The opposite of a platform:
five tools that speak the same language.

Four independent tools — calendar & CRM, gear management, accounting, fiduciary — that share one language while each stays in its lane. Hosted in Switzerland, AI assistant, handcrafted.

§04The five products

Five apps,
five everyday lives.

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

speak to each other.

What flows, in practice.

Every cross-app connection shipped or planned. Filter by app, by data type or by status to see what covers your day-to-day.

11 connections of 11
ark.planark.flow ComptaInvoicesLive

Your invoices land in accounting

When you issue an invoice in ark.plan, ark.flow Compta receives it as a document with the PDF and all metadata (number, amounts, client, date) — ready for bank reconciliation.

ark.stockark.planInvoicesLive

Invoice a gear project through ark.plan

On an ark.stock project, the “Invoice via ark.plan” button sends the bundle (items, discounts, client) to ark.plan which creates the quote with its own numbering. Single source of truth for every commercial document.

ark.flow Comptaark.stockItemsLive

Gear purchases detected by AI

When ark.flow Compta detects a gear-purchase line on a supplier invoice, it shows up in ark.stock as an item suggestion — you approve, the item is created with name, brand, model, SKU and price already extracted.

ark.planark.stockClientsLive

Your contacts shared and searchable

Your clients exist once and are visible from every app in the suite. Search works in both directions, and duplicates are detected automatically with a “merge” button on the ark.plan side — no drifting lists.

ark.stockark.planProjectsLive

Project P&L, without spreadsheets

On the ark.plan project page, you see the margin in real time: revenue + cost of items sold + supplier invoices tagged to the project (coming from Compta). No double-counting.

ark.planark.stockProjectsLive

Reserve gear from the project

Create a project in ark.plan, pick the ark.stock gear for the date window — it is reserved. Cancellation is also available: capacity is freed up for other projects.

ark.stockark.planItemsLive

Your items available in ark.plan

When you add an invoice or quote line in ark.plan, you find the items from your ark.stock catalogue — name and reference picked up automatically, no retyping.

ark.flow Comptaark.flow FiduciaireDocumentsLive

Your tax documents reachable by your fiduciary

You (client) authorise your fiduciary firm to access tax documents stored in ark.flow Compta — salary certificates, 3a / 2nd pillar attestations, deduction supporting docs, bank statements, balance sheets. The fiduciary reads them from their own instance, no manual transfer. Permanent link, revocable from both sides at any time.

ark.flow Fiduciaireark.flow ComptaDocumentsLive

Your fiduciary feedback lands in Compta

When your fiduciary asks you for a missing document (“please send me your 3a attestation”), annotates a supporting doc, or sends back the finished document (finalised tax return), everything lands directly in ark.flow Compta — no email, no Dropbox.

Every app in the suiteDocumentsLive

Your apps discover their siblings automatically

Once the OAuth connection is enabled between any two suite apps (ark.plan, ark.stock, ark.flow Compta, ark.flow Fiduciaire), each one knows its siblings and displays in Settings the list of linked apps with live health status.

Every app in the suiteDocumentsLive

No data lost between your apps

If data fails to move from one app to another (network outage, target app momentarily down), the suite retries automatically several times. If the failure persists, the source app shows an alert with the details — you know exactly what didn't get through and why.

§09FAQ

The questions we hear.

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

Do I have to take the whole suite?
No. Every product is self-contained, with its own price, domain and release cycle. You can run ark.plan alone, or ark.stock alone — the suite only really 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 outside Switzerland 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 data automatically. You stay in control: nothing flows by default.
Can I export my data?
Yes. Every product offers exports in standard formats: CSV for lists (clients, items, journal entries), PDF for issued documents (invoices, quotes, tax files), plus trade-specific formats — .ck1 for Crésus on the Compta side. Attached files stay downloadable one by one. Leave whenever you want.
Which AI do you use?
Four providers, picked per user inside each app: Infomaniak (Qwen, Kimi, Mistral — hosted in Switzerland for full sovereignty), OpenAI, Anthropic and Google Gemini. You pick the mix that matches your requirement — maximal sovereignty or state of the art. AI assists, it does not replace: every suggestion is approved by you. Your data is never used to train the models.
Can I connect ark to my other tools?
Yes, but each app has its own connections, picked for what makes sense for its trade. ark.flow Compta: bank imports (PostFinance, Migros, Stripe, PayPal, Viseca), native Crésus export (.ck1). ark.flow Fiduciaire: Dr.Tax import. ark.plan: Google Calendar, IMAP/SMTP for email, Odoo for outbound invoices. Every product exposes an API for your own automations. For tailor-made connections (Bexio, industry ERP, customer platform), we build them on request.
What is the business model?
Monthly or yearly subscription per product, no forced bundle. Every app has its own pricing tailored to its trade — some (ark.stock, ark.plan) scale price with team size (1, 5, 10 users or unlimited), others (Compta, Fiduciaire) bill per client or per file. No misleading freemium, no hidden AI costs, no surprises on the invoice. Details on each product site.
Who publishes ark.suite?
ark.swiss Sàrl, a Swiss company based in French-speaking Switzerland. A small workshop team that builds, codes and supports directly. No resellers, no middlemen, no outsourced support.

Pick the tool you are missing.

Every product can be used alone. The suite truly reveals itself once two apps are connected — when you decide.
