Thank you for posting here in the Community. I can share some information about how to make your invoices GST compliant.
There are specific details required to be on your invoices, such as the company name, address, and GSTIN. To comply, you'll need to customise the sales form template and include the necessary details.
First, enable customer GSTIN in the printed invoice. Here's how:
From the Home screen, click on the Gear Menu.
Beneath the column heading Settings, select the Custom Form Styles tab.
Select Edit > Content
In the right section, click on the pencil icon to open the custom form.
Select the Customer GSTIN checkbox.
Once done, you'll need to enable the HSN/SAC column in the printed invoice. Please follow these steps:
From the Home screen, click on the Gear Menu.
Beneath the column heading Settings, select the Custom Form Styles tab.
Select Edit > Content
Now click on the pencil icon on the right in the second section of the custom form.
Select the Item Code checkbox on the left section. Click Done.
You can make the necessary changes to the custom form to ensure all the details needed are available.
Also, we've added new features to make your GST experience complete. Here's the list:
Place of Supply will now be displayed in your printed invoice and will include the State Name and the State Code.
For the Invoice To and Ship Toaddresses, the printed invoice will now display the state code along with the name of the address.
Invoice in print/preview mode will display the tax summary along with total computation.
