A Script to receive Daily Budget Overdelivery Alerts

Here’s a script that will alert you if and when the latest Daily Budget change by Google will cause Google to overdeliver and spend more than your daily budget.
The script will compare the anticipated ad spend based on your campaign daily budget settings with the actual ad spend.
It will check for overdelivery in any of three periods: yesterday, last week and last month.
In case of big differences (overdelivery by Google) it will report an alert, log the alert in the specified Google Sheet and inform you about the alert via email

Here’s what the output will look like:

 

Don’t worry if you have never run an Adwords Script before. It is fairly easy if you follow these steps on how to set up and run Adwords Scripts.

Be sure to create a new empty spreadsheet and add the url to the script. Also add your email adress. (lines 28 and 29)
You can also set the threshold variables to whatever percentage of overdelivery is acceptable to you. (lines 36 to 38)

You can schedule the script to run daily. If you do so, change the ‘firstRun’ to false (line 33).

Here are some instructions on how to install the script if you’ve never done so before.
