Most small businesses don’t need a custom AI agent or a sprawling tech stack. They need five simple, boring automations that save time, prevent mistakes, and quietly make money while the owner sleeps.
After working with businesses across industries the same five workflow problems keep surfacing. The industries differ. The pain is identical. And the fix is usually more straightforward than anyone expects.
At Sonnenberg Design, we build these systems using a carefully chosen set of modern tools: n8n for workflow orchestration, Claude Code for AI-powered logic, Lovable for client-facing interfaces, Supabase for data, and Firecrawl for web intelligence. Here’s exactly how we apply them.
01 — Speed to lead
Never let a warm lead go cold again
Studies show that responding to a new inquiry within five minutes makes you up to ten times more likely to convert that lead compared to responding thirty minutes later. The average business takes forty-seven hours. By that point, the prospect has already called three competitors.
We build speed-to-lead systems using n8n to watch every inbound channel — web forms, Calendly, missed calls, SMS — and fire an instant, personalized response within seconds of submission. Claude Code handles the intelligent qualification layer, reading the lead’s message and routing them to the right team member with context already attached. All lead data flows into Supabase so nothing gets lost and the team has a clean record of every inquiry.
For a dental clinic spending $5,000/month on ads with a 12% close rate, moving that close rate to 25% means 13 additional patients per month from the exact same spend. That math closes the deal faster than any sales pitch.
02 — Document processing
From inbox to database, without a human touching it
Manual document processing costs between $15–$25 per document, takes around fifteen minutes each, and has an error rate between 5–15%. For an accounting firm processing 200 invoices a week, that’s a full-time employee whose entire job is moving numbers from PDFs into spreadsheets.
We automate this entirely. n8n watches the email inbox (or a shared folder) for incoming invoices, contracts, or forms. Claude Code reads the document, extracts every relevant field — vendor, amount, date, line items — cross-references against a chart of accounts or validation rules, and flags anything unusual. Clean data lands directly in Supabase. The human review step, if one is wanted, takes two minutes instead of fifteen.
The result: processing time drops by roughly 85%, errors fall to near zero, and a good chunk of that full-time salary gets redirected to work that actually grows the business.
“The most profitable automations we’ve ever built had no AI in them at all — just clean logic that moves data from A to B without a human ever touching it.”
03 — Follow-up sequences
80% of sales need five touch points. Most businesses send two.
Someone fills out a form, attends a webinar, or has an initial call. The business follows up once, maybe twice, then moves on. That person just needed one more touch point. Research consistently shows 80% of sales require at least five follow-ups. Most sales teams stop at one or two.
We build automated nurture sequences in n8n that run every time a trigger event fires — a form submission, a webinar attendance, a demo request. Claude Code writes personalized follow-up messages that pull context from each lead’s history in Supabase, so every touchpoint feels specific rather than templated. Firecrawl lets us pull in live context about the lead’s company or industry, adding another layer of relevance. The moment someone replies or books a call, the sequence stops and the sales rep gets notified with the full conversation history.
A B2B consulting firm running monthly webinars with 60 attendees and a 4% conversion rate moved to 10–12% conversion after implementing this system. Same webinar, same content, same spend — they just actually followed up.
04 — Database reactivation
The gold mine that’s already been paid for
Every business that’s been operating for more than a year is sitting on a forgotten database: past customers who churned, trial users who disappeared, leads who went quiet after a promising conversation. These people already know the business. They’ve already shown interest. They’re just collecting dust in a CRM.
We build reactivation workflows that segment these contacts by where they dropped off, then send personalized outreach that references their specific history with the business — not a mass blast, but a message that feels like a real follow-up from someone who remembered them. n8n runs the sequencing, Claude Code handles the personalization logic and qualification, and Supabase holds the contact history that makes the messaging feel genuine. We often use Lovable to give clients a clean dashboard to monitor the campaign in real time without needing to log into multiple tools.
A local gym with 4,000 dormant contacts achieving even a 2–3% reactivation rate brings back 80–130 members. At $50/month with average 8-month retention, that’s $32,000–$48,000 in recovered revenue — from people they already had.
05 — Internal reporting
The one nobody wants to talk about, and nobody wants to live without
Every business has someone spending hours each week compiling information that other people need to make decisions. Sales pipeline numbers, client KPI reports, project status updates, daily order summaries. It’s not hard work — it’s just relentless, manual, and error-prone.
We automate this entirely using n8n to pull data from every tool a business already uses — CRMs, project management tools, email, calendars — and aggregate it in Supabase. Lovable builds a clean, client-facing reporting interface so the team sees what they need where they already look. When relevant, Firecrawl pulls in external market context — competitor pricing, industry benchmarks — and weaves it into the report automatically.
One of the most impactful systems converted daily phone orders into formatted text summaries delivered to a construction crew each morning. It saved 45 minutes a day and eliminated $12,000/month in scheduling errors. The crew didn’t change a single habit. That’s the point: the best automation meets people exactly where they already work.
How we choose where to start
When we begin working with a new client, we ask one question: “If 500 new customers showed up at your business tomorrow, what breaks first?” That answer tells us where the real bottleneck is — and that’s where we start.
Think of your business as a pipe. Money flows through it. If there’s a clog near the beginning, pouring more water in (more ads, more leads, more salespeople) just makes the mess worse. Our job is to remove the clog first. These five automations are the most common ones we find.
We don’t force a solution. We identify the actual constraint, build something that removes it, and make the math obvious before we ever ask for a commitment.
