Proof from the Shop Floor.

When shops start closing more sales and working smarter, they talk.
Here’s what they’re saying about partnering with Grand Onyx.

I am really jazzed on this idea you have (what GrandOnyx have been doing for us as a whole) It really has been nearly immediately and absolutely effective. This is some Kool-Aid that I like drinking!

Thank you Tim. I really do appreciate everything you guys have done up to this point and am so excited about the future with you and your company.

At our sales meeting this morning, one of my best reps that prides himself in using your system to connect with prospects was almost in tears because he cant keep up with all the new work coming in.

I’ve shown the website to quite a few people in the company, and every one of them loves it. And the first thing they notice is, ‘wow, there’s people in every picture.’ It’s super exciting, and I mean this obviously has a big impact.

Sales were down last year just like everyone else — but in 2025, both January and February set new monthly company records.

Nobody gets these kinds of close rates without Grand Onyx. Their clients are doubling what the rest of the industry is doing.

We had 21 walk-in customers in five hours on Saturday. We need to slow down and can’t throw 60 more jobs into the system right now all at one time… we had 130 retail quotes last week.

What I’m learning at this point is it’s about quality leads, and then getting the proper people and system to close them… And with what we’re doing with you guys, it’s so easy, compared to what we’ve got.

I really see the value in building this way… meaning your guys’s systems versus anything else. And you told me it would be hard because we’re from wholesale — and that’s where I’m like, at this point, it’s not hard.

Honestly, I don’t like managing anything, so for me it’s great because I get an email {from your Countertop Concierge} and there’s a lot of quality work done and somebody’s caring about following up on this stuff. So far, it’s been really good.

We’re seeing the trend go up. We took a hit on wholesale this year, but from my end, when I look at the data, things are going the right way — which is up.

I appreciate your guys’ know-how to do this… it reinforces to me to just stay out of the way.

Our leads are up… quoted leads are up 45%. We’re hitting our weekly goal by Tuesday.

We’re still in a culture shift, but we’re hitting goals week over week. We’re building a new facility and considering buying another machine.

Justin ended at $142K last month. He’s crushing everyone—even the reps with builder accounts.

Emma and Danelle have now asked for the same coaching I gave Justin.

Justin started texting in the last week and a half… and now loves it. He’s getting answers and moving deals forward.
Alex Stiffler

Justin takes more time with customers than they do… Maybe that’s the difference in his close rate.

Half an hour isn’t really enough for a retail client—it’s a $4-6K sale.
