Already integrated with Onderdelenlijn · 1,000+ suppliers on the platform

The opportunity

Onderdelenlijn is your distribution channel. Is it working as hard as it should?

Onderdelenlijn connects over 1,000 automotive parts suppliers to garages, dismantlers, and buyers across the Netherlands. When someone searches for a part, your inventory shows up — or it doesn't.

The difference between showing up and missing the sale is usually a systems problem, not a parts problem.

See how we fix this →

Your inventory isn't always live

If your stock data isn't syncing in real time, buyers see outdated availability — and go elsewhere.

Manual processes eat your margin

Manually updating listings, responding to requests, and processing orders takes hours your team doesn't have.

Your own website is a dead end

Most parts suppliers send traffic to a basic site with no inventory search, no live pricing, and no self-service for buyers.

The solution

One integration. Your entire parts operation, connected.

We build a custom integration layer between your inventory system, your website, and Onderdelenlijn — so everything stays in sync automatically, with no manual work in between.

The process

From first call to live integration — in 4 steps.

No long contracts. No technical jargon. We handle the complexity so you can focus on your parts business.

Discovery call

We learn how your business works — your inventory system, how you use Onderdelenlijn today, and where the friction is.

⏱ 30 minutes

Integration design

We map out exactly what needs to connect and how. You receive a clear technical proposal with scope, timeline, and fixed price.

⏱ 3–5 business days

Build & connect

We build the integration, connect your inventory to Onderdelenlijn and your website, and test everything end to end.

⏱ 3–8 weeks depending on scope

Go live & support

We launch, monitor, and stay available for support. As your inventory or needs grow, we scale the integration with you.

⏱ Ongoing

Are you interested?

This is built for parts suppliers who are ready to scale.

We work best with businesses that are already active on Onderdelenlijn (or planning to be) and want to stop managing their sales channel manually.

Talk to us about your setup →

Right fit:

✔ You're a dismantler, wholesaler, or parts specialist selling on Onderdelenlijn
✔ You manage a large parts inventory (hundreds to tens of thousands of SKUs)
✔ You want live inventory on your own website — not just on the marketplace
✔ Your team spends too much time on manual data entry and order processing
✔ You want to grow your online sales without growing your admin overhead

Not the right fit:

✗ Businesses with fewer than 50 active SKUs (a basic listing is enough)
✗ Businesses not yet on Onderdelenlijn or similar platforms
✗ Businesses looking for a quick-fix website with no system depth

Why Virtual Bears

We've already built this. We know what breaks.

Integrating a live parts inventory with a B2B marketplace isn't a standard web project. The data structures are complex, stock changes constantly, and errors cost you sales. We've navigated this before — so your integration is built right from day one.

Talk to us about your setup →

Experience — We know the platform

Hands-on experience with Onderdelenlijn's data structure, API behaviour, and how suppliers succeed on it.

Approach — Custom, not templated

Your inventory system is unique. We build around your existing setup — no forced migration to a new platform.

Scope — Fixed price, fixed scope

You get a clear proposal before work starts. No hourly billing surprises. No scope creep.

Continuity — We stay involved

After go-live, we monitor, maintain, and improve your integration as your business evolves.

Frequently Asked Questions

Questions we get from parts suppliers.

Do we need to be on Onderdelenlijn already? expand_more

Ideally yes — this integration works best for suppliers already active on the platform. If you're not yet listed, we can help you get set up first. Either way, the first call is the right starting point.

What inventory system do you work with? expand_more

We work with most setups — whether you're running a custom database, an ERP system, spreadsheets, or a parts-specific management tool. Part of our discovery process is understanding your current system and building around it, not replacing it.

How long does the integration take to build? expand_more

Most integrations are live within 3–8 weeks. The timeline depends on the complexity of your inventory structure and how many systems need to connect. We define this precisely in the proposal — before any work starts.

What does it cost? expand_more

We price per project, not per hour. After the discovery call, you receive a fixed proposal with a clear scope and price. No hidden fees, no ongoing surprises. We can discuss a rough range during the first call once we understand your setup.

Will this work with our existing website? expand_more

In most cases, yes. We can add a live parts search and inventory layer to your existing site. If your current website isn't suitable, we can build a new one as part of the same project — we'll advise you honestly after seeing your setup.

What happens after the integration goes live? expand_more

We offer ongoing support and maintenance packages. We also monitor the integration proactively — if something breaks or the platform changes, we fix it. Most clients stay with us on a retainer after the initial build.
