I swapped to PriceLabs a couple months ago. I was hesitant, I didn’t really want to spend money when airbnb has a free smart pricing option built in. Similar to you, I also used airbnb’s promos.
I did the free trial on PriceLabs and revenue had a small uptick. I decided to sign up when the trial was over because they don’t require a long term contract. Revenue stayed high (and increasing) so I’ve continued to use it. It’s not a magic bullet and I didn’t make A TON more right away.
I log in every Sunday night for 5-10 minutes and adjust settings slightly to keep it dialed into the market. So it’s not a one and done. But I was constantly looking at airbnb pricing so that doesn’t bug me.
You mentioned airbnb still running promos and it combining with PriceLabs. Totally true. I had that bite me on a couple long term stays where discounts were layered. Not a big deal and easy to correct. But you might considering adding some restrictions while you’re getting used to the changes.
Let me know if you have any specific questions, I'm happy to help if I can!
