the issue (after many hours of data extraction to spreadsheets) for me seems to be the STLR excludes any sales receipt when it does not include a taxable line item.  My client sells service and parts, but sometimes only service which isn't taxable.  After cross-checking, I found that was the discrepancy with the numbers.  The taxable totals and tax owed both appear to be correct (so there's *some* good news).

Have you determined what invoices/sales receipts are missing from your STLR?
