Check each vendor's page on the day you buy. These prices move, and a quote from last quarter is already stale.
What renting costs
Renting is a monthly fee per person. Three public prices, for one person, look like this[1][2][3]:
| Plan | Per user per month | 10 people, one year | 10 people, three years |
|---|---|---|---|
| Google Workspace Business Standard | $14 on an annual plan | $1,680 | $5,040 |
| ChatGPT Business, billed annually | $20 | $2,400 | $7,200 |
| ChatGPT Business, billed monthly | $25 | $3,000 | $9,000 |
| Microsoft 365 Copilot | $30, paid yearly | $3,600 | $10,800 |
The arithmetic is the price per user, times 10 people, times 12 months. Google's Business Standard price includes Gemini app access[2]. We saw the Microsoft price in a search snippet, not on the full page, so open that page and confirm it before you put it in a budget[3].
Tax is not in those numbers. From January 1, 2027, California sales and use tax generally applies to digital products[4]. Ask your tax adviser how that lands on the subscriptions you actually pay for. We are not that adviser.
What owning costs
Owning means buying a server and paying someone to set it up. One server people ask us about is the NVIDIA DGX Spark Founders Edition. Tom's Hardware reported that its price rose 18% to $4,699, up from $3,999[5]. It has 128 GB of unified memory and a 240 W external power supply. That 240 W figure is the supply's rating, not a draw we have measured at the wall[6].
The hardware line is not the whole bill. Add these, and leave a line blank when you do not have a price you have checked:
- The install. Kodros's one-week install is $4,950 fixed on client hardware. Includes 1 site, up to 10 users, 1 document collection, 30 days support. 50% deposit.
- A network storage box for the backup copies. We do not have a verified US price to put on that line.
- A UPS, the battery box that keeps the server up through a short power cut. Same problem: no verified US price we are willing to print.
- Power. We have no measured running cost for a week in your office.
- Tax on the hardware and the labor.
Fill in only the prices you have opened and read. Get the rest in writing before you compare the two columns.
The year-one comparison
Take ChatGPT Business billed annually: $2,400 a year for 10 people[1]. The server alone is $4,699[5], which is about two years of that plan before the install, the storage box, the battery and the power. Google Workspace Business Standard at $1,680 a year takes longer still to catch the hardware[2]. On these numbers the owned server does not win on cost in year one. It can look better later only if you keep using it and the local model actually does the jobs you care about.
Local models can be less capable than the hosted ones your staff already tried, and a benchmark screenshot won't tell you how big that gap is on your work. Bring one real job, run it both ways if you can, and write down where the local answer was good enough.
When renting is the better choice
Rent the seats when the job is a chat window for a few people, and you want it this afternoon rather than next week. Rent when you want the vendor to own the outages, and you are fine taking your office out of that job. Rent when the files already live in one place you trust, and a seat can see what it needs without a migration.
A seat will not go find the rest of the company for you. It sees the thread you paste in, or the folder you connect, and that is the whole world it has.
When owning is the better choice
Own the server when the files are scattered across email, drives, phones and apps, and you are tired of guessing which copy is current. Own it when you want a clean exit: if you leave, you keep the hardware, the files and the memory. Own it when you can live with a machine that has to stay on, and with a first year that costs more than the seats.
Seats do not gather that sprawl into one place. Each login sees what you hand it. A server you own can hold the shared files and records, and the model works from them there. Our post on what to gather before a business server lists what the room needs before that box arrives.
If you only want the chat window, rent. If the files are scattered and you want them under your control, own the server. You get the hardware, the export and the exit. The first year still costs more than the seats, and the local model still has to do the job.
Questions to ask before you decide
Sit down with whoever pays the invoices and answer these before you pick.
Where do our files live today, and who else holds a copy?
How many people would use this every week, as opposed to opening it once to try it?
Who fixes it when it breaks on a Tuesday, and how fast do they pick up?
What do we lose if we cancel? Can we export the files and the history?
Do we have a spot with power and a network cable, or are we hoping a closet will do?
The second question has a trap in it. "Everyone might use it" is not a count. Write the names.
Questions
Is owning an AI server cheaper than paying for AI seats?
How much does ChatGPT Business cost for 10 people?
The annual price we used is $20 per user per month, which is $2,400 a year for 10 people. Billed monthly it was $25 per user, or $3,000 a year. Those figures leave out tax[1]. Open the live page before you buy, because this number moves.
What does owning buy that renting does not?
The files sit on hardware you control. You can export them. If you leave Kodros, you keep the hardware, the files and the memory. A seat ends when the subscription ends, and you then find out what the export actually contains.
Do these prices include sales tax?
No. California sales and use tax generally applies to digital products from January 1, 2027[4]. Ask your tax adviser how it applies to the subscriptions and the hardware you are actually buying.

What to do next
Kodros puts private AI on hardware you own: the model, the app and the compute, in your building. Every send, post and payment waits for a person. If you leave, you keep the hardware, the files and the memory.
