Sundry Invoice

DEFINITION: A sundry invoice, also known as a miscellaneous invoice or an ad hoc invoice, is a billing document that accounts for various small or infrequent transactions in a business.

These transactions can include small sales, reimbursements from employees, rental fees, petty cash disbursements, service charges, or any other financial activity deemed necessary to be recorded and billed separately.

It includes information such as the description of the item or service, quantity, unit price, applicable taxes, and any additional charges or discounts.

They are generated on an as-needed basis to account for irregular or unpredictable transactions, allowing businesses to promptly bill clients or accurately record financial obligations.
