SOFTWARE for LETS
Updated at November 2008
In compiling a brief update to this list, which is still lacking in some details but otherwise links to where further information may be obtained, we are much indebted to Hugh Barnard. This alphabetica list includes the software we know of (marked 'free' that is viable or 'nearly' viable (in some cases, licensing not clear). It also includes some commercial software. Our aim at LETSlink is to make all options known on the basis that different programmes will suit LETS at different stages in their development, starting with the abacus, manual ledgers and Excel spreadsheets! We are now becoming involved in helping LETS directly, because software which is freely given always requires expertise to host and install, and training to use it, and there will be an impact on the way the LETS scheme operates. Anyone wanting to write software please see what projects are already under way and consider joining an existing project rather than re-inventing the wheel. Anyone who knows of software not listed here and/or who wants to have software installed for your scheme please contact
software@letslink.org

OdLETS
This access-based programme holds member records and does Accounts.
At Oswestry & District LETS we use a Microsoft Access database to hold details of all our members, their wants and offers, and all the Oswald transactions. We have made an empty version of the database. It is about 300k ZIPped, and unzips to a 1.6MB database file. It requires Microsoft Access 2.0 or later - users with later versions of Access (e.g. Microsoft Office 95) will automatically be asked if they want to upgrade the database to the latest version when they first load it The database will automatically run a main menu screen, with buttons for all the common tasks. People familiar with Microsoft Access, who want to run ad-hoc reports, or get at the internals of the database should use "Unhide" in the "Window" menu to bring up the main database window.
'free' - To download a free copy of the software go to the website of odLETS, pan down and click on LETS database. No help or support is provided, although I will try to reply to emailed requests for help if I have time - send requests to Nikki Locke: <odlets@trumphurst.com>
OPEN MONEY
php/mysql -tikiwiki based

PyLETS
This web-based programme does Accounts. The LETS administrator has access to cheque entry, and the members can view the results on the LETS website.

PyLETS is written in Python and runs on Unix and Linux. It is a web-based CGI programme, and it uses file locking for data persistence so is very low cost, not needing a relational database backend. Nightly backups to another site are handled by email. In practice it will run on any platform that can do Python CGIs including Windows. Minimum system requirements are whatever will run your web-server, eg Apache - please refer to web server documentation.

PyLETS was first written in 2002. No support is offered. Implementers must be willing to read source code. The current version is 0.4, released May 2003. Development plans include additional columns for historical turnover, implementing year end processing. It is currently being used by Coventry LETS, where Richard Kay is the LETS Accountant. Feedback so far is that "it works much better than the paper-based system it replaces".

'free' - PyLETS is free software written by Richard Kay, operating under GNU Public License available as a free download. It is open to user modification, and if you do modify it the license specifies you must make source code of your changes available to your users. Richard's contact details are: rich@copsewood.net
