All of the leading software providers have cloud-based (i.e. online) solutions which allow me to access your books from anywhere, at any time.

These same systems often allow bank-feeds to be set up, and can enable you to email invoices/photos of receipts directly into the software for me to action for you.

Alternatively, there are many file sharing options which will allow you to securely send over statements, invoices, receipts and any other documents.
