How to get your GSTR 1 report from Sleek Bill?
In your Dashboard, from the right hand side menu select GST Reports.
Under the newly opened GST Reports menu select GSTR1. Select the financial period (the month that you need to take a report for) and click on the "Export GSTR1" button.
You will shortly receive an excel format report on your email (the one you used to make your Sleek Bill Online account).
