Hi Laura,
In the tax table you set up in Adagio Inventory, do you have the option for 'Include Tax in Cost' selected? If you don't, then there is a place to enter in the Tax GL account for the jurisdiction. When Day End is run in Inventory, this tax account will be debited (and the credit offset goes to AP clearing). The Tax Summary and Tax Tracking reports in Inventory will have this information.
When the invoice is retrieved into AP, indeed the full amount (item plus tax) is going to the AP clearing account, because the tax is already dealt with in IC. AP will not record taxes generated from IC.
If you have the 'Include tax in cost' option enabled in the IC tax table, then instead of a tax GL account getting the debit, it goes instead to the Inventory GL account.
So you don't have to manually deal with GST, as IC does this.
