I would like to get a copy of all my transactions with adwords for 2016 please
When you are logged into your account, click the gear icon at the top right of the screen and select "Billing." If you have an older account it might say "Adwords Billing". This will load the transactin history page. Look for the drop down menu which will be set to "Last 3 months" and change it to "Previous year." This will show you everything for 2016. Clicking on Export will allow you to print it or export as a .csv.
