NOTE: I mention that this is for people spending a lot on ads. I thought about it a bit, and a custom solution like this could have utility, too, if you just wanted to assemble all your monthly sales / expense reports in a single spreadsheet or dashboard without manually inputting all the data. Especially if you’re wide. So even if you’re spending modestly on ads, it could have other use cases. But probably the most useful one is when you’re running ads on multiple platforms.
