Frequently Asked Questions
How much time do consultants spend on non-billable work?
Research from Toggl and FreshBooks shows that the average freelancer or consultant spends approximately 40% of their working time on non-billable administrative tasks. Asana's data is even more stark, showing that 58% of work time goes to "work about work" — coordination, status updates, and tool management rather than skilled, client-facing deliverables.
What counts as the 'admin tax' for consultants?
Admin tax includes any work that doesn't directly generate revenue or deliver value to clients: email management, scheduling, invoicing, expense tracking, project coordination, status updates, tool management, filing, and business development. For consultants, it also includes proposal writing, contract management, and client onboarding, all of which are necessary but not billable.
How much revenue do consultants lose to admin work?
At typical consulting rates, admin time translates to significant lost revenue. A consultant billing $200/hour who spends 12 hours/week on admin loses $124,800/year in potential billable revenue. Even at $100/hour, the annual loss is $62,400. This is often the single largest drag on independent consultant income and the primary reason many feel they're working constantly without proportional earnings.
What's the best way to reduce admin time as a consultant?
The research points to a layered approach: (1) Eliminate: remove admin tasks that don't actually need to happen, (2) Automate: use AI tools like alfred_ for email, calendar, and task management, (3) Delegate: use specialized services for bookkeeping, invoicing, and tax prep, (4) Batch: group remaining admin into dedicated blocks instead of sprinkling it throughout the day. Most consultants see the biggest ROI from automating email management since it's the largest single admin category.
Is hiring an assistant worth it for a solo consultant?
It depends on your rate and volume. The math: if you bill $200/hour and an EA costs $60,000/year, you need to reclaim just 6 hours/week to break even. Most EAs save 10-15 hours/week, making the ROI clearly positive for consultants billing $150+/hour. For those billing less, AI tools like alfred_ ($24.99/month) provide similar email and calendar management at a fraction of the cost.
How does AI compare to a human assistant for admin work?
AI tools like alfred_ excel at high-volume, pattern-based admin: email triage, scheduling, task extraction, and follow-up tracking. They work 24/7, cost a fraction of human assistance, and require no training. Human assistants excel at nuanced judgment calls, relationship management, and tasks requiring phone or in-person interactions. The optimal approach for most consultants is AI for daily email/calendar admin plus a human assistant (or service) for complex coordination.
