What is an online configurator?
An interactive part of a website where customers choose from options such as type, size, material, colour and extras, and immediately see how their choices play out. At the end they send a finished brief.
A configurator replaces long back-and-forth emails. Instead of the question "do you make gates too?", you receive an enquiry with the exact gate type, dimensions, colour, opening mechanism and location. The business can respond straight away and specifically. If you are looking for someone to build one for you, have a look at my services.
A good configurator feels like a conversation with an experienced salesperson. It asks only about what matters, in a logical order, and does not let the customer pick an option that makes no technical sense. I built a configurator like this for my own website. In it, the customer goes through 12 steps, from whether they already have a website to the features they need. Every step is saved as they go, and I receive a clear brief from which I can prepare a design right away.
What is a website calculator and how does it differ from a configurator?
A calculator calculates: it works out a result from the data you enter. A configurator assembles: it guides you through a choice of options. They are often combined in one tool.
Typical website calculators
- working out the amount of material from dimensions (tiles, paint, insulation),
- estimating a delivery date based on the scope of the job,
- calculating consumption, savings or payback,
- comparing variants based on the customer's parameters.
For M2M Solutions I built an ROI calculator for their transport logistics system. The visitor enters their figures, the calculator works out the annual savings and return on investment, and the result is sent to them by email. The company receives the contact together with the calculated data.
Typical configurators
- custom furniture, kitchens and wardrobes,
- windows, doors, gates and fences,
- service packages, for example the scope of a website, cleaning or maintenance,
- gifts and personalised products.
Configurator, calculator or contact form: which to choose?
A contact form is enough for simple services, a calculator suits customers who want to know the result of a calculation, and a configurator fits when a product is made up of several dependent choices.
Not every website needs a configurator. The table shows when a simpler tool is enough and when a more complex one pays off.
| Tool | When it is enough | What the business receives | Effort |
|---|---|---|---|
| Contact form | the service is simple, details are settled in conversation | free text and contact details | lowest |
| Multi-step form | you ask for the same details with every enquiry | structured data in the same order | low |
| Calculator | the customer wants to know a quantity, estimate or payback | the input data and the calculated result | medium, depending on the calculations |
| Configurator | the product has many dependent variants | a precise brief with validated combinations | higher, depending on the number of rules |
You can also go step by step. A business can start with a multi-step form and, once it is clear which choices customers deal with most, extend it into a configurator.
Which businesses does a configurator or calculator pay off for?
For businesses whose product or service has several variants and where many details have to be clarified with each enquiry: custom manufacturing, construction, packaged services, logistics or technical products.
The clearest signs that a configurator will pay off for you:
- you reply to every enquiry with several follow-up questions,
- customers often do not know exactly what they need and have to be guided,
- your offer has many combinations that are hard to describe in text,
- you want customers to see the result of their choices before they get in touch.
Examples from different industries
- Joinery: choosing the wardrobe type, dimensions, material and handles with a preview.
- Construction company: a calculator for the area and material of a facade or roof.
- Logistics: a savings and return on investment calculator, like the one I built for M2M Solutions.
- Servicing: choosing services for a package and proposing a date.
- Web design: choosing the sections and features of a future website, as in my own configurator.
Want a configurator or calculator on your website?
I build configurators and calculators as small custom web applications. Take a look at what I do.
ServicesWhat are the benefits for the business and the customer?
The customer finds their way faster and feels more confident. The business receives complete, structured enquiries, saves time on follow-up questions and better understands what customers want.
For the customer
- sees the options and the result of their choices straight away,
- does not have to wait for an email reply,
- can try out combinations at their own pace, even in the evening.
For the business
- a complete brief in the very first message,
- fewer misunderstandings and repeated questions,
- an overview of which variants are most in demand,
- the enquiry can be logged automatically in a CRM or spreadsheet, more in the article on AI automation for small businesses.
How is a custom configurator built?
It starts by writing down the rules: what the choices are, how they depend on each other and what should come out at the end. Then come screen design, development, integration with the website and testing.
- Rules and variants: we list all choices, constraints and calculations.
- Step design: the order in which the customer decides, so that it feels natural.
- Visual design: a look that matches your website, with an emphasis on mobile.
- Development: logic, calculations, previews and sending the enquiry.
- Integration: email, CRM, spreadsheet or internal system.
- Testing: with real briefs, so that the results match practice.
A configurator is really a small custom web application, so the same principles apply: start with what matters most and extend step by step.
What should a good online configurator have?
Clear steps, understandable choices with images, instant feedback, a summary at the end, comfortable use on mobile and the option to save a selection in progress.
- Sequence: one step, one decision, visible progress.
- Visuals: images or icons next to choices, not just text.
- Instant feedback: the result changes as soon as a choice changes.
- Mobile: large buttons and readable text on a small screen.
- Summary: an overview of all choices before sending.
- Saving: the customer can come back to their selection later.
- Accessibility: keyboard control and sufficient contrast.
The same quality principles apply to the whole website, and I write about them in the article on recognising a quality business website.
How does a configurator improve the quality of enquiries?
A configurator ensures that every enquiry contains all the necessary details in the same structure. The business can then respond faster and more accurately.
Without a configurator, enquiries arrive in all shapes: sometimes a short sentence, other times a long email without the essential details. Each one has to be read, followed up with questions and copied into your own overview. With dozens of enquiries a month, that adds up to many hours of work that brings nothing new.
A configurator removes this chaos. Every enquiry has the same fields, the same order and the same units. It can be compared straight away, sorted by priority and assigned to the right colleague. At the same time, the customer sees that the business has thought its processes through, which strengthens trust.
What a configurator usually collects
- the chosen product or service and its parameters,
- dimensions, quantities or scope,
- the requested date and location,
- contact details and consent to processing,
- an optional note or photo from the customer.
Which mistakes should a configurator avoid?
Too many steps at once, unclear option names, no mobile version, a result without explanation and a configurator that saves nothing when it is not completed.
A configurator should help the customer, not test them. Most problems arise when the business's internal view is carried over instead of the customer's view.
- Technical names: customers may not know technical designations. An image or a short description next to each choice helps.
- A long first screen: if they see dozens of fields right at the start, they leave. Each step should have one decision.
- Impossible combinations: a configurator should not allow a choice that cannot be made or delivered.
- A result without context: if a calculator shows a number, it should explain what it is based on and whether it is a rough estimate.
- Losing a brief in progress: saving as they go helps both the customer and you if the enquiry is not completed.
- Forgetting mobile: many people open a configurator on their phone, so it should be designed for the small screen first.
Most of these mistakes are revealed by a simple test: ask someone who does not know your business to fill in the configurator and watch where they hesitate.
How do you start if you are considering a configurator?
Write down the questions you ask with every enquiry and the variants you offer. That becomes the skeleton of the configurator.
The simplest start is to look at your last twenty enquiries. What information did you have to find out from customers? In what order? Where did misunderstandings arise most often? These answers are exactly the steps the configurator should contain.
There is no need to start with all variants at once. The first version can cover the most popular products or services, and more can be added once you see how customers use it. If you also need appointments and bookings, read the article on a custom booking system.
Frequently asked questions
What is an online configurator?
A tool on a website in which the customer chooses the parameters of a product or service step by step, sees the result of their choices and at the end sends a finished, structured brief.
What is the difference between a calculator and a configurator?
A calculator works out a result from the values you enter, for example the amount of material. A configurator guides you through a choice of options. In practice they are often combined in one tool.
Can a configurator be added to an existing website?
Yes. A configurator can be placed on a separate subpage or in a section of an existing website and styled to match it.
How much does a custom configurator cost?
It depends on the number of steps and variants, the complexity of the calculations, previews and where enquiries should be sent. A first version with a few steps and sending to email is usually a matter of days, not months.
Does a configurator work on mobile?
Yes, if it is designed that way. I focus on large buttons, readable text and simple steps so that it is comfortable to use on a phone too.
