No commitment. Just context, judgment and clarity.

Every day a car sits on the lot costs you money. We advertise the inventory that needs to move, send interested buyers straight into a conversation and track what each contact cost, car by car, so the budget goes to what sells.
A used-car dealership sells inventory that changes every week to a buyer who researches, checks the price guide and makes up their mind in a conversation. Brazil saw 18.5 million used vehicles change hands in 2025, a record in the FENAUTO series, and 4.6 million used vehicles were financed that same year (B3). That's why the ads have to keep pace with the lot, the conversation has to start on WhatsApp with the right car already in the message, and the yardstick isn't likes or clicks: it's cost per conversation, car by car, and how many conversations turn into visits and sales.
A generic ad competes for attention with every dealer in town. In the used-car dealership case in Curitiba, the inventory showcase video drove 453 conversations at BRL 2.35 and an ad for two cars priced to move drove 150 at BRL 1.16, while the generic "SUV festival" ad came in at BRL 20.44 per conversation.
Dealer inventory turns over every week, and an ad for a car that's already gone starts conversations that frustrate the buyer and burn budget. The campaigns follow the lot: in the Curitiba case, there were 49 campaigns in three and a half months, launched in batches alongside new inventory.
Car leads go cold fast. Companies that tried to contact a lead within an hour were nearly 7 times as likely to qualify it as those that tried even an hour later (Harvard Business Review, 2011). A good ad with a slow reply turns into a paid conversation for a competitor to close.
A cheap click doesn't move a car off the lot. The yardstick is cost per conversation, car by car, and how many conversations turn into visits and sales. In the Curitiba case, cost per conversation dropped from BRL 7.95 over the previous 12 months to BRL 5.63 with NWLAB, 29.2% lower.
Before any ad spend: inventory organized car by car, with model, year, price, photos and a short video, a WhatsApp button with a prefilled message on every ad and the conversation tracked as a conversion. Without that, there's no way to know which car brought in each contact.
Two fronts run side by side: the inventory showcase video, which introduces the dealership and what's on the lot, and single-car ads for the units that need to move. In the Curitiba case, the showcase video drove 453 conversations at BRL 2.35 each.
A car that sells comes down the same day, and a new arrival goes up with its own creative. Changes go out in batches, every week or with every big inventory intake, so the account never advertises a car that isn't there anymore.
The lead arrives on WhatsApp with the advertised car already in the message. A fast reply, extra photos and video, a financing estimate and an invitation to come in: the campaign only pays off if your sales team is ready for that conversation.
Every week, budget comes off the cars that don't generate conversations and goes to the ones that do. What we track is cost per conversation by car and by creative, how many conversations turn into visits and how long each car takes to leave the lot.

Our prices are public: setup, monthly management per channel and a fee on ad spend, with media starting at $1,500 per channel per month. In the used-car dealership case in Curitiba, the account spent BRL 13.7k on media over three and a half months, with 2,433 WhatsApp conversations.
On Meta (Facebook and Instagram), the car ad takes the shopper straight into a WhatsApp conversation, and that's where the Curitiba case ran. On Google, searches for a specific model or for used cars in your city reach people who are already deciding. The right mix depends on your inventory and budget, and the diagnostic sets where to start.
Yes, carefully. On Google, automotive advertisers promoting consórcio (Brazil's pooled car-buying plans), financing or car insurance need the financial services verification required in Brazil. The copy for any credit offer is reviewed before it goes live.
Because buying a car gets settled in a conversation: price, trade-in, financing and a visit. In the Curitiba case, the campaign optimized for conversations brought in 2,433 of them in three and a half months. The website is there for shoppers who want to browse the whole inventory before reaching out.
The first read on cost per conversation comes in the first few weeks, once each car has had enough budget to compare. After that, optimization never stops: any car that doesn't generate conversations loses budget every week.
Yes, on the used and pre-owned side, which is where we have a case study. For new cars, the campaign is built differently, and that comes out of the diagnostic.
No. NWLAB brings the conversation to your store and can automate the first reply, with the advertised car, photos and the next step, but your sales team negotiates and closes the deal.
