Invoice leave date in description blank

[Webroy]

Hi,

 

I invoice my customers after the month . So in Februari i invoice the hosting of January. I understand WHMCS only invoices in advance at this moment.

 

So a solution for me would be to leave the date blank in the product description of the invoice.

 

When you open the invoice you see : Hostingproduct and behind it the date for example (08/02/2015 - 07/03/2015)

 

Is there a way or addon to not show that date on the invoices?

 

Thanks in advance
