Business Cash: APY and Liquidity
Business cash trades yield against liquidity: checking is convenient but low-yield; savings, money funds and short Treasuries pay more but may have transfer or redemption limits. Keep one to three months of operating cash first.
Layering
Operating: checking for one to three months of expenses.
Reserve: high-yield savings/money funds with T+0/T+1 access.
Idle: short Treasuries/CDs with a lock-up.
Do not chase APY alone
Check fees, minimums, insurance structure and transfer limits.
Confirm early-withdrawal penalties and redemption rules.
