About this guide

You're sitting in QuickBooks at 11pm trying to figure out whether Canva goes under Office Supplies, Software, Apps/Software, Subscriptions, or Other. Your accountant told you to "just be consistent" and then sent a bill for $250. You picked something, moved on, and now three months later you're staring at the same vendor and picking a different category because past-you didn't write down the rule.

That's the problem this guide fixes.

Inside, you get the rule for the 150 most common purchases a small service business makes. For each one: which category to use in QuickBooks Online, FreshBooks, and Wave, which line it lands on for Schedule C, whether it's fully deductible or not, and the most common mistake people make.

This guide is for solo founders, freelancers, consultants, agencies, and small service businesses (1-5 people) who do their own bookkeeping and file Schedule C — sole proprietors and single-member LLCs taxed as sole props. If you're an S-Corp, partnership, or C-Corp, the category logic still mostly applies, but the tax form references change.

What this guide is not: it is not tax advice. It is not a substitute for an accountant when your situation gets complex. It does not replace the judgment of a CPA who knows your books. See the closing section for the six situations where you should stop reading this and hire someone.

What you should expect: after reading Part 1, you'll understand why categories matter and what the rules behind them are. After that, you'll be able to use Part 3 like a phonebook. Look up the purchase, copy the category, move on. The whole point is that the next time you see a Squarespace charge come through, you spend 30 seconds, not 5 minutes.

How to use it

Read Part 1 once. It's about 15 minutes. After that, you'll have the mental model.

Then bookmark Part 3 — the 150-item lookup table. That's the daily-driver reference. Most weeks you won't touch the rest of the guide.

When something doesn't fit a clean category, check Part 4 (common mistakes) and Part 5 (the quarterly review). Those exist because no lookup table covers every edge case, and the edges are where people get into trouble.

Appendices A, B, and C are quick-reference: the Schedule C lines, the cross-tool category cheat, and a glossary.

Part 1 — Why categories matter

Three things connect to every expense you categorize: the IRS form you'll file, the accounting software you're using, and the deductibility rule for that specific purchase. Get any one wrong and the others still bite you.

1.1 The IRS connection — Schedule C

If you're a sole proprietor or a single-member LLC that hasn't elected S-Corp treatment, you file Schedule C with your personal 1040. It's a two-page form. Page 1 is income. Page 2 is expenses, with about 20 numbered lines. Each line is a category. The line you put your expense on affects how the IRS views it, and in a few cases, how much you can deduct.

You don't have to file Schedule C to use this guide — but understanding it makes the rest click into place. Here are the lines that matter most for a service business:

• Line 8 — Advertising. Ads, branded marketing, sponsorships, swag with your logo.
• Line 9 — Car and Truck Expenses. Business mileage or actual vehicle costs. Pick one method.
• Line 11 — Contract Labor. 1099 contractors you paid. (W-2 wages go on Line 26.)
• Line 13 — Depreciation. Big-ticket equipment you're spreading over multiple years, or Section 179'd in year 1.
• Line 15 — Insurance. Business insurance only. Not health insurance for yourself.
• Line 16b — Interest (Other). Business loan interest.
• Line 17 — Legal and Professional Services. Accountant, lawyer, business coach, consultants.
• Line 18 — Office Expense. This is the catch-all that confuses everyone. See Part 2.
• Line 22 — Supplies. Consumables. Pens, paper, ink, small tools.
• Line 24a — Travel. Flights, hotels, business trips.
• Line 24b — Meals. 50% deductible in most cases.
• Line 25 — Utilities. Phone, internet, electric for business locations.
• Line 27a — Other Expenses. A free-text section where you list things that don't fit anywhere else. Subscriptions, software, education, bank fees, merchant processing fees all live here in practice.

Line 27a is where most modern small-business expenses end up. Schedule C was designed in an era of carbon paper and rolodexes. There's no "Software" line. So software goes under Other Expenses with a label you write in yourself.

The Schedule C line you pick doesn't usually change the dollar amount you deduct — but it changes whether the IRS can quickly sanity-check the deduction. A $2,000 "Office Expense" might raise an eyebrow; the same $2,000 split into Software, Bank Fees, and Subscriptions looks normal.

1.2 The accounting software connection — Chart of Accounts

Your bookkeeping software organizes everything into a Chart of Accounts — a list of account names that group your transactions. The Chart of Accounts has nothing to do with the IRS directly. It's an internal organizing system. Come tax time, your accountant (or your tax software) maps your Chart of Accounts to the right Schedule C line.

Three things to know about how QuickBooks Online, FreshBooks, and Wave each do this:

QuickBooks Online uses a layered system. You have an "Account" (the high-level bucket — e.g., "Other Business Expenses") and a "Category" or "Detail Type" (the sub-bucket — e.g., "Apps/Software"). The Detail Type is what maps to Schedule C. So in QB, when you assign Canva to "Apps/Software," that flows to Line 27a Other Expenses.

FreshBooks has flatter, more plain-English categories. There's just "Software" or "Professional Services" — no nested detail. FreshBooks is easier to use day-to-day but you have less control over how it maps to Schedule C.

Wave sits in the middle. It has a sensible default Chart of Accounts you can customize, and the categories generally match standard accounting language. "Computer - Software," "Meals and Entertainment," "Professional Fees."

The lookup table in Part 3 gives you the exact name to pick in each of the three tools. Different software, same underlying logic.

1.3 The deductibility connection — not everything is 100%

Three rules cover 90% of the partial-deduction cases:

The 50% meal rule. Almost all business meals are 50% deductible, not 100%. You record the full amount in your books and the tax software applies the 50% haircut when filing. The TCJA (Tax Cuts and Jobs Act) eliminated the deduction for entertainment entirely starting in 2018. There's a narrow exception: company-wide events (the office holiday party, say) are 100%. Office snacks for the convenience of the employer were 100% for years; they dropped to 50% in 2024. The 100% temporary rule for restaurant meals in 2021-2022 is over.

The personal-use prorating rule. If you use something for both business and personal — your phone, home internet, home office, vehicle — you only deduct the business-use percentage. The IRS expects you to have a defensible way to calculate that percentage. A usage log for the phone. The square footage of your home office divided by total home square footage. A mileage log for the car. "I'd say it's about 80%" is not a defense; "Per my usage tracker, May was 73% business calls" is.

The expenses-vs-capital rule (de minimis safe harbor). If you buy something that lasts more than a year and costs over a threshold, it's a capital purchase and you depreciate it over multiple years instead of deducting it all at once. The de minimis safe harbor lets you expense items under $2,500 per invoice/item as if they were ordinary expenses. So a $1,200 laptop = expense in year 1. A $3,800 laptop = capitalize and depreciate over 5 years, OR elect Section 179 / bonus depreciation to expense in year 1.

Section 179 is an election that lets you fully expense a qualifying capital asset in the year you buy it, up to a generous annual limit. Most small businesses use it for any equipment purchase that's over the $2,500 threshold but they want to deduct now rather than spread out. It's an election — your tax software will ask.

That's the framework. Everything in this guide is downstream of those three rules.
