I am using a QuickBooks Journal entry and my QuickBooks Sales Tax reports are inaccurate

The QuickBooks Sales Tax reports do not work using the QuickBooks journal entry posting method.  Your Sales Tax Payable account should, however, still have all of the details.

You should be able to check by doing something like the following in QuickBooks:
>Reports>Company Financial>Balance Sheet Standard

1) Double-Click on the balance for Sales Tax Payable (this will bring up the individual posting details)
2) Change the date range to "Last Month"
3). Select Customize
4). Select Filters
5) Scross through the filter options and select Transaction Type
6) Scroll though the Transaction Type options and select Journal Entry
7) Refresh the report and the details should equal the total sales taxes collected last month

 

You can check the equivalent in Shogo under:

>Reports>Sales Totals>Last Month>Refresh

Alternatively, you can change the posting method to a Summary Sales Receipt:

Set "Track Sales Tax in QuickBooks" to "On"

Click "Apply Changes" to save the changes to your account.

Please note, when you change posting methods in Shogo, you will need to remap your account to the appropriate items/accounts. 

You should then see an additional menu item on the right side menu to map to your Sales Tax Item(s).
