What Margly Sees in Your Store That You Don't

The problem isn't the data. It's that nobody reads all of it.#

Most store owners today have plenty of data. It's in your store admin, in Google Ads, in Meta Business Suite, in Sklik, on Heureka, in Google Analytics. The problem is that nobody joins this data together and reads it all the way through.

And that's exactly where the profit leaks away. Not in one big disaster you'd spot at a glance, but in dozens of small leaks hiding inside the totals. The "−20 % off everything" coupon that, on a few low-margin products, pushes the sale below cost. The carrier you pay more than you collect from customers. A product on Heureka you've been paying for clicks on for weeks that hasn't brought a single order. A bestseller whose purchase price nobody has updated in a year, so the margin you base decisions on is off.

Each single thing looks small. Together they usually add up to tens or hundreds of thousands a year. And you won't find them by hand — you'd have to go through every product, every campaign, every payment method, and every supplier each week and compare them against each other. Nobody has time for that.

That's a job for a machine. And that's exactly what the Growth Plan in Margly now does.

How the Growth Plan works#

After every sync, Margly goes through your data and runs a set of guardians. Each guardian looks for one specific type of problem or opportunity. When it finds something, it creates a card: a plain-language title, an estimated annual benefit in real cash, two or three sentences explaining it on your own numbers, a priority, and a clear next step.

The crucial part: these numbers aren't AI estimates. They're calculations from your data. The realized loss on a discount is a sum across the units actually sold. The loss on shipping is the difference between the shipping you collect and the carrier invoices. The lost margin from a sold-out bestseller comes from how much of it sold in the same period last year. And when the data for an honest calculation is missing, the guardian would rather stay quiet than show a number you can't trust. One inflated number would undermine trust in all the others — and we can't afford that.

Let's look at everything we now watch.

Advertising: where your budget disappears#

Advertising is the fastest way to burn money, and at the same time the place where losses are hardest to find. The dashboard shows you the campaign's overall result, but not that a placement or a product inside it is dragging the numbers down. Margly now watches:

• Loss-making products on Heureka — items with hundreds of paid clicks and zero orders. A pure hole in the budget you'd never find by hand.
• Loss-making placements on Meta — when Advantage+ spreads budget into placements (like Audience Network) that don't convert for your store.
• The hours when Meta spends but nobody buys — an overnight click budget with not a single purchase.
• Loss-making products on Zboží.cz — per product, where the return on ad spend doesn't even cover the margin.
• Profitable Google campaigns throttled by budget — the one card that tells you "spend more." Exactly the opportunities you overlook, because every tool only ever deals with waste.

Pricing and margins: quiet profit leaks#

Margin is the only thing you're left with at the end. And it's decided in places you don't normally look:

• Discounts below cost — a blanket coupon on low-margin products sells below cost, and you'll never see it in revenue.
• A supplier with systematically worse margin — concrete negotiating ammo: "with this supplier your margin is well below the rest, and you're doing big volume for them."
• Forgotten individual customer discounts — a "loyal customer" discount someone set years ago that nobody has ever reviewed.
• A price cut that didn't lift sales — the fastest margin fix: put the price back, because the data shows the discount didn't bring volume.
• A successful price increase worth repeating — when a price increase went through on one product without a drop in sales, it shows you similar products where you have the same room.
• Products listed on your site below cost — prevention: it catches a price typo before the goods sell out below cost.
• Bestseller purchase prices older than a year — because your whole margin overview is only as accurate as the purchase prices underneath it.

Customers: who you're losing and why#

Winning a new customer costs several times more than keeping an existing one. Margly watches the signals that tell you when something's breaking:

• Failed cash-on-delivery orders — when your cash-on-delivery orders fail far more often than prepaid ones, every order moved to card payment is pure profit (and shipping saved both ways).
• VIP customers falling out of rhythm — based on each customer's personal buying rhythm, not a blanket threshold. Someone who bought every three weeks and has now gone silent for six is at risk.
• A declining return rate of new customers — a drop in how many freshly won customers come back for a second purchase. A signal that only shows up in the overall numbers months later.
• A sudden spike in cancellations — when your cancellations double within a few days, something broke: the payment gateway, shipping, a price after an import.
• Growing demand from abroad — when a specific foreign market grows in orders without any effort on your part, it might be worth adding a language version or a local carrier.

Season and web: opportunities ahead of time#

Some things you have to know in advance, or it's too late:

• Restocking before a seasonal peak — a month ahead, it tells you which bestsellers are at risk of running out this year in the middle of last year's peak. Restocking takes weeks, so the signal has to come in time.
• This month is trailing last year — a seasonally adjusted comparison with the same month last year, not a mechanical drop that sounds the alarm after every season.
• A drop in Google traffic — on the specific pages that lost rankings, before it feeds through to revenue.
• Falling visibility in AI answers — how you stand when customers ask ChatGPT and other assistants, and when your share is dropping.

The more you connect, the more you see#

This is the single most important sentence in the whole article: the guardians only work on the data you connect.

Connecting your store (Shoptet, Shopify, or Upgates) is the foundation — from it Margly derives margins, discounts, inventory, customers, shipping. But the advertising guardians need Google Ads, Meta, Sklik and Zboží.cz, or Heureka connected. The organic-traffic drop needs Search Console. Conversion anomalies need Google Analytics. AI visibility needs the GEO module switched on.

In other words: every system you don't connect is a guardian that won't switch on — and a blind spot where money can disappear without you knowing. Connecting takes a few minutes and happens through the platforms' official integrations. The payback is usually in the first card Margly shows you.

And what Margly does beyond the Growth Plan#

The Growth Plan stands on foundations Margly calculates all the time:

• True net margin — a cascade from revenue through purchase prices, logistics, marketing, and operating costs down to what you actually keep. Not a number from a platform dashboard, but your real profitability.
• Break-even return on ad spend — how much advertising has to return to be worth it at all, calculated from your actual margin.
• AI Advisor — ask about your numbers in plain language and get an answer built on your data, not generic advice.
• Customer lifetime value and customer groups by the month they first bought.
• Shipping balance — how much you actually collect for shipping and cash-on-delivery versus how much you pay the carriers.
• AI search visibility (GEO) — how often assistant answers mention you and who's outpacing you.
• Automatic syncs and goals, where Margly watches whether you're on track.

Try it on your own data#

The best way to find out what you're missing is to let Margly go through your own data. Not a demo, not someone else's example — your store.

Signing up takes a few minutes, and the first 14 days are free, no card required. Connect your store, hook up your ad platforms, and let the Growth Plan show you the first cards. On each one you'll see how much a given thing is costing you — or how much it can bring you — in real cash from your numbers.

Your competitors may already see these things. You don't have to be in the dark anymore. Try Margly free and stop leaving money lying where nobody looks.
