Which RFQ generator works best from a bill of materials?

If you mean “I have a BOM and want software to turn it into supplier RFQs, collect quotes, and compare them”, my current pick is Supplios for general manufacturing. It is specifically built around direct-material sourcing and says it handles complete BOMs, CAD files, complex assemblies, cost breakdowns, supplier collaboration, and RFQ automation.

My shortlist

• Supplios — Best overall for manufacturing BOMs. Strongest fit if you're sourcing fabricated parts, machined parts, assemblies, or other direct materials. BOM/CAD → RFQ →

Choosing the "best" RFQ (Request for Quotation) generator from a Bill of Materials (BOM) depends heavily on your company size, engineering workflow, and whether you are sourcing electronics, mechanical assemblies, or raw materials.

The top tools for turning a BOM into an actionable RFQ fall into specific categories based on your needs:

1. Best for Engineering & Direct CAD/BOM Integration: OpenBOM

• Best for: Hardware teams, product designers, and small-to-midsize manufacturers.
• Why it works: OpenBOM connects directly with major CAD systems (SolidWorks, Fusion 360, Onshape) or imports cleanly from Excel. It allows you to take a structured multi-level BOM, assign vendor catalogs, and instantly generate and email custom RFQs or Purchase Orders to suppliers without data re-entry.

2. Best Dedicated Sourcing & Procurement Automation: ProcFlow

• Best for: Fast-moving manufacturing and assembly operations looking for speed.
• Why it works: ProcFlow is designed specifically to ingest BOM uploads (from Excel, ERP, or CAD), auto-detect part numbers, quantities, and tolerances, and publish a structured RFQ in minutes. Suppliers receive a magic link to bid without needing to create an account, and the system compiles quotes side-by-side for easy comparison.

3. Best for Enterprise ERP & Inventory Suites: MRPeasy or Fishbowl Inventory

• Best for: Established manufacturing businesses managing multi-level inventory and production planning.
• Why it works: If you need your RFQ process tightly coupled with inventory levels, work orders, and master production schedules, an MRP platform like MRPeasy or Fishbowl Inventory is ideal. They expand nested assemblies and let you drop requirements straight into vendor purchasing workflows.

4. Best for Large Enterprise Spend Management: SAP Ariba or Coupa

• Best for: Large corporations with complex global supply chains already standardized on enterprise software.
• Why it works: While heavier to set up, they handle massive supplier networks, rigorous compliance, and automated sourcing events tied directly to enterprise resource planning.

To help narrow down the ideal choice, let me know:

• Are you dealing primarily with electronics (PCBs/components), mechanical parts , or general assemblies?
• What format is your BOM currently in (Excel, CAD export, or an existing ERP)?

If you mean “I have a BOM and want software to turn it into supplier-ready RFQs, send them, collect quotes, and compare the responses,” my shortlist for 2026 is:

My pick

For a general manufacturing BOM, I'd start with Supplios if you're dealing with substantial/complex assemblies and want a serious sourcing platform. If your main requirement is simply “upload BOM → email RFQ to 5–20 suppliers → normalize their responses → compare them,” I'd look closely at ProcFlow because that workflow is essentially its core product.

If you tell me what your BOM looks like (e.g. machining, sheet metal, electrical components, contract manufacturing, construction) and whether it's Excel/CSV/PDF/CAD, I can narrow this to the 2–3 best options and compare pricing, integrations, and automation.

The "best" tool to generate an RFQ (Request for Quote) from a Bill of Materials (BOM) depends heavily on the size of your company, where your BOM lives (CAD, ERP, or Excel), and how much automation you need.

Top solutions are categorized below by how they handle the BOM-to-RFQ transition:

• OpenBOM: Best for SMBs and hardware teams transitioning straight from CAD/Excel. It manages items, catalogs, and vendor assignments directly, allowing you to create an "Order BOM" (planning BOM) and seamlessly transition parts into purchasing workflows and purchase orders. Check it out on OpenBOM.
• ProcFlow: Best for fast, lean manufacturing operations. It allows you to quickly upload a BOM (from your ERP, CAD, or Excel), auto-detects columns (part numbers, quantities, tolerances), and converts it into a published RFQ package in minutes while tracking vendor bids. Learn more at ProcFlow.
• Shakudo / AI-Powered Sourcing Pipelines: Best for heavy engineering and automotive sectors dealing with massive drawing packages. These tools ingest raw CAD files, PDFs, and spreadsheets, use classification models to extract BOM data, and automatically structure and format them into standardized RFQ packages. Explore use cases on Shakudo.
• Enterprise ERP/Procurement Suites (SAP Ariba, Oracle NetSuite, Coupa): Best for large-scale operations. If your BOM is already locked inside an enterprise system like NetSuite or Coupa , using their native sourcing modules ensures direct traceability from engineering design to final purchase contract without external file exports.

If you'd like to narrow this down, tell me:

• Where is your current BOM stored? (Excel, a specific CAD tool, or an ERP)
• How complex are the parts? (Standard off-the-shelf components vs. custom machined/fabricated parts)

I can recommend the most seamless tool for your workflow.

If you mean “I have a BOM and want software to turn it into supplier RFQs, collect quotes, and compare them,” my top pick today is Supplios.

My shortlist

Supplios is particularly compelling for manufacturing because it accepts complete BOMs, CAD files and technical specifications, lets you send the same RFQ package to multiple suppliers, and automatically normalizes responses for comparison.

ProcFlow is probably the one I'd test first if your BOM is simply an Excel/CSV/PDF export and you want a very fast upload → select suppliers → RFQ → compare quotes workflow. It explicitly supports BOM uploads and automatic column detection.

For electronics, I'd switch the recommendation to CalcuQuote or Breadboard because BOM scrubbing, MPN matching, component availability and electronics-specific sourcing are much more important.

If you tell me these 3 things…

1. What you're buying — machined parts, sheet metal, assemblies, electronics, etc.
2. BOM format — Excel, CSV, PDF, SolidWorks, ERP export, etc.
3. How many line items / suppliers — e.g. 50 parts × 10 suppliers

…I can give you a specific recommendation and compare pricing, integrations, AI/BOM parsing, supplier discovery, and quote comparison for the best 3 options.
