Module 2: Business & Tax Foundations for a Home Operator

Why this matters

A reselling business that runs on vibes will eventually run on fumes. The difference between a hobbyist who "makes a little on the side" and an operator who clears ~$30k a year around a 9-to-5 is that the operator knows their numbers cold: net profit after every fee, the tax already baked into their cost basis, and the exact market signal that flips them from buying aggressively to hoarding cash. This module stands up the back office a solo home operator needs so that, when the market moves or tax season arrives, you react on pre-written rules instead of emotion.

What you'll be able to do

  • Build explicit bear / base / bull capital scenarios and act on their triggers automatically.
  • Set a daily time budget that protects deal-making as your highest-value activity.
  • Compute true net profit using realistic eBay fee stacks and Texas sales tax.
  • Stand up tax-ready records (Schedule C exports, sales-tax tracking) from day one.

Lesson 1: Bear / Base / Bull Scenario Planning

The single most expensive mistake a reseller makes is reacting emotionally to the market — doom-buying a dip because it "feels cheap," or panic-dumping good inventory at the bottom. The fix is to pre-decide your actions for each scenario so you react on rules, not feelings. You write the playbook when you're calm; you execute it when you're not.

You run three states, and your 14-day sell-through window is the primary signal:

  • BEAR — Trigger: a market drawdown of >= 30%, OR sell-through stalls for 14 days. Action: prioritize liquidity over margin. Halt new risk buys, convert slow inventory to cash, and build up your cash buffer. In a downturn the move is to raise cash, not deploy it into falling knives.
  • BASE (your default) — Recycle capital, maintain your buying/selling cadence, and grow your roster of repeat counterparties.
  • BULL — Trigger: strong sell-through for 14 days. Action: scale, but only if operations stay stable, and consolidate winnings into higher-liquidity assets.

The core guardrail in every scenario is the same: protect liquidity first. Liquidity beats ego — cash over flex. The bear case is not "lose money"; it's "fail to have cash when opportunity (or an emergency) shows up."

Decision rule:

IF inventory hasn't moved in 14 days → treat it as a bear signal → stop buying risk, start converting slow stock to cash. IF the same inventory class is selling fast for 14 days → bull signal → consolidate gains into the most liquid assets you can.

Because you work from home, your sell-through signal is already on your screen — it's your eBay and TCGplayer sold-listing cadence. You don't need a trading desk; you need to actually look at the 14-day window weekly and let it dictate your posture.

Lesson 2: Time as Capital — The Daily Budget

For a home operator running this around a day job, time is the bottleneck, so you allocate it like capital. The profiled operator runs the whole machine in roughly 100 hours per year for ~$30k profit — about $300/hour. That number is only achievable because of ruthless time discipline.

The daily allocation:

  • 50% deal-making — sourcing, negotiating, building counterparty relationships.
  • 25% logistics & ops — shipping, packing, PSA submissions.
  • 15% inventory management — pricing, listing, repricing.
  • 10% admin & tracking — books, taxes, dashboards.

Deal-making is the highest-leverage block, so you protect it first. Everything else can be batched, automated, or done tired; deal-making cannot. The rules that keep the 50% intact:

  • No doom-scrolling.
  • Don't over-optimize low-dollar tasks.
  • Batch low-leverage work into your low-energy windows.
  • Never let raw singles consume prime decision time — a $4 single is not worth a minute of your sharpest thinking.

Worked example: At ~$300/hour, an hour spent agonizing over the perfect price for a $10 raw single is a catastrophic misallocation — even if you "win" $3 of margin, you spent $300 of capacity to get it. That same hour spent landing one repeat vendor relationship can pay for itself many times over. The math is brutal and clarifying: protect the 50%, and let the cheap stuff happen in the cracks.

Lesson 3: Profit Tracking & Fee Math

The number that matters is net cash after fees and taxes, never the gross sale price. ROI computed on gross is a fantasy that hides leaks until they bankrupt you. So you track every position and compute profit the real way.

The net-after-eBay-fees rule of thumb: sold price × 0.85 (you take home roughly 85% selling yourself). That 15% haircut is the stacked reality of:

  • 13.25% final value fee
  • + $0.40 fixed per order
  • + ~2.5% tax on the fees themselves
  • + ~$5 shipping for a graded card

On the buy side, Texas retail purchases carry 8% sales tax — bake it into your cost basis. A card you paid $200 for at a Texas shop actually cost you $216. (Cash buys with no sales tax don't carry this; only retail purchases do.)

The profit formula:

Profit = (Sold × 0.85) − Sticker − Tax − Grade Fee

Worked example — a graded card flip:

  • Buy a raw card at a Texas shop: $200 sticker + 8% tax ($16) = $216 cost basis.
  • Grading fee (fee + return shipping): ~$25.
  • It sells as a PSA 10 for $500.
  • Net after eBay fees: $500 × 0.85 = $425.
  • Profit = $425 − $200 − $16 − $25 = $184.

Notice what naive math would have told you: "$500 − $200 = $300 profit." The real number is $184 — a 39% overstatement if you ignore fees and tax. That gap is exactly how operators convince themselves a thin deal is fat. (Selling the same card through PSA's own eBay pipeline nudges take-home to ~87.5%, slightly better than the 85% baseline.)

Decision rule: Before you buy to grade, compute the break-even sale price after the 0.85 haircut, the 8% tax, and the grading fee. If the expected PSA 10 comp doesn't clear that with margin to spare, there's always another play.

Lesson 4: Tax-Ready Books from Day One

Tax-ready records are not a April problem you defer — they're a day-one system, because reconstructing a year of transactions from memory is how operators overpay or invite an audit. The goal: maintain Schedule C–ready exports and a sales-tax tracker, synced via CSV/Google Drive so you can run the books remotely.

What this looks like in practice for a home operator:

  • Track every position with: raw cost, payment type (cash vs. retail, for tax), grade tier, expected value, sold price, after-fees take-home (×0.85), and computed profit. This is what makes a clean Schedule C export possible.
  • Let the platforms do the sales-tax heavy lifting. eBay and TCGplayer auto-handle sales tax on the platform, which keeps your work-from-home selling baseline compliant without you collecting and remitting per-state yourself. Your job is to track the sales-tax you pay on retail buys (the 8% in Texas) so it lands correctly in your cost basis.
  • Separate your business identity from personal credit. Stand up a distinct business identity and trade-line foundation so the business insulates your personal credit — this is the groundwork that later supports the float/credit strategy without putting your personal score at risk.
  • Run the books on dashboards and a margin calculator. Remote, leak-catching books mean you can see — at a glance — which positions are underwater after fees, which channels are slow to pay, and where margin is quietly eroding.

Checklist — your day-one books:

  • [ ] One source of truth for every position (CSV or app), with payment-type flagged for tax.
  • [ ] Schedule C export capability (categorize: inventory/COGS, shipping, grading, supplies, platform fees).
  • [ ] Sales-tax-paid tracker for retail buys (8% TX into cost basis).
  • [ ] Business identity separated from personal — distinct accounts and trade lines.
  • [ ] Cloud sync (Google Drive) so nothing lives only on one machine.

Guardrail: A typical TCG expense mix runs inventory 50–70%, shipping 10–20%, grading 5–15%, supplies 2–5%, platform fees 5–10%. If your categories don't roughly land here, either your tracking is incomplete or your model has a leak — investigate before tax season, not during it.

Action Steps (this week)

  1. Write your bear/base/bull triggers on one page and pin them where you make buying decisions — drawdown ≥30% or 14-day stall = bear; 14-day strong sell-through = bull.
  2. Audit last week's hours against the 50/25/15/10 budget. Find where raw singles or scrolling stole prime time and cut it.
  3. Recompute profit on your three most recent sales using (Sold × 0.85) − Sticker − Tax − Grade Fee. Compare to what you thought you made.
  4. Stand up one tracking sheet with payment-type, cost basis (8% tax on TX retail buys), fees, and net profit columns.
  5. Open a separate business account/identity so the business stops touching your personal credit.
  6. Set a recurring 10% admin block to keep the books current — never let tracking pile up.

Track it: Keep three things current in your books (a spreadsheet is fine): per-card and per-submission profit after every fee; an expense and sales-tax log that maps cleanly onto a Schedule C; and a simple capital/scenario view that surfaces your 14-day sell-through signal. The goal is to know your numbers cold without a month-end scramble.
