Manufacturing RFQ checklist

NIST MEP's Supplier Scouting form separates an opportunity into general, technical, business, and attachment sections. Its technical fields include process, dimensions, tolerances, performance specifications, materials, certifications, and regulations. Business fields cover volume, target price, delivery, and packaging. That is a sound model for a website RFQ too.

Start with the application

Ask what the buyer is making and where this component sits in the assembly. The answer helps engineering recognize a missing load, temperature, fluid, electrical, cosmetic, or regulatory requirement. It also gives sales enough context to route the request to the right process owner.

Keep the first screen short. Company, contact, part name, application, requested process if known, prototype or production stage, and the target date are enough to open the record. Do not force a buyer to finish a long form before the system saves anything.

The form should say when a field is optional. A buyer who does not know the process should be able to describe the application and ask for engineering input.

Identify the controlled files

Request a 3D model when geometry drives the quote. Ask for a 2D drawing when it carries tolerances, threads, surface finish, inspection notes, or other requirements that are not reliable in the model alone. Assemblies may need a bill of materials, statement of work, and drawings for individual parts.

Xometry's production RFQ page asks for part files, statements of work, bills of materials, drawings, written specifications, process, material, quantity, certification, inspection, and delivery requirements. Protolabs' sheet-metal guidance shows why file roles matter: some features can come from a 3D model, while threaded holes and other instructions may require a 2D drawing.

Give every upload a file name, revision, and date. Ask the buyer which document controls if the model and drawing disagree. The estimator should see that answer beside the files, not inside a later email chain.

Capture material and finish precisely

“Aluminum” is incomplete. Ask for the alloy or specification, temper when relevant, approved substitutions, finish, color, coating thickness if controlled, and any material certification requirement.

If the buyer allows alternatives, record the reason. An alternative may be acceptable for a prototype and prohibited for production. Keep “supplier may suggest” separate from “supplier may substitute without approval.”

Protolabs lets buyers change material, quantity, and turn time inside a quote. That convenience still depends on a defined selection. A default material may produce a number, but it does not establish that the number fits the application.

Put tolerances next to the features they control

Ask for general tolerances and feature-specific tolerances. Include geometric dimensioning and tolerancing, surface roughness, threads, inserts, weld requirements, and mating features when they apply.

Avoid a form that asks only for “tightest tolerance.” The estimator needs to know which feature carries it and how the part will be inspected. A tolerance on every dimension can raise cost without improving function. Engineering should be able to flag that before price becomes a promise.

When a drawing is missing, the intake can ask whether standard shop tolerances are acceptable. It should not invent a tolerance or turn a blank field into consent.

Separate sample quantity from production demand

Collect prototype quantity, first production quantity, expected annual volume, lot size, and any release schedule. These numbers affect setup, tooling, material buying, inspection, packaging, and capacity.

For scheduled releases, ask for the quantity in each shipment and the required dates. Protolabs' production guidance treats batch size and shipping frequency as separate inputs. NIST MEP also distinguishes business volume from delivery and packaging requirements.

Target price can be useful when it represents a commercial limit. Label it as a target and let the estimator explain which specification or volume assumption prevents it.

State quality and compliance requirements before pricing

Ask whether the buyer requires a certificate of conformance, material certification, first article inspection, dimensional report, source inspection, traceability, special-process records, or a named quality standard. Export restrictions and regulated applications need an explicit route to trained staff.

Do not make the chatbot decide whether a part is ITAR-controlled, medical, aerospace, food-contact, or otherwise regulated. It can collect the buyer's statement and stop ordinary automation. A qualified person should review the files, facility requirements, data handling, and contract terms.

The quote should identify what inspection and documentation are included. “Quality included” is too vague to price or accept.

Get delivery and packaging into the same record

Ask for the ship-to location, required arrival date, split shipments, packaging, labeling, and carrier or account constraints. Record whether the date is requested, required, or flexible.

A lead time without a starting event causes arguments. State whether the clock begins at purchase order, final drawing approval, material receipt, tooling approval, or another agreed milestone.

If the buyer asks for an impossible date, preserve the date and route the request. Do not silently replace it with the normal lead time.

Use progressive disclosure

A website RFQ should open a valid sales record before asking for every engineering detail. Save the contact and application first. Then show process-specific questions after the buyer selects machining, sheet metal, molding, fabrication, or “not sure.”

Uploads need size and format guidance, malware scanning, access controls, and a retention rule. The confirmation should list received files and missing items. Send the same list to the assigned estimator.

Automation may check whether required fields exist, detect an unreadable file, or identify a missing revision. It should not approve manufacturability, regulatory status, or final price. Those decisions belong to the manufacturer.

Define what counts as quote-ready

Use three states: received, needs clarification, and ready for estimating. A request becomes quote-ready only when the assigned person confirms that the commercial and technical package is sufficient for the proposed scope.

Track the reason when an RFQ stalls. Missing drawing, unclear tolerance, unknown material, certification question, volume conflict, and delivery conflict are useful categories. They show which website fields deserve revision. They also stop marketing from celebrating form submissions that engineering cannot quote.

DATIK's Lead Chatbot can collect the first RFQ fields, accept approved attachments, create one CRM record, and transfer the package to a named person. The ownership terms cover accounts, configuration, and exports. A free diagnostic can map one RFQ from website arrival to engineering acceptance before the form is rebuilt.
