The short answer
Quoting software falls into three kinds, and they solve different problems. Configure, price, quote software handles products built from options and rules. Instant quoting tools price a custom part from its drawing or model. And an agent that reads enquiries prices a list of items against your catalogue. Look at what arrives in your quoting inbox and the right kind is usually obvious.
If customers ask for a configured machine, you need the first. If they send part files, the second. If they send a bill of quantities, a schedule or a long email of items, you need the third.
I build the third kind, so that is my bias, and the client result is further down the page. Vendor facts were checked on the vendors' own pages on 12 October 2026.
1. Configure, price, quote software
This is the oldest kind. The product is a set of options with rules about which combinations are valid and what each adds to the price. A salesperson or the customer walks through the choices and the software produces a valid configuration and a price.
Tacton is a well-known example and describes its product as built for manufacturers of highly configurable products, with guided selling and rule-based configuration. It publishes no price, so expect a sales process. This kind of software pays off when the same product family is quoted again and again with different options. It is the wrong tool for pricing a list of catalogue items.
2. Instant quoting from part files
Job shops and contract manufacturers quote parts that have never been made before. Here the software reads the geometry of an uploaded part file and estimates material, machine time and cost from the shop's own rates.
Paperless Parts lists sheet metal fabrication, CNC machining, Swiss screw machining, additive and rubber manufacturing among the kinds of shop it is built for. DigiFabster quotes 3D printing, CNC and sheet metal work and sells in tiers it calls Essential, Growth and Enterprise. Both start from a part file, which is a different job from reading a bill of quantities and looking items up in a catalogue.
3. An agent that reads enquiries against your catalogue
Many manufacturers and distributors quote from a catalogue. The enquiry is an email with a multi-sheet bill of quantities or a schedule covering several brands, and the estimator's day goes on reading each line, finding the matching item and applying the right price and discount.
An agent can do the reading and the matching. It reads the enquiry and every sheet whatever the layout, matches each line to an item in the live catalogue, and hands the matched lines to a pricing step. A person reviews the draft and sends it.
The design choice that matters is to keep the arithmetic away from the model. A model is good at reading messy input. A rules engine is good at producing the same price every time. Put the prices and discount rules in the rules engine, so that every figure on the quote traces to a catalogue entry and a rule.
Why pricing must be rules, not a model
A quote that is nearly right is worse than a late one. A wrong price is either a loss you have to honour or an awkward call to withdraw it, and customers remember both. So the bar for the pricing step is not high accuracy. It is the same answer every time, with a reason.
Keep the model's job to reading and matching, where a person can check its work at a glance, and keep pricing in deterministic rules behind tests. In the system described below the pricing logic sits behind a suite of 87 tests, so a change to a rule or a model cannot quietly change a price.
Price against the live catalogue, not an export. A copy drifts out of date, and a quote built on last month's prices is wrong in a way nobody notices until the order arrives.
What to prepare before you automate
Collect a few months of past enquiries with the quotes that were sent. They are your test set. A new system should reproduce the quotes your best estimator produced, and every difference is either a fault or a rule nobody had written down.
Write the pricing and discount rules down. Most quoting teams hold them in one or two heads. Getting them onto paper is the slowest part of the project and the most valuable, because it is the first time the business sees its own pricing logic in one place.
Decide what the agent must never do alone. Sending the quote, pricing an item it could not match and applying a discount outside the rules are the usual three.
The three kinds compared
| Kind | What arrives | What it automates | Wrong choice when |
|---|---|---|---|
| Configure, price, quote | A request for a product with options | Valid configurations and their price | You quote lists of catalogue items |
| Instant quoting from part files | A drawing or 3D model | The cost of making a new part | You sell from a catalogue |
| Agent reading enquiries | Emails, bills of quantities, schedules | Reading, item matching and a priced draft | Every quote is a new engineered design |
How to choose
Open the last fifty enquiries and sort them by what the customer sent. That count tells you which kind you need better than any demo.
If most are requests for a configured product, look at configure, price, quote software. If most are part files, look at the instant quoting tools built for your processes. If most are lists of items to be priced from your catalogue, the bottleneck is reading and lookups, and that is the case an agent with a rules engine handles.
Whichever you choose, measure quote turnaround before and after, from the enquiry arriving to the quote leaving. It is the number your customers feel.
