I used to round everything to .25 hours because that's what my invoicing tool required. Thought I was being professional. Turns out I was leaving like $400/month on the table because I'd consistently round down instead of logging the actual 8 or 12 minutes.

Started tracking exact time and holy shit, those little 10-minute client calls and quick revisions actually add up. I'm not saying nickel-and-dime your clients, but if you worked it, log it. I built a timer that just floats on my screen so I never forget to start it, and my invoices went up 15% without changing my rates at all.

Anyone else been undercharging themselves like this or am I just bad at math?

I've been freelancing for a few years and got so sick of the plugin maze. Toggl for time, Stripe for invoices, some janky CRM, proposals in Google Docs. Every tool wanted $15/month and none of them talked to each other.

So I built Tympi - one app that does time tracking, invoicing, proposals, client management, all of it. No integrations to set up, no Zapier hacks. Just log your hours and generate an invoice from those exact logs. Done.

Honestly started as a personal tool because I kept forgetting to stop timers and billing clients wrong. Added a floating timer that sits on top of other apps and auto-warns you if something's been running too long.
