ISO app for business

[cpnotebook80]

My friend is looking for an app for his business
He delivers goods to his clients and they pay him or invoice him. Is ther an app that allows him to do that on the spot in his phone . Enter how many items delivered and cost for it and clients name etc. then a report is created at end of month of year showing all transactions ?
Thanks

Set up a free Zoho invoice account to try it out. They have a mobile app that will do what you're describing ("pay him or invoice him"? Did you mean he invoices them?)
