Technical

• Python for server
• Python/GTK+ for desktop client
• Web client in development (Repo: http://hg.tryton.org/sandbox/sao Demo: https://demo.tryton.org:8000(there is some issues with certificates))
• Application to manage user portals connected to erp. http://openlabs.github.io/nereid/
• Forked from OpenERP in 2008 -- Tryton#Origin and history
• Migrations from versions are full supported.

Preliminary evaluation

Positive

• Documented modules
• Modular application, wide range of modules
  • Official modules: http://hg.tryton.org/modules/
  • Comunity modules available on bitbucket, see
    • http://bitbucket.org/trytonspain
    • http://bitbucket.org/zikzakmedia
    • http://bitbucket.org/nantic
    • http://bitbucket.org/pokoli (and others).
    • Also avaiilable on pypy https://pypi.python.org/pypi?%3Aaction=search&term=tryton&submit=search.
• Separated client and server presumably making collaboration easy
• Can create reports -- Tryton#Technical features
• Using fixed point in Accouting. Decimal is used on server layer and numeric on the database layer.

GeneratingReports Evaluation

Positive

• Capable of Trial Balance and Chart of Accounts reports.
• Probably capable of Expense, Income reports with minor, semantic[report templates] development effort.
• Possible to create custom reports

Negative

• Does not seem to support funds, thus it is not possible to generate reports for a specific fund.

Examples

• Generated General Ledger.odt.

Evaluation

Evaluation of Reporting UseCases

• Trial Balance Report: Yes
• Bank Reconciliation Report: Yes
• Chart of Accounts: Yes
• Cash Disbursements Journal: FIXME
• Income Report: FIXME
• Expense Report: FIXME

Evaluation of Reporting UseCases for Fund Accounting

Can each of these reports be generated, confined to a specific temporarily restricted asset type?

Tryton does not support fund accounting as of now.

Evaluation of Fund Accounting UseCases

See above.

Collaborating evaluation

• Simultaneous Editing of Ledger: Yes
• FIXME: Other uses cases need rewrite.

Evaluation of Double-entry Accounting UseCases

• Does the system implement pure double-entry accounting? Yes

Evaluation of TrackingDocumentation UseCases

• Does the system link up to external documentation?

• Does it have a the ability to explore transactions via documentation linkage?

Evaluation of Handling multiple currencies UseCases

• Does it support the concept of a single functional currency, while still permitting multi-currency entries? Yes

Evaluation of draft transaction UseCases

• Does the system allow generally for draft transactions that can be later approved before officially being posted to the books? Yes

Evaluation of WorkFlow UseCases

• Is a specific workflow dictated by the system ?
• Is a the workflow configurable ? It does not seem so.
• Unaccrued Invoice ? It does not seem so.

Evaluation of the Reading and Reporting API

Since tryton uses RPC for client-server communication, it seems very likely that you could fetch any data from the server using the tryton RPC interface. However, this interface might include cruft that may make the API harder to use for simple reading.

Evaluation of the Storage API

See above.

Evaluation of the Community Health

• Is the license both determined as Free Software by FSF and OSI-approved? GPL
• Is the ?license GPL-compatible? Yes
• Does the project require assignment of copyright or a CLA to get code upstreamed? Does not seem like it,
• How many ?active developers/companies contribute to the project? A handful, ranging between 4..11 per month in 2013.
  • If there aren't many, how hard would it be to take over the project if needed?
• Is there good developer documentation? Reasonably, being a Python programmer primarily might make my opinion biased.
• How easy it to engage as a developer with the community? They are friendly and helpful.
