What software should I use to run my shop?
Short answer
One job management tool, one accounting tool, one calendar. Pick the boring ones. Don't shop forever.
The stack
Service trades: Jobber, Housecall Pro, or ServiceTitan. Books: QuickBooks Online. Email: whatever you already have. Phones: a real business number, not your cell.
The rule
Pick one in each slot in a single afternoon. Use it for 90 days before considering a switch. Most owners lose a year shopping for the perfect tool instead of using a good-enough one.
