When to Contact a Website Development Agency for an Online Store

Creating an online store can be a challenging task, but choosing the right approach depends on the specifics of your product business and the number of products.

Direct Sales Without a Website

If you have a small number of Instagram-friendly products, you can sell them manually through Instagram and TikTok and manage without a website for some time.

Developing a Showcase Website

If your product is not suitable for direct sales but the number of items is limited, consider developing a showcase website. This is a good option for testing your product segment or for selling up to 10 types of products.

Creating an Online Store on a Website Builder

If your audience is not demanding and you don't need synchronization with accounting and inventory systems, consider creating an online store on a website builder. It will be cheaper and suitable for mid-priced products with up to 300 items.

Ordering a Full-Service Online Store

If you have a large number of products, sell both wholesale and retail, each product has different characteristics, and you need synchronization with inventory and logistics systems or you accept payments from different countries, you need a custom-developed online store. Although this is a significant investment, such a website will provide any necessary functionality and competitive advantage, high speed, and the possibility of adding extra features in the future.


What Determines the Cost of Creating an E-commerce Website?

The prices for developing an online store can vary significantly. Let's take a closer look at what determines the cost of creating an e-commerce website and what to consider when choosing a contractor to develop your dream site.

E-commerce Website Design

The cost of designing an online store depends on your needs, corporate style, and additional preferences. In some cases, you can consider a template option with minor modifications. This approach allows you to reduce the design cost, as template designs use standard blocks, making development cheaper.

Turnkey E-commerce Website Development

Every retail business has its own specifics, so the functional requirements for an online store can also vary. The basic structure of an online store includes a product catalog with specifications, a shopping cart, and an online payment module. Additional features such as synchronization of products with variations in specifications, stock synchronization across different warehouses, and integrating a logistics module with cost calculation will be more expensive.

Dynamic advertising content on the site shows very good results, but implementing such functionality also increases the cost of the online store.

We conduct comprehensive testing of the online store to ensure its flawless operation. For smaller projects, we use manual testing, and for more complex ones, we perform additional load and performance tests.
