[Closed] Expenses - What App do people use for simplicity

So i’m away with work in the Oxford south on an extended secondment for a client company so racking up the expenses left right and centre.

So i need to keep easy track of all of the expenses and costs incurred to make sure i don’t end up out of pocket.

However as I’m employed by a company already they will be doing all the invoicing to the client. But i need to find a way of recording al my expenses and be able to export them for my company to then invoice the client complete with receipts.

What app can i use to record all the expenses and then easily export them out into an easy report?
What do all you contractors use?
I might just have to use both the internal system to get paid and then make my own excel spreadsheet with attached photos/bundle of receipts. Sounds too archaic. There must be a smarter way?
