Adding budget to a channel
If you use channels and moments for your media plan, this one comes in pretty useful. Integrate your planning with your budget.
For every moment you add, you can input a budget. This will create a cost in Budget for the correct fiscal year. If you add more moments with a budget, this cost will be the sum of those budgets.
When you start receiving invoices for that channel you can add them in Budget in the autogenerated cost.
What if I have one budget for the campaign and multiple dates?
Simply add your budget to one of the dates. It might be a good idea to add that amount to the date closest to the expected invoice date.
