Basically, QuickBooks calculates the GST for you. You should be adding $13.64, which with 10% GST will give you $15.00:-
INSERT INTO "InvoiceLine" ("TxnID", "InvoiceLineItemRefListID", "InvoiceLineDesc", "InvoiceLineRate", "InvoiceLineAmount", "InvoiceLineTaxCodeRefListID") VALUES ('5CA9-1197764583', '90000-1045537150', '4m Steel Ladder', 1.00000, 13.64, '90000-1045536338')
Where the value of TxnID is the TxnID for the existing invoice. |
