Can I Pay My Bills is a system for making sure you have enough money at a specific time in the future.
Here's an example.
Sure, it's just addition and subtraction, but it's hard to keep track of. CIPMB will tell you what your predicted balance is on each day. If your balance ever goes below $0, you have a problem that needs fixing.
To predict your balance on future days, all that is needed is your current balance and a list of expected transactions.
Most people don't. You don't know if your trip to the grocery store is going to cost $80 or $90. We recommend setting up an average that gives you a little wiggle room. Enter an expected transaction of $100 and then be happy knowing that you stayed under it.
Update your balance. If you went to a restaurant to eat last night, you don't need to enter that transaction. Just update your balance. CIPMB doesn't care about the past, only the future.
No. CIPMB only helps with future transactions, not past ones.
A little, but not really. Budgeting is the act of deciding how to spend your money. CIPMB will help you determine if you have enough money to pay for the things you've already decided to buy.
No. CIPMB is a good tool for your highly liquid assets - your checking account.
Definitely not. That's your business. Keep those account numbers to yourself.
