With SliQ Invoicing, you can choose either to show delivery or carriage charges as a line item on an invoice or to show then in the totals section below the list of items on the invoice. Either way you choose to show carriage/ delivery up can specify the appropriate tax rate, e.g. the VAT rate, to add to the carriage charge.
If you are choosing to add carriage as line item on an invoice, you can also store standard carriage charges in SliQ's product database and easily choose them from a dropdown when editing an invoice.
