How to do bookkeeping for an LLC
Bookkeeping is just the habit of recording what your business earns and spends, in a way you can total up at tax time. For most LLCs it doesn't require an accounting degree — it requires a system you'll actually keep up with.
Here's the whole process, start to finish, and how to keep it to a few minutes a week.
1. Separate business and personal money
Open a dedicated business bank account (and card) and run every business dollar through it. This one step prevents the biggest bookkeeping headache — untangling personal and business transactions later — and helps protect the liability shield an LLC is supposed to provide.
2. Record every income and expense
Each time money comes in or goes out for the business, it needs a record: the date, amount, who it was with, and what it was for. You can do this by hand in a spreadsheet, but importing transactions straight from your bank is faster and misses nothing.
3. Categorize each transaction
Assign every transaction a category — advertising, software, travel, contract labor, and so on. Categories are what turn a pile of transactions into a report, and they map directly to the lines on your tax return. Consistent categories now save hours at tax time.
4. Keep your receipts
The IRS can ask you to substantiate a deduction. Snapping a photo of the receipt and attaching it to the transaction means you always have proof, without a shoebox. Digital copies are acceptable records.
5. Reconcile and review monthly
Once a month, check that your books match your bank statement and skim for anything miscategorized. A monthly review keeps small errors from compounding and means your profit number is always trustworthy.
6. Produce tax-ready reports
The payoff: a profit & loss report that totals income and expenses by category, ready to hand to your accountant or drop onto a Schedule C. Software that keeps this updated in real time turns tax prep into a download instead of a scramble.
Frequently asked questions
Do I need an accountant to do LLC bookkeeping?
No — day-to-day bookkeeping (recording and categorizing transactions) is something most LLC owners can do themselves, especially with software that imports bank transactions. Many still hire an accountant to file the return or advise on strategy, but the bookkeeping itself does not require one.
How often should I update my books?
A few minutes weekly to categorize new transactions, plus a monthly review to reconcile against your bank, keeps everything accurate without it ever becoming a big job.
What's the easiest way to keep LLC books?
Connect a business bank account to bookkeeping software so transactions import automatically, categorize them as they come in, and attach receipt photos. That keeps your books current and tax-ready with minimal effort.
