Carbon vs. Fulcrum

Fulcrum and Carbon both replace legacy manufacturing software with something modern — but Fulcrum runs the shop floor and syncs the books to a separate system like QuickBooks. Carbon unifies ERP, MRP, MES and QMS — with native accounting and job costing — on one open, API-first data model, with pricing you can read on the website.

Being fair

Where Fulcrum still fits

Fulcrum is a solid modern manufacturing ERP, and if a fully managed, closed SaaS is exactly what you want, it does the job. Carbon is for teams that also want the source code, the full API surface, and the option to run it themselves.

Signs to switch

Why teams pick Carbon over Fulcrum

Your books live in another system

Fulcrum runs the floor but keeps the ledger in QuickBooks, so cost, inventory and accounting never fully reconcile. In Carbon, accounting and job costing are native — they roll up from the same records as production.

You don't want to be locked in

Fulcrum is proprietary and cloud-only. Carbon is source-available — self-host it, extend it, and keep your data in a Postgres model you own.

You want pricing you can read

Fulcrum is quote-based and sold on revenue, with no public trial. Carbon publishes per-user pricing and a 30-day free trial — evaluate it before you talk to anyone.

The case for Carbon

Why manufacturers choose Carbon

One system, one record

ERP, MRP, MES and QMS share a single data model. Quote, plan, buy, build, inspect and ship all write to the same record — nothing to integrate, nothing to reconcile.

Open, and yours

The source is yours and the data lives in an open Postgres model you can host, extend and query directly — no black-box cloud, no lock-in. A REST API and a hosted MCP server expose the whole backend, not a curated slice, and it's CMMC / NIST 800-171 ready for defense work.

Configuration and CAD, built in

A parametric configurator resolves BoM, routing and price per order, and a native 3D/STEP viewer puts the part where the work is — capabilities Fulcrum doesn't offer.

Transparent pricing

Published, per-user pricing and a 30-day free trial. No revenue-based quote, no sales call to see a number.
