timeslips electronic billing add on

SUGGESTED

I am running timeslips 2014.  Have not updated because it works so well.  Boss is getting close to shutting things down in the next year.  I now have been informed that one large client with several matters will only accept Ledes 1998n electronic invoices starting January.  Boss does not want to go to the expense of about 2000.00 to do this.   any suggestions or help please
