How many slabs does this job actually take?
You already draw your units. StoneNest takes the DXF you export from your ERP or CAD, nests it onto slabs, and returns a conservative, validated slab count for the bid — in seconds, on your own PC — works offline.

The results panel on a multifamily demo job (Ridgeline Flats — 3 unit types, 108 units): slab count, yield, and the nested layout.
One slab is most of the license.
A 3cm quartz slab typically runs in the $600–$1,800 range installed. On a multifamily bid measured in dozens of slabs, an afternoon of manual layout compresses to minutes — and the count that comes out has already been checked by an independent validator before it's allowed to export. StoneNest costs less than the first slab on the job.
How it works
You already draw the units in your ERP or CAD. StoneNest turns that same drawing into an accurate slab count — no re-drawing, no manual takeoff.
- Drop in the DXF you export from your ERP or CAD — one per unit type — and set quantities (up to 18 types on a licensed seat)

Validated before it becomes a bid.
Validator gate
StoneNest refuses to export a layout that fails validation — overlaps, off-slab placement, and kerf violations are caught before you ever see a DXF.
Deterministic
Same input, same settings, same count — every run, on every machine. Nothing about the result depends on a server, an account, or the day you ran it.
Conservative by design
When a piece doesn't cleanly fit, StoneNest opens a new slab rather than force-fitting it. That's a deliberate, documented trade-off, not a bug.

A month of StoneNest costs a fraction of one slab.
A 3cm quartz slab typically runs $600–$1,800 installed. StoneNest's early-adopter seat is $69/mo for the first 25 shops — rate locked for life while you stay subscribed — then $99/mo once early-adopter seats fill; comparable countertop software runs $100–$800 a month.
