An RFQ, or request for quotation, gives a manufacturer the information needed to price a product, component, or manufacturing requirement. It may include engineering drawings, CAD files, specifications, quantities, materials, tolerances, and other requirements.
The RFQ process involves more than calculating a price. Teams need to review the requirements, understand what needs to be produced, assess the technical information, and determine the costs involved.
In manufacturing, the RFQ process can refer to both preparing an RFQ and responding to one. This blog focuses on the manufacturer’s side: reviewing an incoming RFQ, assessing the technical requirements, calculating costs, and preparing the final quote.
What Is the RFQ Process in Manufacturing?
The RFQ process in manufacturing is the series of steps a manufacturer follows after receiving a request for quotation and before sending a final quote to the customer.
The process typically involves reviewing the RFQ package, checking technical requirements, analyzing drawings and related documents, estimating costs, reviewing the proposed quote, and sending the final quotation.
The exact process varies by manufacturer, product, and project. A machining RFQ may require different technical information and cost considerations from an injection molding, fabrication, casting, or assembly RFQ.
The goal remains the same: understand what the customer needs, determine what it will take to produce it, and prepare a quote based on those requirements.
What Does a Manufacturing RFQ Include?
A manufacturing RFQ usually combines technical, quantity, quality, and commercial information. The technical package may include 2D engineering drawings, 3D CAD files, dimensions, tolerances, GD&T, material specifications, surface finish requirements, and other manufacturing requirements.
The RFQ may also specify:
- Part numbers and drawing numbers
- Drawing revisions
- Required quantities or production volumes
- Inspection requirements
- Certifications
- Delivery requirements
- Manufacturing or finishing requirements
- Project-specific notes
The exact information depends on the product and manufacturing process.
For example, a machining RFQ may place more emphasis on dimensions, tolerances, materials, and surface finishes, while an assembly RFQ may include additional components, BOM, and assembly requirements.
The important point is that the quote depends on the information behind the RFQ. If key technical information is missing, difficult to locate, or unclear, the quoting team may need clarification before it can complete the estimate.
Where Do Engineering Drawings Fit Into the RFQ Process?
Engineering drawings often provide the technical detail a manufacturer needs before it can determine what a job will cost.
A drawing does more than show the shape of a part. It can define dimensions, tolerances, materials, finishes, notes, quantities, and other requirements that affect how the part needs to be manufactured and inspected.
For the quoting team, this information helps answer practical questions:
- What needs to be produced?
- What materials and processes are required?
- Which requirements could affect cost, lead time, or inspection?
For example, a tolerance may affect machining or inspection. A material specification may affect purchasing and manufacturing. A drawing revision may change the scope that needs to be quoted.
This makes drawing review an important part of the RFQ process, especially when a quote depends on information spread across multiple drawings, revisions, and supporting documents.
How Does the RFQ Process in Manufacturing Work?
The RFQ to quote process can vary by manufacturer, product, and project. However, most manufacturing teams move through a similar sequence: understand the request, review the technical information, determine the costs, and validate the final quote.
1. RFQ Intake
The process starts when the manufacturer receives the customer’s RFQ and supporting documents. The team first needs to understand what the customer is requesting. This can include the part or product, required quantity, delivery expectations, and the documents supplied with the request.
At this stage, the team may also check whether the RFQ package contains the information needed for technical review.
For larger RFQs, this can mean working through multiple drawings, CAD files, specifications, and supporting documents before the technical review can begin.
2. Technical Review
Next, engineering, estimating, or quoting teams review the requirements. The team may check the drawings, specifications, CAD files, quantities, materials, tolerances, and other project requirements.
The purpose is to understand what the customer expects before the team starts building the cost. This step can also reveal missing information or questions that need clarification.
The team needs to establish what must be produced, which requirements must be met, and what information still needs confirmation.
3. Drawing Analysis
The quoting team then examines the engineering drawings and related technical information in more detail. Depending on the project, this can include reviewing:
- Part dimensions and geometry
- Material requirements
- Tolerances and GD&T
- Surface finishes
- Manufacturing notes
- Critical features
- Drawing revisions
- Required inspection or quality information
The goal is not simply to read the drawing. The team needs to understand which requirements could affect manufacturing and cost.
For example, a tighter tolerance may require additional machining or inspection. A special material or finish may introduce additional cost or lead-time considerations.
The team also needs to connect each requirement to the correct part, sheet, drawing, or revision. This becomes especially important when an RFQ contains multiple drawings or revisions.
4. Data Organization
Once the relevant information has been reviewed, the team needs to organize it for costing.
This may include quantities, part information, material requirements, manufacturing requirements, and other technical details. For manufacturers working with CAD assemblies, connecting components to existing part records can also help create a more consistent BOM for downstream work.
The team also needs to keep each detail connected to its source, especially when an RFQ contains multiple drawings, revisions, or related documents. This makes technical information easier to verify during costing and quote review.
5. Costing
The technical information now feeds into the costing process. Depending on the manufacturing operation, the team may consider material, labor, machine time, tooling, finishing, inspection, packaging, and other costs.
The engineering data helps define what needs to be produced and what requirements the manufacturing process must meet.
Costing therefore depends on both the quantity and the technical requirements behind that quantity. Those requirements can affect the resources, processes, and time needed to complete the work.
6. Quote Review
Before sending the quotation, the team reviews the proposed price and the assumptions behind it.
The review can include checking the quoted quantity, drawing revision, material, scope, manufacturing requirements, lead time, inspection requirements, and other commercial or technical conditions.
This review helps confirm that the quote reflects the latest RFQ requirements and the information used during costing.
It can also uncover differences between the information used during costing and the requirements shown in the latest drawing or supporting documents.
7. Final Quote
Once the technical and commercial review is complete, the manufacturer can prepare the final quotation.
The quote may include pricing, lead time, commercial terms, assumptions, exclusions, and other relevant information.
The final quote should reflect the requirements the team reviewed throughout the RFQ process.
What Drawing Information Can Affect a Manufacturing Quote?
Not every drawing detail affects price in the same way. Some requirements have a direct impact on production costs, while others affect inspection, lead time, or manufacturing feasibility.
1. Dimensions and Geometry
Part size and geometry can influence the machines, tools, processes, and setup required for production. Complex features may require additional operations or specialized equipment. Large or unusual dimensions can also affect material usage and production capacity.
2. Materials and Finishes
Material selection can have a direct effect on the cost of a part. The required grade, availability, and quantity can all influence the estimate. Surface treatments and finishes may also require additional processing, inspection, or external suppliers.
3. Tolerances and GD&T
Tolerances define how closely a manufactured part must meet its specified dimensions. Tighter tolerances can require additional machining, measurement, or quality checks. GD&T can also add manufacturing and inspection requirements that estimators need to consider when preparing a quote.
4. Quantities
Order quantity affects how suppliers plan production. A larger order may spread setup costs across more units, while a small batch may require a different production approach. The requested quantity can therefore affect both total cost and unit pricing.
5. Revisions and Notes
Drawing revisions can change the requirements used for costing. A new revision may introduce different dimensions, materials, features, or manufacturing notes. Reviewing the current revision helps prevent estimators from using outdated information when preparing a quote.
Challenges in the Manufacturing RFQ Process
Manufacturing teams often handle RFQs with large amounts of technical information. The challenge is not always the complexity of the final calculation. It can also be the time required to review and verify the information beforehand.
Large drawing packages can contain many sheets, while important requirements may appear in different locations. Multiple revisions can make it harder to confirm which information applies to the current request.
Teams may also need to compare drawings with specifications, spreadsheets, emails, or other documents. When information is spread across these sources, manual review can take significant time and make it harder to confirm which details apply to the current RFQ.
These challenges do not remove the need for engineering or estimating judgment. They create opportunities to reduce the manual work around that judgment.
How Can AI Support the RFQ to Quote Process in Manufacturing?
AI can support parts of the RFQ to quote process by helping teams process and review technical information.
For engineering drawing data, AI can help identify relevant information such as quantities, drawing elements, revisions, specifications, and other details that support the quoting process.
It can also help teams work through large drawing packages more efficiently. Instead of manually searching every document for each piece of information, the team can use AI-assisted results as a starting point for review.
For example, AI can support drawing analysis, quantity extraction, revision comparison, and source-based information retrieval.
This can reduce repetitive work involved in locating and organizing technical information while keeping the review with the people responsible for the estimate.
The important distinction is that AI supports the review process. The quoting or engineering team still needs to validate the information, consider the manufacturing context, and make the final pricing decision.
AI Blueprint Classifier for Manufacturing Quoting
The biggest challenge in manufacturing quoting is often not calculating the final price. It is getting the right engineering information in front of the people who need to price the work.
The engineering drawing intelligence platform, AI Blueprint Classifier, helps manufacturers turn drawing packages into reviewable, source-connected information for the quoting process. It can read part drawings, identify dimensions, materials, finishes, quantities, GD&T, BOM information, and cost-relevant features, while keeping the results connected to the original drawing.
That gives quoting teams a faster way to work through an RFQ. Instead of repeatedly searching across drawings for the details that affect cost, they can review the relevant information and focus on the requirements that need engineering or estimating judgment.
From Drawing Review to Quote Review
For manufacturing RFQs, AI Blueprint Classifier can help teams:
- Review drawings faster: Find part information, specifications, and cost-relevant features across drawing packages.
- Surface cost drivers: Identify tight tolerances, special finishes, secondary operations, and inspection requirements that can affect costing.
- Organize BOM information: Reconcile components across multi-sheet assemblies and prepare structured BOM data for downstream use.
- Check revisions: Compare drawing versions and identify changes that may affect the current quote.
- Find answers across drawing packages: Search drawing information in plain English and trace answers back to the relevant source location.
- Support quote preparation: Bring quantities, costs, and specifications together in a structured estimate that the quoting team can review.
The result is less time spent locating and re-entering engineering information and more time spent reviewing what it means for the quote.
AI Blueprint Classifier keeps the source drawing at the center of that process. Results can be traced back to the relevant drawing location, giving engineers and estimators a way to verify the information before using it in costing and quotation decisions.
This helps manufacturers move from an incoming RFQ to a reviewable technical and cost picture with less repetitive drawing work.
Conclusion: RFQ Process in Manufacturing
The RFQ process in manufacturing starts with a customer request, but the work behind the quote often depends on detailed technical information.
Drawings, CAD files, specifications, quantities, tolerances, materials, and quality requirements help define what the manufacturer needs to price. That information supports technical review, costing, and final quote review.
AI can support this process by helping teams work through technical drawing information, locate relevant details, compare revisions, and prepare information for review.
The opportunity is not simply to automate quoting. It is to make the technical information behind each quote easier to review and verify.
