Bookkeeping for Small Business: A Simple System for Trades Owners

You didn’t start a business to do paperwork. So the receipts go in the truck’s door pocket, the invoices live in your texts, and April turns into a week of panic.

Bookkeeping doesn’t have to be a big thing. It’s just writing down money in and money out, on a schedule, so nothing piles up.

This isn’t tax advice. Tax rules depend on your situation, so check with an accountant or tax preparer.

Why bother?

• You’ll know if you’re actually making money. Busy isn’t the same as profitable.
• Taxes get easier and cheaper. You can’t deduct expenses you can’t prove.
• No surprise tax bill. The IRS says that if you’re in business for yourself, you generally need to make estimated tax payments during the year. Good books tell you how much.
• You’re ready if anyone asks. A bank, a lender, or the IRS.

Step one: separate your money

This is the single biggest thing you can do. Open a business bank account and run everything through it. Get a business card and use it only for the business.

When every business dollar goes through one account, half of your bookkeeping is already done. Your bank statement becomes your record.

What to track

Money in:

• Every payment, who it’s from, and which invoice it’s for.
• Keep your invoices numbered so you can match them up.

Money out:

• Materials and supplies
• Fuel and vehicle costs (or mileage, ask your accountant which method fits you)
• Tools and equipment
• Insurance, licenses, and permits
• Phone and software
• Subcontractors and any help you pay
• Advertising, like flyers and your website

Receipts: snap a photo the moment you get one. Phone photos in a dedicated album or folder are fine. Most bookkeeping apps can store them too.

How long to keep records

The IRS says to keep records that support your tax return until the period of limitations runs out. For most people that’s 3 years after you file, but it can be longer in some situations, and employment tax records should be kept for at least 4 years. When in doubt, keep them longer. Digital copies don’t take up space.

Pick a simple tool

Any of these work. The best one is the one you’ll actually use.

• A spreadsheet: free, simple, fine for one person with a handful of jobs a week.
• Bookkeeping software: connects to your bank, sorts transactions, sends invoices. Worth it as you grow.
• A bookkeeper: if you hate this, paying someone for a few hours a month is often money well spent.

The 15-minute weekly routine

Pick a time, like Friday afternoon or Sunday night, and do this every week:

1. Log every payment that came in and mark those invoices paid.
2. Check for unpaid invoices and send a friendly reminder (there’s a copy-and-paste one in our invoice guide).
3. Match receipts to the week’s business card and bank charges.
4. Label anything unclear while you still remember what it was.
5. Move tax money into a separate savings account. Ask your accountant what percentage makes sense for you.

Once a month: look at total money in, total money out, and what’s left. That’s your profit.

Once a quarter: check whether you need to make an estimated tax payment.

Common mistakes to avoid

• Mixing personal and business spending.
• Paying yourself randomly. Transfer a set amount on a schedule instead.
• Waiting until tax season. Twelve months of receipts is a nightmare. One week is easy.
• Forgetting small expenses. They add up over a year.
• Not tracking what’s owed to you. Unpaid invoices are money you already earned.

One flat bill helps

Predictable expenses make bookkeeping easier. Your phone bill is a good example. If business calls run through your personal cell, splitting that bill for taxes is a guessing game.

A separate business number gives you a clear business expense and a separate call history.

A business number with one flat price

GBPN is $30 a month total, taxes and fees included. It’s the same every month, so it’s easy to budget and easy to book. You get a business number that rings the cell you already carry, a greeting we record for you, and business hours so after-hours calls go to voicemail.
