Why Your Analytics Will Fail in 6 Months: 3 Ways to Build E-commerce Analytics

Why Will Your Analytics Stop Working in 6 Months?

The story of every e-commerce business starts innocently. In the beginning, there is one online store. An order panel in a system like Magento, Shoper, or Idosell is enough for you. Everything is clear – you have access to basic information about revenue, customers, and products.

But then you start to grow.

You connect Google Analytics 4 to understand user behavior. You launch campaigns in Google Ads, Meta Ads, TikTok Ads, and Criteo to drive traffic. You enter Allegro (Marketplace) to increase reach. You start cooperating with price comparison engines (Ceneo) and affiliate networks.

Finally, you make the decision: "We are entering foreign markets." You open sales in the Czech Republic, Germany, or Romania.

And at this moment, the scale of the problem explodes. You now have separate ad accounts for each country, reports in different currencies (PLN, EUR, CZK, RON), and separate product feeds. You wake up in a world where data is in thirty different places. The Facebook panel shows different conversions than GA4, the store's CRM doesn't see costs from Romania, and calculating margins takes two days in Excel.

Instead of clarity, you have chaos.

You then face a choice: how to "build a home" for your data to get it under control? In the world of analytics, you have three paths. Two of them are traps that look tempting at the start but collapse like a house of cards when your company begins to scale.

Here is a story about analytical maturity – based on the old fable of the three little pigs, but with a very modern (and painful) moral.

Path 1: The "Black Box" Trap (The House of Straw)

The first path is chosen by pragmatists who want results "right now." You choose ready-made, closed reporting systems (so-called black boxes).

  • What does it look like? You connect an account, pay a subscription, and see nice charts. It is fast and painless.
  • Where is the problem? This solution works until you ask a difficult question. You see metrics (e.g., ROAS), but you have no idea how they were calculated. You do not have access to the raw data underlying that result.

What happens when Growing Requirements (The Wolf) come?

One day your company grows, and you need to do something more with the data than just look at it. That's when you start hitting wall after wall:

  1. The "Main Report" Wall: The board uses Power BI or Tableau. You want to add marketing costs from your "black box" there to see the full business bill. Reality: It’s impossible. You are in a closed ecosystem. You are left with manually pasting CSVs into Excel every Monday.
  2. The "CRM Automation" Wall: Your sales team wants to see in the CRM which ads a lead clicked on. Reality: Your "black box" has no API or it is very limited. You cannot "feed" the sales department with marketing knowledge.
  3. The "AI Partners" Wall: You hire an AI agency that asks for historical transactional data to train its algorithms. Reality: There is no way to securely share a slice of the data.

The Finale: You hire a great analyst. They want to build their own attribution model on raw data. The "black box" provider says: "Of course, we share raw data in the Enterprise plan, which costs 5 times more." Your data has become a hostage.

Path 2: The Illusion of Control, or "Do It Yourself" (The House of Sticks)

The second path is for the clever ones. You think: "I won't let them lock me in a box! We'll do it ourselves in-house. We have free connectors and Greg in IT." This is the DIY approach, which usually ends in chaos in two acts:

Act I: The Connector Frankenstein in Looker Studio You connect separate plugins directly to Looker Studio: Facebook Ads, Google Ads, GA4, CRM.

  • Problem: These are silos. To see the whole picture (e.g., profit vs. spend), you have to force-combine these sources in the visualization tool (Blended Data).
  • Risk: The business logic is "sewn" into fragile report filters, not the database. One error in campaign naming is enough for the entire report to stop working.

Act II: The Swamp of Raw Data (ETL without a plan) You go a step further. You dump data into your own BigQuery using simple ETL tools.

  • Problem: You have access to data, but it is a so-called "Data Swamp." You have 800 tables: orders separately, products separately, campaigns separately. Nothing matches anything else.
  • Risk: To use this, someone must write and maintain complicated SQL logic.

What happens when "Greg" leaves? This whole structure holds together only thanks to the one person who built it. When "Greg" leaves the company, he takes the knowledge with him. You are left with infrastructure that no one understands. A new analyst, instead of looking for insights, wastes months on reverse engineering, trying to understand why the numbers don't add up.

Path 3: The WitCloud Foundation (The House of Brick)

The third path is for those who understand that analytics is an investment in company assets. You choose WitCloud (All In One).

Why is this the house of brick? Because it combines the advantages of both worlds while eliminating their disadvantages.

First: Automating the "Dirty Work" WitCloud is a platform that does the heavy engineering work for you. Our module automatically downloads, cleans, and unifies data from over a dozen systems (Ads, GA4, CRM, Marketplaces). You don't worry about changes in the Facebook or TikTok API – we take care of maintaining this infrastructure. Your technical team sleeps soundly.

Second: Visualization at the Start + Openness to Growth We don't leave you with just a database. You receive a set of base reports in Looker Studio. For many companies, this is enough to make decisions "here and now." But what if your appetite grows? Because the data is your property and sits on your Google Cloud, you have full freedom:

  • You can develop reports yourself.
  • You can commission us to build dedicated dashboards.
  • You can collaborate with any agency that knows SQL/BigQuery. No one needs to learn "our system" – they work on Google standards.

Third: An Analyst's Paradise When you hire an analyst, you don't give them a "black box" or a "swamp of 800 tables." You give them access to ready-made, documented datamarts (e.g., for margin analysis or custom attribution models). The analyst can write their own SQL queries or plug data into AI tools. You pay an expert for insights (high value), not for "data cleaning" (low value).

Moral: From Fighting Tools to Using Data

Analytical maturity is the moment when you stop fighting with tools and start using data.

Don't build with straw (because lack of access or Enterprise costs will limit you). Don't build with sticks (because you will drown in technical debt when your "Greg" leaves and you enter another market).

Build a foundation with WitCloud. Thanks to this, regardless of whether you have one marketer today or an international Business Intelligence department in a year – your analytical environment will be ready, secure, and scalable. And you will be the owner of the truth about your business.
