Online sales have seen significant growth in recent years, and more and more businesses are deciding to offer their products and services online. However, launching an online store involves much more than simply creating a website and adding products — it also requires proper business preparation, compliance with legal regulations, and well-organized payment, delivery, and customer support systems.
Good preparation can save you a lot of time, money, and business-related issues later on. That is why it is important to understand in advance what an online store should include and which obligations must be fulfilled in order for your e-commerce business to operate professionally and securely.
Choosing a business model and registering your activity
Before developing an online store, it is necessary to define your business model. An online shop can be operated through:
- sole proprietorship
- simple limited liability company
- limited liability company
- an existing company or business
During registration, it is important to select the appropriate business activities covering online sales. If you already have a registered business, in most cases it is enough to add activities related to e-commerce.
It is also advisable to define your sales process, product types, delivery methods, payment options, and future business expansion plans in advance, as these factors will later affect the functionality of the online store.
Legal requirements an online store must meet
One of the most important aspects of launching an online store is compliance with legal regulations. Customers must clearly see who operates the store and under which terms the business operates.
An online store should include:
- basic company or business information
- contact information
- terms and conditions
- delivery information
- payment methods
- return and complaint policies
- privacy and cookie policies
In online sales, consumer protection laws are especially important because customers have certain rights that must be clearly presented on the website. For example, in most cases, customers have the right to withdraw from the purchase agreement within 14 days of receiving the product.
The Most Important Laws for E-commerce in Croatia
- E-commerce Act
- Consumer Protection Act
- General Data Protection Regulation (GDPR)
- Act on the Implementation of the General Data Protection Regulation
- Fiscalization in Cash Transactions Act
- Trade Act
- Civil Obligations Act
GDPR, cookies, and user data protection
Every online store processes certain personal user data — from names and addresses to phone numbers and email addresses. That is why every web shop must comply with GDPR regulations.
This includes:
- proper collection and processing of personal data
- a clearly defined privacy policy
- secure data storage
- a cookie banner and consent management
If you use Google Analytics, Facebook Pixel, or marketing tools, users must be able to choose which types of cookies they want to accept.
Fiscalization, invoices, and payment methods
In e-commerce, it is very important to properly organize invoicing and fiscalization. Depending on the payment method, certain transactions must be fiscalized according to the rules of the Croatian Tax Administration.
Today, online stores most commonly use multiple payment methods:
- card payments
- online banking
- cash on delivery
- PayPal and other online payment services
In addition to payment systems, it is also necessary to integrate delivery services so customers can easily track orders and choose their preferred delivery method.
Before launching an online store, it is recommended to consult an accountant in order to properly define VAT obligations, invoicing, and fiscalization.
Choosing a platform and technical implementation
High-quality technical implementation plays a major role in the success of an online store today. A slow, confusing, or poorly optimized website can quickly drive customers away.
When choosing a platform, it is important to pay attention to:
- website performance
- mobile responsiveness
- SEO optimization
- system security
- easy product management
- scalability and upgrade options
- delivery and payment integrations
Some businesses choose ready-made e-commerce solutions, while others opt for fully customized web shops that offer greater flexibility and broader development possibilities.

Marketing and customer acquisition
Building an online store does not deliver results unless there is continuous traffic and a steady flow of the target audience to the e-commerce site. After launch, it is necessary to focus on promotion and attracting visitors.
Without secured financial resources for marketing activities, an online store can hardly achieve significant success or meet the expectations of the business owner. Visibility and a continuous inflow of customers require ongoing investment in advertising and promotion.
In practice, the least expensive part of the entire e-commerce development process is usually the creation of the online store itself. A significantly larger portion of the budget should be allocated to marketing activities, where it is realistic to expect that initial marketing investments will be at least 150% higher than the initial cost of building the online store.
The most common promotional methods include:
- SEO optimization
- Google advertising
- social media marketing
- newsletter campaigns
- blog content
- remarketing ads
High-quality SEO optimization can, in the long term, generate stable organic traffic from Google, which represents one of the main sales channels for many online stores.
Launching an online store is only the beginning of the business process. Regular maintenance, SEO optimization, advertising, and market adaptation are essential for the growth and development of an online business. An e-commerce store that is technically well-built and properly organized can become a strong sales channel and significantly contribute to business development and increased sales.
Warehouse organization and management
The largest cost items in an e-commerce business are typically product procurement and warehousing expenses, both of which directly affect liquidity, cash flow stability, and the ability to achieve further business growth. For this reason, it is important to view the overall business model more broadly than just the creation of an online store, including all operational, logistical, and promotional costs that arise after launch.
Warehouse costs are not limited to physical space alone, but also include workforce organization, equipment, inventory tracking systems, as well as the time and resources required for day-to-day goods management. As the product range and order volume grow, the warehouse becomes an increasingly significant operational and financial segment of the business that requires a systematic approach and clear cost control.
When launching an online store, it is important to define how products will be stored, how warehouse locations will be labeled, and how goods will be received and dispatched. Special attention should be given to synchronizing inventory levels between the warehouse and the online store so that customers always have accurate information about product availability.
As the business grows, it is advisable to consider implementing a Warehouse Management System (WMS) or integrating the online store with an ERP system. Such solutions automate a large part of the process, reduce the risk of human error, and provide better visibility over stock levels, product movement, and procurement needs.
All products offered in the online store should be physically available in stock at the time of sale. A model in which orders are forwarded to suppliers only after purchase and then wait for delivery (without previously secured inventory) significantly increases the risk of delays, shipping errors, and customer dissatisfaction. In practice, this inventory model should be avoided, as it significantly complicates reliable e-commerce operations.
Poorly organized warehousing can lead to delays in order processing, incorrectly shipped products, inaccurate stock levels, and unnecessary costs. On the other hand, a well-structured system enables faster order fulfillment, precise tracking of product availability, and more efficient procurement planning.
