Lead-to-Client Pipeline with CRM
Monitors your Google Sheet for lead status changes to send booking or proposal emails, append new clients, and calculate delivery duration.

What it does
You get automatic booking or proposal emails sent via Gmail the moment your Google Sheet shows a lead is qualified or awaiting a proposal. New clients are instantly added to your tracking sheet when deals close, and delivery duration metrics update automatically once projects are marked as delivered.
Step by step
- Configure a Google Sheets onEdit trigger to fire only when specific columns like 'Stage' or 'Status' are modified.
- Set up an n8n workflow that listens for the webhook payload and parses the JSON data containing lead details.
- Implement conditional logic nodes in n8n to route execution paths based on the new stage value, such as 'Qualified' versus 'Won'.
- Use a code node with JavaScript or Python to calculate the difference between two timestamp fields for delivery duration metrics.
Where the LLM does the work
- Generate personalized email body templates that adapt tone and content based on whether the lead is awaiting a proposal or has just been qualified.
- Draft dynamic subject lines for Gmail notifications that include specific client names and deal values to increase open rates.
- Create error handling messages in code nodes that provide human-readable explanations when data validation fails during the append process.
Watch out for
Timestamp format mismatches often break calculations, so ensure all date strings are parsed using a consistent library like dayjs before computing differences.
Webhook security is critical for n8n endpoints, so enforce authentication headers or IP whitelisting to prevent unauthorized trigger requests.

The agent brief
Everything your agent needs, including the gotchas. Copy it and go.
You are helping me build the following AI agent workflow. ## Goal Lead-to-Client Pipeline with CRM: Monitors your Google Sheet for lead status changes to send booking or proposal emails, append new clients, and calculate delivery duration. ## Specification - What it does: You get automatic booking or proposal emails sent via Gmail the moment your Google Sheet shows a lead is qualified or awaiting a proposal. New clients are instantly added to your tracking sheet when deals close, and delivery duration metrics update automatically once projects are marked as delivered. - Trigger: Triggered by an event (Event · on Google Sheets edit) - Autonomy: Fully hands-off - Expected setup effort: about an afternoon - Tools/services involved: - Google Sheets: CRM data storage and trigger source - n8n: Workflow orchestration and branching logic - Gmail: Sending automated emails for lead stages - Code: Processing timestamps and calculating delivery duration ## Known pitfalls, handle each one explicitly in your implementation 1. Timestamp format mismatches often break calculations, so ensure all date strings are parsed using a consistent library like dayjs before computing differences. 2. Webhook security is critical for n8n endpoints, so enforce authentication headers or IP whitelisting to prevent unauthorized trigger requests. ## Reference implementation https://n8n.io/workflows/7514 (workflow template) Fetch and inspect this before building. If it matches my stack, adapt it; if not, rebuild the pattern with my tools. ## Process requirements 1. Before building: ask me which of the listed tools I actually use and what my platform is (n8n / Make / code / other). Do not assume. 2. Adapt the pattern to my answers; do not force the reference stack. 3. Address every pitfall above; tell me how you handled each. 4. Provide a test plan I can run before letting this touch real data. 5. Ask before any step that sends messages, modifies data, or spends money.

Frequently asked questions
Can I use a different Spreadsheet than Google Sheets?
Yes. Google Sheets is only the example spreadsheet in this recipe. The same flow works with Airtable, Baserow and Excel. Swap the spreadsheet connection and keep the rest of the setup as written.
Want this running in your business?
This is what I do. I design and build AI agents like this one, and keep them running. If you want it set up for your team instead of doing it yourself, get in touch.
Who it's for
Built for founders and execs who need sales handled without hiring for it.
Freelancers and consultants can run this per-client with no changes beyond the source data.
