Sir, 

We turf club are taking employees on contractor payroll. Appointment, attendance, supervision, removal are all within scope of principal employer and we also process payroll and share data. Contractor practically name lending purpose . We send money and they disburse.but they raise Consolidated invoice showing reimbursement at actual plus professional fees.why they are charging gst on total amount. If they split invoices, gst on service charge only. Please guide.
