GST composition scheme dealer - treatment for client expenses reimbursement

GST composition scheme dealer - treatment for client expenses reimbursement

Hello,

I am new to GST and need your help. I am registered as a composition dealer and attract 6% gst charges.

In bill of supply, there are also expenses done on behalf of client for which I seek reimbursement AT ACTUAL with NO MARKUP. As I understand, this is a PURE AGENT concept in GST and hence does not attract any GST. 

However after raising Bill of Supply, which includes service which attract GST and Reimbursement which should not attract GST, I see that in the TAX sheet that GST is calculated for full value including expenses reimbursement. I have marked expenses as OUT OF SCOPE while recording still it happens. Kindly advise what need to be done.
