How to use / 使用方法
- Enter only rough balances, bill amounts and timing assumptions—never account numbers or login details.
- Compare the transfer arrival window with the date a debit, bill pay or card autopay may post.
- If the timing gap is late, verify faster funding, backup payment and overdraft rules through your bank.
- Use the linked online-bank comparisons only after confirming current official terms.
