# Double Your Revenue in 90 Days

https://motorgrowth.com/guarantee/ · Updated 2026-10-12

Doubling revenue in about three months was the most common goal owners named on our sales calls. So that's what we guarantee. Double Your Revenue in 90 Days applies to window tint, ceramic coating, PPF and detailing businesses that fit our criteria. The details are covered on the call.

## Does Motorgrowth guarantee results?

Yes. Motorgrowth's guarantee is Double Your Revenue in 90 Days. It applies to US window tint, ceramic coating, PPF and detailing businesses doing $5,000 a month or more that we take on as clients. We explain exactly how it works on the call before you sign anything.

## Why we offer a guarantee

Owners told us the same goals again and again: $8,000 to $16,000 a month. $10,000 to $20,000. $30,000 to $60,000. They wanted it in about three months. Many had been let down by an agency before and didn't want to take another bet on promises.

We only take on shops we think we can double: the right services, enough room in the calendar, at least $5,000 a month in revenue and $30 to $50 a day for ads. That's why we qualify on the call, and why we take one shop per area.

## What makes doubling realistic

Most shops we work with can already install and sell. Owners report closing 50% to 90% of genuine inquiries. What they lack is steady, qualified lead flow and someone to answer it. Fix those two and revenue can move fast.

- Ads that reach buyers in your area, live in as little as 7 days.
- A landing page that filters out price shoppers.
- A team that calls and books every lead.
- Cost per booking tracked from the first week.

## Frequently asked questions

### Is there a guarantee?

Yes: Double Your Revenue in 90 Days. It's the goal owners bring up most on our calls, so it's what we stand behind. We walk you through exactly how it applies to your shop before you sign anything.

### Where can I read the guarantee terms?

We go through how the guarantee works on the call, for your business specifically, before you sign anything.

### Why 90 days?

Because that's what owners ask for. On our sales calls, doubling revenue in about three months was the goal we heard most, from $8,000 to $16,000 a month or $30,000 to $60,000. Ninety days is also long enough for the ads to learn and the bookings to add up.

### Does the guarantee apply if I'm under $5,000 a month?

We don't take on shops under $5,000 a month. Below that, the fee and ad spend usually eat most of the extra profit, and we'd rather tell you that than take your money.

### Do I keep my ad account if I leave?

You do. The ad accounts, every lead and your landing page are set up in your business name from day one. If you ever stop working with us, all of it stays with you, so you never start from scratch.
