The website is ready - now I need a shop - how do I go about it?

Sometimes we start with a website and sales opportunities appear a year or two later. This is typical when developing a business gradually. However, the question arises: do we need to start all over again, or can we somehow build on each other?


Absolutely yes - adding it is an option, and we even have a choice as to what will be added as our store.




You already have a live website, established Google rankings, and a loyal readership, and now you want to start selling physical products, e-books, templates, or consultations? A very common mistake I encounter in conversations with creators is the belief that launching sales requires building the entire website from scratch. In reality, an e-commerce module can be seamlessly integrated into your existing website without sacrificing your SEO.


Why is building sales better than restarting?


  • Protecting your earned traffic: Changing your domain or migrating your entire CMS always carries the risk of fluctuating Google rankings. By keeping your base site, you retain all of your domain's historical authority.

  • Save time and budget: Instead of re-commissioning a costly project, you focus solely on the product, payment and shopping cart layers.

  • Consistent customer experience: Your customers already know your site layout and trust your brand – adding a simple purchase path is a natural step for them.


Methods of implementing e-commerce on an existing website


  • Embeddable widget (e.g., Ecwid, Shopify Buy Button): Generate a short snippet of code in your vendor's dashboard and paste it anywhere on your website (works with plain HTML, builders, or older CMSs). The store loads as an interactive widget with a full cart and checkout panel.


  • Dedicated checkout for digital products (EasyTools / EasyCart): A tool designed for selling digital files, webinars, consultations, templates, and e-books. Instead of building a complex store with a multi-level shopping cart, you generate a quick checkout tile or pop-up checkout integrated with BLIK and Stripe. The system automatically sends the file to the customer after the order is paid and can immediately issue an invoice (e.g., via Fakturownia, iFirma, or wFirma).


  • Dedicated app or plugin (Wix Studio, WooCommerce): In systems like Wix Studio or WordPress, simply activate the internal store module. In WordPress, you install the e-commerce plugin, and in the builders, you enable the official commerce app tied to the website's database.


  • Shop on a subdomain ( sklep.twojadomena.pl ): A good solution when the main website is based on a very specific or closed technology, and you need a fully-fledged, separate engine.



Comparison of costs, commissions and margins across suppliers

When choosing a tool, it is worth paying attention not only to the fixed subscription fee, but above all to the total transaction cost (platform commission + payment operator commission such as BLIK, PayU or Stripe).

Supplier / Solution

Fixed base subscription

Platform commission on sales

Payment gateway commission (PL / EU)

Best use

EasyTools (EasyCart)

Free plan (or subscription from approx. PLN 99/month)

Approximately 5–7% on no-subscription plans; 0–1% on higher plans

Depends on Stripe/Przelewy24 (approx. 1.2% – 1.4% + fixed fee)

Digital products, e-books, consultations, simple one-time payments and subscriptions

Ecwid

Free plan (up to 5 products) or from approx. $19/month

0% (regardless of plan)

Standard commission of the connected gateway (e.g. PayU, Stripe: approx. 1.2–1.5%)

A universal shop widget to embed on any existing website.

Shopify (Buy Button / Starter)

From $5/month (Starter)

5% (in the Starter plan at external gates)

Depends on the payment gateway (approx. 1.4–1.9%)

Selling individual physical products directly from the blog

WooCommerce

0 PLN (free license; hosting and domain costs)

0%

Payment operator commission (e.g. PayU / Przelewy24: approx. 1.2–1.7%)

Your own, fully controlled WordPress store with no commission fees

Wix Studio / Wix eCommerce

From approx. PLN 80–120/month (business plans with payment support)

0%

Commission of the connected operator (e.g. Stripe, PayU: approx. 1.2–1.5%)

Stores integrated directly with your own website design in the Wix ecosystem

What to remember before publishing an offer?


  • Payment methods tailored to the market: In the Polish market, the lack of BLIK payments drastically reduces conversion rates. Make sure your chosen payment method (whether EasyTools, Stripe, or PayU) allows for one-click payments on your phone.


  • Post-purchase automation: For digital products, immediate sending of the download link and invoice without your manual intervention is crucial.


  • Formal issues: Make sure to include checkboxes with consent to the loss of the right to withdraw from the contract upon immediate download of the digital file, sales regulations and privacy policy.


Introducing sales to an existing website doesn't require a technological revolution. If you sell knowledge or digital files, a lightweight checkout like EasyTools will get you up and running in a day; if you're planning a large physical inventory, a flexible Ecwid widget or a module built into your CMS will ensure scalability without unnecessary overhead and hefty commissions on purchases, as that money can be allocated to paid advertising and other purposes.


Sometimes we lack insight, and this leads to customers jumping from one store to another because they initially chose the wrong one and certain necessary solutions are missing. This is a key issue to address from the very beginning, but in this case, it should come from the person creating the website or store, unless we're doing it ourselves and don't have time for proper research :)


If you need anything, you know where to find me.
