More clients. Less routine work.
Arcarius automates routine work, closings, and financial statements based on bexio. So you can focus on what matters: your clients.
Trusted by forward-thinking fiduciaries.



50 clients, one fiduciary
Closing season means overtime, time pressure, and the risk that quality suffers with volume.
No support
You do not have employees and do not want any, but support would still be welcome, especially because you place great value on the quality of your advisory work.
Error-prone under pressure
Manual accruals, copy-paste between tools, and time pressure lead to errors – that only surface during the audit.
Scaling is nearly impossible
Growing your business is limited because your effort scales linearly with the number of clients.
