I remember reading and hearing that the accounting application was not Odoo's strong point.
But what I particularly appreciate about Odoo is the constant work to continuously improve their product. Every year, Odoo releases a new version, each time with lots of improvements.
As a result, if before, Odoo's accounting application was not the most efficient, today, it is probably one of the best accounting tools on the market and for a very competitive price (don't forget that if you only use one application, the license is 100% free!).
As proof, KPMG, one of the largest consulting firms in the world, uses Odoo for its accounting and in 100% standard mode!
Do you think a company like KPMG, which has the means to afford the best, would use Odoo for its accounting if it wasn't a quality tool?
