Custom e-commerce development for an Estonian company when the existing platforms are too narrow and you need a solution that takes into account your business needs, processes and goals. Over 20 years of experience with WooCommerce and custom development.
E-commerce development differs from traditional e-commerce in terms of depth. It’s not just about setting up a ready-made template, but a solution built around your business processes, integrations and user experience. Web Systems has created dozens of custom e-stores for Estonian companies where a standard WooCommerce solution alone was not enough. In this guide, we’ll talk about when custom development is needed, what technologies we use and how the process works.

What is e-commerce development and who is it for?
E-shop development means creating a technical solution for your online shop, either by adapting an existing platform, such as WooCommerce, to your needs or by building a completely custom solution. It’s more than just installing a ready-made template: it’s combining business, technology and user experience into a fully-functional e-store.
E-shop development is particularly suited to companies for whom a simple off-the-shelf solution is no longer enough. For example, when integrations with business software (Directo, Merit Aktiva, Erply), complex pricing rules for B2B customers, multi-language and multi-currency operation or a specialised user experience that cannot be created with standard templates are required. For a broader overview, see also the e-commerce service, which includes both standard and customised solutions.
How is development different from typical e-commerce?
A typical e-store is built on top of WooCommerce or a similar platform, often using a ready-made template. Ecommerce development goes deeper than that. Here are the main differences:
Custom code
Development means writing code for your specific need: new features that do not exist in a ready-made template. This means business logic does not have to be bent around platform limitations.
Deep integrations
The e-shop can exchange data with CRM, ERP, warehouse system, logistics and payment solutions — in real time if needed, bidirectionally and according to specific business rules.
Custom user experience
The solution is not limited to a ready-made template — the user journey is designed around your customers. For example, B2B configurators, price calculators and custom filter systems.
When custom e-commerce development needed?
Not all businesses need custom development. A smaller e-store with a simple product catalogue and a normal shopping flow can often do very well with off-the-shelf WooCommerce solutions. Custom development becomes necessary when at least one of the following situations occurs:
- B2B complex pricing rules: special prices for contract customers, volume discounts, prices based on customer groups or VAT tax breaks for foreign companies.
- Products through the configurator: not only ready-made SKUs, but the possibility to build a product based on options, sizes, materials and accessories. The price is calculated dynamically.
- Multiple warehouses or multiple markets: products are held in multiple warehouses and shipments move according to stock levels or to the nearest delivery point. In addition, multiple currencies and tax regimes may come into play.
- Deep ERP integrations: an e-shop needs real-time synchronisation with the ERP. Orders go into ERP, stock comes into the e-shop and price changes are automatically synchronised.
- High-volume product catalogues: 10,000+ products, many variants and a sophisticated filtering system. In such cases, performance and data structure need special attention.
- Customised order flow: multi-step purchasing process, project-based orders, RFQs or bid management.
- Subscriptions and recurring orders: recurring orders, order recovery, recurring billing or automatic generation of invoices at fixed intervals.
If your needs fit within a ready-made platform, we are also WooCommerce e-commerce store development specialists. We will choose the right approach after mapping your needs.
WooCommerce development vs a fully customised solution
In practice, for e-commerce development projects, we usually choose one of two approaches: a WooCommerce customisation or a fully customised solution. Both have their own strengths and a suitable use case:
WooCommerce customisation
WooCommerce is used as the foundation, on top of which we build the specifics your business needs: a custom theme, plugins and integrations. Suitable for many Estonian companies up to medium volume. Development is usually faster, SEO capability is good and many solutions can be built on the existing platform.
Fully customised
We create the solution from scratch, for example on Laravel, Node.js or a custom database. Suitable for high-volume projects with complex rules or special performance requirements. See also the software development service.
The majority of Estonian SMEs’ e-shops fit into the WooCommerce framework. A fully customised solution is a larger investment and is particularly suited to larger companies or projects with very specific needs. During the first free consultation, we will help you choose the right approach. If you are interested in the price structure, please see the e-commerce price list.
Integrations with Estonian systems
Integrations are often at the heart of e-shop development. This is where customised development delivers the most value. For more than 20 years, we have been interfacing e-stores with many of the systems used in Estonia:
Business software
Directo, Merit Aktiva, NOOM, Erply, SAF, Eeva, Excellent. Orders move in real time where needed, stock levels are synchronised and invoices are generated automatically.
Logistics and parcels
Itella SmartPost, Omniva, DPD, Venipak, Bring. Parcel label creation, shipment tracking and courier requests can be brought directly into the e-shop workflow.
Payment solutions
Montonio, Payment Centre, Stripe, EveryPay, MakeCommerce. The purchasing process must be secure, fast and compliant. We can also add recurring payment support where needed.
CRM systems
HubSpot, Pipedrive, Salesforce, Bitrix24. Customer data flows between the e-shop and the sales system, helping to manage leads more effectively.
Email marketing systems
Mailchimp, ActiveCampaign, Klaviyo, HubSpot Marketing. Automated email campaigns based on purchasing behaviour and personalised content according to customer actions.
Specialised systems
Many industries use specialised systems, such as BIM in construction or MES in manufacturing. We integrate these too, often as custom development. Read also about workflow automation.
The e-shop development process step-by-step
A successful e-commerce development project needs a clear process. During the initial consultation, we will map your needs and prepare a specific offer based on these.
1. Needs mapping
A free consultation where we discuss your business goals, target audiences and technical requirements. We map integrations, special rules and workflows.
2. Technical design
We select the right platform — such as a WooCommerce customisation or a fully custom solution. We establish the architecture and integrations, and send a quote with a timeline.
3. Design and UX
We create the user journey and design prototypes in Figma. We review the purchasing process logic, mobile and desktop experience, and the key conversion points.
4. Development in iterations
We build the e-shop in 1–2-week stages. Each stage shows the client real progress and feedback feeds into the next development round.
5. Integrations and testing
We connect ERP, CRM, logistics and payments. We test standard purchasing flows and edge cases. We use a staging environment before publishing.
6. Launch and maintenance
We launch the e-shop in the live environment. After publication, we can continue with the maintenance service: updates, backups and further development.
What is the difference between us and other providers?
20+ years of experience
We have been developing e-shops for Estonian companies for over two decades. This experience helps avoid typical mistakes and choose solutions that work even after launch.
Development + maintenance hand in hand
The same team that builds the e-shop can also keep it running. This means one contact, clearer accountability and a better overview of the entire solution’s technical background.
Knowledge of Estonian systems
Directo, Merit, Erply and other systems used in Estonia are familiar to us. In many cases, we can start integration faster because we have prior experience and reusable solutions in place.
Web Systems’ e-shop development goes hand in hand with SEO service and maintenance if required. This way you get a solution that covers build, visibility and day-to-day operations.
Frequently asked questions
What is the difference between developing an e-shop and making an e-shop?
E-commerce is a broad concept, covering both a simple e-shop with a ready-made template and a more complex solution. More specifically, e-commerce development refers to technical development, such as a WooCommerce adaptation or a fully customised solution. Development projects are usually larger and involve deeper integrations. Read also about the e-commerce development service.
How long does it take to develop an online shop?
It depends on the size of the project. A customised WooCommerce e-shop with simpler integrations can be completed in around 6-10 weeks. Larger projects with complex ERP integrations and special rules can take 3-5 months. For a fully customised solution, you can expect around 5-9 months. We can give you a more precise timeline during the first free consultation.
Can we connect the e-shop to our own business software (Directo, Merit, etc.)?
Yes, we have interfaced e-shops with many of the business software used in Estonia, including Directo, Merit Aktiva, NOOM, Erply and SAF. We have previous experience and reusable solutions for several systems. If your system is not on the list, we will assess the API capabilities and build a separate interface if necessary.
Is WooCommerce sufficient for custom development?
Mostly yes. WooCommerce is a flexible platform on top of which you can build many different solutions. A fully customised solution is worth considering especially for very large volumes, strict performance requirements or very specific business rules. See also WooCommerce e-commerce solutions.
What happens after the e-shop is ready?
After publication, we can continue to provide maintenance services: updates, security, backups and further development. See also our website maintenance service, which is also suitable for e-shops. For larger projects, we will agree on a contact person and, if necessary, SLA terms.
Is your e-shop SEO-friendly?
Yes, we build e-stores with SEO in mind: well thought-out structure, schema data, fast loading and mobile-friendliness. If you would like active SEO work, such as keyword analysis, content creation or link building, we can combine maintenance with an SEO service.
How to get started with an e-commerce development project?
The easiest way is to fill in a contact form and ask for a free consultation. At the first meeting, we will map out your business needs, expectations for integrations and give you an initial plan: what approach to use, what timeframe to consider and what size the project could be.
