Can I create transactions dated before July 1st, 2017?

Yes, Zoho Books allows you to create transactions dated before July 1st, 2017. For example if you want to create an invoice,

• Go to the Invoices module under the Sales module.
• Click the dropdown next to the +New button and select New Invoice (Pre GST).
• This will navigate you to the pre GST invoice creation page.

Note: The steps are same across all transactions. The pre GST transactions will not be pushed to GSTN.
