Sellium for Construction MaterialsSellium for Construction Materials:job site orders on WhatsApp 24/7
The building-supply dealer does not want another portal: it wants to send a WhatsApp message and have the order go through. Sellium takes B2B orders around the clock for cement, rebar, concrete and ceramics, with channel pricing, the trade account checked against your ERP and the quality certificate attached, without adding people to the order desk.
How do you automate building-supply dealer orders on WhatsApp?
You automate building-supply dealer orders by connecting an AI sales agent on WhatsApp to the company's ERP and CRM. The agent identifies the customer by tax ID (CUIT), business name or delivery zone, understands the order in natural language ("600 bags of cement and 2 tons of 8mm rebar for Thursday"), quotes with the channel price list (dealer, contractor, installer), checks stock and the trade account, and loads the order into the system with its paperwork. The dealer owner never logs into a portal or learns anything new: they write the way they write to a trusted supplier.
In Construction Materials this matters more than in almost any other vertical: the dealer owner opens WhatsApp many times a day and email once, and the foreman orders on Saturday at 6 p.m. for Monday at 7 a.m., when nobody is behind the counter. Sellium, the sales agent in the Vantegrate Suite, was built for that counter: it answers every day at any hour and logs every order, from the first message to the delivery slip.
The full picture of the sector (the five agents applied to cement plants, ready-mix concrete producers, steel mills, distributors and dealer networks) is on the Construction Materials page.
The pain points of the materials counter
We mapped them in dozens of conversations with manufacturers, distributors and dealer networks across the sector's eight sub-verticals.
The dealer hates the B2B portal
The dealer owner lives on WhatsApp and hates logging into the portal. Orders go back to the phone, swamp the order desk, and an order that should go through in minutes ends up taking hours.
The foreman orders on Saturday at 6 p.m.
When cement runs short for Monday at 7 a.m., the request arrives after hours and nobody answers. The sale waits or goes to the supplier that does answer.
Differentiated pricing full of errors
Every quote combines customer, job site, zone and channel. Put together by hand, it produces errors that turn into days of disputes and re-invoicing with the customer.
Technical advisors answering the basics
Specialists answer simple questions from installers (which rebar meets the standard, which concrete applies) instead of closing large supply deals.
How Sellium handles it in the sector
The agent's capabilities, mapped to the vertical's pain points: each one works on your systems and your business rules, not on canned answers.
No portal
Natural-language orders, 24/7
The dealer writes the way they talk and the agent understands the full order: product, quantity, date and job site. It answers at any hour, every day, with no option menu or login.
Frictionless ID
Recognizes the customer by tax ID, account or zone
The dealer owner does not remember their customer number, but does know their delivery zone. Sellium identifies them against Salesforce and your ERP and pulls up their price list, history and commercial terms.
Channel pricing
Quotes with the current price list and volume
Applies channel pricing (dealer, contractor, installer, retail), volume discounts and per-job-site terms, and confirms against the sector's ERPs such as SAP S/4HANA Building Materials, JD Edwards or Dynamics 365.
Trade account
Checks balance, limit and financing
Answers trade account questions in natural language (balance, due dates, limit per job site) and, if the order goes over the limit, offers bank financing (BaaS) with an installment plan in the same chat.
Technical questions
Answers with the spec sheet and certificate
Resolves the technical question with the loaded catalog: which rebar meets IRAM-IAS U500 528, which concrete is H-21 and which porcelain tile is PEI 5, with the spec sheet and SDS attached on the spot.
Ready-mix concrete
Coordinates deliveries that cannot fail
For concrete, it takes quantity, grade, exact day and time and unloading method, checks the nearest plant and the product's shelf life, and schedules delivery within the municipal time window.
A Saturday night at the building-supply yard
The full flow with the sector's most awkward order: the one that comes in when nobody is there to take it.
Saturday 6:02 p.m.
The order comes in on WhatsApp
Eduardo, who owns a building-supply yard, got a request from a foreman for cement for Monday. He writes: "I need 600 bags of cement and 2 tons of 8mm rebar for Monday." The order desk is closed; Sellium answers in seconds.
6:03 p.m.
Identified without an account number
The agent recognizes him by his business name and delivery zone against Salesforce and the ERP. It asks for no login, customer number or form: it already knows who he is and on what terms he buys.
6:04 p.m.
Real stock and channel price
It checks stock at the nearest plant and quotes with the dealer channel price list, volume discount included. The price Eduardo sees is the same one the system invoices.
6:05 p.m.
Trade account and financing in the chat
It checks the account balance and credit limit. Since the order goes over the limit, it offers bank financing in installments and confirms it without leaving the conversation.
6:07 p.m.
Order loaded, certificate attached
The order is logged in the ERP with the batch's IRAM quality certificate attached and delivery scheduled for Monday at 7 a.m. at the job site.
On Monday at 7 a.m. the truck unloads at the job site with the delivery slip and the batch certificate. An order that used to wait for Monday morning and a free phone line came in and was loaded in five minutes, on a Saturday night, without adding headcount.

Public benchmarks for the channel, not our own results: every Sellium implementation is measured against a baseline agreed with the customer (order lead time, self-service rate, OTIF, cross-sell).

Frequently asked questions about Sellium for Construction Materials
Can Sellium handle differentiated pricing by customer, job site and channel?
Can Sellium handle differentiated pricing by customer, job site and channel?
Yes, and in Construction Materials it is the price of entry: the quote combines the current price list, the channel (dealer, contractor, installer, retail), volume discounts and contract terms per job site, and it is confirmed against the ERP before the order closes. The agent does not improvise prices: it answers with data from your systems.
How does the dealer get identified without an account number or login?
How does the dealer get identified without an account number or login?
By any detail the customer does remember: tax ID (CUIT), business name or delivery zone. Sellium matches it against Salesforce and the ERP and retrieves the account with its price list and history. Zero portal, zero password, zero friction.
Can it take ready-mix concrete orders, which cannot wait?
Can it take ready-mix concrete orders, which cannot wait?
Yes, and it is one of the sector's most demanding cases: it takes quantity, grade (H-21, H-30, H-40), exact day and time and unloading method, checks the nearest plant and the product's shelf life, and coordinates delivery with the job site. Mixer truck logistics and digital proof of delivery are handled by Trazzo, the suite's last-mile agent.
Does Sellium replace the B2B portal or the ERP?
Does Sellium replace the B2B portal or the ERP?
It does not replace anything: it integrates with your current stack (SAP S/4HANA Building Materials, Oracle JD Edwards, Dynamics 365, NetSuite and others) via API. The portal can stay; what changes is that the dealer no longer has to use it to buy. The permissions and security model is on our security page.
