Plain Text Accounting
### accounting
**[accounting](https://en.wikipedia.org/wiki/Accounting)** is tracking the flow of valuable commodities, such as money or time.
It clarifies activity, priorities, obligations, opportunities.
It can **[reduce stress](http://podcastle.org/2009/10/09/pc-miniature-38-accounting-for-dragons)** and even be enjoyable.
**[double-entry bookkeeping](https://en.wikipedia.org/wiki/Double-entry_bookkeeping_system)** is a process for doing this reliably.
For every movement of value (a **[transaction](https://en.wikipedia.org/wiki/Financial_transaction)**), both the source and destination are recorded.
Simple arithmetic invariants help prevent errors.
In traditional double-entry bookkeeping, value at any point in time is tracked in various **[accounts](https://en.wikipedia.org/wiki/Account_(accountancy))**, classified as
**[asset](https://en.wikipedia.org/wiki/Asset)** (owned),
**[liability](https://en.wikipedia.org/wiki/Liability_(financial_accounting))** (owed)
or **[equity](https://en.wikipedia.org/wiki/Equity_(finance))** (invested).
Two more classifications track changes during some period:
**[revenues](https://en.wikipedia.org/wiki/Revenue)** (inflows)
and **[expenses](https://en.wikipedia.org/wiki/Expense)** (outflows).
Transactions consist of
**[debits](https://en.wikipedia.org/wiki/Debits_and_credits)** (increases to asset or expense accounts, or decreases to liability or equity accounts) or
**[credits](https://en.wikipedia.org/wiki/Debits_and_credits)** (decreases to asset or expense accounts, or increases to liability or equity accounts).
### … with text
In 2003, John Wiegley invented Ledger: a plain text data format and command-line reporting tool for efficient double-entry-style accounting.
This idea went viral among software developers and technical folk, and we now have
5+ actively-developed **[Ledger-likes](#ledger-likes)** such as hledger and Beancount,
with 40+ add-on tools and an active community.
This site was created in 2016 to introduce our
tools, documentation, and practices.
Accounting data is valuable;
we want to know that it will be accessible for ever - even without software.
We want to know when it changes, and revision-control it.
We want to search and manipulate it efficiently.
So, we store it as human-readable **[plain](http://ledger-cli.org/3.0/doc/ledger3.html#The-Most-Basic-Entry) [text](http://hledger.org/manual.html#journal)**.
We simplify debits and credits by using
**[signed numbers](http://ledger-cli.org/3.0/doc/ledger3.html#Stating-where-money-goes)** instead -
positive for inflows to an account, negative for outflows from an account.
We define arbitrary
**[account](http://ledger-cli.org/3.0/doc/ledger3.html#Structuring-your-Accounts)
[hierarchy](http://hledger.org/manual.html#account-names)**
to suit our needs.
This scales smoothly from simple to complex scenarios, and from high-level overview to fine detail.
Ledger-likes are, at least in part,
**[command-line](http://ledger-cli.org/3.0/doc/ledger3.html#Basic-Usage) [tools](http://hledger.org/manual.html#usage)**.
This makes them efficient to use and very
**[scriptable](#related-tools)** and flexible.
Ledger-likes also, at their core, tend towards
**[functional operation](https://en.wikipedia.org/wiki/Function_(mathematics))**:
they read the input data without changing it, and output a report.
This simple model makes them easy to understand and rely on.
### questions ?
**who is this for ?**\
Techies, power users, and do-it-yourself-ers, for now.
If you need a complete GUI providing lots of guidance, you may prefer to use something else.
**must I edit text and type cryptic commands ?**\
Not entirely!
"Plain Text Accounting" is a broad description, referring mainly to the data format.
We don't object to additional **[GUIs](#ui-console)**, and they are coming.
**who is using it, and how ?**\
See **[Who's using Ledger?](https://github.com/ledger/ledger/wiki/Who's-using-ledger%3F)** for some stories.
**what are the alternatives ?**\
FOSS tools like GNUCash, Grisbi, KMyMoney.
Proprietary tools like Quicken/Quickbooks, You Need A Budget.
Online tools like Xero, FreeAgent.
(There are **[many](https://en.wikipedia.org/wiki/Comparison_of_accounting_software)**).
**[Spreadsheets](https://backchannel.com/a-spreadsheet-way-of-knowledge-8de60af7146e#.2hr7pi9pb)**.
Paper accounting.
A bookkeeper.
**why is this better than QuickBooks ?**\
Your data remains accessible.
No yearly fees.
Free software you can fix and port.
Cross platform.
Scriptable.
Efficient.
**how do I communicate with my accountant ?**\
Clean up text reports by hand,
print them as PDF,
export CSV reports to a spreadsheet..
**what if my accountant only uses QuickBooks ?**\
You'll need a new accountant,
or a duplicate set of books in QuickBooks,
or to pioneer *ledger -> QuickBooks exporting.
**can I use this to do my taxes ?**\
You can use this to track and report the data needed for tax reporting.
Fill out and submit tax forms with another tool, or by hand.
