How to Create and Manage Invoices in SiteGiant

Overview

SiteGiant does not allow you to create an invoice directly. Instead, an invoice is generated from an order once it has been paid and updated to Payment Received status.

How to generate an invoice from an order

1. Create the order manually if needed: go to Orders > All Orders > Create Order. Refer to the how to create order manually guide.
2. Once the order is paid, update its status to Payment Received.
3. The system will then generate an invoice number for that order.
4. You can send the invoice to the customer from Orders > All Orders > click the order > ... > Send Invoice.

Manually generating an invoice number (Seller Centre orders)

For orders placed via the Seller Centre, the system does not auto-generate an invoice number (unless through Order Processing > Arrange Shipment). To generate one manually:

1. Go to Orders > All Orders.
2. Click and open the order.
3. Click Generate Invoice No.

Invoice format and prefix settings

The invoice format (prefix and running number) applies across all sales channels — it is not possible to set a different invoice format per channel (e.g. separate prefix for Shopee, Lazada, TikTok, POS).

To configure the invoice format:

• Go to Settings > General > Standards and Formats > Invoice Prefix & Invoice Running Number Size

To enable or disable automatic invoice generation:

• Go to Settings > General > Standards and Formats > Auto Generate Invoice

Changing the invoice logo

To change the logo that appears on your invoice:

• Go to Settings > General > Invoice
