My systems of knowledge is very low. But I want to take you and ask for you to present my suggestion: First I want to congratulate the KDE team that produced KMyMoney and continues to improve it. It is by far the best financial management program I know. After I discovered the kmy Money replaces the controls in spreadsheets and other programs used to manage my personal finances.
But I have a suggestion (however, if this mechanism already exists in KMyMoney, please let me know). The suggestion is: can make a link between payments and purchases for each record that is done with the scanned document and to stay in a specific folder. For example: all purchases that do, are paid by credit card, and the related tax document I is delivered by the seller. I would like to have these scanned documents and linked to the respective amount recorded in the bank account or card account whose control is made unitarily by expenditure made in KMyMoney. I have no idea how this suggestion would be implemented, but it would be useful to identify referred to the expense. Often wish to review the expense and knowing referred to was or how much product as such or purchase. And the link would facilitate my life. Tanks Caio
