Hi Daniel,
Thank you for trying out erpnext. We are glad that you find it useful.
Right now, it is not possible for you to make erpnext truly multilingual.
ERPNext allows you to change the labels of fields in a form. Hence, you can change the labels to Hungarian Language. Also, it is possible to enter data in Hungarian.
This will make ERPNext partly multilingual. However, messages shown by system like error messages, validation messages, prompts for data entry, navigation pages, etc. will still remain in english.
We suggest that you create a trial account, then try changing the labels of the forms. Then ask your users if they are able to accept the system.
For now, this seems to be the only solution available.
Please give this a try.
Thanks,
Anand Doshi.
Developer, ERPNext.
FYI:
Making erpnext truly multilingual will require a translation module to be setup, which will read translations from a file like:
"Welcome to ERPNext" --> "Üdvözöljük a ERPNext"
However, it will take a considerable time and effort to get it ready. We had started work on it, but the functionality is not mature yet. Due to other commitments, we had to put that work on hold.
Once the translation module gets ready, the translations will involve such above mentioned mappings to be written into a file, i.e. English text to Hungarian Text, for all possible text.
