About

We build the shops, so you can keep trading.

Concept500 is a specialist e-commerce team. We design, host and maintain webshops for businesses that outgrow generic templates — and we’ve been doing it long enough to know what actually works.

Our story

From a niche marketplace to a platform for many trades

Concept500 started with a single question: could we build a proper online home for specialist dealers whom generic e-commerce platforms had never served well? Our answer was MilitariaMart — a marketplace and shop platform purpose-built for dealers of militaria, antiques and collectibles.

That platform grew. Today MilitariaMart powers over 140 specialist dealer shops across Europe, and we run it as a self-contained business under the Concept500 umbrella. Along the way, the same underlying platform matured into something we could offer beyond that niche — to rare-book sellers, vintage audio traders, artisan makers and anyone else whose catalogue doesn’t fit a drag-and-drop builder.

Concept500 is a small, deliberate team. We answer the phone. We know your shop. When something breaks, you talk to the person who can fix it.

What we believe

Boring software. Calm trade.

The best platform is the one you don’t have to think about. Our goal is to make the technical side of running an online shop genuinely uneventful — predictable, reliable and out of your way — so you can focus on the parts of your business you actually enjoy.

We don’t chase trends. We don’t rebuild the admin panel every year. We ship changes that customers have actually asked for, and we maintain the rest carefully.

We work with businesses that plan to still be trading in ten years. That shapes everything we build.

Our values

How we work with customers

Clear, honest pricing

A small setup fee and a small monthly charge. Everything inclusive. If we can’t justify a cost, we don’t add one.

Specialist, not generic

Our product exists for businesses that need more than a template. We’ll never water it down to chase a broader market.

Talk to a human

Phone and email are answered by the people who build and maintain the platform — not an outsourced help desk.

Long-term partnerships

Many of our customers have been with us for a decade or more. We build for that timescale, not the quarter.
