Odoo is the world's easiest all-in-one management software. It includes hundreds of business apps:
CRM | e-Commerce | Accounting | Inventory | PoS | Project management | MRP | etc.
I like to use electronic signature feature introduced in this page: https://www.odoo.com/page/quote-builder
I've installed all moduled that I guessed might be it. I found some functionalities like up-selling that was mentioned in the same page but no electronic signature. I keep sending myself quotes, sales orders and invoices but I can't sign any of them. What am I missing here?
