I've almost forgotten HOW to write a check!
My bank & credit union offer bill pay services but, I generally go to the website of the creditor and pay through them which gives me the ability to select which account I want to use at that time. I like to check my bank accounts daily and this keeps my balances correct and verified.
It's fast, easy and so convenient! You can set up a date for the payment to be made, in advance, you can change the payment at anytime BEFORE it is put thru, if needed. Wonderful to be able to jump on line and take care of that "OH, NO!" tomorrow it's due and I forgot to mail......geesh, it's a great thing to just sit, type and be done
My accounts then email me a confirmation of the payment. Of course, any can be printed if you want that. I don't get bills in the mail anymore, you can download entire statement on line. And with auto-deposit of payrolls, pensions, etc....gosh, it's easier to live in the boonies.
Been doing it for about 10-12 yrs now. No problems.
