My new suppliers are asking for trade references however I do not yet have any?

If you have not yet signed with any other suppliers you will therefore not have any contact details to use as trade references. 

This is not usually an issue as suppliers often only require trade references if you are applying for credit terms (e.g. asking for your orders to be delivered before paying your invoices).

To complete your application form simply enter, "N/A. No credit required. Pro-forma account application only".

Once you have signed your first few suppliers, you will then be able to use them for future credit account application forms. New suppliers will probably not reach out to your trade references anyway unless you are requesting credit terms.
