Sales catalog app for reps: always up to date, and it works with no signal
A sales catalog app gives your reps products, photos, prices and stock that are always current, updated from one dashboard. It works with no signal and lets them take the order on the spot, replacing the PDF that's out of date a week later.

A sales catalog app puts your products, photos, prices and stock on every rep's or reseller's phone, and you update all of it from one dashboard. It works with no signal and lets them take the order right there, in front of the customer.
It fits distributors with reps on the road, manufacturers with sales agents in other regions, and brands that sell through independent resellers. Here's what it fixes, what it should include, and what to figure out before you have one built.
The trouble with the PDF catalog
Almost everyone starts the same way: a PDF with photos and prices that gets passed around by email or WhatsApp. It works until something changes. A price goes up, a product sells out, something new comes in, and the PDF is already stale. You make a new one, send it again, and there's always someone who shows a customer the version from two months ago.
What you get is orders at prices you no longer honor, requests for things you don't have, and an awkward call explaining that what the customer saw isn't what's available. The more reps or resellers you have, the more versions of the catalog are floating around.
With an app, there's one catalog. Change something in the dashboard and it changes for everyone.
What should it include?
You don't need all of this on day one, but these are the parts that get used the most:
- Search and categories: reps find a product in seconds by name, SKU or category, even if you carry hundreds.
- Photos and product details: sizes, colors, pack options and whatever customers usually ask about.
- Price lists: wholesale, retail or reseller, and each rep only sees theirs.
- Visible stock: so nobody promises what isn't there, or so they can say it's arriving next week.
- Orders on the spot: the rep builds the order with the customer and it reaches you fully itemized.
- Share by WhatsApp or text: send a customer one product or a selection with photos and price, no screenshots.
- Works with no signal: more on that below, because it's the biggest difference between an app and a website.
No signal, still selling
The rep driving rural routes, the agent visiting a plant in an industrial park, the reseller showing products in a customer's living room: signal drops right when you need it. A catalog that depends on the internet just spins, and the sale cools off.
That's why the catalog should live on the phone. The rep shows everything, builds the order and leaves it ready; when the connection comes back, the order goes out and the catalog picks up the latest changes. The same goes for trade shows, which I covered in selling at trade shows without internet. For made-to-order products, the Estructuras 3D blog has a piece on an offline 3D quoting tool.
Your own reps vs resellers
With your own sales reps, the app usually goes hand in hand with managing them: which accounts they visit, what each customer ordered, and how much each rep sold. If that's you, also look at the field sales app, which focuses on visits and routes.
With resellers, the priorities change. The catalog has to look good enough to show their own customers, sharing products has to be easy, and they shouldn't see your costs or anyone else's prices. Often the reseller only needs their price and the suggested retail price, nothing more.
And if your wholesale customers want to order on their own, without going through a rep, that's a wholesale ordering portal, and it can share the same catalog.
Prices that stay current without calling anyone
I've already solved the “always up to date” part in another industry. For Boca de Lobo, a steakhouse with two locations in Buenos Aires, I built a website with a QR menu of more than 250 items and its own dashboard, so the team changes prices, dishes and specials without waiting on a developer. A sales catalog app runs on the same idea: one place where everything gets entered, and one version everybody sees.

Three questions that shape the whole project. How many price lists do you have, and who changes them? Should orders reach you by WhatsApp, by email, or inside your business software? Do reps need live stock, or is a general idea of what's available enough?
That's enough to build a first version. I work on my own, remotely from Buenos Aires, Argentina (UTC−3), with video calls, progress you test on your own phone from a link, and contact by WhatsApp or email. I quote each project based on what it needs; you can see what else I do on services.
Frequently asked questions
Does it really work with no signal?
Yes. The catalog, photos and prices are stored on the rep's phone. They can show products and take orders in a store with no signal or out on the road, and orders go out on their own once the phone reconnects.
Can each rep see different prices?
Yes. You set up lists by customer type or by rep: wholesale, retail, reseller, or whatever you use. Each person only sees the one that applies to them.
Does it have to be on Google Play or the App Store?
Not necessarily. It can be an app installed from a link that sits on the home screen like any other, without going through the stores. If you'd rather have it in the stores, that works too.
Who updates products and prices?
You or someone on your team, from a dashboard. Change a price once and every rep sees it the next time their phone connects.
