Open Sourcing the Accountants

Time:13:30 - 14:15
Day:Wednesday 20 January 2010
Location:Ilott Theatre (Town Hall)
Project: The talk include numerious examples from various projects, but particarly from the Amberdms Billing System.

Love it or hate it, there is no way to escape the need for accounting - all businesses need to handle it and often the task is handled to the local company developers.

While developing the Amberdms Billing System, an AGPL-licensed accounting/billing/time keeping application and experience integrating ISP accounting systems with different packages, Jethro has learned a great deal about accounting software requirements from a developer's perspective.


This talk is ideal for anyone interested in open source replacements to commercial accounting packages, running a business, or needing to develop/integrate their tools with accounting software.

The presentation will clarify best practices for developing and integrating with accounting software, including the following key topics:

* Cursory explanation of the double-entry accounting system and a review of how accounts staff think.

* Overview of various open source accounting packages and how to develop for them and integrate with other applications.

* How to properly handle data accounting for ISP service billing (e.g.: data usage billing) and open source apps to make traffic counting easy.

* Mistakes commonly made by accounting packages that break legislation and make life hard for accounts staff.

* Legislation compliance for accounting software in NZ and how to write compliant software.


The talk will cover various open source software packages such as the Amberdms Billing System and SQL-Ledger to demonstrate examples and implementations of accounting software.

Attendees should have a basic understanding of general programming theory, accounting knowledge isn't a requirement but would be beneficial.
