ledger-autosync
===============

ledger-autosync is a program to pull down transactions from your bank
and create `ledger <http://ledger-cli.org/>`__ transactions for them. It
is designed to only create transactions that are not already present in
your ledger files (that is, deduplicate transactions). This should make
it comparable to some of the automated synchronization features
available in products like GnuCash, Mint, etc. In fact, ledger-autosync
performs OFX import and synchronization better than all the alternatives
I have seen.

Features
--------

-  supports `ledger <http://ledger-cli.org/>`__ 3 and
   `hledger <http://hledger.org/>`__
-  like ledger, ledger-autosync will never modify your files directly
-  interactive banking setup via
   `ofxclient <https://github.com/captin411/ofxclient>`__
-  multiple banks and accounts
-  support for non-US currencies
-  support for 401k and investment accounts

   -  tracks investments by share, not dollar value
   -  support for complex transaction types, including transfers, buys,
      sells, etc.

-  import of downloaded OFX files, for banks not supporting automatic
   download
-  import of downloaded CSV files from Paypal, Amazon and Mint

Platforms
---------

ledger-autosync is developed on Linux with ledger 3; it has been tested
on Windows (although it will run slower) and should run on OS X. It
requires ledger 3 or hledger, but it should run faster with ledger,
because it will not need to start a command to check every transaction.

Quickstart
----------

Installation
~~~~~~~~~~~~

If you are on Debian or Ubuntu, an (older) version of ledger-autosync
should be available for installation. Try:

::

    $ sudo apt-get install ledger-autosync

If you use pip, you can install the latest released version:

::

    $ pip install ledger-autosync

You can also install from source, if you have downloaded the source:

::

    $ python setup.py install

You may need to install the following libraries (on debian/ubuntu):

::

    $ sudo apt-get install libffi-dev libpython-dev libssl-dev libxml2-dev python-pip libxslt-dev

Running
~~~~~~~

Once you have ledger-autosync installed, you can download an OFX file
from your bank and run ledger-autosync against it:

::

    $ ledger-autosync download.ofx

This should print a number of transactions to stdout. If you add these
transactions to your default ledger file (whatever is read when you run
``ledger`` without arguments), you should find that if you run
ledger-autosync again, it should print no transactions. This is because
of the deduplicating feature: only new transactions should be printed
for insertion into your ledger files.

Using the ofx protocol for automatic download
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

ledger-autosync also supports using the OFX protocol to automatically
connect to banks and download data. You can use the ofxclient program
(which should have been installed with ledger-autosync) to set up
banking:

::

    $ ofxclient

When you have added your institution, quit ofxclient.

(At least one user has reported being signed up for a pay service by
setting up OFX direct connect. Although this seems unusual, please be
aware of this.)

Edit the generated ``~/ofxclient.ini`` file. Change the ``description``
field of your accounts to the name used in ledger. Optionally, move the
``~/ofxclient.ini`` file to your ``~/.config`` directory.

Run:

::

    ledger-autosync

This will download a maximum of 90 days previous activity from your
accounts. The output will be in ledger format and printed to stdout. Add
this output to your ledger file. When that is done, you can call:

::

    ledger-autosync

again, and it should print nothing to stdout, because you already have
those transactions in your ledger.

Syncing a file
--------------

Some banks allow users to download OFX files, but do not support
fetching via the OFX protocol. If you have an OFX file, you can convert
to ledger:

::

    ledger-autosync /path/to/file.ofx

This will print unknown transactions in the file to stdout in the same
way as ordinary sync. If the transaction is already in your ledger, it
will be ignored.

How it works
------------

ledger-autosync stores a unique identifier, (for OFX files, this is a
unique ID provided by your institution for each transaction), as
metadata in each transaction. When syncing with your bank, it will check
if the transaction exists by running the ledger or hledger command. If
the transaction exists, it does nothing. If it does not exist, the
transaction is printed to stdout.

Syncing a CSV file
------------------

If you have a CSV file, you may also be able to import it using a recent
(installed via source) version of ledger-autosync. ledger-autosync can
currently process CSV files as provided by Paypal, Amazon, or Mint. You
can process the CSV file as follows:

::

    ledger-autosync /path/to/file.csv -a Assets:Paypal

With Amazon and Paypal CSV files, each row includes a unique identifier,
so ledger-autosync will be able to deduplicate against any previously
imported entries in your ledger files.

With Mint, a unique identifier based on the data in the row is generated
and stored. If future downloads contain identical rows, they will be
deduplicated. This method is probably not as robust as a method based on
unique ids, but Mint does not provide a unique id, and it should be
better than nothing. It is likely to generate false negatives:
transactions that seem new, but are in fact old. It will not generate
false negatives: transactions that are not generated because they seem
old.

If you are a developer, you should fine it easy enough to add a new CSV
format to ledger-autosync. See, for example, the ``MintConverter`` class
in the ``ledgerautosync/converter.py`` file in this repository.

Assertions
----------

If you supply the ``--assertions`` flag, ledger-autosync will also print
out valid ledger assertions based on your bank balances at the time of
the sync. These otherwise empty transactions tell ledger that your
balance *should* be something at a given time, and if not, ledger will
fail with an error.

401k and investment accounts
----------------------------

If you have a 401k account, ledger-autosync can help you to track the
state of it. You will need OFX files (or an OFX protocol connection as
set up by ofxclient) provided by your 401k.

In general, your 401k account will consist of buy transactions,
transfers and reinvestments. The type will be printed in the payee line
after a colon (``:``)

The buy transactions are your contributions to the 401k. These will be
printed as follows:

::

    2016/01/29 401k: buymf
      ; ofxid: 1234
      Assets:Retirement:401k                                 1.12345 FOOBAR @ $123.123456
      Income:Salary                                            -$138.32

This means that you bought (contributed) $138.32 worth of FOOBAR (your
investment fund) at the price of $123.123456. The money to buy the
investment came from your income. In ledger-autosync, the
``Assets:Retirement:401k`` account is the one specified using the
``--account`` command line, or configured in your ``ofxclient.ini``. The
``Income:Salary`` is specified by the ``--unknown-account`` option.

If the transaction is a “transfer” transaction, this usually means
either a fee or a change in your investment option:

::

    2014/06/30 401k: transfer: out
      ; ofxid: 1234
      Assets:Retirement:401k                                -1.61374 FOOBAR @ $123.123456
      Transfer                                                  $198.69

You will need to examine your statements to determine if this was a fee
or a real transfer back into your 401k.

Another type of transaction is a “reinvest” transaction:

::

    2014/06/30 401k: reinvest
      ; ofxid: 1234
      Assets:Retirement:401k                                0.060702 FOOBAR @ $123.123456
      Income:Interest                                            -$7.47

This probably indicates a reinvestment of dividends. ledger-autosync
will print ``Income:Interest`` as the other account.

resync
------

By default, ledger-autosync will process transactions backwards, and
stop when it sees a transaction that is already in ledger. To force it
to process all transactions up to the ``--max`` days back in time
(default: 90), use the ``--resync`` option. This can be useful when
increasing the ``--max`` option. For instance, if you previously
synchronized 90 days and now want to get 180 days of transactions,
ledger-autosync would stop before going back to 180 days without the
``--resync`` option.

Testing
-------

ledger-autosync uses nose for tests. To test, run nosetests in the
project directory. This will test the ledger, hledger and ledger-python
interfaces. To test a single interface, use nosetests -a hledger. To
test the generic code, use nosetests -a generic. To test both, use
nosetests -a generic -a hledger. For some reason nosetests -a '!hledger'
will not work.
