n8n · AI · Google Sheets · WhatsApp
I rebuild the copy-paste work hiding in your Sheets, inbox, and group chats into n8n workflows you can see, drag, and actually trust.
Same interaction as n8n — pan, zoom, pull the nodes around. Representative graphs for local operators. Live client instances stay private.
Leads, invoices, and follow-ups are tabs named v3_FINAL. One person knows the formulas. When they go on vacation, the process dies.
Review asks, quote nudges, and ‘did you get this?’ texts happen when someone remembers. Money and reputation leak in the gaps.
You need branching, retries, and a human checkpoint — not 14 single-step zaps. n8n is the grown-up version of that mess.
Custom work. A real starting price.
One job, done properly. The messy Sheet process you are tired of doing by hand.
From $500 one-time
Several moving parts: AI classification, branching, retries, and a channel the team already lives in.
Custom quoted
01
We screen-share the Sheet, the inbox, and the ugly exceptions. I write the happy path and the ‘this row is weird’ path before any nodes.
02
Triggers, filters, AI where it earns its keep, notifications you will actually read. Credentials stay in your instance.
03
Bad phone numbers, duplicate leads, API timeouts. Error branches and a Slack/WhatsApp ping so it never fails silently.
04
Loom walkthrough, node notes, and how to pause it. Optional care if you want me watching the executions.
Client work sits under NDA. No live URLs, no brand names. What you see below is the system, the metro, and the numbers — enough to judge the work without putting another owner on blast.

3 weeks to production
Four front desks, one Sheet, and Instagram DMs pasted by hand. Hot leads waited overnight. Nobody knew who had followed up.

The office manager spent Friday on reminders. Duplicate emails, wrong amounts, and a QuickBooks tab that never matched the Sheet.

Producers closed policies and forgot to ask for Google reviews. Renewals lived in a color-coded Sheet that only one person understood.

Outcome
“I was the integration. Form to Sheet to the group chat, every morning. Subhan built the n8n flow, showed me how to drag the nodes, and now emergencies hit my WhatsApp while I’m on a roof. The Sheet is still there — it just updates itself.”
“We did not want another CRM. He automated the Sheet we already had, with error messages I can understand. When a row is weird it pings me instead of failing quietly. That is the whole job.”
“Invoice chasing was a Friday personality test. The workflow is boring in the best way. $500 starter covered the first reminder path; we extended it when we saw it working. No mystery SaaS invoice.”
“He talks like someone who has actually broken a Google Sheets quota at 11pm. Retries, de-dupe, a skip flag for awkward clients. The NDA is why I cannot show you the instance. The graph is why I paid.”
WhatsApp the Sheet screenshot or a Loom of the copy-paste ritual. I will tell you if it is a $500 workflow or a custom system — before anyone writes a node.
