A good online store has to make buying simple for the customer and management clear for the team. Products, prices, payments, invoices, orders and customer accounts should work together, not as separate tools.

We build the store around the logic your sales process needs: individual and business customers, customer-specific pricing, multiple languages, tax and shipping rules or integrations with accounting, warehouse and ERP systems.

The store is not locked into a closed platform or plugin stack. The code, data and content belong to your company, and the system can be developed further.

01 Who this is for

When an online store makes sense

  • The company needs an online store where customers can buy and the team can manage orders.
  • The buying flow needs to cover products, payments, invoices, shipping and order management.
  • You sell to both individual and business customers and want to manage both in one system.
  • Prices, customer groups or order terms do not fit a standard online-store setup.
  • Products, prices, stock, accounting or logistics need to connect directly with the store.
  • The store needs to handle campaign and seasonal traffic spikes.

02 Process

How the project works

  1. 01

    Analysis and plan

    We start with what the store needs to do: what you sell, who you sell to, how orders move and which payment methods, invoices, shipping rules and integrations are needed. By the end of the stage, you have the scope, integration list and written quote.

  2. 02

    Design and build

    Design, storefront and back-office logic are built in parallel. We set up the catalogue, cart, checkout, payments, tax and shipping rules, and when needed, data migration.

  3. 03

    Testing and launch

    We test the buying flow with real order scenarios: payments, invoices, notifications, shipping and management. We launch when the order flow works correctly from start to finish.

  4. 04

    Post-launch support

    We stay with the project to handle early edge cases, fix smaller issues and refine integrations based on real use.

03 Work example

Similar project

Rufstern — service ecommerce and order management

Rufstern needed an online store for selling services, not just a website that presents them. Customers needed to compare platforms and packages, choose the right service, pay and track their order status.

We built the public store with Next.js and the backend with Node.js. Admin tooling and APIs connect purchase, payment and fulfilment into one trackable process, while orders, payments and invoices move through one management system.

  • A store with products, categories and checkout.
  • Admin tooling and APIs support purchase, payment and fulfilment automation.
  • The admin team tracks orders, payments and fulfilment from one place.
  • Fewer manual steps between email, spreadsheets and invoicing.

05 FAQ

Common questions before we start

Do you build online stores from scratch or replace existing ones?
Both. We can build a new online store from scratch or reuse the parts of an existing store that are still useful. Before work starts, we agree what stays, what needs updating and what should be rebuilt.
Can one store serve both individual and business customers?
Yes. One store can show different prices, terms, catalogues and checkout flows depending on whether the customer is an individual or a business.
Can the store connect to accounting, warehouse or ERP systems?
Yes. We can connect the store to accounting, warehouse, ERP, PIM or logistics systems. During scoping, we define which system is the main source for products, prices, stock and orders.
How do payments and invoices work?
Card details do not pass through the store server. We use payment providers such as Stripe, Maksekeskus or another suitable solution. Invoices can be generated automatically and, when needed, connected to the accounting system.
Can our team add products and edit content without a developer?
Yes. Products, prices, categories, content pages and translations can be updated without waiting for a developer. A developer is needed for new features, not every new product or text edit.
Can the store handle campaign traffic?
Yes. We build the store to handle campaign and seasonal traffic spikes. When needed, we add monitoring, backups and a maintenance package.
Can the store support multiple languages and currencies?
Yes. The store can be multilingual from the start and support multiple currencies, VAT rates and regional shipping rules when needed.
When is this not the right service?
If you need a very simple store for selling a few products, Shopify or another ready-made platform is often a better starting point. We build custom online stores when the buying flow, management or integrations need more control.
