The Stack

Here is a complete customer support system that costs under $50/month for a startup handling up to 300 messages/month:

1. Message capture: Embeddable widget (included, $0)
2. Intent classification and routing: Pay-per-resolution ($40 to $60/month at volume)
3. Team notifications: Slack (free plan)
4. Bug tracking: GitHub Issues or Linear free tier ($0)
5. Knowledge base: Your existing docs or a simple FAQ page ($0)

Total: roughly $40 to $60/month, scaling with volume.

Setting It Up

Step 1: Add the widget to your site.

Drop one script tag into your HTML. The widget appears as a small chat icon in the corner. When customers click it, they can type their question. No account creation required on their end.

Step 2: Connect Slack for notifications.

Every message that needs human attention gets posted to a Slack channel. Your team sees it, discusses it, and someone handles it. No need for a separate support dashboard if you do not want one (though having one helps as you scale).

Step 3: Set up 5 auto-response rules.

Pick your top 5 question types and write one good auto-response for each. Common ones:

• Password reset: send the reset link
• Pricing: send your pricing page link with a brief summary
• Cancellation: send clear cancellation instructions
• Order tracking: send tracking page link
• General bug: acknowledge and create a GitHub issue

These 5 rules alone will handle 40 to 50% of incoming messages automatically.

Step 4: Set confidence thresholds.

For auto-responses, set the confidence threshold to 85%. This means the system only sends automatic replies when it is very confident about what the customer is asking. Everything else goes to Slack for a human to handle.

Step 5: Add a simple FAQ to your site.

Look at the questions that keep coming in and write brief answers on a single page. Link to it from your widget's welcome message: "Check our FAQ for quick answers, or type your question below."

What This Handles

With this setup, a typical month looks like:

• 300 total messages
• 150 auto-resolved by intent rules (50%)
• 50 deflected by FAQ (customers find answers before messaging)
• 100 handled manually via Slack

Your team spends time on 100 messages instead of 300. At 5 minutes per message, that is 8 hours/month of support work instead of 25 hours.

What This Does Not Handle

Be honest about the limits of a budget setup:

• No phone support (you need a separate tool for that)
• No real-time live chat (messages are asynchronous)
• No knowledge base search (just a static FAQ page)
• Limited analytics (basic dashboard stats only)

For most startups under 500 customers, these limitations do not matter. You do not need a help desk with 50 features. You need a system that answers common questions fast and routes everything else to your team.

Scaling Up Later

When you outgrow this setup (usually around 500+ messages/month or when you hire a dedicated support person), you can add:

• More routing rules for additional intents
• Priority-based escalation for urgent issues
• Integration with your CRM or ticketing system
• Advanced analytics to track trends

The foundation stays the same. You just add layers as needed.
