Assume you'll miss calls
Rather than trying to answer everything, build a system that captures what you miss: simultaneous ringing across the team, then voicemail-to-email, then a missed-call alert with the number. Ring back in batches between jobs.
Quoting and callbacks
Return calls from the app so the business number shows. Customers save that number, so future work comes back to the business rather than to one person's personal mobile.
As you take people on
Adding an apprentice or a second sparks is a licence change, not a new line. Numbers, routing and voicemail stay exactly as they are.
