Looking for a Dev who will write a connector between vTiger CRM(MySQL) and Optima ERP(MsSQL) Optima should send inventory to vTiger.
Access to Optima's MSSQL database server is from a Centos VPS (you can change this VPS to a windows one) . vTiger is on a MySQL database on a shared virtual server and has an API https://help.vtiger.com/article/147111249-Rest-API-Manual
You will need to load products with prices and quantities from Optima, and then cyclically update the stocks.
Please send me a quote for the order.
