Offline 3D Quoting Tool: Quoting at Trade Fairs, Job Sites and Farms
By Facundo Campo, 3D quoting tool developer
In short: An offline 3D quoting tool is an installable app that lets you configure the product, see it in 3D and save quotes on the device even with no signal, then syncs them with the central system when the connection returns, without duplicating contacts.
Saturday at noon, an agricultural show, the booth of a horse barn manufacturer. A rancher is interested in six stalls with a tack room, the sales rep has the iPad in hand, and the phone signal shows one bar that comes and goes. If the quoting tool depends on the internet, the sale turns into "I'll send it to you on Monday." If it works offline, the rancher leaves having seen his barn in 3D, and the quote is saved for follow-up.
That's an offline 3D quoting tool: an app installed on the tablet or phone that lets you configure, view in 3D and quote with no signal, and that syncs everything when the connection comes back.
Where sales happen with no signal
For many construction manufacturers, sales don't happen in an office with Wi-Fi. They happen in places like these:
- Agricultural shows and regional trade fairs. Thousands of people on the grounds, all with their phones, and a network that can't keep up. I wrote about selling there in selling at agricultural shows and trade fairs.
- Out in the countryside. A steel fabricator's sales rep goes to see where the building will go, 40 km (about 25 miles) off the highway, and wants to show the farmer how the 18 × 30 m (about 59 × 98 ft) one looks with the sliding door facing the road.
- The job site. A lot in a new development with no utilities, where the customer wants to see the prefab home while standing on the land.
- On the road. The sales rep who visits three towns in one day and quotes between stops.
In all those cases, the alternative without an offline quoting tool is the usual one: jot it down on paper, snap a photo of the sketch, promise the quote for later. And "later" is exactly when the customer cools off or asks someone else for a price.
What has to work offline
It's not enough for the page to "load" without internet. To be useful at a booth, everything the sales rep uses in the conversation has to work:
- The full 3D. The engine, the parts, the textures and the options have to be stored on the device. If the model downloads something when an option changes, it breaks without signal.
- The price calculation. The current price table has to be on the device, updated the last time there was a connection.
- Customer details. Name, phone, town, what they configured and what they were quoted.
- The quote. It should be possible to generate it on the spot, or at least have it ready to send as soon as there's signal.
And then there's the part that's most noticeable when it fails: syncing. When the signal comes back, the saved quotes upload to the central system, show up in the CRM, and the rest of the team can see them. Without duplicating contacts, because at a fair it's normal for the same rancher to stop by the booth twice or to be helped by two different sales reps.
How I solved it for EQUIBOX
EQUIBOX is a manufacturer of horse stalls and modular stables in Berazategui, Buenos Aires, that uses its quoting tool at agricultural shows. When I built its quoting system, offline use was a requirement from the start, not an add-on.
The quoting tool is an installable app: it installs from the browser, with no app store involved, and stores what it needs on the device. Quotes are saved on the tablet while there's no signal and synced when the connection returns, without duplicating contacts. The 3D runs smoothly on an iPad, which is what's used at the booth.
Another decision came out of the same context: the quoting tool's night mode is deliberately exaggerated. At a booth in the sun, a screen with soft colors can't be seen. These are details that don't appear in any spec sheet and that you only discover by thinking about where the tool will be used. I go into more detail in EQUIBOX design decisions.
What the manufacturer gains
The most direct benefit is that the sale doesn't get cut off. But there are others, less obvious:
- No contact gets lost. Not every scrap of paper from the booth makes it back to the office. A quote saved on the device does.
- The price is current. No printed price list from two months ago: the calculation uses the table from the last time there was a connection.
- The sales rep doesn't depend on the owner. They can quote out in the field with the same rules used at the factory. More on this in sales reps who quote on their own.
- Follow-up starts the same day. When the sales rep gets signal again on the road, the quotes are already in the CRM with their next follow-up.
What to keep in mind
Offline mode has a development cost and a few usage rules. It's a good idea to open the app with signal before heading out, so it downloads the latest price table. And if a sales rep goes many days without a connection while prices change, the system should warn them that they may be quoting with outdated values.
Not every manufacturer needs it, either. If you sell from a showroom in the city of Córdoba and over WhatsApp, a quoting tool that works well on a phone is enough. If you sell at fairs, out in the countryside or on the road, it's probably one of the first things worth asking for. It's one of the factors I explain in how much a 3D quoting tool costs.
Facundo Campo builds these quoting tools end to end, and EQUIBOX's offline mode is in production. If your team sells where there's no signal, tell me what a day at a fair or on a site visit looks like and we'll see what's needed: WhatsApp +54 9 11 6193-3176 or facundocampo100@gmail.com. You can also look at custom 3D quoting software development or try the horse stall configurator, which uses the geometry from the EQUIBOX quoting tool.
Frequently asked questions
Can a 3D quoting tool work without internet?
Yes, if it's built as an installable app. The 3D engine, the options and the price table are stored on the device, and quotes are saved locally until the signal returns.
Does it have to be downloaded from an app store?
No. It's installed from the browser, on a phone, tablet or computer, and gets its own icon like any other app.
What happens if the same customer is quoted twice with no signal?
The sync has to recognize it and not duplicate the contact. At EQUIBOX this is part of the design, because at a show it's common for a rancher to come back to the booth.
Do the public configurators on this site work offline?
The public Estructuras 3D configurators are for trying the engine online. Offline mode is part of the custom development for each manufacturer.
