Immediately after a client completes a transaction, the information is instantly transmitted to the corresponding blockchain network. Transaction confirmation time is determined by the type of digital currency used, the network load, and the established fee.

Most often, the confirmation process takes from a couple of minutes to about a third of an hour, until the required number of blocks confirm the transaction's success and the final amount arrives in the recipient's wallet.

Even if full payment is received after the invoice expiration date, the funds will still be processed after receiving at least two network confirmations.
