Table value parameters Question

Question

I would like to use a table valued parameter to create an invoice. It will insert into the invoice header data table the header and then it will insert the invoice detail all with different tables. The problem is that until now I was doing this using 2 separate
procedures
1. insert into invoice header
2. insert into invoice detail - this was done with a foreach loop 
foreach row in the invoice insert into invoice detail and it was also adjusting the inventory like so:
USE [Trial]
GO
/****** Object:  StoredProcedure [dbo].[ARD_Insert]    Script Date: 02/25/2014 15:23:22 ******/
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO

ALTER PROCEDURE [dbo].[ARD_Insert]
-- Add the parameters for the stored procedure here
@InvoiceARD int,
@Item int,
@Description nvarchar(50),
@Qty int,
@Price decimal(10,2), 
@TempWOID nvarchar(5),
@InventoryQuantityAddSubtract int 
AS
BEGIN
-- SET NOCOUNT ON added to prevent extra result sets from
-- interfering with SELECT statements.
SET NOCOUNT ON;
    -- Insert statements for procedure here
       --BEGIN TRAN
    INSERT INTO ARD(INVOICE,ITEM,[DESC],QTY,PRICE,TEMPWOID)
    VALUES(@InvoiceARD, @Item, @Description, @Qty, @Price, @TempWOID)
    DECLARE @Type nvarchar(3)
    SET @Type = (SELECT TYPE FROM INV WHERE ITEM = @Item)
    IF(@InventoryQuantityAddSubtract = 0) --Add
    BEGIN
    EXEC InventoryQuantityAdd_Update @Type,@Qty,@Item
    END
    ELSE IF(@InventoryQuantityAddSubtract = 1)--Subtract
    BEGIN
    EXEC InventoryQuantitySubtract_Update @Type,@Qty,@Item
    END
    --COMMIT TRAN
END
how would I be able to do this using table valued parameters

This is the iventoryquantity stored procedure
USE [Trial]
GO
/****** Object:  StoredProcedure [dbo].[InventoryQuantityAdd_Update]    Script Date: 02/25/2014 15:43:40 ******/
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO

-- =============================================
ALTER PROCEDURE [dbo].[InventoryQuantityAdd_Update] 
-- Add the parameters for the stored procedure here
@Type nvarchar(3),
@Qty int,
@Item int
AS
BEGIN
-- SET NOCOUNT ON added to prevent extra result sets from
-- interfering with SELECT statements.
SET NOCOUNT ON;
    -- Insert statements for procedure here
   UPDATE INV SET ONHAND = ONHAND + @Qty,STAMPED = CASE WHEN @Type = 'CIG' THEN STAMPED + @Qty ELSE 0 END, 
LASTDATE = CONVERT(DATE, GETDATE()) WHERE ITEM = @Item
END
