Bookkeeping for Woodworkers & Makers: A Simple Schedule C Guide

Most woodworkers didn't get into the craft to do accounting. But once your hobby starts earning money, the IRS treats it as a business, and good books are what stand between you and a stressful April. The good news: bookkeeping for a one-person shop is far simpler than the software vendors want you to believe.

This is general information, not tax advice — check specifics with your accountant.

Hobby or business?

If you're making sales with the intent to earn a profit, you're a business, and your income goes on Schedule C of your 1040. Your profit — income minus legitimate expenses — is what gets taxed, and you'll also owe self-employment tax (roughly 15.3%) on that profit. The upside: every real business expense you track reduces the number you're taxed on.

Cash vs. accrual: pick one and keep it simple

• Cash basis — You record income when the money actually arrives and expenses when you actually pay. Simplest, and right for most small shops.
• Accrual basis — You record income when earned and track materials as inventory until used. More accurate for larger operations, more work for a solo maker.

For most one-person woodworking businesses, cash basis is the sane default.

The expense categories that matter

Don't over-engineer this. A handful of categories covers almost everything a maker spends on:

• Materials — lumber, hardware, finishes, consumables
• Tools & machines — anything meaningful (track larger purchases separately; some may need to be depreciated)
• Shop costs — rent, utilities, insurance for the workspace
• Vehicle & travel — lumberyard runs, deliveries, shows (track mileage)
• Fees & software — booth fees, marketplace cuts, business software
• Business meals — when they genuinely qualify

The goal isn't a perfect chart of accounts. It's clean, categorized records with receipts you can defend.

Keep your receipts attached to transactions

The single most common bookkeeping failure is a shoebox of receipts with no link to the bank line they match. When a materials charge hits your card, capture the receipt and attach it to that transaction while you remember what it was. At tax time you want every deductible expense backed by proof, without a weekend of detective work.

A 20-minute monthly routine

1. Import your bank and card statements for the month.
2. Categorize each transaction (and set rules so recurring payees auto-categorize next time).
3. Attach receipts to their matching charges.
4. Reconcile — confirm your recorded balance matches the statement.

Do this monthly and year-end becomes a formality instead of a crisis.

Where software helps

You can do all of this in a spreadsheet, and for a tiny operation that's fine. But as volume grows, a tool that imports statements, remembers your categories, matches receipts, and produces a tax-ready export saves real hours. That's exactly what ShopBooks is built to do for makers — locally, on your own machine, with no subscription and one-click year-end export of clean CSVs plus an organized ZIP of every receipt for your accountant.
