Custom ecommerce development

A custom online store is an ecommerce system whose order flow, pricing and integrations are built around a specific business model. It differs from an off-the-shelf platform in that the trading rules are written in code rather than worked around with plugins.

Where an off-the-shelf platform runs out

A standard store works well for a simple model: product, basket, payment, delivery. The limits show once the business has rules of its own:

The price depends on the customer's contract, not on a general price list.
The product is configured from parts that constrain each other.
An order has to go through approval before it is confirmed.
Stock comes from production or from several warehouses at once.
The buyer is a company that needs deferred payment and an invoice.

Integrations that do the work

Accounting: invoices and payments flow automatically, with no manual entry.
Warehouse and ERP: real-time stock levels and reservations, so you never sell what you do not have.
Couriers: shipments, labels and tracking numbers from one place.
Payments: banks, cards, deferred payments for B2B customers.

Choosing the platform

Custom, PrestaShop and WooCommerce are all tools. We choose based on need: for a standard product range with a typical flow, an off-the-shelf platform will be cheaper; for unusual logic, a custom solution will cost less in the long run than ten plugins that conflict with each other and break with every update.

Migrating from an old store

We migrate products, customers and order history, and preserve SEO with a 301 redirect map. Every old URL gets an equivalent, so the rankings and links you have built up keep working.

If the store needs to connect to the rest of your company's systems, see integrations and automation. To bring in traffic, see digital advertising.

FAQ

Frequently asked questions

When should you choose custom ecommerce development over an off-the-shelf platform?

When your trading logic is unusual: customer-specific pricing, complex product configurations, B2B order approvals, or stock synchronised with production. If the product range is standard and the process is simple, an off-the-shelf platform will be cheaper and faster.

Can an existing online store be migrated without losing data and SEO?

Yes. We migrate products, categories, customers and order history. SEO is preserved with a 301 redirect map: every old URL points to its equivalent in the new structure, so your rankings are not lost.

Which systems can the online store integrate with?

Accounting software (for example Lithuanian systems such as B1, Rivilė and Directo), payment providers, courier services with shipment creation and tracking, warehouse or ERP systems, and email marketing tools.

What does B2B ecommerce functionality include?

Price lists for registered customers, discount groups, an order approval workflow, deferred payments, ordering by product code and quick reordering from order history.

How does a custom solution differ from PrestaShop or WooCommerce?

The platform is a tool, not the essence of what we offer. If a standard platform covers your needs, that is what we use, set up properly without ten conflicting plugins. We build custom when the platform's model contradicts your business logic.
