I am trying to apply ERPNext for business who is buying and selling to farmers/local shops where access to Internet is mostly unavailable. I am expecting the user to sync devices at the local offices where internet is available, and make sale/purchase receipts in the field without any internet usage.
I am currently using the following versions
Frappe Framework: v7.2.14
This offline functionality has been planned in the Manufacturing Module enhancement. The enhancement is still on the drawing board and could be 4-6 months away from being available on ERPNext. We will look forward to your contributions when we get going on that module.
