BrickLink × BrickOwl

Your inventory on every marketplace, always in sync

Studloop keeps your BrickLink and BrickOwl stock level, handles your orders, writes your invoices and shows what you keep. You stop updating anything by hand.

The Studloop dashboard showing monthly revenue, the split between BrickLink and BrickOwl, cash flow and the most popular parts.

This is what you get

No mockups: this is the actual screen. Try it yourself in the demo, no account needed. The app is in Dutch for now.

The Studloop picking screen with the bin location large on screen, a photo of the part and the quantity to pick per order.
Picking along a walking route: the bin location large on screen, the quantity per order beside it, and one tap to the next part.
The Studloop buying screen with the quick entry line on top and the entered parts below it, with location, colour, quantity and price.
Buying entry without detours: number, colour, quantity and location. The selling price comes straight from your own pricing rule.

Two-way inventory sync

Sell on BrickLink and the quantity on BrickOwl drops right away, and the other way round. The sync runs on orders, so the two platforms never send each other in circles.

Order processing & picking

One overview for all your orders, a fast picker, packing lists and shipping labels (PostNL/MyParcel).

Invoices & VAT

Gapless invoices with the right VAT treatment: margin scheme, reverse charge, OSS and export, automatically.

Price, margin & signals

Pricing rules based on the BrickLink price guide, real margin per order, and best-sellers that are running low.

Part-out calculator

Enter a set number and see what the loose parts bring in against the price of the set, with the return.

Your own keys

Connect your own BrickLink and BrickOwl account. Your API keys are encrypted and used only for your store.

Who we are

We sell LEGO parts ourselves

We run a LEGO parts store ourselves; since 2024 more than 34,000 orders went through it. Keeping stock level by hand, selling the same part twice, having no idea afterwards what was left at the bottom: we have been through all of it. Studloop is what we built against it.

What sellers usually ask us

Does my BrickLink store stay mine?

Yes. You connect your own BrickLink and BrickOwl account with your own keys. Your store stays yours, with your own customers and your own terms. We sell nothing on your behalf and never sit between you and the buyer.

What happens to my API keys?

We store them encrypted and use them only for your store. You create them yourself at BrickLink and BrickOwl, and you can revoke them there at any time. Our access stops immediately when you do.

What if the sync gets something wrong?

As long as you have not turned on live sync, Studloop changes nothing in your stores: everything is a simulation you can check at your own pace. Once you turn it on, every sale sends exactly one change to the other platform. We never overwrite your whole inventory in one go.

Do I have to switch over all at once?

No. You import your inventory first and compare at your leisure whether everything lines up across both platforms. Only when you are happy do you turn on the sync.

What do you charge the 2.5% on?

On the revenue from your orders, across all your sales channels: BrickLink, BrickOwl and your own storefront. Shipping costs you pass on to the customer are left out, because that money goes straight to the carrier. On top of that it is at least €15 per month and at most €300 per month, so a quiet month stays cheap and a peak month never runs away with you.

Can I stop whenever I want?

Yes, you cancel monthly. The trial runs for 14 days and needs no credit card, so you can try it without committing to anything.
