Notify Slack when QuickBooks invoices become overdue

Slack replaces your company's internal email with organized group chats called channels. You create a channel for each project, team, or topic — so conversations stay focused and easy to find. Your team can also share files, hop on quick audio calls (called Huddles), and connect with outside partners through Slack Connect. For a small business, Slack keeps everyone on the same page without the clutter of long email threads. Built-in tools like Canvas (shared documents), Lists (simple task tracking), and Workflow Builder (no-code automation) mean you can manage lightweight projects without paying for extra apps. And with 2,600+ integrations, Slack connects to nearly every tool your business already uses. Slack now includes AI features on every plan — even the free one. The AI can summarize channels you missed, draft messages, answer questions about your company's conversations, and recap your day. It's like having an assistant that reads every message so you don't have to.
