Account aggregators make organizing your accounts and tracking your expenses easy, no matter how many accounts you have. The aggregator will show all of your linked accounts on one web page and will automatically assign categories to the transactions in each account. Aggregators are an easy way to check your spending, especially if you have several bank and credit card accounts to keep track of.
