You can add Shipping Charges, in the footer of the invoice, quote or order. Go to Invoicing - Customer Invoices, click on Create Customer Invoice and start creating your invoice. If you are creating an order or a quote, you can go to Sales Order - Create Order or Quotes - Create Quote.
If the field is inactive (grey) and you are unable to fill in your shipping charge, it is because there is no default account registered under Registry - Chart of Accounts - Default Accounts.
Shipping Charges can also be pre-set as follows:
- If you want all invoices to have a shipping charge, enter the amount to be charged on all invoices under Settings - Purchase Order/Invoicing/Sales Order - Invoice input view. See pictures below.
- If you want a specific customer to have a specific shipping charge you can register it on the customer, under Registry - Customers - (Select customer) - Additional Information.
