Google and Amazon need up to 14 days to provide all information regarding costs and sales, such as refunds for unauthorized clicks. Adspert's billing is then based on this final data.
In order to take these facts into account and include them, Adspert's billing starts a few days after the end of the month. As a rule, you can expect the billing for Google, Bing and Yandex around the 5th of the following month and for Amazon around the 15th of the following month.
If you have both platforms optimized by us, you will receive the total invoice around the 15th of the following month.
