Wholesale ordering portal: let your trade customers order on their own, with their prices and history
A wholesale ordering portal is a private website where each customer logs in, sees products at their own prices, repeats past orders and sends them to you ready to pick. It replaces voice notes, photos of handwritten lists and late-night WhatsApp orders.

A wholesale ordering portal is a private website where your trade customers (grocers, convenience stores, restaurants, hardware stores, resellers) log in, see your products at their prices and send you a complete order. No endless voice notes, no photo of a list written in pen, no “same as last time, please.”
I'm going to look at it from your customer's side, because they're the ones who have to want to use it. If ordering through the portal isn't easier for them than sending you a text, they won't use it, no matter how nice it looks.
How your customers order today, and why it costs you so much time
The store owner orders whenever they can: at night, after closing, looking at the empty shelves. They send you whatever they remember, sometimes with names only they understand (“the one with the green lid”). The next morning someone on your team decodes it, types it into a spreadsheet, checks stock and replies. If something's missing, another round of messages starts.
That back-and-forth is invisible, but it eats office hours every week. And every time a voice note gets turned into a spreadsheet row, there's room for a mistake: cases instead of units, the wrong pack size, last month's price.
What your customer sees when they log in
The whole point is that ordering has to be faster than typing a message. These are the things that make the difference:
- Their last order, ready to repeat: one button to load last week's order and change only what's different.
- Their prices, not the list price: each customer sees their own price list, discounts and payment terms.
- Clear photos and pack sizes: each product with a photo, the unit you sell it in (case, pack, bundle) and its code. No more “the green lid one.”
- What's in stock and what isn't: if something's out, they see it before ordering, not the next day.
- Order status: received, being picked, out for delivery. One less “where's my order?” text.
- History and balance: what they bought, when, and what they owe, without asking anyone for a statement.
What changes for your team
| Moment | Orders over WhatsApp | With the portal |
|---|---|---|
| A customer orders at night | The message waits until morning | The order arrives clean, ready to pick |
| It has to go into your system | Someone retypes it | It's already in, with codes and quantities |
| A product is out of stock | You tell them and haggle over chat | They saw it was out and picked something else |
| Prices change | You send everyone a new PDF | Each customer sees current prices when they log in |
| “Where's my order?” | Someone looks it up and replies | They check it themselves |
“What about my sales reps? Does this replace them?”
It's the question I hear most, and the answer is no. The portal takes the routine restock order off their plate, the one that repeats every week and doesn't need a conversation. Reps are then free for the work that does need a person: opening new accounts, introducing products, negotiating a big order or handling a complaint.
Reps can also use the same portal to enter orders on a customer's behalf during a visit. That way every order ends up in the same place, wherever it came from. If what you need is warehouse and delivery control, I covered that in inventory system for distributors.
A real example: the customer builds the order, and it arrives complete
For EQUIBOX, a horse stall and stable manufacturer near Buenos Aires, I built a 3D quoting tool where the customer designs their stable (size, model, walls, accessories), downloads a PDF spec sheet and requests the quote on WhatsApp. The company gets the inquiry fully defined and follows up with its CRM and sales team. It isn't a wholesale portal, but the principle is the same: the customer puts together what they want on their own, and you receive it complete. If you manufacture and sell through dealers, I wrote about a 3D configurator for dealer networks on the Estructuras 3D blog.

If you want any business to find you on Google and buy by card, what you're after is a wholesale online store. If your customers are already yours, order every week and each one has their own price, you need the portal. Some businesses have both: the store to bring in new accounts and the portal for the regulars.
To get started, the catalog, customers with their price lists and the order itself are enough. Order status, balances and history can come later. I work on my own, remotely from Buenos Aires, Argentina (UTC−3), with progress you can open from a link, and I quote each project separately. If you want to see how I split a project into stages, I wrote about building software in phases.
Frequently asked questions
How is this different from a wholesale online store?
An online store is usually open to anyone and sells through a cart and checkout. The portal is private: only your customers get in, each one sees their own prices and terms, and orders go into your process without an online payment step. Many businesses combine the two.
Do my customers need to download an app?
No. They open it in their phone or computer browser with a link and their login. If they like, they can save it to their home screen and it sits there like any other icon.
What if a customer keeps ordering over WhatsApp anyway?
It happens, especially at first. You or your rep can enter that order in the portal on their behalf, so everything still ends up in one place. Over time, customers who see it's faster start using it on their own.
Can I set a minimum order or delivery days by area?
Yes. Your business rules go in: minimum order, delivery days by area, products only certain customers can see, and a cutoff time to make the next day's delivery.
If your wholesale customers order through voice notes, photos and scattered messages, message me on WhatsApp at +54 9 11 6193-3176 or email contacto@facundocampo.com.ar. I answer in English and Spanish. Tell me what you sell, who to, and how orders reach you today, and I'll tell you how I'd set up your portal.
