Covers most of the organisational needs but need customization as well

Have experience of consulting and over seeing the implementation ( 14 Implementations) of Odoo from version 8 to 11 for the past 4 years.

Pros

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

Cons

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

Extensive ERP for a small to medium sized business.

Having everything in one app is the major benefit to me. I don't have to use different software for Sales and Purchases; for Contacts; fr Projects etc. Another benefit for me is the ability to attach documents to each transaction for tax purposes at the end of the financial year.

Pros

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.

Cons

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.

We liked them so much we Partnered with them

All of my systems and customer data are centralized in one easy to use system

Pros

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.

Cons

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.

Odoo gives you full featured modern open source software to manage a business or any organization.

One of the fastest growing, well rounded, full featured, modern, open source, business, or other organization, management software. * A free community version is available at no cost forever, with about 85% of the features of the paid commercial version. * Very powerful software for organizations of 1 or 2 people, up to hundreds, possibly thousands of employees. * Full accounting including customized international accounting which works in about 100 countries, impressive. * Full website builder lets you drag and drop blocks on the screen to setup your org's website. * Comes with a feature where you can offer live chat support to your customers or audience. * Connects to your bank account in the paid version for automatic verification of account activity. * Manages multiple bank accounts for the various parts of the organization, nice. * Full automation of the employee recruitment, interview, hiring, employment contract, and termination process. * Management of the vehicle fleet or any other set of assets belonging to the organization. * Manufacturing Resource Planning modules are available if you're running this type of organization. * Email app is great and a huge time saver, it becomes a high speed task manager and filter. * Point of sale app is also really cool, from a tablet or phone you can access the minimal set of functions in Odoo needed to check customers out at the point of sale, the great thing is the Point Of Sale can keep running taking payments and tracking which items are sold and their quantity, even when internet access disconnects, then when internet connection comes back, the app will save the completed sales into your Odoo system. * Between 50 and 100 apps. * You can use all the community apps for free.

This totally eliminates the need to connect separate apps made by different companies, or worse, re-enter the same data into multiple different apps, losing tons of time and money.

Pros

No data re-entry. All the apps are connected and share information. Saves so much time and money. Also, you can create your own modules, or hire an outsider to create a module for you, due to the open source nature of the software. Easy to add any of the pre-made apps.

Cons

It can run slow, if you don't take a little time to tune up the server it's running on, and use enough memory, caching, and ideally an ssd. There's a lot of database access happening. Upgrading to the new version is not easy. It would be great if the Odoo company would make upgrading a simple do it yourself automatic task, one click of a button, that would not require human attention for 2 weeks. There's an entire article with more about this on the Odoo site.

Reliable ERP that works for everyone

Increase in efficiency of running my business by 60%

Pros

8 years ago we were actively helping some of our customers implement SAP. I was researching on a better system that is affordable for small and medium business as well. I found OpenERP(Now Odoo) and give it as an R&D project for my team to learn. Seeing the ease and freedom, we implemented it for our business and partnered with Odoo and started providing it as one of our core services to manufacturing/Retail and Wholesale companies in the US and abroad. Main Pros are

Base Opensource - Source Code available
Modular Architecture
Software doesn't dictate how you should run your business - highly customizable
Availability of custom modules for almost every integration
Availability of developers and implementation partners
No Vendor Lock-in and unexpected 300% increase in license costs
Affordable for 5 people business to large corporations
Can be installed on highly secured private dedicated military grade servers for compliance

Cons

Documentation is scattered across different channels, needs to be centralized.
Odoo is still a young company and has a long way to go compared to SAP, but they are working on it.

Improve customer service speed and training manuals and videos

The software has the ability to do anything you want, but the process of customizing needs to be improved. If you are not very computer savvy, there is no way you could use this software or even think of ways to make it better. The customization team needs to take more of an assertive role with helping people figure out what they could do to improve their processes and their software. In addition, because it is so highly customizable, there needs to be top of the line customer service, which there isn't. There needs to be a tech support number to call at all times, because businesses are relying on your software. Right now if you put in a support claim, it takes 34-48 hours to receive a response and then there is so much back and forth, it usually takes 2 weeks to get anything resolved and in the business world, that is not acceptable. The customer service agents should pick up the phone after the first email, if they don't understand what is going on.

Pros

Customizability

Cons

Difficult to learn and difficult to maintain without an IT department.

Odoo is the solution to automate almost all of your business processes.

Speed up internal processes, for example from quotation to delivery or manage your products from stock to webshop and POS. It saves a lot of time and can provide very useful information regarding your business data.

Pros

The reason why we had chosen Odoo is for the combination of applications and being open source. We use practically all modules; sales, CRM, Purchases, projects, webshop/website, POS, HR, repair management, manufacturing, and finance. Most of the competitor ERP software does not provide the webshop/website and POS modules. This point was for us at the end the most important one.

Cons

Because of the great number of applications within Odoo, they are not all at it's very best. But providing feedback, creating your own customisations or even your own modules does help to make the Odoo system more complete and easier to use.
