Hi
read your specification and I understand that you need add on for odoo.
I Have 2+ years of experience in Odoo version 10.0, 11.0, 12.0,13.0 in Sales, Purchase, Accounting,crm, product,Inventory, warehouse,POS, E-Commerce module.
Have developed and customised a lot of modules in above stated versions
Have done many customizations in reporting in the above version of odoo
Have integrated payment gateway in odoo ecommerce website as well
Have done migrations of odoo modules fin almost every version
So, i am sure i can complete any task allocated to me in odoo.
Thank you
