Whenever pricing is updated in our system, the changes are immediately pushed to the listings in your connected channels. This means that as soon as we receive pricing data from PriceLabs, we send it to the connected channels, with the applicable markups.
You can read more on PriceLabs schedule for pushing prices on their help centre.
You also also has the ability to manually force pushing your prices at anytime. From PriceLabs, you can go on your property page and click "Sync Now". You can read more about this PriceLabs feature on their help centre.
