If you use ADXL as your delivery platform, you'll pay for your ad spend in each ADXL campaign. All the channels will be combined, and you'll pay a single payment based on certain thresholds, like a maximum amount or a number of days. For instance, if you're a new account holder, you'll be charged once your spend hits USD50 or at the end of each day, whichever comes first. As your account becomes more experienced, the thresholds will rise automatically.
However, if you connect your Facebook, Google, LinkedIn, TikTok, Twitter, or other ad accounts to ADXL, your ad spend won't be charged by ADXL. You'll be billed separately for each individual ad account. For instance, your Facebook ad account will have its own billing cycle and charges, and you'll pay it as usual.
