This works:

CREATE TABLE cargo.invoice
(
  id bigserial NOT NULL,
  orderid integer NOT NULL,
  cargoid integer NOT NULL,
  invoiceowner integer NOT NULL,
  invoiceaddress character(250) NOT NULL,
  receiverfname character varying(50) NOT NULL,
  receiverlname character varying(50) NOT NULL,
  receiverphone integer NOT NULL,
  sendingdatetime timestamp without time zone DEFAULT now(),
  distance real NOT NULL,
  weight numeric NOT NULL,
  addedtax numeric NOT NULL DEFAULT 8,
  invoiceamount money DEFAULT 0,
  cargocreateddate date,
  cargoupdateddate timestamp without time zone,
  cargocancelled timestamp without time zone
);

create or replace function cargo.insertinvoice (forderid integer,
                                                fcargoid integer,

                                  12345,
                                  now()::timestamp,
                                  10000.30::real,
                                  1000::numeric,
                                  8::numeric,

                                  now()::timestamp);

As Tom pointed out there were many problems:
- List of parameter not matching the table.
- List of parameters types not matching the list in the function call.
- Returning the id from the function.

Some of the casting may not be mandatory, but it is up to you now to check this.

Hope this helps.
