Building an online store is no longer optional. With eCommerce sales projected to grow past $7 trillion globally by 2026, businesses that do not invest in a strong digital storefront risk being left behind.
However, the big question most founders and marketers have is: What is the real cost of an SaaS eCommerce website?
Every website comes with variables that rule out a one-size-fits-all approach. The cost of your eCommerce website depends on factors like platform choice, design complexity, integrations, and ongoing maintenance.
Several factors influence how much you will pay to build and maintain your eCommerce site.
Let's explore each one.
The number of products, product categories, and whether you plan to sell internationally all affect the total investment. A store with 20 products is very different from a store with 2,000 SKUs and multi-currency support.
You can launch with a template for under $300 or commission a custom theme that runs into five figures. Design decisions should balance budget with the need for unique branding.
Hosted solutions like Shopify and BigCommerce bundle hosting and support, while self-hosted platforms like WooCommerce and Magento require more technical setup. Each comes with unique pricing models.
The more advanced your feature set, the higher your development costs. Think of subscription billing, multilingual sites, loyalty programs, or integrations with CRM and ERP systems.
eCommerce website cost is shaped as much by your ambitions as by your technical choices. Start with the must-haves, then scale features as your business grows.
One of the largest variables in eCommerce website cost is the platform you choose.

Shopify is ideal for beginners because of its simplicity, while WooCommerce gives more flexibility if you already use WordPress. Magento suits enterprise-level stores, but the setup costs are significant.
eCommerce platform fees add up over time. Do not just compare monthly prices, but factor in apps, plugins, and transaction costs that grow as you scale.
The look and feel of your online store directly influence conversion rates.
When budgeting, consider these tiers of design investment:
Remember that design is not just about looks. Usability, mobile responsiveness, and accessibility all play a role in customer trust and sales.
Beyond design, development covers functionality. Your choices here will heavily influence online store development costs.
Custom backend features such as inventory management, product variants, or advanced search filters can add thousands to your budget. API integrations with CRMs, ERPs, or automation tools increase costs further but save time and headaches in the long run.
While DIY may look cheapest, the long-term ROI of professional development often outweighs the upfront savings.
Every eCommerce store needs reliable hosting and ongoing maintenance.
Options include:
You will also need SSL certificates, regular software updates, and security monitoring. Budget for monthly or annual maintenance contracts to avoid downtime.
A beautiful site without traffic will not succeed.
Your initial eCommerce website cost should include marketing and SEO setup, such as:
Investing in marketing from day one ensures you are not just building a store, but an engine for growth.
As you grow, you may need integrations beyond the basics.
And, of course, this increases your eCommerce website cost.
Common add-ons include:
Each add-on increases your overall cost, but also improves the customer experience and efficiency.
