We build Slack automation for companies past $1M in revenue where Slack has quietly become the operations layer - the place where deals get flagged, tickets get triaged, approvals happen, and the whole company finds out something is on fire. The interesting work isn’t a single Workflow Builder workflow. It’s the channel governance, the cross-system notifications that don’t turn into noise, and the custom Slack apps that bring CRM, billing, and project context into the place your team already is.
If you need a Slack reseller to manage licensing, we’re not the right call. If your team is already living in Slack and you want it to actually do work instead of just announce work, that’s exactly what we do.
What we automate with Slack
Each pattern below ships with monitoring and channel hygiene, not just a posted webhook.
- Cross-system notifications that respect the noise budget. Salesforce deal closed → channel post. HubSpot MQL → DM to the right rep. Stripe failed payment → finance channel. The discipline is in what doesn’t get posted - we tune the rules so the channel stays signal-heavy, with thresholds, daily digests for low-priority items, and routing logic that respects who actually needs to see what.
- Approval workflows in Slack. Discount approval, PTO, expense, vendor approval, content review - surfaced as a Slack message with approve/deny buttons, with the decision written back to the system of record (Salesforce, HubSpot, NetSuite, your HRIS). Escalation when the approver doesn’t act in N hours. Audit log on the originating record.
- Internal ops bots. Slash commands that let an ops user look up a customer, kick off a workflow, file an incident, request access, or trigger a manual override - without learning the upstream tool. Backed by your real data, not a wiki page that’s already stale.
- Deal-room and customer-channel automation. Auto-created channels on Closed-Won with the right internal members, customer-facing Slack Connect channels with content templates, and channel archival after N days of inactivity. Channel naming standards enforced by an admin bot.
- Slack Connect governance. External-shared-channel auditing, naming and lifecycle policies, customer-facing message templates, and an admin surface that tells you which Connect channels are stale and which are critical. Without governance, Slack Connect turns into a sprawl problem within a year.
- Workflow Builder for the everyday cases. Onboarding new hires, time-off requests, IT requests, customer feedback forms, on-call handoffs. We use Workflow Builder when it’s the right answer (low-volume, in-Slack-only, no complex logic) and graduate to a custom Slack app when it’s not.
- AI agents living in Slack. Triaging inbound messages in a shared support or sales channel, summarising long threads, generating draft responses for review, and answering FAQs from your knowledge base. See our AI agents development post and our AI in task tracking case studies for the patterns. We’ve also written about how AI reduces Slack message overload.
- Incident management and on-call. Auto-created incident channels on PagerDuty/Opsgenie alerts, post-mortem templates in the channel, action-item tracking back to your project tool, and a real-time status feed for stakeholders.
How we work with Slack
Three layers, and we name which layer each problem sits in.
Layer 1: Workflow Builder and native integrations. When the workflow is low-volume, in-Slack-only, and doesn’t need complex logic, Workflow Builder is the right answer. Same for the native integrations Slack ships with Salesforce, HubSpot, Jira, GitHub, etc. - we use them when they cover the use case, and we don’t over-engineer past them.
Layer 2: custom Slack apps. When the workflow needs slash commands, modals, buttons with payload validation, or background processing, we build a real Slack app. Bolt SDK for the runtime, proper signing-secret verification, scopes scoped down to what the app needs, and deployment to a managed runtime (Cloud Run, Lambda, or a dedicated host). For the orchestration around it we lean on n8n or custom code - see our n8n automation guide and our post on building Slack apps with buttons and file uploads in n8n.
Layer 3: AI agents in Slack. When the workflow is “summarise / classify / answer / draft”, an AI agent is often the right shape - but only if it’s grounded in your real systems, has guardrails, and ships with a human-in-the-loop pattern for the cases it gets wrong. See our AI automation guide.
Discovery is one to two weeks. Most Slack engagements start with a channel audit (most workspaces have 300+ channels, many duplicate or stale) and a notification audit (most have a dozen integrations firing into the wrong channel at the wrong frequency). We scope per system and ship in priority order.
Common integrations
The systems we connect Slack to most often:
- Salesforce - deal-stage notifications, approval flows, deal-room channels, Slack Connect with customers. Walkthrough: Slack and Salesforce integration.
- HubSpot - MQL routing, ticket alerts, deal handoffs, and customer Slack channels for CS. Sibling: HubSpot automation.
- Airtable - base updates as Slack messages, channel-based form submission into a base. Walkthrough: Airtable and Slack integration.
- Asana, ClickUp, Linear, Jira, Monday - task assignment alerts, completion confirmations, comment relay back to the right channel.
- Notion - page mentions, database updates, and weekly digests from a Notion source. Sibling: Notion automation.
- Google Workspace and Microsoft 365 - calendar events into a channel, Drive/SharePoint file shares, Gmail/Outlook reply alerts. Siblings: Google Workspace automation, Microsoft 365 automation.
- Stripe, Chargebee, QuickBooks - payment events, failed-charge alerts, MRR digests, vendor approval flows. Sibling: QuickBooks automation.
- PagerDuty, Opsgenie, Datadog - alert routing into incident channels, status updates, on-call escalation.
- Zendesk, Intercom, Front - ticket alerts, SLA escalations, CSAT digests.
What makes a 2V engagement different from a Slack consultant or shop
Most Slack consultancies do either licensing/admin work or build one-off bots. Practical differences:
- We’re operations-first. Each engagement names the operational outcome - fewer missed approvals, faster incident response, lower channel noise - not a feature list.
- We own the build end-to-end after delivery. Most app shops hand you the bot; we keep it running. The Slack platform changes constantly (scopes, signing-secret rotation, retired APIs), and a Slack app without an owner becomes a liability fast. See our operations automation and customer support automation pillars.
- We work with your existing Workspace owner. They keep ownership of plan, billing, SCIM, and admin policy. We take the automation and integration layer.
- We respect the noise budget. A Slack channel with too many bot posts becomes a channel nobody reads. We tune notification rules with the same rigor we’d tune a paged alert.
- We handle Slack Connect properly. External-shared channels are easy to create and hard to govern. We build the lifecycle and naming policy at the same time as the automation that uses them.
When to hire us vs hire in-house
Hire a full-time IT or platform engineer with Slack-app skills when you have predictable, repeated Slack engineering work - a dozen+ custom apps in production, ongoing scope changes - and at least 30 hours a week of it. Most $1M-$20M companies don’t.
Hire us when:
- You have notification noise in critical channels and nobody’s owned the cleanup.
- You need a custom Slack app for an internal workflow (approvals, ops bot, deal-room) and don’t want a developer on payroll for it.
- Your Slack Connect footprint is sprawling and you need governance.
- You want AI agents in Slack but want them grounded in your real systems, not a generic chatbot.
- Your incident response is happening in DMs because nobody set up the right channels and bots.
Pricing & engagement
We have a $5k project minimum. A typical single-system install - say, the approval workflow with Slack as the UI and Salesforce as the source of truth, including the custom Slack app and the routing logic - runs $15-50k depending on scope. A simple notification cleanup engagement can start at the project minimum. Retainers for ongoing Slack-app operation start at $1k/mo.
We don’t quote off a phone call. The Efficiency Scorecard gets us to a real number - 10 minutes of inputs and you’ll see where Slack is doing operational work that could be cleaner. Use the ROI calculator for a rougher pre-engagement estimate.
FAQ
Do you build with Workflow Builder or custom Slack apps?
Both. Workflow Builder is the right answer for low-volume, in-Slack-only workflows with simple logic. Custom apps are right when the workflow needs slash commands with arguments, modals, background processing, signing-secret-verified webhooks, or external data lookups. We default to Workflow Builder when it covers the case, and we don’t over-engineer past it.
Can you work with our existing Slack admin?
Yes - that’s the default. Your admin keeps plan management, SCIM, security policy, and app approval. We take the automation and integration layer.
How long does a typical Slack project take?
A Workflow Builder cleanup or a single Slack app build is usually 2-5 weeks. A larger ops layer - multiple apps, cross-system notifications, Slack Connect governance - runs 8-16 weeks installed in priority order.
How do you handle Slack app security?
Signing-secret verification on every inbound request, OAuth scopes scoped down to what the app actually uses, secrets stored in a real secrets manager (not env vars in a notebook), and audit logs on privileged actions. We submit apps for review when they need to be installed across multiple workspaces.
Can you build customer-facing Slack apps to be listed on the Slack Marketplace?
We can, with a longer timeline. Marketplace submission has its own review process (security, UX, scope justification) that adds 4-8 weeks. If your goal is internal-only, we skip that and ship faster.
Do you do Slack Connect governance separately from app work?
Yes. A Slack Connect audit and policy engagement can stand alone - channel naming standards, lifecycle policy, customer-channel templates, an admin surface for stale-channel detection. Useful when your Connect footprint has outgrown ad-hoc management.
How do you keep notification noise down?
Threshold rules (don’t post every event, post a daily digest unless something exceeds a threshold), per-channel routing (the right event in the right channel), DM-instead-of-channel for individually-actionable items, and a regular review of which channels people are actually reading. We’ve seen channels with 500+ daily bot posts that turned out to need three.
What if our team is on Microsoft Teams instead?
Same playbook, different runtime. Teams has a comparable platform (Power Automate, Adaptive Cards, Teams apps via Bot Framework) and we work in both. See Microsoft 365 automation.
If Slack has quietly become the operations layer of your business but it’s drowning in noise or missing the automations that would make it useful, the Efficiency Scorecard is the right next step. Ten minutes in, you’ll see where Slack is carrying load it shouldn’t and what an engagement would look like. If your stack also leans on Salesforce, HubSpot, or Microsoft 365, the scorecard maps those too.
