Does Amount Due -0.03 on a statement mean that they owe you 3 cents?

Let's use the example of an electric bill. Let's say you owed a month's electric bill of $329.47 cents. However, you like to work with even numbers or cents. So you pay $329.50. This would show as a "credit" to you of -0.03 means they are holding 3 cents in your favor. If you had paid $330.50 (on 329.47) to make a even more "even" payment, you'd be owed $1.03 (written on the statement as -1.03). But on the same statement, which serves as your next bill, you also owe a new bill of $360.28 cents. If you want everything to be even---so they owe you nothing and you owe nothing---you would pay $360.25 which would make a zero balance owed/due on both sides, at least until your next bill arrives.

Do you know... If you end services from a company and will not use them again anytime soon, and you have a 3-cent credit (meaning in your favor), the company must send you a check for that tiny 3-cents. They don't get to keep an overpayment (e.g. a credit owed to you). If, however, you continue to use the company, just let that credit fold into your next payment, so the balance due and balance now become zero.
