When you create an invoice, you need to select which type of invoice to create. There are four invoice types already available in the invoice system by default: Estimate, Invoice, Quote, and Receipt.
Invoice Types allows you to define the wording of the invoice. You can have as many different invoice types defined in the invoice system as you want, but you can only select one per invoice.
ie. If you wanted the heading of the invoice to say 'Skipping Ropes - Invoice' instead of the default 'Invoice', you can edit the invoice heading field in the relevant invoice type to acheive this result.
To go to the invoice type preferences, click the Invoice Types button under the Settings tab
