Business Data, No Idea How to Work With It<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>At <a href=\"https:\/\/www.nanospace.cz\" target=\"_blank\" rel=\"noopener\"><strong>nanoSPACE<\/strong><\/a>, our entire company is stitched together from dozens of separate tools \u2014 we don&#8217;t have a centralised system (like an ERP) running the show. <strong>This patchwork approach works well, handling tens of thousands of orders per month at a fraction of the cost of heavyweight solutions, but it comes with its own headaches.<\/strong><\/p>\n\n\n\n<p><strong>The biggest one is data fragmentation.<\/strong> Orders land in Shoptet, returns go into Retino, email campaigns are sent via <a class=\"thirstylink\" rel=\"nofollow\" target=\"_blank\" title=\"Ecomail\" href=\"https:\/\/loudavymkrokem.cz\/en\/doporucujeme\/ecomail\/\" data-shortcode=\"true\">Ecomail<\/a>, accounting documents flow into Flexibee, Amazon is managed through Expando, project management runs through <a href=\"https:\/\/loudavymkrokem.cz\/en\/freelo-review-project-management-tool\/\"><strong>Freelo<\/strong><\/a>, B2B orders are split between Shoptet and direct invoicing\u2026 I could keep going for a while.<\/p>\n\n\n\n<p>And that&#8217;s without mentioning that <strong>Shoptet has no suitable module for deeper analysis of order or customer data<\/strong> \u2014 we can forget about RFM analysis entirely.<\/p>\n\n\n\n<p><strong>All of this makes evaluating overall company performance incredibly difficult<\/strong>, and it&#8217;s led to us having at least a hundred Excel and Google Sheets files where we track various performance metrics separately, then painstakingly try to connect the dots.<\/p>\n\n\n\n<p>After the last COVID wave, when things calmed down a bit, I had more time for analytics and started digging deeper into various reports, including:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Revenue \/ profit per marketing channel, adjusted for returns and refunds<\/li>\n\n\n\n<li>Tracking margin trends over time, down to individual product level<\/li>\n\n\n\n<li>Automated allocation of discount coupons and performance tracking<\/li>\n\n\n\n<li>RFM analysis, customer segmentation, cohorts\n<ul class=\"wp-block-list\">\n<li>Identifying traffic builders, etc.<\/li>\n<\/ul>\n<\/li>\n\n\n\n<li>Financial analysis, cost breakdown, cash flow monitoring and forecasting (e.g. automatically calculating the value of delivered but not yet paid cash-on-delivery orders)<\/li>\n<\/ul>\n\n\n\n<p><strong>Every single report meant hours of exporting and merging mismatched data in Excel \u2014 and even then, I couldn&#8217;t fully trust the results.<\/strong> I knew there was a proper way to build this from the ground up: connect data from all systems, clean out outliers, and report into PowerBI or Looker. <strong>But how on earth do you actually do that?<\/strong><\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Business_Intelligence_Running_a_Company_Based_on_Data\"><\/span>Business Intelligence: Running a Company Based on Data<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>Right around that time, an invitation landed in my inbox for a data training course called <a href=\"https:\/\/academy.taste.cz\/posunte-svou-datovou-analyzu-za-hranice-excelu\" target=\"_blank\" rel=\"noreferrer noopener\"><strong>Take Your Data Analysis Beyond Excel<\/strong><\/a>. The course promised I&#8217;d finally learn how to bring order to my business, marketing, customer, and financial data. So off I went \ud83d\ude0e<\/p>\n\n\n\n<p><strong>The training was spot-on for me!<\/strong> I&#8217;m not a complete data novice \u2014 we already have our own data warehouse, and we&#8217;d already built a few custom reports with <a href=\"https:\/\/digitalniarchitekti.cz\" target=\"_blank\" rel=\"noreferrer noopener\"><strong>Digit\u00e1ln\u00ed architekti<\/strong><\/a>. What I was missing was the bigger picture: an overview of what&#8217;s actually possible with the data flowing through our systems. And that&#8217;s exactly what I got from the course.<\/p>\n\n\n\n<p>The training is led by <a href=\"https:\/\/academy.taste.cz\/premysl-horacek\" target=\"_blank\" rel=\"noreferrer noopener\"><strong>P\u0159emek Hor\u00e1\u010dek<\/strong><\/a>, a seasoned Business Intelligence specialist. He makes a living connecting data sources for companies and uncovering the relationships hidden within them, helping his clients shift from gut-feeling decisions to data-driven management.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Keboola_A_Data_Extractor_for_Any_System\"><\/span>Keboola: A Data Extractor for Any System<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>If I could take away just one thing from the training, it would be this: <strong>sign up for Keboola<\/strong>! Keboola is the tool I&#8217;d been searching for. It allows you to regularly pull data from virtually any source. Here&#8217;s what I connected:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Google Analytics<\/li>\n\n\n\n<li>Google Ads<\/li>\n\n\n\n<li>Facebook Ads<\/li>\n\n\n\n<li>Sklik<\/li>\n\n\n\n<li>Shoptet<\/li>\n\n\n\n<li>Flexibee<\/li>\n\n\n\n<li><a class=\"thirstylink\" rel=\"nofollow\" target=\"_blank\" title=\"Marketing Miner\" href=\"https:\/\/loudavymkrokem.cz\/en\/doporucujeme\/marketing-miner\/\" data-shortcode=\"true\">Marketing Miner<\/a><\/li>\n\n\n\n<li>Google Sheets<\/li>\n<\/ul>\n\n\n\n<p>Keboola connects to each source via API and pulls the data you need.<\/p>\n\n\n\n<p>Once inside Keboola, you can transform the data (using SQL or R \u2014 P\u0159emek covers the basics during the training) and then save or export it to a storage solution. I export to Google BigQuery, but Google Sheets works too.<\/p>\n\n\n\n<p><em>Transformations might include cleaning out extreme values (removing test orders, one-off orders worth \u20ac20,000, etc.), joining data from different tables using a shared ID, or any other manipulation your dataset needs.<\/em><\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"What_can_you_use_it_for\"><\/span><strong>What can you use it for?<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>For preparing data for virtually any report you can imagine. Here&#8217;s what I&#8217;ve done or have planned:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Cleaning ad platform data by removing cancelled \/ returned orders<\/li>\n\n\n\n<li>Building an automated coupon report that calculates actual discounts given and resulting margins<\/li>\n\n\n\n<li>Calculating margins per order and bucketing them (grouping orders by size \/ profitability)<\/li>\n\n\n\n<li>RFM analysis on customer data pulled from Shoptet<\/li>\n\n\n\n<li>A cash flow dashboard enriched with cash-on-delivery data<\/li>\n<\/ul>\n\n\n\n<p><em>The training also covers Google BigQuery, a similar tool for data extraction and transformation. It may be better suited for certain use cases, but it&#8217;s not as intuitive for the average user.<\/em><\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"How_do_you_transform_the_data\"><\/span><strong>How do you transform the data?<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p><strong>Unfortunately, there&#8217;s no avoiding a bit of coding.<\/strong> Big data means big tables, so you&#8217;ll need at least basic SQL or R skills. Both are covered during the training, and afterwards we received a handy cheat sheet of essential commands. I have no ambition to master these languages in depth, but thanks to the course I now have enough understanding to know what to ask our data analysts for \u2014 and what&#8217;s realistic.<\/p>\n\n\n\n<p><strong>Keboola is also preparing templates for easy data extraction.<\/strong> This feature is still in beta, but it already offers several basic schemas for merging data from ad platforms and sending it to Google Sheets or PowerBI. <strong>For the most common use cases, you won&#8217;t need any coding at all in the near future.<\/strong><\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"How_to_Visualise_Your_Data\"><\/span><strong>How to Visualise Your Data?<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>Once your data is prepped, you&#8217;ll want to visualise it \u2014 that&#8217;s the whole point, after all. Marketers will likely know Looker (formerly Google Data Studio), which I use extensively for all sorts of marketing reports.<\/p>\n\n\n\n<p>What impressed me more, though, was PowerBI, which I&#8217;d successfully ignored until now (mostly because it doesn&#8217;t run natively on Mac \ud83d\ude0e). After the training, I realised that Looker is essentially a demo version of PowerBI. While both platforms are constantly converging, PowerBI still has the edge.<\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img decoding=\"async\" src=\"https:\/\/www.loudavymkrokem.cz\/wp-content\/uploads\/2023\/05\/bc-hospodareni-spolecnosti.png\" alt=\"Example of data visualisation in PowerBI\" class=\"wp-image-58411\" title=\"\"><figcaption class=\"wp-element-caption\">Example of data visualisation in PowerBI<\/figcaption><\/figure>\n<\/div>\n\n\n<p>I spent a total of 8 hours at the data training, and I consider it a solid investment.
