Hi Anwar -
There are many ERP's that will provide good high level functionality for end to end processing. However if your requirements are detailed in any one are you should look for a Best of Breed (BoB) solution. For instance my company (Snapfulfil) provides a BoB solution for Warehouse Management (WMS) that is significantly better than what you will find in any ERP solution. Happy to discuss further if you have a WMS requirement you find is not filled by the ERP you choose.
As Kirk said, what you need to be looking for is an ERP. And as a small startup, you need to be looking for a scalable SaaS solution. I wrote an article on the top 5 small to medium-sized business (SMB) ERPs. Aptean is a great manufacturing ERP that may suite your needs just fine. So might Netsuite, which provides an end-to-end, affordable SaaS solution for SMBs.
