Can someone help me with this data flow diagram?

Here is the DFD:

It looks like the customer first makes an enquiry to Marketing and then gets the catalogue, then t he customer makes the payment and gets the invoice, then gets sent the product from the ‘Manafacture’ data source, but why does the customer then send a product order to the ‘Ordering’ one?

Can someone explain this briefly?

    don't need the data diagram. the flow is as follows;

    inquiry to manufacturer

    get catalog

    make selection and order the product

    take delivery

    get sent an invoice

    pay bill if all is well
