Two issues here:-
i) Why can't ALL outstanding invoices for a particular customer be shown immediately to attach receipt against - it's ridiculous having to repeatedly click the "show more" button, especially when there are so many outstanding invoices;
ii) I had my first instance of a receipt covering more than 100 invoices (119 to be precise) but the batch receipt system only allows receipts to be attached against a maximum 100 invoices - why is a maximum required ???
