    Analytics > Orders.

  2. What does a typical order come to, before shipping and tax?

    Your average order value is fine.

  3. What do the products in that order cost you?

    Product cost, also called COGS.

  4. Shipping on a typical order.

    Label costs: your last shipping label is fine.

  5. Which Shopify plan are you on, and how do you pay for it?

    Settings > Plan.

  6. How do card payments reach you?

    Settings > Payments.

  7. About how much do you spend on ads a month (Meta, Google, TikTok)?

    Your best guess is fine.

  8. For every $1 on ads, about how much in sales comes back?

    Only if you run ads. Use your Shopify sales, not the number in Ads Manager.

The losses it looks for

Each check runs on your answers. Where it finds a loss, the result gives its dollars a month and the fix.

  • Shipping gap

    The fix: Put the gap into your prices, or charge buyers what shipping really costs.

  • Ads that don't pay back

    If you run ads

    The fix: Pause campaigns below your break-even ROAS, worked out from what each order keeps.

  • Third-party processor fee

    If another card company takes your payments

    The fix: Run your cards through Shopify Payments, where Shopify adds no third-party fee.

  • 1.25% for mixing card processors

    If you use two

    The fix: Use one card processor.

  • Plan fit

    The fix: Move to the plan that costs least at your card sales: Basic, Grow or Advanced.

  • Paying for your plan monthly

    The fix: Switch to yearly billing, which costs less a month.

  • Price below landed cost

    The fix: Raise prices until they cover product cost, shipping, card fees, refunds and ads.

The paid reports ask a few more questions and check the smaller losses too. Every fix’s value assumes your orders hold, and a risk line says how far they could fall before the fix leaves you worse off.
