While cost data imported from Google Ads and a number of other ad services doesn't include VAT by default, for some ad services, you need to exclude VAT when setting up a pipeline. This will ensure that you get an accurate analysis of comparable metrics from all your ad services.
The services that export cost data excluding VAT by default are Google Ads, Facebook, Bing, AdRoll, Sklik, Twitter, Outbrain, Yahoo, myTarget and Criteo.
