Contracts Billing
If the contract is running from Jan 09 to Dec 09 and the invoice durarion is every 4 months I would have 3 invoices
the problem comes in when I add a new line say in FEB I need the first invoice to run from FEB to APR(3 months) an then the remaining invoices should follow the rest of the Contract (MAY,JUN,JUL.AUG and SEP,OCT,NOV,DEC)
Many Thanks
