Invoice Management

Learn how to create, manage, and send professional invoices with automatic GST calculations.

Creating Your First Invoice

Step 1: Access Invoice Creation

1. From your dashboard, click the "Create Invoice" button 2. Or navigate to InvoicesCreate New Invoice

Step 2: Select Customer

1. Choose an existing customer from the dropdown 2. Or click "Add New Customer" to create one 3. The customer's GST details will auto-populate

Step 3: Add Invoice Items

Add each item manually, or open Smart Invoice and choose an item from the Catalog. A catalog selection fills its saved description, price, unit, HSN/SAC code, and GST rate once.

For manually entered items:

1. Description: Enter the product or service description 2. HSN/SAC Code: Add the appropriate tax classification code 3. Quantity: Specify the quantity (default: 1) 4. Rate: Enter the unit price 5. Tax Rate: Select GST percentage (5%, 12%, 18%, 28%)

The system will automatically calculate:

  • Line total (Quantity × Rate)
  • Tax amount (based on selected rate)
  • Final amount including taxes

    Step 4: Review and Save the Draft

    1. Check Calculations: Verify all amounts are correct

  • 2. Add Notes: Include any special terms or conditions 3. Set Due Date: Specify payment due date 4. Save Draft: Keep the invoice editable while you review it

    A draft has no permanent invoice number and has not been sent to the customer.

    Step 5: Issue the Invoice

    Open the reviewed draft and click Issue Invoice. The system assigns the next permanent invoice number and locks the invoice's legal details.

    > Issuing does not send or deliver the invoice. It only finalizes the invoice and assigns its number.

    Step 6: Dispatch the Invoice

    After issuing, choose the delivery method that suits you:

    - Email Invoice: Sends the invoice PDF through the configured email service

  • Open WhatsApp: Opens a prepared WhatsApp message for you to send
  • Shared link: Lets the customer open and download the invoice
  • Download PDF: Saves a local copy; customer delivery is not confirmed

    The invoice page displays whether dispatch has not started, was confirmed by email or shared-link download, or remains unconfirmed.
