How to choose software for selling LEGO.

What this kind of software actually does

If you sell LEGO in more than one place, you’ve felt the friction: the same lot listed on several marketplaces, quantities that fall out of step, orders to pick from bins, prices to keep current, and a pile of incoming inventory to sort and list. Multi-channel software exists to take that off your plate. The good ones handle most or all of:

• Keeping one inventory in sync across the marketplaces you sell on, so a sale in one place updates the others.
• Preventing overselling — the nightmare of selling stock you no longer have and having to cancel on a buyer.
• Pricing and repricing across channels without editing every listing by hand.
• Intake — turning a box of bricks into listings, whether by scanning, parting out sets, or importing a file.
• Picking, packing, and shipping — pull lists, addresses, tracking.
• Insights — what’s actually selling, and whether you’re making money.
• Team tools, if you don’t run the shop alone.

Not every tool does all of this, and they differ most in two places: how they charge you, and what they cover. Those are the two things worth thinking hardest about.

The big decision: how it’s priced

This is the choice that quietly costs — or saves — you the most over a year. There are two common models.

Commission (a percentage of your sales). You pay a cut of each sale, or a percentage of your revenue — sometimes with a monthly minimum. It feels cheap when you’re small. The catch is that the bill grows with your success: the more you sell, the more you pay, forever.

Flat monthly fee. You pay one price regardless of how much you sell. Predictable, and it rewards growth instead of taxing it.

Here’s the difference, illustrated. (The commission figure is a hypothetical example — actual rates vary by tool.)

The flat line never moves. The commission line follows you up. For a growing shop, that gap becomes real money.

What else to check

Price model is the big one, but a few other things separate tools. Run down this list against whatever you’re considering — including us:

• Does it cover your marketplaces? Check that the tool syncs the specific places you actually sell, not just the popular ones. (BrickPulse covers BrickLink, BrickOwl, and eBay.)
• Does it genuinely prevent overselling, or just loosely sync? The strongest approach is a single master inventory that every channel is kept in agreement with, rather than channels trying to reconcile with each other.
• How does intake work? Scanning parts with a camera, parting out sets, and importing existing files all save enormous time. See which the tool supports.
• Do you need it to buy or print shipping labels? Some tools do this; some (including BrickPulse) intentionally don’t, because the marketplaces don’t all offer a usable way to. If in-app label purchase is essential to you, confirm it’s there.
• How does buyer messaging work? Some marketplaces don’t offer a messaging API at all, so tools handle this differently. Know what you’re getting.
• Cloud or your own machine? Some older tools need a computer left running. A cloud tool runs on its own.
• Are there real docs and support when something breaks? This varies more than you’d expect.
• Team features, if you have help: separate logins, roles, and a way to divide the work.

Where BrickPulse fits — honestly

BrickPulse is a strong fit if you sell across BrickLink, BrickOwl, and eBay, want flat and predictable pricing, value a modern interface, and want fast intake with one master inventory that keeps you from overselling.

It may not be the right fit if you need a marketplace we don’t yet support, or if buying shipping labels inside the tool is a must-have for you. We’d rather tell you that up front than have you find out later.
