How much does AI automation actually cost? A breakdown for small businesses

Every article about AI automation costs does the same thing. Vague ranges. “It depends on your needs.” No actual numbers.

I’m going to give you actual numbers.

These are based on the projects I’ve done and the infrastructure I recommend. Your situation will be different, but at least you’ll have a ballpark instead of marketing fluff.

The three cost buckets

AI automation costs break down into three categories: hardware (or cloud hosting), setup, and ongoing maintenance. I’ll go through each one.

Hardware / hosting: EUR 100-300/month

AI agents need a server to run on. You’ve got two options.

Cloud server (what most clients choose): A dedicated server with a decent GPU runs EUR 100-300/month from providers like Hetzner or OVH. That gets you enough power to run open-source models that handle most business tasks. For European businesses, I recommend EU-based hosting — your data stays in the EU, which keeps GDPR simple.

On-premises (rare, but some clients want it): If you’ve got an old gaming PC or a workstation with a decent NVIDIA GPU (RTX 3090 or better), you can run AI agents on your own hardware. The electricity cost is maybe EUR 30-50/month. But you’re responsible for uptime, updates, and backups. Most small businesses don’t want that headache.

For comparison, a basic Salesforce license runs EUR 25-300/user/month. A decent cloud CRM for a 5-person team costs EUR 500-1,500/month. AI hosting isn’t cheap, but it’s not out of line with other business software.

Setup: EUR 3,500-15,000 (one-time)

This is the part where you pay someone like me to configure everything. What “everything” means varies hugely:

Simple setup (EUR 3,500-5,000): One or two automated workflows. Email triage and response drafting. Calendar management. Basic CRM updates. First workflows running in 1–2 days, full setup within a week. This is where most solo professionals start.

Medium setup (EUR 5,000-10,000): Multiple connected workflows. Invoice processing tied to accounting software. Client onboarding automation. Document generation from templates. Two to three weeks of work.

Complex setup (EUR 10,000-15,000): Full business process automation across multiple departments. Custom integrations with industry-specific software. Training the team. Four to six weeks.

Check my pricing page for current rates. I try to keep it transparent — nobody likes getting a quote that’s 3x what they expected.

Ongoing costs: EUR 300-800/month

After setup, the agent needs babysitting. Not constant babysitting, but regular check-ins. Models need updating. Edge cases pop up. Integrations break when third-party APIs change.

I offer monthly support packages starting at EUR 300/month for basic monitoring and updates. Most clients land in the EUR 400-600 range. That covers:

Monitoring agent performance and fixing issues
Updating models when better versions come out
Adjusting workflows as your business processes evolve
2-4 hours of direct support per month

Some clients don’t want ongoing support. That’s fine — I document everything during setup so you or your IT person can maintain it. But in my experience, about 80% of clients opt for at least a basic support plan for the first six months.

The real question: compared to what?

Costs don’t mean much in isolation. Let’s compare.

Hiring a part-time admin assistant (EUR 1,200-2,000/month): An admin handles 160 hours/month of work. An AI agent handling email, scheduling, and CRM updates typically replaces 60-80 hours of that work. Not a full replacement, but enough that you might not need to hire, or you can redirect the assistant to higher-value tasks.

Annual cost of assistant: EUR 14,400-24,000 Annual cost of AI automation (after setup): EUR 4,800-13,200

Traditional business software (EUR 500-3,000/month): You’re probably already paying for software subscriptions. CRM, project management, accounting, email marketing — it adds up. AI automation doesn’t replace all of that, but it can replace some tools and reduce how much time you spend in the ones you keep.

Doing nothing (EUR 0/month, but…): This is always an option. And sometimes it’s the right one. But if your team spends 20+ hours per week on tasks an agent can handle, that’s EUR 1,500-3,000/month in labor costs going to work that doesn’t need a human brain.

When the math doesn’t work

I’ll be honest: AI automation doesn’t make financial sense for every business.

If you’re a 2-person company with minimal admin overhead, the setup cost alone might take 18 months to recoup. That’s a long payback period for a small business.

If your work is mostly creative or relationship-driven — consulting, therapy, design — there might not be enough automatable work to justify the investment.

And if your existing processes are chaotic and undocumented, you’ll need to organize them before automating. That’s a separate project (and cost) that people don’t account for.

When it works really well

The sweet spot is businesses with 3-15 employees doing a mix of client work and admin. Enough volume that automation saves real hours. Small enough that hiring additional staff is expensive relative to revenue.

Accounting firms. Marketing agencies. Legal practices. Property managers. Insurance brokers. These are the businesses where I’ve seen the clearest ROI — typically 3-6 months to break even on the setup cost, then pure savings after that.

One accounting firm I worked with saved about EUR 2,800/month in labor costs after a EUR 7,500 setup. Payback in under three months. That’s not typical — they had a particularly high volume of repetitive invoice processing. But even the slower payback cases I’ve seen come in under eight months.

What to do next

If you’re trying to figure out whether AI automation makes sense for your business, here’s what I’d suggest: write down the tasks your team does every week that are repetitive and rule-based. Estimate the hours. Multiply by what you’re paying per hour for that labor.

If the number is above EUR 1,500/month, it’s probably worth a conversation. Reach out and I’ll give you an honest assessment. If it doesn’t make sense for you, I’ll tell you that. I’d rather turn away a project that won’t deliver results than set something up that leaves you worse off.
