Do you have any customers or suppliers who use Xero? Why not connect with them directly? Once you have shared your Xero network Key with them you will be able to receive their invoices straight into your sales and purchases in Xero. This is a great way of communicating with your customers and suppliers.
Using the Xero Network will save you time as the invoices are already set up as draft invoices in Xero. All you and your customers have to do is approve the invoices and then they will appear in the awaiting payment section on Xero.
