Biller

Biller is a term used in business to denote a person, department, or system responsible for issuing bills or invoices for goods or services. The word comes from bill + er, forming an agent noun.

In practice, a biller may be a staff member in accounts receivable, a dedicated billing department, or a software component that generates and sends invoices, applies pricing, taxes, and discounts, and records transactions. Billers ensure accuracy of customer data, manage payment terms, and monitor receivables.

Contexts vary: in healthcare, medical billers prepare and submit insurance claims after coding services; in utilities, telecom, and retail, billers issue periodic statements and support payment processing. Modern organizations often use automated billing systems within ERP or CRM software to streamline invoicing and collections, sometimes including electronic payments and reminders.

Technology and standards: Biller systems may support electronic invoicing (e-invoicing) and interoperability through standards such as PEPPOL and UBL, enabling cross-border invoicing and faster settlements.

The term is used primarily in English and refers to the agent or process of producing invoices; it can correspond to invoicer, billing clerk, or accounts receivable clerk depending on context.
