The cost of silence
While your company decides, the clock runs against you
Every inquiry your company fails to answer in time is a sale that walks to a competitor. This calculator estimates, with example assumptions you can adjust, how much slips away every month.
An estimate based on an example scenario, with adjustable assumptions. Not a measurement of your company or a guaranteed result.
Contacting a lead within the first hour makes you nearly 7 times more likely to qualify it than an hour later (Harvard Business Review, 2011). And responding within the first 5 minutes makes you 21 times more likely to qualify the lead than waiting half an hour (Oldroyd, MIT and InsideSales.com, 2007).
The inquiries that arrive at night, on weekends and on holidays pile up unanswered, because your sales team has working hours and your customer does not. By the time someone replies, the customer has already bought from whoever answered first.
It is not an effort problem: it is one of capacity and hours. At peak demand, even adding salespeople will not get every message answered within the first minutes, which is when the customer decides. That is the window your company keeps missing.
True understanding
It understands how your customers actually write
No menus, no keywords, no 'press 1'. Sellium interprets the real message, slang and typos included, and replies the way your best salesperson would.
“do u have the 205/55/16?”
Inquiry for a 205/55 R16 tire
“how much is the same one but in 17”
Price for the 17-inch variant
“any deal if I take 4?”
Volume discount request
“can I pay in installments?”
Financing inquiry
“hey!! got the 16?? 🙏🔥”
Behind the emojis: an inquiry for the 16-inch. The noise doesn't throw it off
Transcribes and interprets the audio: they want four 205/55 R16 tires by Friday, delivered to the south side
Text, voice, emojis, or at 3 in the morning. It understands all the same.

Automotive
Dealerships lose sales when a customer asks about a used car on a Sunday and no salesperson is around. Sellium answers with real inventory including mileage, year and registration, calculates the monthly payment at the current rate and books the test drive on the spot.

Comparisons
Sellium versus how you sell today
Managed service
Not software for you to assemble. A turnkey agent
Low-cost self-service platforms are like flat-pack furniture: a box, screws and a 47-step manual. You do the work.
We hand it over up and running. You never pick up a screwdriver.
We don't sell software. We sell results.
Implementation
Up and running in 4 to 6 weeks
Discovery
We map your sales process, your catalog, your pricing rules and your channels. By the end of this stage, the agent's scope and the priority use cases are defined.
Build
We configure the agent, connect it to your systems (CRM, ERP and payment providers) and train it with your real data.
Validation and launch
Tests with real cases, fine-tuning and progressive activation in production, with our team alongside you at every step.
What happens to your customers' data
The same security banks and regulated companies require, on the platform you choose.
Your data stays yours
Zero Data Retention with LLMs. We never use your information to train models or for any purpose beyond what you contracted.
Official WhatsApp, in your company's name
Runs on Meta's official WhatsApp Business Platform, with no unofficial apps. The account is opened in your company's name, not Vantegrate's: the number is yours and portable.
Payments with PCI DSS providers
In-chat payments are processed by PCI DSS-certified providers, with encrypted communications and access controls.
Signed data agreement
We sign data processing agreements, comply with local data protection laws, and every operation is audited and traceable.
Frequently asked questions about Sellium
What sales teams usually ask before automating their WhatsApp sales.
How is Sellium different from a traditional chatbot?
How is Sellium different from a traditional chatbot?
A traditional chatbot follows a menu tree and matches keywords. Sellium is an AI agent: it understands natural language, keeps the context of the conversation, builds quotes and collects payment inside the same WhatsApp chat. It never redirects you to another channel or traps you in 'press 1'.
My products are technical. Can Sellium still sell them?
My products are technical. Can Sellium still sell them?
Yes. Sellium answers only with data from your systems (spec sheets, compatibilities, prices and business rules): it never improvises or makes things up. That lets it resolve technical questions that used to need a specialist, and when one truly does, it hands the conversation to your team with full context.
Don't my customers prefer talking to a person?
Don't my customers prefer talking to a person?
What customers want is a fast, accurate answer, without repeating themselves or waiting. Sellium delivers exactly that, around the clock. And when someone explicitly asks for a person, it transfers immediately to a salesperson with the full conversation history.
I don't have a technical team. What do I need to implement it?
I don't have a technical team. What do I need to implement it?
Sellium is a managed solution. Our team handles the configuration, the catalog loading, the integrations with your systems and the agent's training. Your team only validates and approves. No coding or technical skills required.
How is my customers' data protected?
How is my customers' data protected?
Security comes first. Sellium runs on Meta's official WhatsApp Business Platform, which tracks the quality of each number and warns before restricting it, not on the app or unofficial tools that end up getting blocked, with encrypted communications and access controls, and payments are processed by PCI DSS-certified providers. We sign data processing agreements, comply with local data protection laws, and every operation is audited and traceable.
Which systems does Sellium integrate with?
Which systems does Sellium integrate with?
Your CRM (Salesforce, HubSpot and others), your ERP, your e-commerce platform and your local payment providers such as MercadoPago. Orders and contacts sync automatically, with no double entry or manual reconciliation.
How long does implementation take?
How long does implementation take?
Between 4 and 6 weeks. The first two cover discovery (process, catalog and rules), the next ones configuration and integration, and the last ones validation with real cases and a progressive launch.
How much does Sellium cost?
How much does Sellium cost?
Sellium has two parts. A one-time implementation, quoted for each company, that covers mapping the processes you want to digitize, training the agent, integrating it with your systems and the adjustments you need. And a monthly subscription that includes AI credits to run the agent, with the option to add credits as your volume grows. There is no minimum term, and you pay WhatsApp messages directly to Meta. We put together a tailored quote in one short conversation.
There are cheaper self-service platforms. Why Sellium?
There are cheaper self-service platforms. Why Sellium?
Because we don't sell a toolbox, we deliver a working agent. Self-service platforms leave you the work of designing flows, loading the catalog, integrating and training the AI. With Sellium that work is included: we build it, connect it and maintain it.
