Instant quoting is software that prices a manufactured part from its 3D file in seconds, using the shop’s own machines, materials, rates and rules, so the buyer sees a price and can order without waiting for an estimator. It works well for parts the shop makes routinely and whose cost the geometry largely decides. A person should still review jobs where a drawing note, a tight tolerance, an unusual material or a large order changes the cost in ways the file cannot show.
Key points
- An instant quote is computed, not guessed: geometry analysis, then the shop’s cost model, then its rules.
- The price is only as good as the rates and times behind it, so they need checking against real jobs.
- It fits repeatable processes and well-defined options; it struggles with drawings, assemblies and edge cases.
- Good systems route the edge cases to a person instead of pricing them badly.
- A buyer-facing price should explain itself, with manufacturability warnings shown before the order.
How does instant quoting work?
Behind the price box there are four steps, whatever the process.
- The file is analysed. The software reads the model and measures what drives cost: volume, surface area, bounding box, wall thickness, overhangs, holes and, for printing, the cross-section at each layer. This step is the expensive one and happens once per file.
- Manufacturability is checked. DFM checks flag walls that are too thin, parts that do not fit the machine, trapped volumes and features that cannot be made as drawn.
- The buyer configures. Material, colour, finish, quality, quantity and lead time. Each change re-prices the part from the same analysis, so it takes milliseconds, not another upload.
- The cost model prices it. The shop’s rates turn the measurements into material, machine time, labour, set-up and finishing, then the shop’s rules add minimums, quantity breaks and margin.
The output should be a price breakdown, not a single number: a shop needs to see why a part costs what it does, and the buyer needs to see at least the parts of it that are theirs to change.
Instant quoting compared with a manual quote
| Manual quote | Instant quote | |
|---|---|---|
| Who does the work | An estimator | Software, with a person for exceptions |
| Time to price | Minutes to days, depending on the queue | Seconds |
| Consistency | Varies with the estimator and the day | Same inputs, same price |
| Handles drawing notes | Yes | Only what the options capture |
| Handles odd jobs | Yes, with judgement | Should route them to review |
| Buyer can try options | Only by asking again | Yes, instantly |
| Cost to the shop per quote | Estimator time | Close to zero once set up |
The manual quote remains better at judgement. The instant quote is better at speed and consistency. The practical question is which of your requests need judgement and which only need arithmetic.
What does slow quoting cost a shop?
The cost is mostly time, and it is easy to work out for your own shop.
Worked example: estimator time on routine requests (example figures)
| Line | Calculation | Amount |
|---|---|---|
| Requests per week | example shop | 40 |
| Time per routine quote | read, price, write, send | 20 min |
| Estimator time per week | 40 × 20 min = 800 min | 13 h 20 min |
| Share of a 40-hour week | 13.33 h ÷ 40 h | one third |
The less visible cost is in the buyer’s waiting. A buyer with a deadline may well order from the first credible answer, so a slow quote can lose the job before anyone compares prices. Track your win rate against response time to see whether that holds for your customers; quote win rate explains how to measure it.
When does instant quoting fit?
It fits best where the geometry and a handful of options decide most of the cost.
- 3D printing. FDM, resin, SLS and MJF are close to the ideal case: no tooling, set-up is small or shared, and print time and material can be computed from the geometry. The work is in measuring properly; 3D printing cost calculation shows what that involves.
- Sheet cutting. Laser, waterjet and plasma prices follow cut length, pierce count and material area, all readable from a flat pattern.
- Routine CNC work. Prismatic parts in common materials with standard tolerances can be estimated well from a solid model, though machining estimates carry more uncertainty than printing ones.
- Repeat buyers. Engineers who reorder variants of the same part save the most time.
When should a person still review?
Instant quoting should not mean every request gets an automatic price. Good systems recognise their limits and send the request to a person, either before showing a price or before accepting the order.
| Trigger | Why it needs a person |
|---|---|
| Tolerances tighter than the shop’s standard | Extra operations, inspection and scrap the file does not show |
| A drawing with notes, threads or finishes | Requirements outside the 3D model |
| Large quantities | Better routes, fixtures or material deals than the model assumes |
| Unusual or customer-supplied material | No reliable rate in the system |
| Failed or borderline DFM checks | The part may need changes before it can be made |
| Assemblies or multi-body files | Which bodies to make, and how, needs a decision |
| High order value | One mistake costs more than the time to check |
| Certificates, traceability, regulated sectors | Paperwork and inspection beyond the standard |
A common set-up is to show an instant price for parts that pass every check, show the price marked “subject to review” for borderline cases, and replace the price with a request-a-quote form for the rest. The RFQ process covers what happens to the requests that go to a person.
What makes an instant quote trustworthy?
- Your own numbers. A generic price list is a marketplace’s price, not yours.
- Real geometry. A volume multiplied by a rate misprices thin shells and dense blocks in opposite directions.
- Visible lines. If you cannot see why a price is what it is, you cannot fix it when it is wrong.
- Checked against reality. Compare instant prices with the actual cost of jobs you have run, and adjust.
- Change control. When you change a rate, you should know which past quotes it would have moved.
How to introduce instant quoting without giving away margin
Shops that start well tend to follow the same order.
- Start with one process you know well. The one where your hand estimates are already reliable, so you can tell when the software is wrong.
- Enter your real numbers. Machine speeds, material prices per kilogram, labour minutes per activity, set-up, minimums and margin. Defaults are a starting point, not your shop.
- Price parts you have already made. Take a few dozen recent jobs, price them in the new system and compare line by line with what you quoted and what the job really cost. Running a new configuration against past quotes like this is backtesting.
- Set the review triggers. Decide which tolerances, quantities, materials and order values go to a person, using the table above as a starting list.
- Publish, then watch. Read every instant order for the first weeks. Each surprise is either a rate to correct or a trigger to add.
The aim of the first month is not speed; it is confidence that the prices are yours. The simulator page shows one way to run step 3 before anything goes live.
Where instant quoting sits among other tools
Instant quoting is a kind of CPQ built around geometry rather than a product catalogue. It is not an ERP and does not replace job costing or scheduling; it usually hands orders to whatever system the shop already runs. If you are choosing software, choosing instant quoting software lists the questions to ask.
Quotometry is one such system: it analyses a part once and re-prices every option from that analysis, shows DFM checks to the buyer, and routes orders that need a person to an inbox with manual review, as described on the instant quote widget page. It prices 3D printing, CNC milling and turning, laser, waterjet and plasma cutting, injection moulding and vacuum casting today; the technologies overview lists each process.
Questions people ask
Is an instant quote a binding price?
That depends on the shop's terms, not the technology. Many shops treat an instant quote as a firm offer for parts that pass the automatic checks and as an estimate, subject to review, for everything else. Whichever you choose, say so on the quote and in your terms, and say which conditions turn an instant price into a reviewed one.
How accurate are instant quotes?
As accurate as the cost model behind them and the rates fed into it. A model that measures the geometry properly and uses the shop's real machine speeds, material prices and labour times can track a hand estimate closely. A model that multiplies volume by one number cannot. Compare instant prices with the real cost of jobs you have run, and adjust the model where they differ.
Does instant quoting replace the estimator?
No. It takes the repetitive quotes off the estimator's desk so that their time goes to the jobs that need judgement: tight tolerances, assemblies, large volumes, unusual materials and anything the automatic checks flag. In most shops that adopt it, the estimator becomes the person who maintains the rates and rules the system uses.
What file formats does instant quoting need?
A 3D model. Mesh formats such as STL, 3MF and OBJ are enough for 3D printing. Machining usually needs a solid model such as STEP, because features like holes, threads and faces are lost in a mesh. Drawings with tolerances and notes still matter, and a request that depends on a drawing note is a reason for review.
