One business account and a Friday habit beat any software

Quick answer: Open a checking account that only the business touches. Put every business expense on one card. Spend twenty minutes every Friday sorting what came in and went out. Hand the result to a CPA once a quarter. That's the whole system.

Picture the last Saturday in March. You're at the kitchen table with a banker's box of receipts, half of them faded to blank, and a bank statement where a $212 supply house charge sits next to a $212 family dinner. Your wife is in the next room, and she knows exactly where you are and why.

Nobody gets into a trade to do this. So most guys do it once a year, badly, and call it bookkeeping. It isn't. It's an annual rescue.

Separate the money first

Software doesn't fix a mixed-up account. Separation does.

Open a business checking account. Every dollar a customer pays you goes in there. Every business cost comes out of there, or off one business card that you pay from there. Nothing else touches either one.

You pay yourself by transferring a set amount to your personal account on a set day. Call it a paycheck, because it's one. If you pay a personal bill out of the business account, or a materials bill out of your personal one, you've made an hour of cleanup for later. If it happens by accident, move the money back the same week. Square it before anybody has to ask.

This one step turns your bank and card statements into most of your books. Everything in the business account is a business transaction. No guessing.

Check whether your bank charges monthly fees on a business account and whether they're waived at a minimum balance. Many are. Ask before you sign.

The Friday twenty minutes

Pick a day and a time and put it on the calendar like a job. Friday afternoon works because the week's still fresh. Do these four things in this order:

1. Sort the week's transactions. Log in, look at each line, and give it a category.
2. Match receipts. Anything without one, find it now. A supplier will email you a copy in about a minute. In January, it'll take an afternoon.
3. Check who owes you. List every open invoice, how much, and how many days old. Anything past thirty days gets a call Monday morning.
4. Move the tax money. More on that below.

Twenty minutes. If it's running past thirty, you've got too many categories or too many weeks stacked up.

Keep the categories boring

You don't need forty. Most one-man trade businesses can live on a dozen: materials, fuel, tools and small equipment, vehicle costs, insurance, phone, software, licenses and fees, subcontractors, advertising, meals, and office or shop. Your accountant may want one or two more. Ask what they use and copy it, so their work and yours line up.

When a purchase doesn't fit, don't invent a category. Pick the closest one and add a note. Your CPA would rather read "chainsaw chain, rental yard" than a category called Misc that holds $4,000.

Receipts: the tailgate rule

When you pay, you photograph. Before you start the truck, take a picture of the receipt with your phone and drop it in a folder, or send it to a dedicated email address. Paper thermal receipts fade in a hot cab within weeks. The photo doesn't.

The IRS expects you to be able to back up what you deduct. How long to keep records depends on your situation, and the usual window is a few years. Ask your CPA for the exact number for you. Digital copies in a folder named by year cost nothing and don't take up a closet.

Spreadsheet or software

A spreadsheet works fine for a guy with one truck and a few dozen transactions a month. Date, who, what, amount, category, receipt filed. It's free and you can't be locked out of it.

Accounting software, QuickBooks being the best known, starts earning its fee when you have invoices to track, sales tax to collect, or an employee to pay. It pulls in your bank feed so you're categorizing instead of typing. It also produces the reports your accountant and your lender will ask for.

The right choice is the one you'll open every Friday. A $40-a-month program you avoid is worth less than a spreadsheet you finish.

The tax set-aside belongs in the system

The ambush in April is almost always a cash problem, not a math problem. You earned the money and spent it before you knew it was owed.

So make the set-aside part of Friday. This is an illustration, not advice: say a customer paid you $6,000 this week, and your accountant has told you to hold back 25 percent. You transfer $1,500 into a separate savings account labeled for taxes. You don't touch it except to pay the government. Your CPA will give you the real percentage for your situation. The habit works at any number.

I covered how the quarterly payments work in Quarterly taxes and the one rule that ends the April ambush. The set-aside is what makes that rule painless.

Know what the books are telling you

Once a month, after your last Friday session, look at two numbers: what came in, and what's left after the real costs. Not what's in the account. Money in the account includes the tax set-aside, the deposit on a job you haven't started, and the truck payment due Tuesday.

This is where books earn their keep. They'll tell you the truth about the jobs you suspected were losers. If you've felt buried in work with nothing to show for it, the numbers will show where it's going. That ties straight into Your seventy-hour week is a pricing problem, because you can't fix a price you've never measured.

When to hand it off

There are two good reasons to hire a bookkeeper. The first is that your Friday sessions keep slipping. The second is that you've hired your first helper and payroll just got complicated. Employees bring withholding, deposits, and forms with deadlines and penalties. That's when Your first helper is probably an employee, not a 1099 guy matters, and it's when a professional's fee costs less than one mistake.

Even then, the system stays. A bookkeeper working from clean, separated accounts costs far less than one rebuilding a year from a shoebox. Ask what they charge, then ask what they'd charge if you showed up like this. They'll say less.

One test

Suppose you got hurt next month and were off the job for ten weeks. Could your wife, or a partner, or an accountant open your books and know who owes you, what's due, and where the tax money is? If not, you've got a system that only works while you're standing.

Build one that doesn't need you in the room. It's a better thing to leave your family than a banker's box.
