Payment and billing frustrations

Co-Founder

For over 50 days I had no access to the service I paid for, was repeatedly handed between teams, and promises of rebates/credits went unfulfilled.

Insufficient support documentation

Managing Director

As soon as I started giving him negative feedback on my initial experience (documentation was COMPLETELY out of date - Support had to send me a totally different workflow to get basic task of connecting bank accounts set up) and the fact that I was concerned what else might be out of date...he flippantly said that their docs are often outdated and that's just how it is....then HUNG UP on me mid-sentence (if line disconnected, I'd assume he'd call me back - but never did).

Some users find that the lack of comprehensive documentation increases the learning curve and makes implementation or customization more difficult.

Frequent bugs and reliability issues

Odoo support didnt show the minimum responsibility regarding this big error and considered it as an inconvenience situation and the only thing they offered is to create a new account and told me to redo the wholework myself again. Since my contract with ADG is paused due to delay in project delivery several times.

I can access this system with my cell phone while sitting at the dentist office waiting. As we continue to expand into various countries and subsequently multiple currency accounts, odoo can manage them all. Since we transitioned away from quickbooks, the audit trail is much cleaner and the auditors can simply go through their process.

Language Instructor

I required something that could provide student contacts, course billing and some minimal sales management without the sophistication of the enterprise package.
