Most articles about self-hosted AI are written by hobbyists with gaming PCs or by enterprises with data centers. Neither budget looks anything like a ten-person clinic, law office, or contracting shop. Here is the actual bill, line by line, with the assumptions stated so you can re-run the math for your own business.
The hardware: $1,200 to $3,500, once
A sovereign AI server for a small business is not a rack in a cold room. It's a quiet box about the size of a toaster that sits on a shelf in the back office. Our flagship platform is a Start9 server, purpose-built for running your own services, with an interface a non-technical owner can actually use. When the workload calls for more memory, comparable small-form hardware does the job.
What moves the price is mostly memory and whether the box carries a GPU:
| Configuration | Typical price | What it runs well |
|---|---|---|
| Entry (16–32 GB RAM, CPU only) | $1,200–$1,800 | Follow-up, paperwork, triage on smaller models |
| Standard (64 GB RAM, small GPU) | $2,000–$2,800 | Everything above plus reception with fast voice |
| Heavy (96+ GB, larger GPU) | $2,900–$3,500 | Multiple concurrent agents, larger models |
That's the whole hardware story. You own it on delivery. There is no per-seat line, so the eleventh employee costs $0.
The models: $0
This surprises people. The AI models themselves, the part that reads, writes, and talks, cost nothing, because small-business workloads run beautifully on open-weight models (Llama, Qwen, Mistral and their descendants) whose files are published under licenses that allow commercial use. They live on your disk. Nobody can raise the price of a file you already have.
The honest caveat: open models on a small server are not the frontier's equal at every task. For answering phones, chasing invoices, filling intake packets, and sorting an inbox, they are more than equal. Those jobs need reliability and access to your data, not a research-grade intellect.
The build: where the real money is
Software is cheap — making it do your work is not. Connecting agents to your phone system, calendar, invoicing, and forms, teaching them your rules, testing them against your actual documents, and training your staff is skilled labor, whether you buy it or spend your own evenings on it.
- Do-it-yourself: $0 in cash, if you have a technical person with slack time. Budget 60–150 hours of theirs for a first serious setup, and remember whose payroll those hours are on.
- Hiring it done (our fixed-price implementations): $9,000–$28,000 depending on scope, hardware included. A typical two-agent build for a ten-person office lands near the middle: about $14,000.
Running it: the utility bill nobody asks about
A small server drawing 60–150 watts, around the clock, at roughly 11–13¢/kWh (typical Midwest commercial rates) costs $6 to $14 a month in electricity. Call it $20 to be safe with a GPU under regular load. Add nothing for software subscriptions, because there aren't any.
Maintenance: the honest recurring cost
Someone has to apply security patches, test model updates, fix the misses, and keep backups honest. Options, priced plainly:
- Yourself or your IT person: a few hours a month once the system is stable. Free-ish, with the usual risk that "stable" drifts when nobody's watching.
- A care plan like ours: $450–$1,500/month flat depending on response time and how many new workflows you want per month. Cancel with 30 days' notice and the system keeps running. Maintenance is a service, not a leash.
The whole bill, assembled
For a ten-person business buying it done, first three years, middle-of-the-road choices:
| Line | Cost |
|---|---|
| Blueprint (planning engagement, credited to build) | $1,500 → $0 net |
| Implementation, hardware included | $14,000 |
| Care plan, 36 months × $450 | $16,200 |
| Electricity, 36 months × ~$20 | $720 |
| Three-year total | ≈ $30,900 |
About $860 a month, averaged. That's the same neighborhood as stacking two or three cloud AI subscriptions for a ten-person team, except the spend buys an asset, the per-employee price of growth is zero, and the customer data never left your building. (We put the full side-by-side against cloud pricing in a separate article, with its own assumptions shown.)
When this math doesn't work
Plain dealing requires this section. Owning your AI is the wrong answer if your team is two people and a $40/month subscription genuinely covers you. It's wrong if your work involves nothing confidential and never will. And it's wrong if nobody, vendor or staffer, will own maintenance, because an unpatched server is worse than a well-chosen cloud account. A good intake process should tell you no when the answer is no. Ours does, in writing, for $1,500, credited if you build, and kept honest by the fact that you keep the document either way.
