Booked straight into the calendar you already use.

Google Calendar, Outlook / Microsoft 365, and the iPhone (iCloud) calendar. You tap Connect your calendar on your settings page and sign in. For iPhone you make an app-specific password at account.apple.com and paste it in once. Some company Microsoft 365 accounts need their IT admin to approve it first. It books during the call, into the calendar you already use, so the job shows up on your phone like any other.

It re-checks your calendar right before it confirms, so if something landed in that slot a minute ago it won't double-book, it offers another time. Move or delete a job in your calendar and it picks that up. If your calendar can't be reached, it never pretends to book: the caller is told you'll text to confirm a time, and you get a "NOT booked" text. It only books suburbs you cover and never quotes outside your own price guide. Every job comes to you as a text with the recording, so you see everything. Not sure about one? Reply "I'll ring them".
