Why consider leaving OpenConcerto?

OpenConcerto is a recognized French open-source management software developed by ILM Informatique. It is a good tool for simple needs in desktop mode. However, its installed Java architecture and slower evolution mean it no longer meets all the needs of a modern SME.

Java desktop application to install

OpenConcerto is a Java Swing application installed on each workstation. Users must have the Java runtime, updates are done station by station, and the interface is that of a classic desktop application. Dolibarr is a web application accessible from any browser.

No natural mobility

Consulting a quote, validating an invoice or tracking a customer from outside the office is not native on OpenConcerto. You need to go through remote desktop. Dolibarr is natively multi-user web and works on smartphones and tablets.

More restricted community

OpenConcerto has a smaller community than Dolibarr, with fewer third-party modules, less documentation and fewer specialized integrators. Product evolutions largely depend on the ILM Informatique team.

Smaller module ecosystem

Dolibarr offers a community store with over 300 third-party modules covering varied use cases (e-commerce, POS, electronic signature, advanced inventory). OpenConcerto has a more limited catalog.

Slower evolution pace

The OpenConcerto project evolves at a slower pace than Dolibarr. Some expected modern features (e-invoicing with Factur-X and Chorus Pro, complete REST API) are not at the same maturity level.

What you gain by moving to Dolibarr

Moving from OpenConcerto to Dolibarr means staying in the French open-source philosophy while benefiting from a broader ecosystem and a modern web architecture.

Multi-user web application

No more per-station installations and Java runtimes to maintain. Dolibarr is accessible from any browser, with centralized user and rights management.

Native mobility

Responsive interface adapted to mobile and tablet. Your sales reps consult their quotes in meetings, you validate an invoice from home on a Sunday evening if necessary.

Rich module ecosystem

Over 300 community modules on the Dolistore, many of which are free or low cost. You almost always find an existing module to meet a specific need.

Complete REST API

Dolibarr exposes a documented REST API that allows connecting your management to an e-commerce site, POS, payroll tool or any other third-party system. OpenConcerto is more limited on this side.

Active and accessible community

The Dolibarr community is very active in French: forum, documentation, webinars, meetups. You easily find answers to your questions and competent integrators to support you.

How your migration from OpenConcerto works

OpenConcerto uses an accessible PostgreSQL database, which facilitates data extraction. Migration to Dolibarr mainly consists of transforming this data to the Dolibarr model and reproducing business configurations.

1. Audit of your OpenConcerto installation
3 to 5 days
We study your configuration: active modules, settings, data volume, number of stations, external integrations. For a small business, this phase is short (a few days).
2. Dolibarr setup
3 to 5 days
Installation of a Dolibarr instance on Dolicraft hosting or on your side, configuration of the chart of accounts, users, commercial and accounting modules equivalent to your OpenConcerto.
3. PostgreSQL export and transformation
1 to 2 weeks
Export of OpenConcerto tables from PostgreSQL (contacts, items, quotes, invoices, entries), transformation to the Dolibarr model, batch import with consistency checks.
4. Training and user acceptance
1 week
Training of your teams on Dolibarr. Most OpenConcerto users quickly adapt to the web interface, often perceived as nicer than the desktop Swing application.
5. Go-live and support
Ongoing support
Scheduled switch, read-only archival of the OpenConcerto instance, enhanced support during the first weeks. Users no longer need Java on their workstations.

Frequently asked questions

Yes, relatively. OpenConcerto exposes its PostgreSQL database, which facilitates data extraction. The main challenges are chart-of-accounts remapping and business configuration transposition, but nothing blocking for an SME with reasonable volume.

Yes. We extract entries from the OpenConcerto PostgreSQL database and transform them to the Dolibarr accounting model, preserving journals, accounts and counterparts. FEC export is also possible from OpenConcerto.

For a small business or small SME in standard use, migration is generally fast and affordable (4 to 6 weeks). We provide a fixed-price quote after a free initial conversation to frame your need.

In the vast majority of cases, yes. The Dolibarr interface is more modern and often perceived as more intuitive than the OpenConcerto Swing interface. We plan suitable training and close support during the first weeks.

Yes. The Factur-X and Chorus Pro modules are available and allow generating and transmitting compliant electronic invoices. We activate and test them during the integration phase.

Yes. We faithfully recopy your chart of accounts in Dolibarr, with the same account numbers, the same labels and the same analytical structure if you have one.

We keep a readable read-only archive of your OpenConcerto instance during the legal accounting record retention period. You can come back to consult history, but you work on Dolibarr daily.
