Create a recurring invoice that will automatically generate new invoices based on specified frequency.
Useful for contracts or services that bill on a regular basis.
Always ask for reccurring configuration, for example:
    - How often to generate invoices (weekly, monthly)
    - Number of units for frequency (e.g. 1 for monthly = every month, 2 = every 2 months)
    - Start date
    - End date
    - End invoice count (optional)
    
Ask for additional information if needed, for example:
    - If the client is not found, ask for the client details and create a new client if necessary.
    - If the invoice number is not provided, ask for it.
    - If the due date is not provided, ask for it.
    - If the payment terms are not provided, ask for it.
    - If the bank details are not provided, ask for it.
