What Do You Need to Start an Online Store?

Starting an online store takes more than a website with a shopping cart. You need a product people want, a registered company, a platform that fits your size, payment solutions customers trust, shipping that does not eat the margin, and visibility that brings visitors.

The technical part is the easiest part, and we take it. We set up the platform, payments, product catalogue and shipping, and build in technical SEO from the start. You concentrate on your products and your customers.

Mementor has built online stores since 2015, from small specialty shops to stores with reseller programmes and thousands of products. If the store needs special features, we build them through web development.

Six Steps from Idea to First Order

Product and range. Decide what to sell and to whom. A narrow range with a clear audience beats a broad store without a profile.
Company and the formalities. Register a sole proprietorship or a limited company, and remember that terms of sale, right of withdrawal and a privacy policy must be in place before you open. We set up the templates, your accountant confirms the formalities.
Platform. WooCommerce gives the most freedom and ownership, Shopify is the fastest to get going. We recommend based on your range and your plans, not on what is easiest for us.
Payments. Card, Vipps and Klarna cover what Norwegian customers expect. We connect and test it all before you open.
Shipping. Shipping options and rates are set up around what you actually send, and where. A wrong shipping setup is the most common reason new stores lose money.
Visibility. A store nobody finds sells nothing. Technical SEO is included from the start, and SEO and Google Shopping take the store further.

An Online Store Is a Shop. Not an IT Project.

Frequently Asked Questions

Wondering about something else? Ask your question here. We answer within one working day.

How long does it take to get an online store going?

It depends on the complexity. Simple stores can launch in two to four weeks, while more tailored solutions take one to three months. You get a timeline with the quote.

What do you need to start an online store?

You need a domain name, hosting, a store platform and a design that represents your brand. On top of that come a payment solution, an SSL certificate, shipping setup and a plan for visibility in search. We set all of it up.

Which platform should I choose?

It depends on what you sell and how you work. WooCommerce gives flexibility, Shopify is simple to run, and Magento handles large catalogues. We recommend based on your needs, not on habit.

Is SEO important for an online store?

Yes. Good SEO means customers find you without you paying for every click. Better rankings bring more traffic, and relevant traffic from search turns into sales more often.

Do you help after the store has launched?

Yes. We follow up on performance, updates and marketing after launch, and help you further as the range or the traffic grows.

What does it cost to start an online store?

The platform costs are low, from a few hundred kroner a month for licences and hosting. The big difference lies in the setup: a store with the right structure, payments, shipping and visibility from the start costs more than a template, but earns it back by actually selling. You get a fixed price before we start, with no hidden costs and no long lock-ins.

Do I need my own company to start an online store?

Yes, you must register a sole proprietorship or a limited company to sell goods online in Norway. If your turnover passes NOK 50,000 within twelve months, you must also register for VAT. We help you with the technical side of the store, and recommend that an accountant confirms the formalities around company and tax.

Can I run the store myself afterwards?

Yes, that is the whole point. You get training in adding products, handling orders and changing content yourself. If you would rather skip the technical maintenance, a Service Level Agreement (SLA) takes care of security, updates and backups while you run the store.
