Search results overcomplicate this, so here's the straight version: no federal law prescribes a bookkeeping system for LLCs. What the law does demand is records sufficient to support your tax filings — and, less obviously, your bookkeeping habits help decide whether your LLC's liability protection would survive a courtroom. That second part is the one owners underestimate.
The LLC's core promise is that business debts aren't personal debts. Courts can set that aside — "piercing the veil" — and one of the classic factors they weigh is commingling: personal spending flowing through business accounts and vice versa, with no clean records separating the two. A dedicated business bank account, every transaction categorized, and owner draws recorded as draws is not bureaucracy — it's the paperwork your liability protection stands on. (General information, not legal advice; a lawyer can speak to your state's specifics.)
Legally, no — the law cares about the result, not who typed it. Practically, it's arithmetic: at even $50/hour of your time, five hours a month of categorizing and reconciling costs more than most done-for-you services charge. The failure mode isn't ability; it's consistency — DIY books are immaculate in January and abandoned by June, which is how catch-up projects are born.
Kai records your documents daily in QuickBooks, Xero or another platform — yours, or one we manage for you — and a person signs every monthly close. Flat monthly pricing, quoted in writing.
Yes — more than anyone. A single owner is exactly where courts look hardest at commingling when deciding whether to pierce the veil, and where the IRS looks hardest at deductions. A separate bank account plus a reconciled ledger is the cheapest liability insurance an LLC can buy.
Legally, yes — the law requires adequate records, not specific software. Practically, spreadsheets can't reconcile against bank feeds, don't attach source documents, and break silently as volume grows. Past a handful of transactions a month, a real ledger costs less than the errors.
As equity movements — draws reduce owner's equity and contributions increase it. They are never business expenses and never salary (unless the LLC elects corporate taxation and runs payroll). Misbooked draws are among the most common errors we correct in catch-up work.
