Website Design & Development Services
A custom calculator gives your website visitors the number they came for, a saving, a price, a return or an instant quote, in exchange for their contact details. GLO designs and builds calculators and quote tools to your pricing logic, connects them to HubSpot, and rebuilt one client’s website around a lead form and savings calculator that more than doubled its conversion rate.
Buyers want a number before they want a conversation. A calculator or quote tool gives them one from their own inputs, and gives your sales team a lead that arrives with the size, the budget and the timescale already known. GLO has built a Cost Savings Calculator for Loft Insulation Installer, a cask investment calculator for Whiskey Investments and a two-step quote form for Noah Building Systems, mapped field by field to HubSpot.
Instant quotes, cost estimates and savings figures calculated from the buyer’s inputs, without a call.
The result is revealed behind a short form, so the lead is captured at the moment the buyer most wants the answer.
Every input the buyer enters, from square metres to budget, arrives in HubSpot as a property your team can filter on.
Your prices, tiers, discounts and rules, built once and applied consistently to every enquiry.
A homeowner comparing insulation wants to know what they will save. An investor wants to know what six casks cost with the discount applied. An operations manager wants a quote for a 20 m by 60 m building on their own site. Each is a different tool, and each captures a different, better-qualified lead than a contact form.
Calculators are the middle ground in the lead generation tools we build. They are quicker to build than a full 3D configurator and they qualify far more than a gated guide. Where the buyer’s price depends on a visual design, we will recommend a configurator instead, and where the numbers need a survey, the tool says so and books it.
Price the job from the buyer’s inputs and reveal the figure behind a short form, with the quote emailed as a PDF.
Show what the buyer stands to save or earn, like the Cost Savings Calculator on Loft Insulation Installer.
Indicative costs by size, specification and options, with the assumptions stated and the survey booked from the result.
Contact details first, project brief second, mapped field by field to HubSpot, as built for Noah Building Systems.
Volume tiers, discounts and deposits calculated live, like the cask calculator on Whiskey Investments.
Automatic quote PDFs, HubSpot contacts and deals, and the sequence that follows up.
Here is how we turn your pricing logic into a tool that generates priced, qualified leads.
We map how you price: the inputs that matter, the rates, tiers and rules, and the point where an estimate needs a survey. With your sales team we agree which details qualify a lead and where the tool asks for them.
The calculator is designed as a short, visible journey: a handful of inputs, a live result and a clear next step, with every assumption stated so the number is trusted.
We build the tool as a fast, mobile-first component of your website, with the logic tested against your own quotes before anyone sees it.
The result is revealed behind a short form placed at the point of highest intent, or shown live with the quote PDF gated, depending on what your buyers will tolerate.
Every submission creates a HubSpot contact and deal with the inputs and result mapped to properties, and emails the buyer their figure or PDF quote within seconds.
We launch with conversion tracking in place, watch completion and drop-off, and refine the inputs, the reveal point and the follow-up with your sales team’s feedback.

Book a free consultation and we will map your pricing logic, recommend the calculator or quote tool that answers your buyer’s question, and outline the reveal point, the PDF and the HubSpot set-up with a fixed price and timescale. No cost and no obligation.
A custom calculator is an interactive tool built into a website that takes a few inputs from the visitor and returns a figure calculated to the business’s own rules: a saving, a cost estimate, a return on investment or an instant quote. Unlike a generic calculator widget, it is built around your products, prices, tiers and assumptions.
For lead generation, the result is usually revealed behind a short contact form and sent to the visitor by email, and the inputs and result are recorded in HubSpot so the sales team can follow up with the buyer’s numbers in front of them.
The one that answers the question stopping your buyer from moving forward. For home improvement and energy products, a savings calculator works because the buyer is weighing a cost against a return. Made-to-measure buildings and installations suit an instant quote or cost calculator, because price is the first question.
Investments and subscriptions suit an ROI or deposit calculator, which does the same job. In every case the reveal should happen behind a short form, placed after the buyer has invested enough effort to want the answer.
Accurate enough to be trusted and clearly labelled as indicative. Most of our clients quote a range or a from-price based on the buyer’s inputs, state the assumptions on screen and confirm the final figure after a survey or technical review. A buyer who gets a realistic number quickly is far more likely to book that survey than one who is told to call for a price. Where your pricing is fixed, the tool can quote exactly, produce a PDF and take a deposit.
The tool says so, and books it. Noah Building Systems’ quote form offers a free technical site survey as an option, and every design from its configurator carries a technical review note. The buyer still receives an immediate indicative answer, the survey request arrives with the specification attached, and your surveyor turns up knowing the size, use and site. In HubSpot the survey request is a property your team can filter and act on.
Every submission is sent to HubSpot in real time. The contact is created or updated, each input and the result are mapped to custom properties, and a deal is created where it fits your pipeline. Your workflows then notify the right person, start a sequence and create tasks. We build and test the mapping as part of the project, using live submissions, and we can set up HubSpot if you are not yet using it.
A single-purpose calculator or two-step quote form with HubSpot integration is typically built in days once the pricing logic is agreed. Tools with more inputs, tiers and PDF output take a little longer. The Noah Building Systems two-step quote form, with a twelve-field project brief mapped to custom HubSpot properties, was built and tested within the website’s 38-day project. The main dependency is always the pricing logic from your side, so we start there.
Yes. The Whiskey Investments cask calculator lets an investor size an order, see six volume-discount tiers apply as the quantity changes and reserve with a 10 percent deposit. Where a tool takes a deposit, the payment is handled by a payment provider and the reservation is recorded with the lead. For most quote tools a deposit is not appropriate, and the tool ends with a PDF quote and a booked call or survey instead.
