I need to predict attrition of customers who use product that has fixed time period (1 year) licence. I have monthly feature usage data, for example the product has 5 features f1, f2, f3, f4 and f5, I have the usage frequency of these features at a month level and I have data only for 12 months. If the product is licenced on a monthly basis, I could easily formulate the problem as a time varying covariates survival model. However, yearly subscription has made it hard for to formulate the problem as everyone would be attriting at the end of the year not monthly.

Example Data:

User	month	login_usage	tickets_raised	downloaded_reports	functionality1_usage	functionality2_usage	attritted
Test_user	1	20	2	30	12	12	0
Test_user	2	41	3	23	3	3	0
Test_user	3	32	4	12	4	4	0
Test_user	4	67	5	3	2	5	0
Test_user	5	54	0	4	4	5	0
Test_user	6	8	3	5	6	6	0
Test_user	7	56	6	43	7	7	0
Test_user	8	78	8	6	3	4	0
Test_user	9	54	4	23	4	3	0
Test_user	10	6	3	45	5	2	0
Test_user	11	43	2	43	6	87	0
Test_user	12	12	5	6	7	5	1
