A library to parse MT940 files, a bank account statement exchange format used by SWIFT. It returns smart Python collections for statistics and manipulation.

Ledger is a powerful, double-entry accounting system that is accessed from the UNIX command-line. This may put off some users, since there is no flashy UI, but for those who want unparalleled reporting access to their data there are few alternatives.

Ledger uses text files for input. It reads the files and generates reports; there is no other database or stored state. To use Ledger, you create a file of your account names and transactions, run from the command line with some options to specify input and requested reports, and get output. The output is generally plain text, though you could generate a graph or html instead. Ledger is simple in concept, surprisingly rich in ability, and easy to use.

It uses peer-to-peer technology to operate with no central authority: managing transactions and issuing money are carried out collectively by the network. Bitcoin Cash is a descendant of Bitcoin. It became a separate currency from the version supported by Bitcoin Core when the two split on August 1, 2017. Bitcoin Cash and the Bitcoin Core version of Bitcoin share the same transaction history up until the split. This package provides the Bitcoin Cash Node command line client and a client based on Qt.

Electroncash is a lightweight Bitcoin Cash client, based on a client-server protocol. It supports Simple Payment Verification (SPV) and deterministic key generation from a seed. Your secret keys are encrypted and are never sent to other machines/servers. Electroncash does not download the Bitcoin Cash blockchain.

Geierlein is a free Elster client, i.e. an application that sends VAT declarations to Germany's fiscal authorities.

Currently it is *not* possible to send returns that are due annually (especially the income tax return) since the fiscal authority doesn't allow doing that off the ERiC library (which is proprietary however). It's not clear at the moment whether one day it will be possible to do so.

Electrum is a lightweight Bitcoin client, based on a client-server protocol. It supports Simple Payment Verification (SPV) and deterministic key generation from a seed. Your secret keys are encrypted and are never sent to other machines/servers. Electrum does not download the Bitcoin blockchain.
