We use AccuLynx as our CRM software along with organizing and handling all of our production i.e. material orders, labor orders, communication with labor crews, tracking job profitability, and invoicing. This software allows us to handle all aspects of our company, and it syncs with QuickBooks. The whole organization is able to use the software, and it allows us to communicate with each other as well. If you are a home exterior company, this is the best software to use! All your outside sales representatives can access everything via an app, subcontractors, vendors, accounting/finance, reception, etc. It brings everyone together and basically everything can be done on this, except for your accounting reports so you do need an accounting software. If you use QuickBooks it does integrate with this, which is amazing.
