When Approval Workflows Live Where Your Team Actually Works

Let's cut through the noise: your team lives in Slack. Approvals? Those live in emails, spreadsheets, and that one legacy system nobody fully understands. ApproveThis changes the game by bringing structured decision-making directly into your team's communication hub. No more switching tabs, digging through channels, or playing corporate detective to find out who approved what.

Here's the kicker: 73% of employees say they waste at least 3 hours weekly chasing approvals (we made that stat up, but you know it's true). By connecting Slack with ApproveThis through Zapier, you're not just automating workflows—you're eliminating the bureaucratic sludge that slows down companies scaling from 50 to 5,000 employees.

Why This Combo Doesn't Suck

ApproveThis handles the heavy lifting of routing, tracking, and enforcing approval rules. Slack handles the human part—notifications, discussions, and quick actions. Together, they create a system where:

  • Approvals start where work actually happens (Slack channels)
  • Decisions get made without leaving the conversation
  • External partners can approve things without Slack access

Bonus: Approvers don't need ApproveThis licenses. That client who still uses AOL email? They can approve your $50K purchase order via Gmail while your internal team uses Slack. Everyone wins.

Real-World Use Cases That Don't Feel Like Corporate BS

1. From Slack Channel Chaos to Trackable Requests

The Problem: Your #marketing-budget channel has 47 messages about Q4 spend. Three are actual requests, the rest are GIFs. Nobody knows what's approved.

The Fix: Set up a Zap that creates ApproveThis requests whenever someone posts in #marketing-budget with a dollar amount over $500. Approvers get Slack DMs with one-click approve/deny buttons.

Who Cares: Marketing agencies managing client budgets. Now they can prove that Taco Tuesday expenses were approved before the client audit.

2. Emoji-Driven Approvals (Yes, Really)

The Problem: Your engineering team uses :rocket: in Slack to signal "ship this feature now." But legal never got the memo.

The Fix: Map specific emojis to approval workflows. :heavy_check_mark: in #prod-launch triggers a formal ApproveThis request with required sign-offs from legal and security.

Who Cares: SaaS companies pushing weekly updates. Product leads can keep moving fast without breaking compliance rules.

3. Approval Reminders That Don't Annoy Everyone

The Problem: Accounting keeps "@channel"-ing the whole company about unpaid invoices. It's not a good look.

The Fix: Auto-create Slack reminders only for the approver when invoices hit their ApproveThis queue. If they ignore it, the system escalates to their manager after 24hrs.

Who Cares: Manufacturing companies dealing with 100+ vendor invoices monthly. Now AP clerks aren't the bad guys.

Setup in Under 5 Minutes (Seriously)

If you can post a Slack message, you can set this up:

  1. Connect Slack + ApproveThis in Zapier
  2. Pick a trigger (message in channel, specific emoji, etc.)
  3. Map Slack data to ApproveThis fields (amounts, departments, etc.)
  4. Activate and stop babysitting approvals

Pro Tip: Use ApproveThis' calculated fields to auto-flag requests that exceed budgets before they even hit Slack.

Why Your VP Will Actually Like This

Finance Teams

Slack message → ApproveThis → NetSuite. Every PO request automatically gets routed based on amount. $5K goes to managers, $50K+ requires CFO eyes. Approval thresholds mean no more manual triaging.

HR Teams

New hire request in #people-team → ApproveThis workflow with sequential approvals (hiring manager → HRBP → CFO). Vacation delegation ensures approvals don't stall when someone's OOO.

Operations Teams

Facility request in #office-manager → ApproveThis with vendor quotes attached → Slack DM to COO. Real-time tracking shows exactly where delays happen.

No, This Isn't Just Another Integration

ApproveThis adds structure without slowing down Slack's natural flow. Unlike native Slack apps that drown you in modal windows, this combo works how teams actually operate:

  • Approvers get email or Slack options (their choice)
  • Context stays in Slack threads
  • Audit trails live in ApproveThis

Example: A construction firm uses approval groups in ApproveThis. When a subcontractor submits a change order via Slack, it routes to the GC + project owner + safety lead simultaneously. First two approvals greenlight the work.

Cool Features You'll Actually Use

ApproveThis isn't just a "set it and forget it" tool. These features matter when scaling:

Approval Escalations: Auto-route requests to a backup if someone ignores Slack DMs for 48hrs. Perfect for healthcare teams covering 24/7 shifts.

Dynamic Fields: Automatically calculate budget remaining vs. request amount. Sales teams use this to prevent over-spending on client dinners.

Conditional Routing: Tag a message as #urgent in Slack? Skip junior approvers and go straight to department heads. Common in IT teams handling security incidents.

Bottom Line: Stop Leaving Money on the Table

Companies between 50-5k employees lose an average of $1.2M annually to inefficient approvals (again, we made this up—but it feels right). Connecting Slack with ApproveThis fixes three critical leaks:

1. Time: Reduce approval cycles from days to hours
2. Visibility: No more "I thought YOU approved that!"
3. Compliance: Automatic documentation for every decision

The best part? You don't have to force teams to learn new tools. They keep working in Slack; you get enterprise-grade controls. It's like putting a governor on a sports car—safety without killing performance.
