The customer BP invoice entry function is used to manage the customer invoicing out of the “typical” sales cycle.
In this context, the user does not manage the order, the delivery note with the stock issue etc. When issuing the invoice, the data necessary to the accounting are saved.

We may need a basic important points to make a sales invoice such as:

1. Customer
2. Account
3. Site

Account: A generalledger, also known as a nominalledger, is a bookkeeping ledger that serves as a central repository for accounting data transferred from all subledgers like accounts payable, accounts receivable, cash management, fixed assets, purchasing and projects. Each account maintained by an organization is known as a ledger account, and the collection of all these accounts is known as the general ledger. The general ledger is the backbone of any accounting system which holds financial and non-financial data for an organization.
