Generate recurring management and financial reports from live book data instead of assembling spreadsheets by hand.
Formation, accounting, payroll and reporting share a single source of truth, reducing reconciliation and duplicate work.
Kerno approaches business admin as a single continuous workflow rather than a set of disconnected chores. On the formation side it walks a founder through the steps of establishing a company, and on the operations side it keeps books, payroll and reports in the same system so the data never has to be re-keyed or reconciled across vendors. Because it is built around European requirements — Swiss practice in particular — it speaks the language of local filing, payroll and compliance expectations instead of adapting a US-first product.
The AI layer is applied where back-office work is most repetitive: categorising transactions, drafting and parsing documents, flagging anomalies, generating management reports and surfacing what needs attention before a deadline. Rather than replacing an accountant, it is positioned as leverage — the platform handles the mechanical record-keeping and reporting so a human can focus on judgement and strategy.
Kerno is best understood as an operating system for a company's administrative spine. If you are incorporating in Switzerland or expanding across Europe and you would rather buy one connected system than stitch together formation services, an accounting package and payroll software, Kerno is the kind of tool that makes that consolidation realistic. It is not aimed at large enterprises with bespoke ERP needs; it is aimed at lean organisations that want enterprise-grade hygiene without an enterprise-grade team.
Work through formation steps in a guided flow while setting up the bookkeeping and payroll you will need immediately afterwards.
Replace a patchwork of accounting, payroll and reporting tools with one platform that keeps the numbers consistent.
Let AI handle categorisation, document handling and report generation so administrative work stops consuming founder time.
Extend the same administrative backbone as the company grows into additional European jurisdictions.
