An invoice for payment is a billing document issued by a seller to a buyer to initiate a cashless bank transfer for goods, works, or services.

It includes the parties’ details (name, address, tax IDs), the recipient’s bank information (bank name, BIC, correspondent and settlement accounts), invoice number and date, payer, contract reference, line items and totals, payment term, and authorized signatures. 

It serves as a basis for initiating a bank transfer and speeding up internal approvals, but it does not replace closing documents (service act, UTD, or waybill).

When it is used:

• Before prepayment or final settlement under a contract for goods or services.
• For non-cash B2B payments between companies and sole proprietors.
• For recurring subscription/retainer payments under service agreements.
