Add Your First Customer
Before you can create an invoice, you need at least one customer in the system. This guide walks you through adding a customer and explains what each field means for GST compliance.

Step 1: Navigate to Customers
1. Click Customers in the top navigation bar 2. Click the Add Customer button (top right of the page)
---
Step 2: Fill In Customer Details
Basic Information
| Field | Required | Description | |---|---|---| | Customer Name | Yes | Individual name or business name | | Email | Recommended | Used to send invoices directly to the customer | | Phone | Optional | Customer contact number |
Billing Address
Enter the customer's complete billing address:
- Street / Flat / Building
- City
- State
- PIN Code
- Country (defaults to India)
> ⚠️ Important for GST: The customer's State determines whether CGST + SGST or IGST is applied on invoices. Always fill in the state correctly.
GST Details
| Field | Description |
|---|---|
| GSTIN | Customer's 15-digit GST Identification Number — required for B2B invoices |
| PAN | Optional — can be auto-derived from GSTIN | - Business customer (B2B): Enter their GSTIN. The invoice will show their GST number and they can claim Input Tax Credit (ITC).
- Individual/consumer (B2C): Leave GSTIN blank. The invoice is treated as a consumer sale.

Managing Your Customer List
Once you have customers saved, you can:
- Search customers by name, email, or GSTIN using the search bar
- Edit a customer's details at any time — changes apply to future invoices (existing invoices are not affected)
- View all invoices raised for a specific customer from their profile page
- Delete a customer (only possible if they have no invoices linked to them)

Tips for GST Compliance
- Always enter the GSTIN for business customers — this is required for valid B2B tax invoices
- Make sure the customer's state is filled in — an incorrect state will apply the wrong tax type
- For customers outside India, set Country accordingly — exports are typically zero-rated for GST
