Yesterday I shared an n8n invoice follow-up agent that actually works. Today I'm sharing the full set — the 5 automations that recover revenue, save time, and don't require a single line of code.
The uncomfortable truth: I've built 30+ AI products. Made closer to $0 than I'd like to admit. The flashier the automation, the worse it performs for small businesses.
The boring ones? They're the ones that actually move the needle.
Here are the 5, with enough detail to build each one this weekend.
1. Invoice Follow-Up Sequence
What it does: Monitors unpaid invoices, sends timed follow-ups at Day 3, Day 7, Day 14.
Revenue impact: 5-10% of previously lost revenue recovered.
n8n nodes: Cron → Gmail Search → AI Classify → Filter → AI Draft → Save Draft → Google Sheets
I covered the full JSON in yesterday's post, so I won't repeat it here. The key insight: a single follow-up email gets 30% of overdue invoices paid within 48 hours. Two follow-ups gets 60%.
Cost: ~$3/month for 20 invoices.
2. Client Onboarding Automation
What it does: Sends a timed email sequence when a new client signs. Collects intake info via form, updates CRM, assigns to the right team member.
Time saved: 3-5 hours/week on manual onboarding.
n8n nodes:
Webhook (form submission) → Set Variables →
IF client_type == "new" →
Send Email (welcome) → Wait 2 days → Send Email (team intro) →
Wait 5 days → Send Email (check-in)
ELSE →
Send Email (returning client welcome)
→ Google Sheets (log) → Slack notification
The prompt for the welcome email:
Write a warm, professional welcome email for a new client.
Business: [YOUR BUSINESS]
Service: [SERVICE TYPE]
Client name: [CLIENT NAME]
Include: what to expect in week 1, who their point of contact is,
and a clear next step. Keep it under 200 words.
Setup time: 2 hours. Payoff: Every new client gets consistent onboarding, and you stop answering the same 10 questions manually.
3. Review Request Automation
What it does: 7-14 days after project completion, sends a review request with a direct link to your Google Business profile.
Revenue impact: Businesses with 4+ stars get 28% more revenue than those with 3 stars (Harvard Business School study). Most small businesses just... never ask.
n8n nodes:
Cron (daily, 9am) → Google Sheets (completed projects, 7+ days ago, no review sent) →
For Each Row →
Send Email (review request with direct link) →
Wait 3 days →
IF no review → Send Email (gentle reminder) →
Update Sheet (review requested = TRUE)
The review request email:
Hi [CLIENT NAME],
[PROJECT] wrapped up last week — hope everything's running smoothly.
If you had a good experience, would you mind leaving a quick review?
It takes about 30 seconds and helps other [INDUSTRY] businesses find us.
[DIRECT GOOGLE REVIEW LINK]
Thanks for working with us!
[YOUR NAME]
Critical detail: Include the direct review link. Every extra click cuts response rate by 50%.
4. Proposal Generator
What it does: Takes a project brief and generates a structured proposal with scope, pricing tiers, and terms.
Time saved: 4-6 hours/week on proposal writing. Close rate improves ~20% with better-structured proposals.
n8n nodes:
Webhook (form or Slack command) →
AI (generate proposal) →
Google Docs (create document) →
Send Email (to client) →
Slack notification (proposal sent)
The prompt:
Create a project proposal with 3 pricing tiers (Good/Better/Best).
For each tier: what's included, price, and a 1-line value statement.
Make the middle tier the most attractive.
Service type: [SERVICE]
Client description: [2-3 sentences about the client]
Their problem: [1-2 sentences]
Budget range: $[LOW]-$[HIGH]
Include: objectives, deliverables, timeline, exclusions, and terms.
Keep the total proposal under 800 words. Professional but not stiff.
Why this works: Structured proposals with 3 tiers consistently outperform single-price quotes. The middle tier becomes the obvious choice.
5. Weekly Report Assembly
What it does: Pulls data from your project management tool and CRM, generates a written summary, and emails it to stakeholders every Monday at 8am.
Time saved: 5-8 hours/week. (This was the biggest time-sink for every business I looked at.)
n8n nodes:
Cron (Monday, 8am) →
HTTP Request (pull from project management API) →
HTTP Request (pull from CRM) →
AI (generate summary) →
Google Docs (save report) →
Send Email (to stakeholders)
The summary prompt:
Analyze this week's business data and produce a report with:
1. What We Completed (3-5 bullets)
2. What's In Progress (3-5 bullets)
3. Blockers and Risks (be honest)
4. Next Week's Priorities (3-5 items)
5. One action item I should focus on this week
Data:

Be direct. Skip the obvious. Highlight what needs attention.
The Math
These 5 automations together:
| Automation | Time Saved | Revenue Impact | Setup Time |
|---|---|---|---|
| Invoice Follow-Up | 3-4 hrs/week | +5-10% collections | 2 hours |
| Client Onboarding | 3-5 hrs/week | Faster activation | 2 hours |
| Review Requests | 0.5 hrs/week | +2-4x reviews | 1 hour |
| Proposal Generator | 4-6 hrs/week | +20% close rate | 3 hours |
| Report Assembly | 5-8 hrs/week | Reclaimed time | 4 hours |
Total: 15-25 hours/week saved, 5-15% revenue recovered. Setup: 12 hours total.
What These All Have in Common
They're boring. Nobody pitches "automated invoice follow-ups" at a conference. But they're the automations that businesses can't afford to turn off.
They replace things humans forget to do. Following up on invoices. Asking for reviews. Sending onboarding emails. These are easy, important, and consistently dropped.
They cost almost nothing to run. Zapier Free handles 100 tasks/month. n8n is self-hosted and unlimited. Gmail is free. Google Sheets is free.
They compound. Each week you run them, they save more time than the week before — because you'd otherwise be falling further behind.
Getting Started
Pick ONE automation from this list. Set it up this weekend. Run it for 2 weeks. Measure the impact. Then add the next one.
If you want the full step-by-step guides for all 5 (with exact prompts, n8n workflow JSONs, and a Quick-Start Checklist), I've put them together in The Boring Automation Pack — $15 CAD, instant download.
Or grab the free AI Automation Cheat Sheet for 10 quick-win prompts.
Honest disclaimer: I'm building these tools and sharing what I'm learning. The Boring Automation Pack is paid. The cheat sheet is free. The n8n workflow JSON from yesterday's post is free. Take what's useful, skip what's not.
The boring automations are the ones that actually pay for themselves. Start there.
