Betterlane vs Revenda Mais: a WhatsApp assistant for used-car dealers in Brazil
Betterlane is for the used-car store in Brazil that wants WhatsApp answered well without changing its system: we build and run the assistant on the number the store already uses, through the official WhatsApp API, with the store’s own answers and rules. It answers when no salesperson does, asks which car the customer wants, how they plan to pay and when they can come in, and hands over to a salesperson with a summary. No setup fee, live within 10 days, month to month with no lock-in.
Choose Revenda Mais if the store’s stock already lives there and you want the assistant to answer from live stock, with 30+ listing portals and the CRM in the same system: its AI SDR depends on the stock being kept in Revenda Mais. Our assistant does not read stock and never confirms that a car is available; the salesperson does.
The price, in writing first
The price is given on the 20-minute call and agreed in writing before we start, together with what the assistant must do. Month to month.
Check it yourself
The assistant’s code is covered by 72 automated tests, which run before any change goes live; all 72 passed on 7 Oct 2026.
Where the data goes, in short: the assistant and its database run in the region closest to your customers (São Paulo for the Americas; London or Frankfurt for the UK, Europe or the Gulf, set up before day 1); replies are written by OpenAI’s model through Vercel’s AI Gateway with zero data retention, in US data centres, or EU ones for Europe; we do not publish a standard data processing agreement yet. If your customers’ data has to stay in one country, check this before anything else.
Betterlane and Revenda Mais side by side
| Betterlane | Revenda Mais | |
|---|---|---|
| What it is | An agency: we build and run the assistant on the store’s WhatsApp | A management system for used-car stores (stock, CRM, portal integrator, invoices, websites) with an “IA SDR” that answers and qualifies WhatsApp leads from the store’s stock12 |
| The store’s system | No system change: the salesperson gets a note with the summary, and the store keeps what it uses | The AI SDR depends on stock kept in Revenda Mais; leads go into the CRM automatically only for stores on the system1 |
| On WhatsApp | Answers when no salesperson does (after hours, and during hours after 4 minutes with no reply), only from the information the store gave; asks the car (model and year), how they will pay (cash, financing or a trade-in) and which day and time of day they can come in | Answers “in under 2 minutes, 24 hours a day, 7 days a week” (translated), qualifying from stock1 |
| Stock and portals | Does not read stock: never confirms that a car is available, and says the salesperson will confirm | Reads Revenda Mais stock and connects “more than 30 portals” (Webmotors, OLX, iCarros) plus Facebook and Instagram ads (translated)12 |
| Handover | Sends the salesperson a note with the customer’s name, the car, the payment method, any trade-in and the day they want to come in; the salesperson confirms. Hands over to a person when the customer asks or complains | “Generates a detailed summary in the CRM and alerts the salesperson” (translated); does not negotiate the final price or sign contracts1 |
| What it never does | Never confirms availability, never states a price the store has not published or given in writing, never quotes instalments, rates, down payments or financing approval, and never values a trade-in | Never invents cars, never changes prices or grants discounts, never promises a trade-in value without inspection1 |
| WhatsApp number | The number the store already uses, through the official WhatsApp API; Meta’s fees, if any, stay on the store’s own account | The store’s official number through Meta’s API (“we handle the whole integration”, translated); recommends a separate number for the AI1 |
| Setup | Built and run by Betterlane, with no setup fee; live within 10 days of receiving WhatsApp Business access and the store’s information | R$ 390 setup on the CRM plan, with “1 remote training” and “30 days of follow-up” (translated)2 |
| How it is priced | The price is given on the call and agreed in writing before we start, with no setup fee. Month to month, with no penalty or lock-in | CRM + WhatsApp plan: R$ 350 a month + R$ 390 setup (3 users); the AI SDR has no published price (demo form only)21 |
When each one is the better choice
- Betterlane when the store wants to keep the system it uses, wants the WhatsApp answering built and run by a team, with clear rules on price, financing and trade-ins written before we start, and wants to start with no setup fee, month to month.
- Revenda Mais when the store’s stock already lives there (or will), and you want the assistant to answer from live stock, with portals, CRM and invoices in one system.

Questions
What exactly is guaranteed?
Five points, written before we start: it answers when no salesperson does, only from the store’s information; it asks the car, the payment method and the day of the visit; it sends the salesperson a note with all of that; it never confirms availability, a price the store has not given, financing or a trade-in value; and it hands over to a person when the customer asks or complains.
Do we have to change our system or our number?
No. The assistant runs on the WhatsApp number the store already uses, through the official API, and the salesperson gets the notes without the store changing systems.
Does the assistant book the test drive?
It asks which day and time of day the customer wants to come in and sends that to the salesperson, who confirms with the customer. Nothing is booked without the salesperson.
