I'm interested in modifying the CRM system:
1. Allowing the use of the system by different companies, so that the company could register in the system and had its database - without the need to install the system on your own server + added option to manage these companies and collecting royalties for the use of the modules of the system
2. Modification of the system invoice so that the invoice is not paid to be a pro-forma invoices, and paying to change the VAT invoice. Adding the option issue a correcting invoice and invoice financing.
3. Add Mailbox combined with existing ticketing system.
4. Add the option of adding multiple mailboxes ticketing
5. Add the stock module
6. Adding the module to send text messages to remind them of payment dates of invoices (to determine when that text messages are sent, for example: x days before the due date, x days after the due date) Same automatic e-mails. Integration API [login to view URL] and [login to view URL]
7. Other minor modifications.
8. Adding the option settlement commission affiliate program (MLM type)
