Bill

Bills are present in The Sims series of games, and must be paid in order to avoid a visit from the repo-man, who will repossess (take) household items in place of payment. Bills are paid using simoleons held in the family's account. If there is not enough money in the account to cover the cost of the bill, the bill cannot be paid. The value of the bill is determined by the value of the lot, including all items on the lot.

In The Sims and in college sub-neighborhoods in The Sims 2: University, bills are delivered to the lot's mailbox every three days. In The Sims 2 and The Sims 3, bills are delivered to the lot's mailbox on Tuesday and Thursday at 10:00 am. Bills are delivered to residential lots, as well as dormitories, Greek houses, and apartments.

To pay a bill, in The Sims and The Sims 2 until The Sims 2: Seasons, a Sim must first remove the bill from the mailbox, then the player must click on the bills and direct a Sim to pay them. Seasons introduced the ability to pay bills by clicking on the mailbox and selecting "Pay All Bills", though the bills must still be removed from the mailbox before they can be paid. The "Pay All Bills" feature is also in The Sims 3.

Any Sim teen or older may pay bills. In The Sims, a child can get bills from the mailbox, but cannot pay them.

After a period of time, bills will begin to change colors as they become over due. Bills start out as a white color, then change to yellow, then orange, then eventually red. After several days of non-payment, a message will appear warning the player of delinquency. In The Sims 3 the player is given the option to pay the bills then. If the bills are not paid before the end of that day, a Repo-man will arrive on the lot and repossess items roughly equal in value to the debt owed and in some cases more. The Repo-man in The Sims 3 will repossess the item that is closest to the debt but not under it, meaning he will almost always repossess items that are worth more than the bill payment was.

Bills and the repo-man can be "devastated" using the No Bills Ever lifetime reward. This costs 15,000 points. Additionally, In The Sims 2: Mansion and Garden Stuff and The Sims 3: Ambitions, Sims can purchase green sources to reduce bills by 0.2% per solar panel and windmill until up to 2%. Bills will occasionally refund the household if there are enough green sources on the lot.
