As per Rule 3 of point of taxation rules, 2011
point of taxation' shall be, the time when the invoice for the service issued Provided that where the invoice is not issued within the time period specified in rule 4A of the Service Tax Rules, 1994, the point of taxation shall be date of such completion of provision of the service.
Hence if you are going to raise the invoice within 14 Days of completion of service (in your case it would be 14.01.2016) then no need to pay service tax on provision.
