Are you in need of sending or receiving BEAst messages (call off, dispatch advice, invoice et al.) without having any own system support you should choose 'Manual user'. You will receive logon to BEAst Portal which will be your supporting system.
If you have system support and wish to communicate with BEAst Portal users you should choose 'Integrated user'. This option permits corporate group structure, possibility to register multiple companies under the same corporate group, without extra cost. No logon to BEAst Portal will be received.
NOTE! If you only need to send invoices you should not register here but choose Invoice Portal in the previous view
