Bookkeeping notes
What the books look like for Princeton businesses like these
Schools, associations and nonprofits
Restricted and unrestricted funds are tracked separately, grants and donations are recorded when received or pledged, and reports are laid out by program so a board can read them.
Shops and retailers
Point-of-sale totals are matched to deposits, inventory purchases are separated from operating costs, and sales tax is tracked by period. A monthly inventory and gross margin check shows which lines actually pay.
Tech, research and startup businesses
Subscription and contract revenue is recorded in the period it is earned, contractor and payroll costs are separated, software and cloud spending is tracked by vendor, and investor or loan money is kept off the income line.
General bookkeeping practice, not tax or legal advice.
Princeton businesses file with the same state agencies as the rest of New Jersey: sales tax, quarterly payroll reports, the annual report and 1099-NEC forms. See the New Jersey items we track. We work online, in accounting software you own, so you give us access to the file and your bank and card feeds and get reports and a person to ask each month.
