Should I put in a lump sum and jump from one cash management account to another or split up between different cash management accounts?

What's the purpose of this cash? Is it emergency funds? Or for investment?

Emergency funds - the key consideration is keep it close by, and have quick access to it. Don't put it somewhere that will take days for the cash to come back to you when you need it urgently.

If it's for investment, there are many better solutions than cash management.

If it's savings for a short-term goal like house, car, wedding - look at the goal horizon and invest it accordingly.

Also, if you're stressing over hopping from one cash management product to another, I wrote an opinion on this Q&A thread, you might find it useful.​​​
