It's not just the hours. It's the compounding cost across your week, your family, and your win rate.
The wage tax
You wouldn't charge a client for 10pm hours. So why are you doing them for yourself? Every after-hours quote is billable-rate work being done at zero pay — often at 40% quality.
The decision-fatigue tax
Late-night quotes miss things. Wrong material assumptions. Forgotten line items. Underquoted by mistake because the day was too long. This is where owners lose 5-10% margin — one bad estimate at 11pm at a time.
The family tax
This one doesn't show up on the P&L, but it shows up everywhere else. Fixing the quoting flow gets you two nights a week back — that's what matters.
Frequently asked
Isn't after-hours work just part of running a business?
For emergencies, yes. For quoting, no. Quoting is a system problem, not a discipline problem.
