Hi there. Planning to migrate from Odoo Online to Odoo.sh so that our company can use some custom modules. 

Is it possible to use Odoo.sh in store but use the Odoo phone app at the same time? 

For example, Odoo.sh would be used for salesmen drafting up quotations/invoices, but Odoo mobile will be used by the delivery team to validate and sign off on deliveries. 

Is this possible? Thanks.
