The Accounting behind Odoo
==========================

This page summarises the way Odoo deals with typical accounts and
transactions.

Double-entry bookkeeping
========================

Odoo automatically creates all the behind-the-scenes journal entries
for each of your accounting transactions: customer invoices, point of
sale order, expenses, inventory moves, etc.

Odoo uses the rules of double-entry bookkeeping system: all journal
entries are automatically balanced (sum of debits = sum of credits).

Accrual and Cash Basis Methods
==============================

Odoo support both accrual and cash basis reporting. This allows you to
report income / expense at the time transactions occur, or when
payment is made or received.

Multi-companies
===============

Odoo allows to manage several companies within the same database. Each
company has its own chart of accounts an rules. You can get
consolidation reports following your consolidation rules.

Users can access several companies but always work in one company at a
time.

Multi-currencies
================

Every transaction is recorded in the default currency of the
company. For transactions occurring in another currency, Odoo stores
both the value in the currency of the company and the value in the
currency of the transaction. Odoo can generate currencies gains and
losses after the reconciliation of the journal items.

Currency rates are updated once a day using a yahoo.com online
web-service.

=======================

Odoo accounting support more than 50 countries. The Odoo core
accounting implement accounting standards that is common to all
countries and specific modules exists per country for the
specificities of the country like the chart of accounts, taxes, or
bank interfaces.

* Anglo-Saxon Accounting (U.S., U.K.,, and other English-speaking
  countries including Ireland, Canada, Australia, and New Zealand)
  where cost of good sold are reported when products are
  sold/delivered.
* European accounting where expenses are accounted at the supplier
  bill.
* Storno accounting (italy) where refund invoices have negative
  credit/debit instead of a reverting the original journal items.

Odoo also have modules to comply with IFRS rules.

Accounts Receivable & Payable
=============================

By default, Odoo uses a single account for all account
receivable entries and one for all accounts payable entries. You can
create separate accounts per customers/suppliers, but you don’t need
to.

As transactions are associated to customers or suppliers, you get
reports to perform analysis per customer/supplier such as the customer
statement, revenues per customers, aged receivable/payables, ...

Wide range of financial reports

reports range from basic accounting reports to advanced management
reports. Odoo's reports include:

* Performance reports (such as Profit and Loss, Budget Variance)

  Receivables)
* Cash reports (such as Bank Summary)
* Detail reports (such as Trial Balance and General Ledger)
* Management reports (such as Budgets, Executive Summary)

Odoo's report engine allows you to customize your own report based on
your own formulae.

Import bank feeds automatically
===============================

Bank reconciliation is a process that matches your bank statement
lines, as supplied by the bank, to your accounting transactions in the
general ledger. Odoo makes bank reconciliation easy by frequently
importing bank statement lines from your bank directly into your Odoo
account. This means you can have a daily view of your cashflow without
having to log into your online banking or wait for your paper bank
statements.

Odoo speeds up bank reconciliation by matching most of your imported
bank statement lines to your accounting transactions. Odoo also
remembers how you've treated other bank statement lines and provides
suggested general ledger transactions.

Calculates the tax you owe your tax authority
=============================================

Odoo totals all your accounting transactions for your tax period and
uses these totals to calculate your tax obligation. You can then check
your sales tax by running Odoo's Tax Report.

Inventory Valuation
===================

Odoo support both periodic (manual) and perpetual (automated)
inventory valuations. The available methods are standard price,
average price, LIFO (for countries allowing it) and FIFO.

Easy retained earnings
======================

Retained earnings is the portion of income retained by your
business. Odoo automatically calculates your current year earnings in
real time so no year-end journal or rollover is required.  This is
calculated by reporting the profit and loss balance to your balance
sheet report automatically.
