You have two methods of importing PayPal records. Yodlee (which is the method which appears on the Bank screen for the PayPal account) and the Kashflow PayPal App.
If you enable the Kashflow PayPal App, whilst it can be accessed via the Dashboard and Apps, it also needs to be the link on the Bank -> Paypal import section rather than inviting people to 'Add Import' which is confusing!!
Also the Kashflow PayPal App needs updating to import ALL lines from PayPal, not just the first line of the items on the PayPal invoice and the total. At present even if you receive a PayPal payment for :
1 Widget £10
TOTAL Received £14 (less fees).
The Kashflow App creates an invoice with just:
1 Widget £14
Meaning for proper reconciliation, you have to edit every invoice and add a line just for the shipping. Even worse if a customer purchases 3 or more different items from you at the same time.
According to ClearBooks, this is the main reason people switch from Kashflow to ClearBooks.
