Jtxn during Creation of RCT			(Dated 10 January 2016)

GLCode	Debit	Credit	Remarks
accReceivable		100	Debtors account
Bank	100		Money going in to bank / cashbook
gst_output		5.66	This GLCode has the amount of output tax collected (for all documents)
gst_output_suspended	5.66		This can be of any name, basically this is to see how much gst was collected for deposit and not invoiced out yet.

Settling of Invoice with RCT

No JTXn created

Filing of both RCT and Invoice			(Dated 2 February 2016)

GLCode	Debit	Credit	Remarks
gst_output	5.66		This amount was charged during the deposit, but reversed to avoid double tax upon settling the invoice.
gst_output_suspended		5.66	Upon filing, this account will be reduced to 0 since related tax invoice has already been created.

Refundable deposit do not have any GST!!
