Private Office
Your everyday business tools on one private server. Add a compatible provider API key for AI answers; without one, the rest of Private Office still works.
Pricing
One flat price. Your whole business.
All your day-to-day tools in one place: files, documents, customers and invoicing, on a European server reserved for your organisation. One fixed price, not a separate bill for every app. Private Office starts at €39/mo; Managed EU AI is available as an optional add-on from +€19/mo.
Plans
Start with Private Office. Add Managed EU AI when you need it.
Working on your own? Choose Solo. Have a team? Team brings up to 10 people into one shared workspace at a fixed price. Managed EU AI is available if you do not want to create or manage an API key yourself.

Pricing questions
How many users are included?
Solo includes one named user. Team includes up to 10 named users at a flat price. Eleven or more users require a capacity review and assisted quote so the VM can be sized safely. Restricted Grist and Nextcloud guests do not consume a full team seat.
Monthly or annual — what's the difference?
Both are available on every plan. Annual is billed yearly and works out to a lower monthly rate. You can start monthly and switch later.
Is VAT added on top?
French VAT is currently not charged because ReefOffice operates under the franchise-en-base régime — TVA non applicable, art. 293 B du CGI. The checkout and invoice show the total amount payable; contact us for cross-border invoicing questions.
What if I want to leave?
You export everything with one click and can self-host the exact same open-source stack. There's no proprietary format and no lock-in.
What do 'Managed EU AI' and 'Dedicated' mean?
Managed AI is a separate option, subject to availability and eligibility shown in Billing; a trial is not guaranteed. Dedicated GPU AI remains an assisted waitlist offer. The 30-day Essential trial, when open, uses IONOS in Germany.
Can I try it or see it first?
The Demo page shows the access currently offered: a guided visit or a two-hour self-service session when opening requirements are met.
What if I run out of space?
Every server ships with 300 GB — years of documents for most businesses — and your dashboard shows disk usage and warns you well before it fills. If you do outgrow it, encrypted expansion storage (5 TB and beyond) can be attached to any plan, Solo included. It's encrypted on your server before it leaves, so the storage provider only ever sees ciphertext — the same guarantee as your backups.
What happens if I use up my Managed AI token allowance before the end of the month?
Managed AI runs through a fail-closed monthly cap, so you can never be surprised by an overage bill. A typical solo user consumes roughly 0.5–1.5M tokens a month, while the Essential Solo allowance is 10M — several times a realistic month's load. If you do approach the cap, the dashboard shows your usage and unused allowance carries over into the next month (Essential rolls over up to 2× its allowance), so a heavy month is cushioned rather than cut off. You can upgrade tiers or add your own model key at any time; there is no automatic metered spend beyond your flat plan.
What is a compatible API key?
Private Office accepts a compatible API key. You create it separately with the AI service you choose: a regular ChatGPT, Claude or Le Chat subscription does not replace API access. Its price and handling of submitted text follow that service's terms. Prefer not to configure or monitor a key? Choose Managed AI in Billing and ReefOffice will manage the AI connection for you.
