Many of us these days have multiple accounts, some we use everyday, others less frequently.
With the Marygold app you can link as many external current accounts as you like, and then create as many low-balance alerts as you wish.
Low-balance alerts can be used to help make sure your external current account(s) do not go overdrawn, and they can be useful for general cash management (e.g. you may just wish to create alerts if your business current account dip below much higher levels just for your own sanity).
