Mobile 3D Quoting Tool: Why It Has to Work on a Phone

In short: A 3D quoting tool has to work on a phone because that's where a custom manufacturer's buyer makes the inquiry, receives the link over WhatsApp and shares the configuration with family or a partner; making that work requires a lightweight 3D engine that runs in the browser with nothing to install.

It's eleven at night, and a sales rep for a prefab home manufacturer in Moreno, on the outskirts of Buenos Aires, is answering WhatsApp from bed. A couple asks about "the two-bedroom one with the porch." He sends them a link; they open it on their phone, remove the pool, switch the cladding to stone, rotate it, and forward it to the mother-in-law. The next morning the inquiry comes back with the exact configuration. None of that happens if the 3D quoting tool only works on a computer.

That's why a 3D quoting tool has to work on a phone: because a custom manufacturer's inquiries come in, get discussed and get decided on a phone.

Where your customer is looking

Think about how an inquiry reaches your factory today. An Instagram ad, a WhatsApp message, a friend passing along your number. In every case, the first contact happens on a six-inch screen.

And it's not just the buyer. The farmer who wants a metal building is out in the field, not at a desk. The owner of a horse breeding farm looks at stable photos on their phone between other tasks. The couple buying their first prefab home talks it over at night, each on their own phone.

If the quoting tool says "open this on a computer," you've lost half of those conversations before they start.

What changes when the 3D works on a phone

The inquiry arrives already built

Instead of "send me a price," the inquiry arrives with dimensions, options and an image. The sales rep knows what the customer wants before calling, and can prioritize someone who already built an enclosed 18 × 30 m (about 59 × 98 ft) building with a sliding door over someone who asked out of curiosity. There's more on that in inquiries that arrive with the configuration built.

The decision gets shared

Construction purchases are almost never decided by one person. There's the business partner, the spouse, the accountant, the engineer. A link that opens exactly the same configuration —which is what the Estructuras 3D configurators do— gets forwarded on WhatsApp and everyone sees it on their own phone, exactly as it is. Nothing needs describing.

The sales rep quotes on the go

The phone isn't just for the customer. A sales rep visiting a job site or a farm can open the quoting tool on their phone, change two dimensions in front of the customer and show them the result. I wrote about that use in the 3D quoting tool as a sales rep's tool.

What it takes to run well on a phone

A 3D quoting tool that "opens" on a phone is not the same as one that runs well. Some technical decisions make a big difference:

• Run in the browser, with nothing to install. A link, and that's it. Nobody is going to download an app to get a quote on a shed. The Estructuras 3D engine runs in current mobile browsers.
• Lightweight geometry. Since parts are generated from rules rather than downloaded as heavy models, the product appears quickly even on a weak connection. I explain it in parametric rendering.
• Careful lighting. Every light in a 3D scene makes the phone work harder. In the metal building configurator, for example, all the light tubes are drawn, but only a few actually cast light, so stretching the building to 90 m (about 295 ft) doesn't make the phone freeze.
• A touch-friendly interface. Large controls, options grouped the way the trade thinks about them (dimensions, structure, roof, cladding, openings, floor), and the 3D always visible while choosing.
• Quick views. Iso, front, side and plan with one tap. On a phone, rotating a model with your finger is fun but imprecise; a plan view settles the question in a second.
• Layers. Hide the roof or the cladding to see the structure, without having to understand how a 3D camera moves.

Phone, tablet and computer aren't the same

A well-built quoting tool works on all three, but each has its role. The phone is for the inquiry and for sharing. The tablet is for the booth and the meeting, where the customer looks at the screen alongside the sales rep; at EQUIBOX, the 3D runs smoothly on an iPad because that's what's used at agricultural shows. The computer is for the office: the sales panel, the CRM, the reports.

Designing mobile-first doesn't mean forgetting the rest. It means the part the customer sees has to work in the worst reasonable conditions: a mid-range phone, on mobile data, at night, one-handed.

And when there's no signal

The phone solves the where, but not always the connection. If you sell at trade fairs or out in the countryside, the next step is a quoting tool that can be installed and works with no signal. I cover it in quoting with no signal.

Try it yourself

The best test is to take out your phone right now and open the prefab home configurator or the metal building and shed one. Change dimensions, hide layers, switch to night mode and share the link with someone. That's how your customer will experience it.

Frequently asked questions

Does a 3D quoting tool work on any phone?

It works on current mobile browsers, which today is the vast majority. What varies from device to device is smoothness, which is why the engine is designed so a mid-range phone handles it well.

Does the customer have to download an app?

No. It opens from a link on WhatsApp, Instagram or the website. If the manufacturer needs it for trade fairs or the countryside, it can also be made installable.

Can a configuration be shared over WhatsApp?

Yes. The Estructuras 3D configurators generate a link that opens exactly that configuration, with the same dimensions and options.

Should the desktop version be built first and the mobile version later?

The other way around. The public side is best designed with the phone in mind, because that's where inquiries come in, and then the larger screen is put to use for the sales panel.
