As a personal finance manager, KMyMoney is not intended to scale to the needs of an average business. A small business might find sufficient functionality to use KMyMoney, but features such as accounts-receivable and accounts-payable are not directly supported. However, it would be possible to create client, supplier, document, or other features through plugins.
KMyMoney is not simply a clone of the commercially available personal finance programs. Although many of the features present in KMyMoney can be found in other similar applications, KMyMoney strives to present an individual and unique view of your finances.
