A lot of Shopify retailers are doing turnover, but end up with A ridiculous margin.
Why? Because they can't see where the money escapes.

Between Shopify fees, logistics, apps, apps, promotions and acquisition costs... your margin can melt without you noticing it.

👉 The good news: in 90% of cases, these are always the same 3 mistakes.

Here they are.

Mistake 1: Thinking that “free” delivery is really free

Free delivery has become a standard...
But poorly managed, it is The number one way to kill your margin.

❌ Common mistakes:

• Offer delivery on ALL orders (even at 20€...)
• Do not adjust rates according to weight/country
• Absorb product returns without conditions

👉 Result: you pay 3 to 12€ by command... silently.

✅ The solution:

• Put a smart threshold : “Free delivery from 60€”
• Integrate logistics costs into the Product price
• Negotiate with carriers or use 3PLs
• Suggest a upgrade (paid express delivery)

💡 Tip:
Amazon never REALLY offers delivery...
They incorporate it into the prices + the Prime subscription.

Mistake #2: Underestimating Shopify fees... and its apps

Shopify is simple.
But Shopify + apps + payments = time bomb.

✅ Real example:

• Shopify Plan: €29/month → OK
• Apps: 6 apps at €20 → €120/month
• Shopify Payments: 2.9% + €0.25 per transaction
• Emailing platform: 50€/month
• Currency conversion fees: 1.5%...

Total = 300 to 500€ per month + 3 to 5% of turnover... without realizing it.

✅ The solution:

• Audit your apps once a month (remove redundant ones)
• Negotiate plans (pro apps = better margins)
• Limit heavy visual apps (slow down the site AND are expensive)
• Compare payment providers

💡 The most profitable brands use FEWER apps... but better chosen ones.

Mistake #3: Making promotions that destroy your margin instead of increasing it

“— 20% discount”
“Black Friday at -40%”
“Buy 2 = get 2 free”

👉 It boosts turnover...
👉... but It's spraying the margin.

❌ Classic mistakes:

• Generalized promotions instead of targeted ones
• Discounts on the most marginalized products (kill them)
• No analysis of product cost + logistics + ads

The result: you think you're winning... you're losing.

✅ The solution:

• Make some bundles (packs) → better margin than discount
• Upsell/cross-sell instead of reducing the price
• Offer a gift with low perceived high cost
• Segmenting promotions (VIPs, new customers...)

💡 The best brands increase their margin during the promotions (thanks to higher baskets and scale effects).

BONUS: The worst mistake of all...

Do not monitor cash flow and margins in real time.

You can do:

• 100k€ in turnover
• ... and be in Danger of bankruptcy if the cash comes out faster than it comes in.

👉 The best e-retailers don't drive sales.
They fly at:
✅ The actual margin per product
✅ Profitability per channel
✅ Cash available
✅ The LTV/CAC
