reikningum

Reikningur is an Icelandic noun meaning an invoice, bill, or accounting statement. In plural, reikningar, the word covers multiple invoices, while reikningur can also refer to a ledger entry or an account in bookkeeping. The form reikningum is the dative plural form of reikningur, used when the invoices are the indirect object of a sentence (for example, referring to payments or references to multiple invoices).

Etymology and sense: The term comes from the verb reikna, “to reckon” or “to count.” The sense of a calculated record of amounts owed developed into the modern meaning of an invoice, as a formal request for payment detailing goods or services provided.

Usage in business and accounting: A reikningur is typically issued when goods or services are provided. It commonly includes the seller and buyer, date, a unique invoice number, itemized descriptions, quantities, unit prices, subtotals, applicable taxes, and the total amount due. In Iceland, invoices are often sent electronically, and payment terms are stated on the document. Invoices are also used in bookkeeping to track revenue and to prepare financial statements, and they play a role in VAT (value-added tax) reporting.

Related terms: Reikningur also appears in phrases concerning accounts and bookkeeping (reikningsskil, bókhald). The plural form reikningar is used when referring to several invoices in the nominative, while reikningum serves as the indirect object form in sentences.
