Hey Product Hunt 👋 I'm Guido, an independent IT consultant based in Canada. For 20 years I manually copied Outlook calendar events into invoices at the end of every month. I tried Zoho Flow, Zapier, and even wrote my own Deluge scripts. Nothing worked the way a real consulting practice actually works; different rates per client, multiple billing types, no preview before anything hit my client's inbox. So I built Cal2Bill. It connects your Microsoft Outlook or Microsoft 365 calendar directly to Zoho Books. Mark your billable events with an Outlook category, include the client name in the title, and Cal2Bill handles the rest; per-client rates, deduplication, billing types, and a full preview before anything is created in Zoho Books. I'm also looking for 5-10 beta testers: 6 months free in exchange for honest feedback and a testimonial. If you bill hourly from a calendar, I'd love to have you involved. 15-day free trial, no credit card required. Would love your feedback, especially from anyone who's lived this pain!
