Tonya thought her booth was profitable. Her register receipts were higher every quarter, her sourcing routes were steady, and her booth manager said her displays were among the cleanest in the mall. Then her tax preparer asked for a list of operating expenses, and Tonya realized she had been tracking three of them—rent, commission, and "supplies, kind of."
Once she actually mapped the spending, her booth's margin shrank by about a third. Not because anything got worse, but because the truth replaced the story she had been telling herself. Here is the expense map she uses now, the ones that surprised her, and how to set up the categories so this year's P&L is honest by default.
The Five Buckets That Cover 95% of Booth Costs
Tonya groups everything into five clean buckets. The detail inside each is where the discipline lives.
| Bucket | Examples | Typical share of revenue* |
|---|---|---|
| Space costs | Booth rent, commission, security deposit amortization | 20–35% |
| COGS | Purchase price of items, sales tax paid at sourcing | 25–45% |
| Supplies & display | Tags, hangers, fixtures, paint, lightbulbs, photo props | 3–6% |
| Logistics | Mileage, parking, gas, vehicle wear, tolls | 4–8% |
| Admin & overhead | Phone, software, insurance, accounting, business cards | 3–7% |
*Your geography, mall, and category mix can shift these meaningfully. The point is shape, not precision.
Bucket 1: Space Costs
The biggest line, and the one most sellers track. Rent is the obvious piece, but commission is often quoted as a percentage of sales—usually 5–15% for antique-mall consignment models—and shows up in payouts rather than as an invoice. Track commission as a separate expense line, not netted against sales, or your gross revenue and your margin both lie. For deeper context on how commission rates ripple through your bottom line, see How Store Commission Affects Your Bottom Line.
Don't forget:
- Security deposit — not technically an expense, but amortize it over your expected booth tenure to model break-even honestly.
- Holiday tag fees — many malls charge per item or per tag during peak; bake them into your December budget.
- Booth-move costs — if you re-arrange or relocate, the dolly rental and downtime counts.
Bucket 2: COGS
Cost of goods sold should already live in your inventory log. The pitfall: many booth sellers track average COGS rather than item-level COGS, which hides which categories are actually paying for themselves. Tonya now logs the purchase price of every item at sourcing time—if she can't remember after two weeks, it won't be logged at all.
Don't forget the sales tax you paid at the source. If you bought 18 items at an estate sale and paid sales tax on top of the bid, that tax is part of the landed cost of those items, not a separate ignored fee.
Bucket 3: Supplies & Display
The bucket where most sellers leak quietly. Tonya's first honest month showed:
- Price tags and tag guns: $12
- Hangers (mixed): $34
- Display risers and small fixtures: $58
- Paint and refresh supplies: $47
- Photo backdrop paper: $19
- Lightbulbs and an LED strip: $41
- Glass cleaner, dust cloths, lint roller: $14
That came to $225—almost 5% of her gross that month—on items she had previously assumed cost "a few bucks here and there." Track each receipt, then categorize once a month rather than per purchase. The friction matters more than the precision.
Bucket 4: Logistics
Mileage is the single most under-tracked deductible expense for booth sellers in the US. The IRS standard mileage rate compounds quickly:
12 sourcing trips/month × 35 miles avg × IRS rate per mile = real money on Schedule C
Tonya logs mileage in a free phone app that auto-detects trips. The first month felt like overkill. Twelve months later, the mileage line was four figures and reduced her tax bill measurably.
Don't forget:
- Parking and tolls on sourcing routes.
- Vehicle wear estimates if you do not use standard mileage.
- Trailer rental or pickup days for larger furniture pulls.
Bucket 5: Admin & Overhead
Where the boring but real costs hide:
- Phone & data proportionate to business use.
- Inventory software / spreadsheet subscriptions.
- Business insurance if your mall requires it or if you carry your own rider.
- Accountant or bookkeeping fees.
- Business cards, signage, banner reprints.
- POS or square fees for any direct-from-booth sales you ring up.
Easy-to-Miss Categories That Matter
Depreciation on Fixtures
If you bought a glass case for $400 or a set of cubed shelving for $250, you can depreciate them across their useful life rather than expensing in one month. Tax treatment varies; ask your preparer. The point is that fixtures are real assets, not vanishing dollars.
Time as a Wage Line
Not a tax line, but an operating one. If you do not assign yourself an hourly cost for the hours you spend tagging, restocking, and dusting, you will misread profitability. Many booth sellers find their booth is profitable on tax forms but unprofitable as a labor decision.
Online Listing Software
If you cross-list booth items online (some sellers do, some do not), the subscription cost belongs in admin.
Returns, Damage, Theft
Shrinkage is real in booth settings. Track it as its own line; even a 1–2% shrinkage figure is informative.
Tonya's Quick-Start Setup
- Pick the five buckets. Map every transaction into one of them on day one.
- Use a single business account or card so the statements are 80% of your work.
- Reconcile once a month on a fixed day. Tonya does the second Sunday.
- Compare year-over-year at quarter-end. Trends teach more than any single month.
The first quarter is the hardest. By month four, the process is automatic and the P&L starts telling you what to change—usually category mix, sometimes booth size, occasionally whether to stay at the mall at all.
Booth selling is a small business with a relentless cash-flow story. Operating expenses are the chapter most sellers skim. Read it carefully and the rest of the story makes more sense.
