Rechargable expenses workflow

One essential thing for me in choosing a cloud accounting system is a simple rechargeable expenses workflow. From taking photos of receipts to invoicing the client and passing on copies of receipts.

I've managed to create an invoice out of relevant rechargeable expenses (after I diligently added the relevant attachments) but when I create the invoice the attachments seem to have disappeared and it wants me to add them again.

Please tell me there is a simple way to record expense and receipt and pass the whole lot over to a client invoice. Otherwise I'm sadly off to FreeAgent...
