Simple app to approve Odoo SO, PO from your iPhone / iPad, it has been tested only on Odoo Community 11, but it should work with newer version also. It requires an additional module on Odoo available on Github (link bellow). Odoo – NS module will add “Waiting for confirmation” Status on sale.order and purchase.order model.
You will be able to customize the module and add any document that needs approval (like Invoices, payment confirmation, etc…)
Long press on document from Odoo – NS iOS app will display PDF.
