Are there any conditions under which a company that wants to join will be refused?

The ProZ.com staff reserves the right to refuse business members on a selective basis. 

Companies may not be accepted as business members if

• they have low average Blue Board entries
• there are reports of non-payment on file from ProZ.com translators or interpreters

Moreover, existing business memberships may be revoked due to non-payment reports and low average Blue Board entries.
