An invoice (from the 16th-century French word "envoyer", meaning "to send") is a legally recognized, time-stamped commercial document issued by a seller, contractor, or service provider to a client or buyer. It formally records goods delivered or services rendered, itemizes agreed quantities and unit prices, applies applicable sales taxes or discounts, and states the total amount due alongside clear payment terms (e.g., Net 30) and remittance instructions. Legally, an invoice establishes an account receivable for the seller and an account payable for the buyer.

An invoice number is a unique, sequential tracking code assigned to each invoice to identify transactions in accounting ledgers and tax audits. Common professional formats include: Sequential (INV-001, INV-002), Year-based (INV-2026-001, INV-2026-002), or Client-based (ACME-2026-01). You should never duplicate an invoice number, and you should always keep numbers sequential to satisfy tax compliance rules.

No, an invoice is NOT a receipt. An invoice is issued BEFORE payment is made to request payment from the client, stating what is owed, the payment terms, and the deadline. A receipt is issued AFTER payment is received as verifiable proof that funds have been settled. An invoice creates an unpaid debt, whereas a receipt confirms that the debt has been paid.

An e invoice (electronic invoice) is a structured digital invoice file formatted to international machine-readable data standards (such as XML, UBL, or JSON). Unlike a static scanned image or PDF, e-invoices are automatically processed, validated, and exchanged between enterprise ERP systems and national tax authorities (e.g., Peppol in Europe, GST e-invoicing in India, or Making Tax Digital in the UK) without human data re-entry.
