This module handles the recording of transactions in your cash registers and bank accounts, as well as the creation of payment orders. Cash register and bank items can be matched with records in invoicing, receivables, and payables. For both cash and bank documents, it is possible to enter a summary number — for a bank statement this is the "statement number," and for a cash document it refers to the identifier of a grouped cash document (where several receipts are posted using a single cash document).
