We constantly see this error in our logs.
And we are always having to cancel off double bills and making sure eveything is really on there.

I'm not too familiar with code, but is it saying that its the Odoo POS addon thats causing a problem - isn't that made by Odoo itself?

What can we do here? We have just started using Odoo, but this is causing us some major headaches!
