  • Leads and sales happen in another tool today, and you want them on the same client record as the invoice.
  • A signed proposal and deposit should start the project on the same record as the lead and the client messages.
  • Clients text and call, and those conversations belong next to the project and invoice.
  • You want automated workflows across leads, proposals, projects, and invoices.
