Can I bulk import invoices to BQE CORE?

Yes. You can import unpaid invoices in bulk to BQE CORE using a CSV file from the Invoice Review screen.
The import option is available in the More menu on the Invoice Review screen. It follows the same CSV import pattern used by other CORE modules such as Time Entries and Expense Entries, including field mapping, mapping templates, a review grid before import, and a sample CSV download. Check CORE Help Center for details.
