Odoo

Avantages

The elegance of the connectivity of the software. It is very obvious the design was incredibly well thought out. Any module being added, 3rd party or otherwise, usually has a seamless integration. The software is simply awesome.

Inconvénients

The support is frankly shameful. They would do far better to publish out-dated documents and say that the software is not supported. Support does not answer questions, they stall, they deflect, and when that fails, they fall back on asking for an "Odoo only" version of the software to test the problem. You cannot operate Odoo without third party software and to attempt to extract third party software and somehow give them access to a version of the software they can test is ridiculous. They should, in those instances, just have the guts to say they're just not going to help you.

Avantages

Odoo adapts to the company needs. When one of the owners of the Organization has a question, the answer can be easily be taken from Odoo, by grouping, filtering and in some other cases, by adding new fields to fill manually or automatically.

Inconvénients

As I jokingly say, sometimes Odoo is in a bad mood (when there is slow Internet connection) and Odoo displays an error or makes a rare behavior. But by refreshing the page, most of the times, it gets solved.

Avantages

1) Opensource and SaaS option
2) Easy to use - Maintained uniformity across modules
3) Availability of Third Party apps
4) OCA community support
5) No other opensource ERP covers Inventory (Product master - ability to handle product variance / Inventory valuation / Landing Cost) and Recruitment functionality like odoo
6) Odoo Enterprise Accounting reporting is a plus
7) Easy to customize or develop new module using Odoo Studio if your an enterprise customer
8) Developing new module even in enterprise will not take much time
9) Partners availability across globe is a plus
10) Having Ecommerce functionality in an ERP is great advantage

Inconvénients

1) Need customization for localization ( Both HRMS - End of service calculation and Taxation)
2) Must to have functionalities are moved from community to enterprise form Odoo version 9 onward till odoo 12
3)Must to have accounting reports moved to Odoo enterprise
4)Not providing incremental update to the existing version is minus
5) Different pricing for different region
6) Document management features could have been better even-though they released few more functionalities in Odoo 12

Avantages

Odoo is an Opensource ERP with a free Community Edition and a paid Enterprise edition. It is packed with features like Accounting, Project Management, Customer Management, Employee & Recruitment Management, Inventory & Warehouse, Sales and Purchase and POS to name a few.
I like the Dashboard where one can get an bird's eye view of the status of any task or activity that needs attention. Plenty of additional modules (called Apps) are also available on the Odoo Store.

Odoo uses Postgresql as database.

It offers plenty of customisation options. Some countries' standard Chart of Accounts are available by default, or you can create your own.

Overall a very useful ERP.

Inconvénients

I'm reviewing the Community Edition: On the downside, it has a relatively big learning curve. Setup and initial configuration is crucial. I would have liked to choose between mySQL and Postgresql as some hosting providers does not offer Postgresql.

Some minor frustrations is the fact that an invoice can only be created after a quotation, then an order. I would've liked to be able to enter an invoice without an quote or order; for example monthly regular contractual invoices. Having said that, depending on how your business work, it might not affect you that much.

Secondly, recording expenses is cumbersome - expenses are recorded either through the employer expense module (which is not always related to an employer, like rent), or through billing. Either way, you need to create a "product or service" for expenses before entering them. Where and how you enter them, also affects your expense reporting.

I would also like to see more reporting options like traditional desktop apps.

Customer support for the Community Edition are limited to the forums and some manuals for older editions.

Avantages

As a former Netsuite and Salesforce partner, our clients demanded more in the form of ease of use, mobility and functionality without breaking the bank. We started off by migrating ourselves off of our Netsuite system. This move simplified all of our daily work lives so much, we brought this solution to our client base. From Professional Services, Manufacturing and Warehouse operations, Odoo was an excellent fit and an extremely good value. The company improves the software almost daily and with thousands of prebuilt apps in their app store, adding major functionality and workflow is simple. Also the open nature of the code makes it the absolute most flexible ERP/CRM/MRP software on the market.
Odoo maintains a few versions Community(Free) and Hosted(Saas) and Enterprise(Self Hosted). We recommend either Hosted or Enterprise(Most Recommended) for business. The Community edition is mostly for developers to have an easy way to learn the basics. The Enterprise edition is packed with additional advanced features necessary for production use, and is supported by Odoo and the Odoo Partner Channel.
Any company in the search for an ERP system should include Odoo in their list.

Inconvénients

Documentation needs improvement. Most documents and answers are not centralized but scattered between Youtube, and Odoo Community and GitHub although they have been building a training portal.
