If this is the case, you have two options:
Option 1: Apply for and wait for your funding to arrive in the bank account before placing an advert on UKCIL.
Option 2: Pay from your own personal funds to cover the £96 UKCIL fee and start using UKCIL to recruit PAs right away. Then reimburse yourself once the advertising funding arrives in your Managed Bank Account (MBA) or Direct Payment Bank Account.
