How to Write an RFQ That Gets You Accurate Quotes (Not Guesses)
By The Vrocure Team · 2026-07-02 · 7 min read
A request for quote is the single most important document in your sourcing process — and most of them are missing the information a supplier needs to give you a real number. When a shop cannot answer a question, they do one of two things: pad the price to cover the risk, or email you back and wait. Both cost you days.
A good RFQ removes ambiguity. Here is how to write one that earns fast, accurate, comparable quotes.
What every manufacturing RFQ must contain
These are the fields a machinist or estimator opens first. Leave any of them blank and you are inviting an assumption.
- Quantity and cadence. One-off, batch of 50, or 500/month on a blanket order? Unit price changes completely with volume, and shops schedule capacity around cadence.
- Material and grade. "Aluminium" is not a spec. 6082-T6 and 7075-T6 cost and machine differently. Name the alloy, temper, or plastic grade.
- Drawings with tolerances. A 2D drawing (PDF or STEP) with dimensioned tolerances. A model alone tells the shop the shape, not which features are critical.
- Surface finish and treatment. Anodising, powder coat, plating, bead blast, as-machined — finish can be a third of the part cost.
- Target lead time. "ASAP" is not a date. Give a need-by date so shops can quote standard vs. expedite.
- Delivery location and Incoterms. Where it ships and who owns freight and duty.
- Inspection and documentation. First-article inspection, material certs, PPAP level, CoC — say so up front, because it changes the price.
The four mistakes that inflate every quote
1. Sending a model without a drawing
A STEP file shows geometry, not intent. Without dimensioned tolerances the shop cannot tell a ±0.005 mm bore from a ±0.5 mm clearance hole — so they machine everything to the tightest reasonable tolerance and you pay for precision you did not need.
2. Over-tolerancing "just to be safe"
Tight tolerances feel responsible. They are also the fastest way to double a price. Every tenth of a thousandth adds setup, slower feeds, and inspection time. Tolerance the features that matter and open up the ones that do not.
3. Hiding the quantity
Buyers sometimes withhold volume hoping for a keener price. It backfires — the shop quotes for the worst case (a one-off) because that is all they can see. Share real quantities and let amortised setup work in your favour.
4. Leaving finish and inspection to the end
Finish, certs, and inspection are not afterthoughts; they are cost drivers. Deciding them after the quote means a revised quote, another round-trip, and a slipped date.
A copy-ready RFQ checklist
- Part name, revision, and drawing number
- Quantity + expected reorder cadence
- Material, grade, and temper
- Dimensioned drawing (PDF) and 3D model (STEP)
- Critical-to-function features called out
- Surface finish and any coating/treatment
- Inspection, certs, and documentation requirements
- Need-by date and delivery location + Incoterms
- A single point of contact for technical questions
Make quotes comparable, not just accurate
Accuracy gets you a real number. Comparability lets you decide. If every supplier quotes against the same structured RFQ — same fields, same drawing, same terms — you can put bids side by side on price, lead time, and quote quality instead of untangling five different email formats. That is the difference between negotiating and guessing.
Vrocure structures every RFQ into the same fields, runs a Dr. Review manufacturability check on your drawing, and returns bids you can compare on one screen — with supplier identity blind so pricing stays honest. You can start free and send your first RFQ the same morning.
