Your AI assistant for monthly closings and more.
Are you solely responsible for accounting? Arcarius has your back – with closings, professional questions, and reports. Directly connected to bexio.
Trusted by forward-thinking SMEs and fiduciaries.



Solely responsible – and no one to ask
Monthly closing pressure, ad-hoc requests, and no go-to person in the company.
Time pressure at monthly closing
2 hours per closing – every month. Management expects the numbers by the 10th. There is barely any time left for budget planning and VAT.
Error-prone under pressure
Manual accruals, copy-paste between tools, and time pressure lead to errors – that only surface during the audit.
No support
You are solely responsible for the accounting. There is no support or backup.
