Not so important that the entrepreneur must do the accounting. It’s a skill that can be hired out better than other skills. I wouldn’t hire a financially illiterate person to run a startup, but I wouldn’t normally look for an accountant to run a startup.
If you’re business structure is “pass through” (ie. S-Corp, Partnership, Sole Proprietor), then you should also read the IRS 1040 instructions and do your taxes (mostly by hand) and file here (for free): https://www.irs.gov/filing/free-file-fillable-forms/
The IRS guide will tell you how you should handle your accounting, what you’re allowed to claim as business expenses for tax purposes, how to handle employees vs contractors, and more. Also tax deductions are crucial for businesses as they’ll help offset expenses to make your business more viable. Good luck!
Then, understanding the various reasons accounting exists: taxes, official records, but also for your own eyes and brain — they represent the health of your business!
if you have never managed your own P&L, i would definitely recommend taking some Khan Academy courses or something. understanding depreciation, cash flow, AP & AR are all absolutely necessary when starting a business.
If you are already generating revenue and there is month on month increase, then accounting is more important than product development. At this stage just hire an accountant.
