Create New Sale Invoice

public void NewSaleInvoice(AutoCount.Authentication.UserSession userSession, SaleInvoiceSource source)
{
    string newDocStr = "<<New>>";
    AutoCount.Invoicing.Sales.Invoice.InvoiceCommand cmd =
        AutoCount.Invoicing.Sales.Invoice.InvoiceCommand.Create(userSession, userSession.DBSetting);
    AutoCount.Invoicing.Sales.Invoice.Invoice doc = cmd.AddNew();

    doc.DebtorCode = source.CustomerCode;
    //if source.DocumentNo is null, then set DocNo as newDocStr
    doc.DocNo = source.DocumentNo ?? newDocStr;
    doc.DocDate = source.DocumentDate;
    doc.Description = source.Description;
    doc.CurrencyRate = source.CurrencyRate;
    doc.Agent = source.SalesPerson;

    //Set to apply rounding method of either by Document or by Each Line,
    //this may affect different result in GST Calculation due to decimal point.
    doc.RoundingMethod = source.RoundMethod;

    //Document Level Inclusive Tax
    doc.InclusiveTax = source.Inclusive;

    source.Details.ForEach(s => AddSaleInvoiceDetail(s, doc.AddDetail));

    try
    {
        doc.Save();
        //log success
        //AutoCount.AppMessage.ShowMessage(string.Format("{0} is created.", doc.DocNo));
    }
    catch (AutoCount.AppException ex)
    {
        //log ex.Message
        //AutoCount.AppMessage.ShowMessage(ex.Message);
    }

    dtl.AccNo = sourceDtl.Account;
    //When ItemCode is assigned, AccNo will be refreshed based on ItemGroup's SaleAccNo;
    //If ItemGroup is not maintained, then default Sale AccNo will be assigned.
    dtl.ItemCode = sourceDtl.ItemCode;
    dtl.Description = sourceDtl.Description ?? dtl.Description;

Implementation

public void MainEntry(AutoCount.Authentication.UserSession userSession)
{
    SaleInvoiceSource newDoc = new SaleInvoiceSource()
    {
        CustomerCode = "300-A001",
        Description = "SALES INVOICE GENERATED",
        //If let AutoCount auto assign running number, assign "<<New>>" is unnecessary
        //DocumentNo = "<<New>>",
        DocumentDate = new DateTime(2017, 11, 30),
        Inclusive = true
    };

    //There are many ways which data input can be entered into details, here are some of the common input.
    newDoc.Details.Add(new SaleInvoiceDetail() { Description = "Particulars" });
    newDoc.Details.Add(new SaleInvoiceDetail() { ItemCode = "FG00001", Quantity = 1, UnitPrice = 50.20M, GSTCode = "SR-S" });
    newDoc.Details.Add(new SaleInvoiceDetail() { ItemCode = "FG00001", Quantity = 2, UnitPrice = 50.20M, Discount = "5%", GSTCode = "SR-S" });
    newDoc.Details.Add(new SaleInvoiceDetail() { ItemCode = "FG00001", Quantity = 1, GSTCode = "SR-S", Amount = 50.20M });
    //Return stock is allowed, if the NetTotal is larger or equal to Zero after deduction.
    newDoc.Details.Add(new SaleInvoiceDetail() { ItemCode = "FG00002", Quantity = -1, GSTCode = "SR-S", Amount = -60.20M });
    newDoc.Details.Add(new SaleInvoiceDetail() { ItemCode = "FG00002", Quantity = -1, UnitPrice = 60.20M, Discount = "5%", GSTCode = "SR-S" });

    newDoc.Details.Add(new SaleInvoiceDetail() { Description = "Non-Stock Items" });
    //When AccNo & ItemCode both are not defined, system will retrieve from default Sale Account.
    //If default Sale Account is not maintained in Tools | Options, system will throw error on saving.
    newDoc.Details.Add(new SaleInvoiceDetail() { Description = "Misc. Charges", GSTCode = "SR-S", Amount = 30 });
    newDoc.Details.Add(new SaleInvoiceDetail() { Account = "500-0000", Description = "Transport", Amount = 50, GSTCode = "SR-S" });

    NewSaleInvoice(userSession, newDoc);
}
Non-Stock Item can either with or without ItemCode, it depends on the setting & preference of customer Account Book.
