Every estimator has a stack of RFQs they wish they had never touched — the drawing that took two days to interpret and lost on price, the customer who haggled the margin to zero, the "simple" part that turned out to need a process the shop does not run. Knowing when to decline an RFQ is not defeatism; it is one of the most profitable skills a small shop can build. Every hour spent quoting a job you will not win, or worse one you win and regret, is an hour stolen from a bid you could have landed at a healthy margin.
Most shops treat the inbox as a queue to be cleared: every RFQ gets a number, because saying no feels like leaving money on the table. But quoting is not free. It consumes your scarcest resource — skilled estimating time — and a "yes" to a bad RFQ is a quiet "no" to a better one you never got to. This article gives you a practical framework for spotting the RFQs that are not worth your time, and a clean way to decline them without burning the relationship.
The hidden cost of a quote you should have declined
Before you can decide what to skip, you have to price your own quoting time. Estimating is not overhead you can ignore — it is paid labor, often your most experienced person, pulled off the floor or the next bid.
A worked example. Say a thorough quote on a moderately complex machined part takes 3 hours: reading the drawing, pulling material, building operations, checking the queue, writing it up. If your estimator's loaded cost is the same as a senior machinist — roughly in line with the figures in our machine shop hourly rate breakdown — that quote costs you real money before a single chip is cut.
| RFQs quoted/week | Hours each | Hours/year on quoting | At ~€60/hr loaded |
|---|---|---|---|
| 5 | 3 | ~750 | ~€45,000 |
| 10 | 2 | ~1,000 | ~€60,000 |
| 15 | 1.5 | ~1,150 | ~€69,000 |
That is the annual cost of your quoting capacity. If a quarter of those hours go to RFQs you had no real chance of winning, you are burning five figures a year on bids that were never yours. Declining the wrong RFQs is not lost revenue — it is redirected capacity toward the ones you can actually convert.
The red-flag table: what to watch for
Most decline-worthy RFQs announce themselves early if you know the signals. They split into commercial flags (the deal is bad for you) and technical flags (the part is wrong for your shop).
| Red flag | Type | Why it warns you off |
|---|---|---|
| "Send your best price" with no other vendor info | Commercial | You are likely column fodder for a price check on the incumbent |
| Quantity of 1–2 on a part needing heavy setup | Commercial | Setup cannot amortize; your price looks absurd vs. a shop tooled for it |
| Buyer won't share target price or budget at all | Commercial | Often a fishing expedition, not a live order |
| Net-90 terms or vague payment language | Commercial | You finance their cash flow; margin must cover the risk |
| Tolerances tighter than your process holds | Technical | You bid blind, then scrap or sub it out at a loss |
| A process you don't run (e.g. grinding, plating) | Technical | The sub-out kills margin and you own the quality risk |
| Material you've never sourced | Technical | Lead-time and price guesses turn into surprises |
| Incomplete drawing, no GD&T, "quote from the photo" | Technical | You are quoting assumptions, not a part |
None of these is an automatic no. A net-90 customer who fills your idle third shift may be worth it; a tight tolerance you can hold with a quick fixture change may be fine. The flags tell you where to look harder, not what to decide.
A 60-second no-bid score
Gut feel works for veterans, but it does not transfer to a junior estimator and it does not get measured. A lightweight score makes the call repeatable. Rate each factor 1 (bad) to 5 (good), then add them up.
- Fit — is this squarely in your shop's wheelhouse? (process, size, material)
- Winnability — do you have a real shot, or are you the backup vendor?
- Margin headroom — can this carry your target margin, or is it a price war?
- Quantity / repeat potential — one-off, or a door to recurring work?
- Drawing completeness — can you quote the real part, or are you guessing?
- Capacity fit — does it land in a slot you actually want to fill?
A total of 24–30 is a clear bid. 18–23 means bid only if capacity is loose. Below 18, decline — or requalify the RFQ before you spend the hours. The exact thresholds matter less than the discipline: every RFQ gets the same six questions, and the weak ones stop quietly eating your week. Fold this directly into your RFQ workflow so the score happens at intake, not after three hours of work.
Technical red flags that deserve a hard look
The expensive mistakes are usually technical, because they hide until the part is on the machine. A drawing that calls out a ±0.005 mm tolerance on a feature your shop routinely holds to ±0.02 mm is not a stretch — it is a different class of work, with different inspection and likely a different machine. Quoting it as if it were ordinary work means you either lose on price to a shop built for it, or win and discover the scrap rate in production.
The same goes for processes you do not own. Sending heat treatment, plating, or grinding to a sub means you carry the lead-time risk, the quality risk, and the markup squeeze — all on a job that was never fully yours. If you are unsure whether a tolerance is a cost driver or just noise, the patterns in GD&T for estimators help you read the drawing before you commit. And an RFQ with no GD&T, a missing view, or "just quote from the photo" is not a real package — it is a request to quote your assumptions, and assumptions are where margin goes to die.
Commercial red flags: when the deal is the problem
Some RFQs are technically perfect and still not worth winning. The classic is the buyer who wants only a price — no drawing questions, no interest in lead time, no conversation. That buyer is almost always benchmarking their incumbent, and you are the free third quote that pressures the supplier they intend to keep. You can spot it because they resist every qualifying question; a real buyer engages.
Watch the economics, too. A quantity of one on a part that needs four hours of setup will always look overpriced next to a shop already tooled for it — the setup has nowhere to amortize, a dynamic the pricing CNC machined parts guide lays out in detail. And payment terms are part of the price: net-90 on thin margin means you are financing the customer's working capital for a quarter. If the margin does not cover that, the "win" costs you cash flow you cannot spare.
How to decline without burning the bridge
Declining well is a relationship skill, not a brush-off. A fast, honest no is worth more to a buyer than a slow, padded quote you never intended to win — it respects their timeline and keeps you on the list for work that does fit. Three patterns work:
- The clean no-bid. "Thanks for the opportunity — this one isn't a fit for our shop, but please keep us in mind for milled aluminum work in the 50–500 range." Specific, so they remember what to send you next time.
- The referral. Point them to a shop that does fit. Buyers remember who saved them a week of searching, and it costs you nothing.
- The conditional bid. Sometimes "decline" really means "quote it differently." Offer the larger batch where setup amortizes, propose a tolerance you can actually hold, or quote your standard lead time instead of their rushed one. You have turned a likely loss into a deal on your terms.
A firm date you can defend beats an optimistic one you will miss — the logic in lead-time estimation applies to the conditional bid as much as to the quote itself.
Let the drawing tell you fast — then decide
Most of the cost of a bad RFQ is incurred before you decide to decline it: the hours spent reading the drawing and building the quote happen first, and only then do the red flags surface. The leverage is in front-loading that read so the no-bid call is cheap.
QuoteBuddy reads the technical drawing and surfaces material, dimensions, tolerances, and operations in minutes — so you can score fit, winnability, and the tolerance red flags before you sink half a day into a quote you should have skipped. For the RFQs that pass, it builds the itemized price from your machine rates and target margin; for the ones that don't, you have lost minutes, not hours. Either way you get your most expensive resource — estimating time — back.
Start a 30-day trial and run your next week of RFQs through it. The ones worth winning get quoted faster; the ones worth declining cost you almost nothing to identify.
