Cartalo features and functionalities

Sales promotion tools

Thanks to the integrated marketing tools, it’s never been easier to establish effective communication with users. Amount discount, percentage discount or maybe free shipping? You set the rules for the promotion yourself. The wizard allows you to tag each group of codes so you can track the impact of your marketing efforts step by step.


Cartalo is a system that lets your store grow steadily. If you find that one country isn’t enough for your business, you can easily expand to other areas. Among the solutions offered by the platform are country-specific, multilingual and multicurrency customizations, as well as the configuration of pricing policies and tax calculations for specific markets.


Cartalo is prepared to help e-commerce managers manage content in an online store so that it’s accessible not only to search engines, but more importantly to users. Extended descriptions, meta tags, canonical tags and breadcrumbs are just some of them. You can also take care of alternative descriptions under photos and friendly looking links.

UX & mobile first

With a modern approach to website architecture design, your store will be created with target audience segments and their needs in mind. By adjusting content and features wisely, the website optimizes sales on mobile devices.

Modern design

Your store is eye-catching and fully responsive, and customers can enjoy a great shopping experience. A modern layout promotes brand loyalty, which leads to more loyal users who return to your products regularly.

Transparent rules with no additional fees

With Cartalo, there are no hidden fees. During the pre-implementation analysis, you’ll get a reliable cost estimate and the expected implementation time. You’ll also learn which processes and integrations are key to increasing the efficiency of your online sales. Remember that with Cartalo you won’t have to pay royalties and sales commissions in the future.

At this stage we will meet with you and listen to what you expect from your new e-shop. Then our team will analyze your needs and consider which solutions will be most beneficial for your business and determine the requirements for implementation.


Based on the analysis, we prepare a valuation. We are transparent, so we will present you all the components of our offer, so that you know exactly what the final price is.


We will create a document detailing the scope of implementation, describing and taking into account all the needs we heard during the initial analysis phase. The specification includes a description related to the appearance of the website, the operation of individual mechanisms and integration.


We like to have everything planned, probably you too, that is why we will divide individual works into stages, so that you know exactly what we do and what we will need from you at a given moment.


We already know how the service will look and work, we agree on the price, so it’s time to complete the formalities. This is the stage of negotiating the terms of the agreement and establishing the terms of cooperation. Once we sign the deal, we can move forward.


This is the most anticipated part of the project - the implementation of the service. We implement the specifications, and we also take care of your training with the new system. Everything to make it easy and enjoyable to use. Ready!
