# 43 Sunsets

> 43 Sunsets builds small, production-grade automations for real businesses. Every template ships with error handling, idempotency guards, and clear setup notes — because "it runs" and "it's ready" are different things.

43 Sunsets is a one-person company near Chicago that helps Japanese-owned manufacturers in the United States work lighter: it turns the manual, inefficient work left in sales, marketing, corporate planning and customer service into small automated systems, one job at a time, with AI and automation. Its first product is Signal (https://43sunsets.com/signal/), a daily reader of public records (building permits, UCC filings, government subsidies, hiring pages) across five Midwest states, currently offered as a beta to selected users. Earlier templates, agent skills and services live under the Studio page (https://43sunsets.com/studio/).

## Pro pack (Gumroad)

- [Quote-to-Cash Follow-up Pro ($19)](https://43sunsets.gumroad.com/l/quote-to-cash-followup-pro): Two n8n workflows + a fully documented spreadsheet template. Up to five follow-up touches that stop the moment a customer replies to the latest email, automatic invoice rows for won quotes, and polite dunning counted from the due date. Optional AI personalisation — runs 100% without an AI key. 14-day money-back guarantee.

## Free n8n templates (official n8n library)

- [Google Reviews — AI Reply Drafts](https://n8n.io/workflows/16889): Watches Gmail for Google's review alerts and drafts a reply following Google's moderation rules. Nothing is posted automatically — the owner approves every word.
- [Quote Follow-up Sequences](https://n8n.io/workflows/16975): Follow up on quotes at day 3, 7 and 14 with Gmail + Google Sheets. Sequence state lives in the sheet, so re-runs and crashes never double-send.
- [Receipt → Expense Ledger](https://n8n.io/workflows/16983): Reads receipts from an inbox (PDFs and photos, via AI extraction) into a Google Sheets ledger, idempotently, with monthly summaries.
- [Google Review Request Emails](https://n8n.io/workflows/17059): Asks happy customers for a Google review two days after job completion, plus one polite reminder — never more.
- [Starred Emails → Obsidian Notes](https://n8n.io/workflows/17205): Star an email in Gmail — once a day it becomes a clean Markdown note in an Obsidian vault, via a Google Drive synced folder. No plugin, no AI key; an idempotent label means an email is never captured twice.
- [Unanswered Quotes → Weekly Digest](https://n8n.io/workflows/17545): Every Monday morning, emails the owner one digest of every quote still waiting on an answer — sorted by money at risk, grouped into going cold, needs a nudge, and still fresh. A digest log guards re-runs, so the same week is never sent twice.
- [Open Invoices → Monthly Statement](https://n8n.io/workflows/17771): On the 1st of each month, sends each customer one statement listing every open invoice with an ageing summary — instead of separate reminders per invoice. A statement log guards re-runs, so the same customer is never sent twice in a month.

## AI agent skills (Agensi)

- [n8n Production-Readiness Auditor ($12)](https://www.agensi.io/skills/n8n-production-readiness-auditor): Audits an n8n workflow export across 10 categories (error handling, credential hygiene, idempotency, rate limits, webhook security, timeouts, observability, data handling, naming, cost traps) and returns a graded report with exact node-level fixes.
- [API Breaking-Change Detector ($12)](https://www.agensi.io/skills/api-breaking-change-detector): Compares API spec versions and flags breaking changes — removed endpoints, changed types, tightened auth.
- Documentation for both skills: https://43sunsets.com/skills/n8n-production-readiness-auditor/ and https://43sunsets.com/skills/api-breaking-change-detector/

## Tools & guides

- [GEO / AI-Visibility Site Audit (Apify, pay per report)](https://apify.com/43sunsets/ai-visibility-site-audit): Audits how visible a site is to AI assistants — robots.txt evaluated per RFC 9309 for 21 AI crawler tokens, llms.txt, structured data, meta hygiene — with an evidence-based report, a ticket-grade fix plan and a ready-to-edit llms.txt draft.
- [n8n Workflow Production-Readiness Checklist, printable PDF ($3.99, Etsy)](https://the43sunsets.etsy.com): The same 10-point audit as the agent skill, as a 2-page printable PDF with 30 concrete checkboxes and a scoring guide.

## Signal by 43 Sunsets — Midwest capital-investment signals (Japanese-language, free beta)

- [中西部・設備投資検出面 — 建設許可 (Construction-permit signal sheet)](https://43sunsets.com/signal/permits/): Detects manufacturing capital investment across five Midwest states (IL, IN, MI, OH, WI) from public construction-permit and state building-review records — often months before press coverage. Facts are verbatim from public records; AI inferences are always labeled. Filterable by state, industry and investment type, with CSV export. In Japanese, aimed at Japanese manufacturing subsidiaries in the Midwest.
- [データの範囲と鮮度 (Data coverage & freshness)](https://43sunsets.com/signal/freshness/): What each of the four sources (building permits, UCC filings, government subsidies, hiring pages) currently covers and when it was last updated, then the per-municipality status of building-permit collection — last fetch, latest permit date, next scheduled update, collection route (public portal, county assessor, FOIA) — with a county heatmap of coverage and the list of covered counties. Regenerated after the daily 02:00 America/Chicago collection and on every data publish (by 04:00 America/Chicago). In Japanese.
