Hi Aymangabir,
Sorry, I have never found anything fully satisfactory. You may have a look to Noalyss which is to my knowledge the most advanced tool. It is very flexible but will require significant configuration.
My customers have their own accountant to whom they export as much usable data as possible (general ledger). Accountants usually rely on certified commercial software. You have many export formats for a number of these softwares. In my experience however, the difficulty is not software integration but produce data compatible with the accountant expectations (eg a dedicated product accounting account per VAT rate, use of transfer accounts instead of direct bank accounts, …) so that each case require some adjustments.
I know I am not very helpful with that, I hope you are successful in finding the right system !
Regards,
Marc
