Before I get to the list, one thing. There's no point deploying all ten at once. Not even three. Pick one. Finish it. See if it works. Fix it. Then the next one. Companies that try to automate everything at the same time usually end up automating nothing.

Right. Let's go.

1. Automatic email triage

Cost: 2,000 to 4,500 EUR one-off. Implementation: 2-3 weeks. Savings: 10-25 hours per week.

The most frequently deployed automation. An n8n classifier connected to Gmail API reads every incoming email, assigns a category, and either auto-replies with data from the ERP or forwards it to the right person with a note. At a services company where I did this in March, the team stopped reading roughly three quarters of the inbox.

Trap: people don't trust automated replies for the first couple of weeks and manually check everything anyway, which doubles the workload. You need someone to enforce that they stop. Otherwise you've got automation that works and people who verify its work.

2. Payment reminders

Cost: 1,200 to 2,500 EUR. Implementation: 1-2 weeks. Effect: payments arrive 4-7 days faster on average.

n8n hooked into your invoicing system (Enova, QuickBooks, Xero) checks the list of unpaid invoices daily and sends reminders on a schedule: 3 days before due date, on the due date, 3 days after (tone shifts), 7 days after (firm tone). Each reminder is generated by AI, so it doesn't read like a template. The difference between "your invoice is overdue" and "hey, noticed invoice #423 hasn't been paid yet, everything okay?" is massive for client relationships.

Few automations have such a direct impact on cash flow.

3. Automated ERP reports

Cost: 2,500 to 6,000 EUR. Implementation: 2-4 weeks. Savings: 4-10 hours per week.

If someone in your company spends Monday mornings manually compiling reports, this is your candidate. n8n queries the ERP on Sunday night, generates summaries, and sends them to the right people at 7:30 AM Monday. For the clients I've done this for, the weekly summaries auto-sent to their own customers also generated extra orders as a side effect. The customer sees what they ordered and what's left, and immediately adds more.

4. Web forms to CRM integration

Cost: 1,200 to 3,000 EUR. Implementation: 1-2 weeks.

Someone fills in a form on your website. Instead of an email landing in an inbox and rotting for two days, a webhook sends the data to n8n, which creates a contact in your CRM, assigns an owner, sends a welcome email, and sets a follow-up task for tomorrow.

This is so basic it's almost strange I'm writing about it. But a surprising number of companies still handle website leads by manually copying data from an email into Excel. Not even into a CRM. Into Excel. In 2026.

5. Document classification (invoices, orders)

Cost: 4,500 to 11,000 EUR. Implementation: 4-6 weeks.

Automatic reading of supplier invoices, customer orders, shipping paperwork. The system extracts data from PDFs and scans, feeds it into the ERP. At 100+ documents a month the savings are significant. But heads up: for the first three weeks after deployment, accuracy sits somewhere around 70-80 percent and someone needs to verify. After training on your own documents, it climbs above 90 percent.

6. Automated new client onboarding

Cost: 3,000 to 5,500 EUR. Implementation: 3-4 weeks.

New client signs the contract. The system automatically creates an account in the ERP, sends a welcome email with instructions, creates tasks for the account manager (first contact after 3 days, check-in after 2 weeks), adds to the newsletter. Doesn't sound like much, but at 15 new clients a month it saves roughly 8-10 hours of work scattered across multiple people.

7. Deadline monitoring (contracts, certificates)

Cost: 2,000 to 3,500 EUR. Implementation: 2-3 weeks.

Automated scanning of databases for approaching deadlines: client contract expiry, certificate expiration, equipment inspection, license renewal. The system sends alerts at 30, 14, and 3 days out. Missing an ISO certificate renewal or a domain name expiry costs more than this automation.

8. Knowledge base chatbot on your website

Cost: 3,500 to 8,500 EUR. Implementation: 3-5 weeks.

A chatbot connected to your documentation, FAQ, and policies. Answers customer questions on your site 24/7. Works best when you already have a written knowledge base. If you don't, build the knowledge base first, then the chatbot. A bot without a knowledge base is just decoration that says "transferring you to an agent."

Opinion: most chatbots on business websites are the same widget with five canned answers. Don't do that. If a customer asks the bot something specific and the bot replies "please send us an email," that's worse than having no bot at all.

9. AI-powered social media automation

Cost: 2,000 to 4,500 EUR. Implementation: 2-3 weeks.

This isn't about auto-posting (every tool does that). It's about automatically extracting content from things you're already doing: client meeting transcripts, email replies, case studies. AI turns those into LinkedIn posts, X threads, blog articles. It doesn't replace a content strategy, but it supplements it with material that would never normally make it to publication. One construction company I tested this with got a lead from a post generated from an answer their engineer sent to a client via email. Coincidence. But it shows the potential.

10. First-line voicebot

Cost: 8,500 to 20,000 EUR. Implementation: 6-10 weeks.

The most expensive item on the list, and not for everyone. A voicebot makes sense if you're taking more than 40-50 calls a day and a large chunk of them are repeat questions. At the ISP where I deployed this, the bot handled over half of inbound traffic. But at a company taking 15 calls a day, the implementation cost makes no sense.

And one more thing: a voicebot does not replace a human. It replaces the first line. If someone tells you otherwise, ask them to show a case study with real numbers after at least three months. I haven't seen one yet.

Which to do first

If your company has zero automation, start with email triage and payment reminders. Those two pay back the fastest and touch daily processes. Once those are running, move on to reports and form integration.

Voicebot and document classification are things you do after the first four automations are already working. Not because they're less important, but because they're more expensive and more complex, and without experience from simpler deployments it's easy to misjudge the scope.

I don't know if this list is exhaustive. Probably not. But these are ten things I've watched work with my own eyes, not ten things I read about in a report.
