Why I Built HourHustle: When Tutoring Became Unmanageable

It started with a simple idea: I wanted to help students learn. What I didn't expect was how quickly my tutoring business would grow, and how chaotic managing multiple clients would become.

The Beginning: One Student, One Rate

When I first started tutoring, it was straightforward. One student, one hourly rate, one Google Calendar event. I'd manually calculate my earnings at the end of each week. Simple math, right?

But then something happened that every successful freelancer experiences: word of mouth.

The Growth: When Simple Became Complex

Within months, I had 8 different students. Sarah needed math help twice a week at $35/hour. Mike was struggling with physics and came once a week for $40/hour. Emma was prepping for chemistry exams three times a week at $45/hour. Alex was doing SAT prep on weekends for $50/hour. Jordan needed calculus review whenever he got stuck at $38/hour. Taylor wanted biology support bi-weekly for $42/hour. Casey needed statistics help with a flexible schedule at $40/hour. And Riley was working on geometry regularly at $35/hour.

The Problem: Tracking Chaos

What seemed manageable with one student became a nightmare with eight. Every Sunday, I'd sit down with my laptop and spend hours manually calculating how many hours each student had that week, applying their specific hourly rate, figuring out which sessions were completed versus cancelled, and then generating individual invoices for everyone. I had separate spreadsheets for each student and was constantly trying to remember who had paid what and when. It was exhausting.

The Weekly Struggle

Picture this: It's Sunday evening, and instead of relaxing or preparing for the week ahead, I'm hunched over my computer trying to remember if Sarah's Tuesday session was 1.5 hours or 2 hours, whether Mike actually showed up for his physics session, and if Emma's chemistry prep was $45/hour or $50/hour. Then I'd have to create separate invoices for each student, track payments in different spreadsheets, and somehow keep it all organized. This was taking me 2-3 hours every single week.

I was spending 2-3 hours every Sunday just on administrative work. That's time I could have been spending preparing lessons or taking on more students.

The Breaking Point

The moment I knew I needed a better solution came during a particularly crazy week. I had 12 sessions scheduled across 6 different students. Then Sarah got sick and cancelled her Tuesday session, Mike rescheduled his physics session to Thursday, and Emma's mom called last-minute asking if I could squeeze in an extra chemistry session on Friday. So now I had 3 different hourly rates to track across a mix of regular sessions, cancellations, and last-minute additions.

When I sat down to calculate my earnings, I realized I had made a mistake. I had double-counted one session and missed another entirely. That's when it hit me: I was losing money and time to manual tracking.

The Solution: Automation Through Google Calendar

I knew there had to be a better way. Since I was already using Google Calendar to schedule all my sessions, why couldn't I use that data to automatically track my time and earnings?

That's when I started building HourHustle. The idea was simple: connect to my Google Calendar, automatically detect tutoring sessions, apply the correct hourly rates, and generate accurate invoices.

The Results: From Chaos to Control

Once I implemented HourHustle, everything changed. Instead of spending 2-3 hours every Sunday on admin work, I was done in 5 minutes. No more calculation errors or missed sessions. My invoices looked professional and were sent automatically. Most importantly, I had peace of mind knowing exactly how much I earned each week. I was finally ready to handle even more students without the stress of manual tracking.
