The sale is a moment.
The margin is the whole story.

A sale price tells you one thing. The costs behind it tell you much more. Marginspace brings them together, so you can see what your work leaves you.

More context.
A clearer next move.

You do the finding, listing, and selling. Make space to understand what’s working along the way.

Look beyond a good sale.

Consider what an item earned alongside how long it took to sell. A clearer starting point for deciding what’s worth finding again.

Notice what’s still waiting.

Your unsold stock is part of the picture too. See the recorded cost sitting on the shelf, and how long it’s been there.

Keep costs with the pieces.

A mixed lot becomes individual finds. Parts become a bundle. Keep the original costs connected as your inventory changes.

Built around your stock.
Shaped around your next move.

A few good questions.

Who is Marginspace for?

Independent resellers who want a clearer view of true costs, sales, and unsold stock. Individual finds, auction buys, mixed lots—tell us what you sell when you join.

What happens after I join?

Your place is saved and the Profit Check worksheet is ready to download. We’ll contact you when a suitable alpha place is available. Joining the waitlist doesn’t create a product account.

When will it launch, and what will it cost?

The launch date and pricing haven’t been set. Alpha invitations will go out in stages, with supported workflows and any costs explained before you accept. The waitlist is free.

Can I bring my existing inventory?

Import and migration are part of alpha planning. Tools, formats, and field coverage are still being decided. We’ll confirm what works for your records before inviting you to move them.

Are these real business results?

The previews use illustrative data, never customer records. Marginspace is designed around your own sales and stock. This page doesn’t promise a profit uplift, a particular marketplace integration, or automatic repricing.
