Counting and Summation Question

Here is the data I am dealing with. Two columns ID and Type:

ID Type
1 Report
1 Report
1 Workflow
2 Form
3 Report
3 Form

I need to summarize this as:

Report 2
Workflow 1
Form 2

I need to only count the same Type with the same ID once. Currently I am using COUNTIF but that counts report with id 1 twice. Also wanted to add that ID can be alpha neumeric

Thanks,
