An app to sell at rural expos with no internet: how it works

An app for selling at rural expos has to work without internet: the sales rep builds the quote at the stand, the contact is saved on the device and syncs automatically when the signal comes back. It can be built as an installable web app, without going through the app stores.

Here is what it needs to solve, what the options are and how I solved it in the EQUIBOX configurator. EQUIBOX is a horse stable manufacturer in Argentina that makes a good share of its sales at rural expos, the big agricultural and livestock shows held in the countryside.

Why does a regular website fail at a stand?

Because it depends on the signal for every click. At a rural showground the connection comes and goes, and when there are lots of people it gets saturated. The result is familiar: the page keeps loading with the customer in front of you, the form gets lost on submit, and the sales rep ends up writing on paper and typing everything in at night, if they remember.

At an expo, customers also arrive in waves over a few hours. Every lost contact is a sale nobody follows up. So for anyone who sells at fairs, a tool that works without signal is not a technical luxury: it is the difference between being able to use it or not.

What is an installable web app?

It is a web page that can be installed on a phone, tablet or computer and sits on the home screen like an app. What matters here is that it can store the entire application on the device, so it opens and works even with no connection.

It does not need to be published on Google Play or the App Store, and it updates itself when there is signal. If you want the general comparison, I covered it in mobile app or website?; the technical side of how data syncs is in offline-first architecture.

What else matters when it is used at a stand?

Besides working without signal, at EQUIBOX some decisions were made for the place where it is used:

• The 3D has to run smoothly on an iPad. It is tuned so the stable moves without stuttering on a tablet, even in night mode.
• It has to be visible in the sun. Night mode is exaggerated on purpose: at a stand in full sunlight, a subtle effect cannot be seen.
• It has to load fast on a weak signal. The screen is kept light so there is little to download.
• The camera has to frame itself. It reframes based on the size of the stable, so the sales rep does not have to zoom with the customer waiting.
• It must not limit what can be sold. There is a visual limit of stalls per group so the 3D does not slow down, but it does not limit what can be quoted.

Regular website, installable web app or app store app?

I break down the store accounts in how much it costs to publish an app.

What should you test before the expo?

• Install it on the stand devices with signal, the day before, so everything is downloaded.
• Quote in airplane mode. Build a full quote offline and check that it is saved.
• Reconnect and check that it reaches the system exactly once.
• Look at it in the sun. What looks fine in the office may be unreadable outdoors.
• Charge the battery and bring a spare. No app works with the tablet switched off.

How much does it cost?

A sales app that works offline is a custom web system, so what defines the cost is what it has to quote, how many products and options it handles, and where each lead has to go (WhatsApp, CRM, email). The offline part adds work, and it is much cheaper if it is planned from the start than if it is added to a finished app. If you also want to quote with prices, shipping and payment plans from the same stand, I covered it in sales system and CRM for manufacturers.
