Thank you, KJ. Good morning, and welcome to our fourth quarter 2020 earnings call. To begin, I'll talk about 2020 and then comment on recent developments. Following that, our CFO, Paul Rouse, Paul Rouse, will provide insights on our Q4 numbers and an update to our 2021 guidance, and then we'll open it up for questions and answers.
In 2020, we had a big year. We became a public company again on the NASDAQ. We refreshed our Board of Directors and brought in real SaaS and software talent expertise to help us accelerate the growth of our SaaS business. We launched our own payment platform, Paul Rouse. And most importantly, we returned our SaaS business to grow. We're really proud of these milestones in 2020 because, let's face it, there were unprecedented challenges for small businesses this last year. And we were inspired and impressed by the way small businesses worked hard to stay in business and just were determined a persevere. And our team actually, I think, played a pretty big role in helping a lot of small businesses adapt and make it and figure out how to really alter their business model using the software to be able to do e-commerce or to be able to become a business that delivers or whatever to make it through those really difficult shutdown situation. We're really impressed by that.
2020 was really an explanation point on this need for small businesses to modernize and transition to the cloud. We believe that the changes that the pandemic brought about are durable and will forever really accelerate the transformation of small businesses using cloud tools and digitizing their business. So we think there's a really strong foundation for our growth coming off of that.
I'd like to talk a little bit about growth, churn, ARPU, some of the things happening in our business. Our SaaS platform grew 8 -- a little over 8% in the fourth quarter. Our churn is down and has been steadily coming down. We're at a level now that I would describe as par. We probably aren't going to do a whole lot better because we are dealing with modern top small businesses, and there is some ins and outs there. So it's very acceptable in our models, we can get really strong growth being kind of in this mid- 2s churn level. We think that's around the right place to be.
Our ARPU has been improving, improving because we made a big shift in our strategy. We had experimented with going down market. We've moved back up market, selling to a little bit bigger businesses, selling a little bit more complete robust solution, a little higher price point. We're getting really fully engaged customers. We've been disciplined about our ideal client profile, getting the right customers in. And consequently, you're seeing ARPU or spend for customer rising nicely, I would encourage you to take a look at those stats. And while our client growth is about flattish, we're looking to see that begin to accelerate as we go through this year as those smaller or less engaged customers roll off, and we're bringing in the larger ones that are spending more and much, much more committed and are truly using the software. So we're looking forward to having not just revenue growth, but also client growth as this year goes on.
The big story for us over the last year or so is engagement. We've seen tremendous growth in engagement. And engagement, I would describe as people that we see active in the in box using it. We see them adding contact cards to their CRM. We see their scheduler lining up with people scheduling appointments with them. We see them sending out marketing automation campaigns using our console for social media. And maybe most importantly, we see the payment volume. We see them accepting more and more payments in broadband.
So that really shows us what's happening in that business. We recently hit an all-time high of active users with daily and weekly user growth up the most. It's up tremendously year-over-year. And we think we're going to continue to invest in education and engagement growth, we've been really building our client success team actually investing in more and more people to just spend time with those customers teaching showing. Remember, we're bring in the unclouded into the cloud here. So it requires a little handholding.
Sensis, the acquisition we made in Australia closed March 1. It has over 100,000 small business clients. It's a marketing services business that really is a whole lot like the slide business here, just minus the software that's a big zoo, 100,000 customers for us to hunt in now and really expand our SaaS business. Their performance in Australia has been arguably world's best. They have the advantage of the white pages, which their white pages business outperforms the yellow pages business with a slower revenue decline and higher margins. In fact, they've delivered margins north of 40%. So John and his team are really good at this. High free cash flow generation, this thing is throwing off a ton of cash. You'll be impressed by just the amount of commonalities between the 2.
Now I've known John Allan, he's been in that job for over 8 years. I've known him for most of that time. We've been business friends. He's come here to the U.S. multiple times to meet with me and our team, and I've been to Australia, and met with he and his team. Our teams have talked and shared best practices and ideas. So there's a good warm feeling between the 2 companies. I really like John a lot, and I think you will too, I want to take this time and introduce you to John Allan and have him just have a word with you. John?
