Developing a potent tech stack is essential to adapting your eCommerce to evolving customer needs and to increaseing profitability. However, while vital, investing in technology requires some prior research.

With this article, we will show you how to build the best eCommerce tech stack possible.

What is a technology stack or tech stack

A technology stack is the combination of software or computer solutions that an online store integrates to enhance its operational capabilities.

The purpose of this technological ecosystem is to streamline processes and assist work teams in becoming more efficient. It encompasses all areas and departments, from web development to eCommerce logistics management.

Parts of a tech stack

A tech stack consists of two parts:

  • Front end: comprised of the components involved in the visual representation of the device or web browser, the part that faces the client
  • Back end: on the server side, referring to everything that is behind what is visible, the backbone of the online store

How to build the best eCommerce tech stack

If you want to build the best ecommerce tech stack, you should do the following:

1. Define your goals and objectives

Before selecting the tools, it is crucial that you have defined your medium and long-term goals. Keep in mind that acquiring software is expensive and time-consuming, so you should plan for the future.

2. Determine the order of integration

A phased implementation of tools is often the most efficient option. In addition to the financial investment, integrating many software programs simultaneously can lead to internal issues. You should prioritize the technology that is most crucial for your operations.

3. Considering the customer experience

Your technological ecosystem has a direct impact on your customer's shopping experience. If you want to achieve success, don't just think about reducing costs or increasing productivity; you must integrate software that enhances customer service and promotes customer loyalty.

4. Ensure compatibility

It's crucial that the applications in your technology stack are compatible with each other and enable an effective flow of information. When researching software, inquire about integration times and API information. If the integration time is lengthy, also consider the opportunity cost.

5. Evaluate the real ROI of building your own tech stack

First, you must calculate the total implementation and maintenance costs over time. Then, determine how this stack will improve operational efficiency, productivity, and ultimately, the company's revenue.

Not always is the cheapest option the most profitable. Paying less for incomplete solutions that don't truly address your issues or lack scalability options can be very detrimental to your return on investment.

Example of an efficient and inefficient technological stack

When building your own ecommerce tech stack you can opt for:

A) High-maintenance tech stack

Let's look at an example of an online store that uses many disparate tools. This is the least efficient option, as maintaining many software simultaneously is more costly and can lead to compatibility issues.

  1. eCommerce platform (Shopify)
  2. Customer management (Hubspot)
  3. Digital marketing (Mailchimp)
  4. Customer support (Gorgias)
  5. Shipment tracking (Sendcloud)
  6. Logistics (Packlink)
  7. Returns (ReturnGo)

B) Low-maintenance stack

This option is much more efficient. It integrates comprehensive solutions to manage a significant portion of operations. In this case, we will look at a tech stack of a store that uses Outvio for its post-sales.

  1. eCommerce Platform (Shopify)
  2. Customer Management (Hubspot)
  3. Digital Marketing (Mailchimp)
  4. Customer support, Logistics, Shipment tracking, Returns, Exchanges (Outvio)

As you can see, the second option requires much fewer software tools to maximize its results. By choosing Outvio to optimize all your post-purchase operations, you are able to avoid integrating other solutions and minimise risk and cost associated with it.


Building the best eCommerce tech stack is a crucial investment for long-term success. By understanding your needs and selecting the right technologies, you can maintain a much more efficient operational level focused on the customer experience.

Remember to thoroughly review each tool to create the best technological stack and to start making your eCommerce profitable as soon as possible.
