Cal2Bill

Cal2Bill とは？

I spent 20 years manually copying Outlook calendar events into invoices. I tried Zoho Flow, Zapier, custom scripts — nothing worked properly. So I built Cal2Bill. It turns your Outlook or Microsoft 365 calendar events into Zoho Books draft invoices automatically. Per-client rates, multiple billing types, deduplication, and a preview before anything is created. Built by a consultant, for consultants. 15-day free trial, no card required.
