Thanks for the information!
I’ve taken a quick look and I notice you’re adding the word ‘morzine’ at the end of the line. The description field actually only takes the first 35 characters of the top line, so anything longer will be discarded. However, looking through the list, nothing stands out as being cut off because of this limit. Do you have any example invoice numbers that you notice are missing?
One thing you may find easier is project tagging. You can specifically tag invoices to a related project tag and even pull up a profit and loss on each tag individually. There’s more on that here
