You receive a month-long IO from a client for a new campaign with a $10,000 budget.
To manage this:
Create a new campaign (or duplicate an existing one).
Set a campaign spending limit of $10,000.
Ensure the start and end dates for the ad sets in the campaign align with dates of the new IO.
Make sure the sum of the budgets for the active ad sets in this campaign reflect that you want $10,000 to be spent over the course of the month. The campaign spending limit is an un-paced limit, so for smooth pacing, make sure the sum of the budgets for active ad sets in this campaign reflect that you want $10,000 to be spent over the course of the month.
The IO is increased to $15,000.
To manage this:
Edit the campaign spending limit for the existing campaign to $15,000.
Ensure the sum of the budgets for the active ad sets in the campaign reflect that you want to spend $15,000 over the course of the month, starting from the original start date of these ad sets.
The IO is decreased to $9,000.
To manage this:
Edit the campaign spending limit for the existing campaign to $9,000.
Note: This can only be done if the amount spent on the campaign so far is at least $100 less than the new limit. In this scenario, that would mean no more than $8,900 could be spent so far in order to lower the limit to $9,000.
Ensure the sum of the budgets for active ad sets in this campaign reflect that you want $9,000 to be spent over the course of the month, starting from the original start date of these ad sets.
The IO is delivered in full by the end of the month. You receive a new IO for the next month with a budget of $20,000.
You have two options for setting a new campaign spending limit here:
Option 1: Start a new campaign
Create a new campaign (or duplicate existing one).
Set the campaign spending limit for the new campaign to $20,000.
Ensure end date for the ad sets in new campaign align with end date of the new IO.
Option 2: Continue working on an existing campaign
Raise the campaign spending limit on the existing campaign to $30,000.
Crucial: The campaign spending limit on an existing campaign will always reflect prior spend, even if the limit is removed and then reapplied. In this case, the campaign has already spent $10,000. In order to allow for an additional $20,000 of spend, the campaign spending limit must be set to $30,000 (previous spend of $10,000 + new IO amount of $20,000).
