Hello,
i am a crm systems expert with years of experience in installing and customizing crm systems for the client need. I read your request and think that vtiger would be a perfect solution for your business. You can store client records in different modules, for simple clients, organizations or leads, you can create Invoices, Sales Orders, Purchase Orders and Quotes and from them you can create PDF files that you can send directly to the client. Also vtiger has a Calendar module that can be syncronized with google calendar, in order to show more info. You can create different users in different roles, assign record specifically to some users, and some other not. Also the most important thing, everything can be automatic, from sending notifications via mail or sms, creating records, managing mails, updating fields and any other thing you can think of. I am new to freelancer so i am looking for some good reviews first and the budget is not a problem, we can reach any agreement. Feel free to ask me anything on how i can help you.
Best Regards,
Ardi
