StoneApp by StoneGrid is a respected, "for fabricators, by fabricators" all-in-one ERP — CRM, quoting, scheduling, purchasing, inventory, and accounting in one cloud. SlabOS overlaps on operations, then leads with the layer StoneApp's own marketing doesn't: live 2D drawing into real-time 3D, automatic slab nesting, and a homeowner portal.

StoneApp runs the business end-to-end. The question is whether your shop also wants the drawing, 3D, and yield engine in the same login — see what that looks like.
StoneApp by StoneGrid is an all-in-one business-management system for stone shops — CRM, quoting, scheduling, purchasing, inventory, and accounting in one cloud, mobile-ready tool. It was built by a team that comes from the stone industry and is sold and implemented through the Stone Services Group network. We'll be fair about it: the operations depth is real.

StoneApp has a quoting module with an "SA Drawing tool" and excess/waste material calculations. SlabOS quotes too.
Both schedule crews. StoneApp leads with auto-scheduling and route view; SlabOS includes a mobile crew app.
Both track slabs. StoneApp's inventory depth (barcode, multi-warehouse) is a genuine strength.
Both sync to QuickBooks. StoneApp also lists Sage. Accounting is part of both stories.
This isn't a tool that can't do what StoneApp does. Both quote, schedule, track inventory, and sync QuickBooks. If your only goal is CRM-to-cash operations, StoneApp is a strong, fabricator-built choice — and we won't pretend otherwise.
The decision comes down to one thing: do you also want the visual quoting and yield engine living in the same login? That's where the two diverge — next chapter.
StoneApp's own marketing centers on running the business — CRM, scheduling, purchasing, inventory, accounting. Its site lists a quoting drawing tool and waste calculations, but it does not lead with live 2D-to-3D, automatic slab nesting, a homeowner 3D portal, or a built-in AI assistant. That's the SlabOS wedge — the design-and-yield engine, in the same platform that runs the shop.

SlabOS runs automatic best-fit slab nesting on every job — roughly 30,000 placement operations testing layouts no estimator has the hours to chase by hand. StoneApp's own site advertises excess/waste calculations; it doesn't describe automatic nesting, so we won't claim it does or doesn't. The honest framing: automatic yield optimization is the SlabOS differentiator.
Canadian Countertops (David Scott, Vancouver) used SlabOS slab-nesting yield to underbid competitors on a $1M+ job — and kept their margin while doing it. That's the attributable result behind the automatic-nesting story.
SlabOS clearly understands how to strike the right balance between fabrication and software. My only gripe: I didn't discover it sooner.
UI, integrations, performance, pricing ROI, sales features, support, onboarding, AI, the quoting engine, KPIs. Nothing to dislike — it's everything we've ever wanted.
SlabOS's reading of publicly available information as of 2026 (StoneGrid's official site and reputable press) — not a statement of fact about StoneApp's current product, which may differ or have changed. A dash (—) marks where SlabOS places its emphasis, not a definitive claim about StoneApp's roadmap. Items marked "not stated on its site" mean we could not verify them from StoneApp's own materials this run — they are not assertions that the feature is absent. No public StoneApp pricing was found; third-party figures conflict and are unverified. Verify directly at stonegridusa.com.

The reason shops stay put is data. So we move it — accounts, quotes, jobs, and the actual drawings. One shop migrated 20,000+ jobs and 18,000+ quotes in about 4 hours, with nothing lost. They were quoting in SlabOS the same day.
“All of it came over in an afternoon — 18,000+ quotes and our full job history migrated in about 4 hours. Nothing was lost. We were quoting in SlabOS the same day.”

Book a demo — we'll draw one of your real jobs in 3D, nest it onto a slab automatically, quote it with real per-slab pricing, and show you exactly how your data comes across.

StoneApp by StoneGrid is an all-in-one business-management / ERP system for stone fabricators — CRM, quoting, scheduling, purchasing, inventory, and accounting in one cloud, mobile-ready tool. It was built by a team that comes from the stone industry and is sold and implemented through the Stone Services Group network. Its own marketing centers on running the business; its quoting module includes an "SA Drawing tool" and excess/waste material calculations.
Both quote, schedule, track slab inventory, and sync QuickBooks, so there's real overlap. SlabOS leads with the visual quoting and yield layer that StoneApp's own site doesn't emphasize: live 2D drawing that becomes real-time 3D, automatic best-fit slab nesting (~30,000 placement operations per job), a branded homeowner portal with 3D and e-sign, and a built-in AI assistant on your own data — plus a done-for-you migration.
StoneApp's own site lists excess/waste material calculations as part of quoting, but it does not describe automatic slab nesting, so we can't confirm whether it has it — check with the vendor. What's verified is the SlabOS side: automatic best-fit nesting runs on every job, testing roughly 30,000 placement layouts to maximize yield.
StoneApp does not publish pricing on its site, and the third-party estimates we found conflict with each other and are unverified — treat StoneApp pricing as "check with the vendor." For SlabOS, book a demo and we'll set the right plan for your shop.
Yes — SlabOS does done-for-you migration including accounts, quotes, jobs, and the actual drawings. One shop moved 20,000+ jobs and 18,000+ quotes in about 4 hours with nothing lost, and was quoting the same day.
