Most teams researching OpenBOM alternatives aren't looking to replace a CAD-driven product lifecycle management (PLM) system they want BOM management without per-user pricing, and they want their bill of materials connected to inventory they can actually act on. OpenBOM is strong for engineering teams syncing CAD data, but its per-seat cost adds up fast once purchasing, warehouse, and operations staff need access and unlike StockFlow's ongoing free Starter plan, OpenBOM's free or trial access is limited.
StockFlow is built for that gap: a free Starter plan with multi-level BOM support, real-time stock tracking, native barcode scanning, and purchase orders all in one tool, with no separate PLM license needed for everyone who touches the BOM.
StockFlow vs OpenBOM: Feature Comparison
| Category | StockFlow | OpenBOM |
|---|---|---|
| Pricing model | Free Starter plan, no per-seat PLM fee | Per-user subscription, cost climbs fast with team size |
| Setup complexity | Sign up and start in minutes | CAD integration and catalog setup often need onboarding time |
| BOM management | Multi-level BOM tied directly to live stock counts | Strong multi-level BOM and revision/version control |
| Inventory tracking | Native real-time stock levels, locations, and reorder points | Inventory add-on layered on top of BOM/PLM core |
| Barcode scanning | Built-in mobile scanning for receiving, picking, and counts | Not a core focus primarily catalog and BOM data |
| Purchasing & POs | Built-in purchase orders tied to supplier and stock data | Available, but secondary to BOM/PLM workflows |
| CAD/PLM depth | Light manufacturing focus, not a CAD data management system | Deep CAD integrations (SolidWorks, Onshape, etc.) and PLM workflows |
| Best fit | Small manufacturers and distributors who need BOM + inventory in one place | Engineering teams managing CAD-driven product data and part catalogs |
How to Switch From OpenBOM to StockFlow
- 1
Export your BOM and part data from OpenBOM
Export your bill of materials, part catalog, and supplier data from OpenBOM as CSV. StockFlow's import tool accepts standard CSV exports for products and components.
- 2
Import products and BOM structure into StockFlow
Upload your export and map fields (SKU, part name, quantity, supplier) so your existing multi-level BOM structure carries over without manual re-entry.
- 3
Connect inventory and stock locations
Add your current stock counts and warehouse locations so BOM components are tied directly to real-time inventory, not a separate catalog.
- 4
Train your team and go live
Most teams switching from OpenBOM to StockFlow are live within a week, with barcode scanning and purchasing ready from day one.
StockFlow Pros / Cons
- Pros: Free plan with BOM, inventory, purchasing, and barcode scanning together.
- Pros: No per-user PLM fee affordable as your team grows.
- Cons: Not a CAD data management system no SolidWorks/Onshape sync.
- Cons: Lighter revision/version-control depth than a dedicated PLM tool.
OpenBOM Pros / Cons
- Pros: Deep CAD integrations and strong part-catalog/PLM workflows.
- Pros: Built for engineering teams managing complex product data.
- Cons: Per-user pricing scales quickly once non-engineering staff need access.
- Cons: Inventory and purchasing are secondary to its BOM/PLM core.
Who Should Switch to StockFlow?
Switching makes sense if your priority is connecting BOM data to real stock levels, purchasing, and warehouse execution and you don't need deep CAD synchronization. This fits small manufacturers, assemblers, and distributors who build or kit products and want one tool for BOM and inventory, without paying for a seat-based PLM license for every person who touches the data.
Staying on OpenBOM makes sense if your team is engineering-led and relies on tight CAD integration (e.g., SolidWorks, Onshape) to keep part data and revisions in sync automatically. For a full breakdown of StockFlow's BOM features, see our free bill of materials software guide.
