MLInvoice, formerly VLLasku, is Web-based invoicing for Finnish companies. Includes support for creating and emailing PDFs and Finvoice electronic invoices. The code is written and commented in English, and invoices can be created in English. Multilanguage support/English UI is introduced in version 1.6.0. Some localization work will probably be required for other than Finnish companies.
N.B. Releases and source code are in a new location starting from version 1.6.0. See the home page for more information.
