Bill vs. Voucher: What's the Difference?

Edited by Janet White || By Harlon Moss || Published on December 25, 2023
A bill is a formal statement of charges or costs, while a voucher is a document serving as evidence for a transaction or entitlement.

Key Differences

A bill typically represents a request for payment for goods or services provided, showing itemized charges and the total amount due. In contrast, a voucher serves as proof of a right to a discount or service, often used in transactions as evidence for an exchange or redemption.
Bills are commonly issued after services are rendered or products are delivered, detailing the financial obligations of the buyer. Vouchers, however, are generally issued beforehand, offering a future benefit, like a discount or a specific entitlement, usable at the time of purchase or service.
In business, a bill is often a part of the accounts receivable process, where it signifies money owed to the issuer. A voucher, conversely, is used in accounting to authenticate transactions, acting as an internal control mechanism for expenses and reimbursements.
A bill is direct in its purpose: to inform the recipient of the amount owed. Vouchers, on the other hand, can be versatile, representing different forms of value such as gift vouchers, discount vouchers, or reimbursement vouchers, each with specific conditions and uses.
Bills are typically unilateral, requiring action (payment) from the recipient, while vouchers are more of a mutual tool, offering benefits to the holder while also serving organizational purposes like promotional strategies or financial record-keeping.
