§02Manifesto

A suite, not a platform.

Platforms capture you. Suites compose. ark is a suite — each tool stays autonomous, and the whole composes into a coherent system when you decide to wire it together.

§01

Independent products

Each app has its own release cycle, pricing and domain. You pick what you actually need — not the whole suite by default.

§02

Connection by consent

Apps only talk to each other once you connect them. No forced sharing, no data moving behind your back.

§03

Sovereign hosting

Everything runs on Infomaniak in Geneva. No US cloud, no third-party trackers, no transfer out of Switzerland without your consent.

§04

Handcrafted

No generic SaaS templates. Every product is built for a specific trade, with Swiss vocabulary and workflows.

§03Shared foundation

What you get everywhere, always.

One foundation for the whole suite — you get all of this, whichever product you use.

Hosted in Switzerland

Your data lives in Geneva, in certified data centres powered by renewable energy.

Geneva

One single login

Sign in once and reach every app in the suite — no juggling ten passwords.

SSO included

Apps that talk to each other

The apps exchange your data automatically and securely. No more copy-paste between tools.

No re-entry

AI that assists, not replaces

Categorisation, extraction, document reading. AI prepares the work, you keep the decision.

AI assistant

Built for Swiss rules

Swiss VAT, QR-bill, accounting exports, tax returns: everything is built for Switzerland.

Swiss-ready

Independent

Each app has its own pricing, site and rhythm. Take what serves you now, add more later.

Modular

Your data stays yours

Full export any time, in standard formats. Leave whenever you want.

Reversible

Clear audit trail

Every important action is logged and exportable. For you, for your fiduciary, for your audits.

Traceability
§04The five products

Five tools, five promises.

Every product has its purpose, its trade, its price. You can use just one — the suite truly reveals itself with two or three.

§06In practice

What the suite spares you.

Four examples of what happens once your business apps stop working in isolation.

ark.planark.stock

Your clients, everywhere

Add a client in one app, find them in every other. No more double entry, no more drifting lists.

ark.planark.flow Compta

From quote to balance sheet

An invoice issued in ark.plan lands directly in your books, ready for bank reconciliation. No re-entry.

ark.planark.stock

Gear, tracked

Book an ark.stock item from an ark.plan project. Stock updates, costs roll back up to the project.

ark.flow Comptaark.flow Fiduciaire

Your fiduciary in the loop

Send your year-end file in one click. Corrections come back and the suite learns for next year.

§07Comparison

Why not the others.

We compare what can be compared. Here’s what we do differently from generic SaaS suites and legacy Swiss ERPs.

§09FAQ

The questions we hear.

If yours isn’t here, write to us. We answer personally.

Do I need to take the whole suite?
No. Each product is standalone, with its own pricing, domain and release cycle. You can run only ark.plan, or only ark.stock — the suite truly shows its value once two apps are connected.
Where is my data hosted?
In Geneva, in certified data centres powered by renewable energy. Under Swiss jurisdiction, with no transfer abroad without your consent.
How does the connection between apps work?
You enable each connection by hand from an app’s settings. Once authorised, the apps exchange the right information automatically. You stay in control: nothing moves by default.
Can I export my data?
Yes, at any time. Each product offers full export in standard formats (CSV, JSON, PDF, .ck1 for Crésus). Your data stays yours — leave when you want.
Which AI do you use?
Multi-provider: OpenAI, Anthropic, Gemini depending on the task (categorisation, OCR, extraction, classification). Routing is configurable. AI assists, it doesn’t replace: you keep the final decision. Your data is never used to train the models.
Can I connect ark to my other tools?
Yes. Each product exposes a technical interface to automate, export or hook up your own tools.
What’s the pricing model?
Monthly or yearly subscription per product, with no forced bundle. Each app is priced for its trade. No traps in the free tier, no hidden AI costs, no absurd user tiers. Details on each product site.
Who builds ark.suite?
ark.swiss Sàrl, a Swiss company based in French-speaking Switzerland. A small-shop team that builds, codes and supports directly. No resellers, no middlemen, no outsourced support.

Pick the tool you are missing.

No need to take it all. Start with one product, add the others when your workflows ask for them.
