Ran payroll manually for my first startup for two years before I automated it. Here's what I learned the hard way:

1. "I'll just use a spreadsheet" always breaks around 8-10 employees. That's the point where someone's PTO, a contractor's 1099, and a state tax filing all collide in the same pay period. One formula error and you've underpaid someone — or worse, missed a filing deadline.

2. Compliance isn't optional, it's silent until it isn't. Most founders don't think about payroll tax compliance until they get a notice. By then it's a fine, not a fix.

3. Payday should be the most boring day of the month. If your team is asking "did I get paid?" you've already lost. Automate it so nobody has to ask.

That's basically why I built PayFlow — automated payroll, tax filing, and compliance for startups in the 20-100 employee range who've outgrown spreadsheets but aren't ready for enterprise HR software pricing.

If you're in that stage and want to stop thinking about payroll altogether, happy to talk shop in the comments.
