Quoting Multi-Source RFQs Efficiently

Your shop does CNC well. Maybe you’ve added 3D printing. Perhaps you partner with a sheet metal vendor down the road. Individually, each process has a quoting workflow you trust. Then a customer sends one RFQ that needs all three — five machined brackets, two printed jigs, and a sheet metal enclosure — due in two weeks.

Suddenly you’re juggling three quoting engines, two external vendor emails, and a spreadsheet that’s already out of date before you hit send. The customer waits. Your margin guesses get wider. And the shop floor wonders why the job packet looks like a collage.

Why Multi-Source RFQs Break Standard Workflows

Most quoting tools assume a single process per quote. They’re built around one material library, one machine rate card, one setup logic. When a job crosses process boundaries, the cracks show:

• Inconsistent cost models: CNC quotes run on cycle time and tooling. Additive quotes on material volume and machine hours. Sheet metal on flat pattern nesting and bend count. Merging them manually invites arithmetic errors.
• Disconnected lead times: The CNC side says three days. The print farm needs two days plus post-processing. The sheet metal vendor quotes five days. The customer gets one delivery date — the longest path — but you’ve padded each leg differently.
• Version control drift: The customer revises the enclosure thickness. You update the sheet metal calc. Did the CNC bracket mounting holes move? Did the printed jig clearance change? If those updates live in separate files, something gets missed.
• Margin leakage: You pad the total 15% to be safe. The customer pushes back. You cut the pad to 8% and hope the print farm doesn’t have a build failure. That’s not pricing — that’s gambling.

What a Unified Quote Looks Like

A multi-source quote shouldn’t be a stitched-together PDF. It should behave like a single engineered estimate:

• One bill of operations: Every line item — machine setup, material, labor, post-processing, QA, packaging — lives in one structured list, tagged by process and owner (in-house or vendor).
• Shared design inputs: The CAD model or drawing set feeds all three process calculations. A hole diameter change propagates to the CNC cycle time, the printed jig clearance, and the sheet metal flat pattern automatically.
• Consolidated timeline: A critical-path view shows which process gates the delivery date, where float exists, and what happens if the print farm slips by 24 hours.
• Roll-up pricing with transparency: The customer sees one total. You see the build-up: in-house CNC at your shop rate, additive at your printer rate, sheet metal at vendor cost plus your management markup. No hidden buffers.

Structuring the Data So It Scales

You don’t need a new ERP to make this work. You need a quoting data model that treats process as an attribute, not a silo. Start with these fields on every line item:

• Process type (CNC, FDM, SLS, laser cutting, bending, etc.)
• Execution owner (internal machine group, external vendor ID)
• Rate basis (machine hour, material kg, flat pattern area, setup event)
• Dependency links (e.g., printed jig must complete before CNC inspection)
• Revision stamp (last CAD hash or drawing revision that touched this line)

With that structure, a single RFQ becomes a filtered view: show me all CNC lines, show me all vendor lines, show me the critical path. The math stays the same; the reporting gets useful.

Handling External Vendors Without Email Ping-Pong

Sheet metal and specialty finishing often live outside your four walls. The trick is giving vendors a structured way to respond — not a blank email thread. Two practical approaches:

1. Vendor portal lite: Send a secure link with the part spec, material, qty, and your required lead time. The vendor fills in their price, capacity confirmation, and any DFM notes. You get structured data back, not a paragraph you have to parse.
2. Pre-negotiated rate cards: For repeat vendors, agree on rate formulas (e.g., $/sq ft of flat pattern + $/bend + setup fee). When the RFQ lands, you apply their card instantly and only flag exceptions. Saves hours on both sides.

Either way, the vendor’s response becomes just another line item in your unified quote — auditable, versioned, and part of the roll-up.

Communicating One Price, One Date, One Risk Profile

The customer doesn’t care about your internal complexity. They want:

• A single price they can PO against
• A delivery date with a confidence level
• Visibility into what happens if something slips

Your quote package should lead with the summary: total price, ship date, payment terms. Then offer drill-down: process breakdown, vendor names (if not confidential), critical path, and your contingency plan for the longest lead item. That transparency builds trust — and reduces back-and-forth negotiations.

Where Solvi Fits

Solvi’s quoting engine is built for exactly this: multiple processes, internal and external, rolled into one quote with a single data model. You define rate cards per process, link vendors with their own cards or portal access, and the system maintains the critical path as revisions hit. The shop floor gets one job packet. The customer gets one professional quote. See how it works.

Start With Your Next Messy RFQ

Don’t rebuild your whole workflow tomorrow. Take the next multi-source RFQ that lands in your inbox. Build the unified line-item list in a spreadsheet if you have to. Tag each line by process and owner. Calculate the critical path manually once. You’ll see where the friction lives — and where a purpose-built tool pays for itself in a single job.
