The real cost of running n8n for clients (it isn't hosting)

Search "cost of running n8n for clients" and you'll land on hosting comparisons. Fair enough — here they are. But hosting is the cheapest line in this business, and treating it as the cost is how retainers get underpriced.

What self-hosting actually costs

• One shared box, multiple clients: €4-25/mo total. One operator reported a "4 quid Hetzner box with n8n serving 6 clients for about 7 months"; another ran "£25/mo serving 20 client workflows."
• A dedicated VPS per client: €5-20 × N, so €30-120/mo for a 6-client roster — one operator described running "dedicated VPS per client, sometimes multiple servers."
• Hostinger's one-click n8n: $6.49-25.99/mo, unlimited executions, backups, queue mode included.
• n8n Cloud Starter/Pro: €20/€50/mo — doesn't solve multi-tenancy, so it's rarely what agencies actually run.
• n8n Business (the licensed, self-hosted-for-others option): €667/mo, capped at 6 projects.

Compare that to what gets charged for multi-client platforms: GoHighLevel's agency tiers run $297-497/mo, Zapier's blended ARPU is roughly $350/mo, Activepieces Team is $166/mo (isolation without white-label), Activepieces Embed is $36,000/yr for full white-label, and TaskJuice — a direct competitor — starts at $79/199/399/mo metered on compute-hours.

The cost that never makes it into the quote

Hosting a client's automations costs single-digit euros a month. Bringing that client on costs 2-3 days of your time, and keeping their workflows healthy costs another 1-2 hours every month after that. At a $50/hr effective rate, that's $800-1,200 per client onboarded and $50-100/client/mo ongoing — none of which shows up on a hosting invoice, all of which shows up in your calendar.

The people paying $500-1,500/mo retainers for this aren't buying compute. A top reply in a $75K-agency thread put it plainly:

“These systems break quietly... They're paying for the thing to just work.”

What agencies are actually doing instead

Because nothing purpose-built exists yet, the coping strategies are all hand-rolled: one Docker Compose stack per client, run by an operator managing six of them; a dedicated VPS per client, sometimes several servers per client; six clients sharing a single box with no isolation for seven months straight; and, repeatedly, a notepad with one line per client instance — the same notepad quoted above, now one line short of eight.

What to price into a retainer

• Infra: €5-25/mo per box. Real, but rarely the number that should move your price.
• Onboarding time: 2-3 days, or $800-1,200 at a $50/hr effective rate — bill this explicitly or fold it into a setup fee, don't eat it silently.
• Ongoing ops: 1-2 hrs/mo per client, $50-100/client/mo — the line most retainers underprice because it's diffuse rather than a single invoice.
• Credential and OAuth handling: unsolved tooling-wise as of this writing (community forum thread 303935) — assume you're the fallback when a token expires.

Disclosure: we're building Tenvik, and our own cost structure runs the same way — infrastructure is effectively free because docks run on the customer's own cloud account, and the real cost is the control plane and support. The point generalizes past our product: whatever you run n8n on, price the retainer around the time you're actually spending, not the €20 hosting bill.
