The problem
You've been running your collection like a business — in a spreadsheet you hate.
Every serious collector ends up rebuilding the same Frankenstein workbook: cost basis, shipping legs, grading fees, marketplace cuts, tax COGS. Hours a week feeding it. Reconciling rows before tax season. Hoping nothing's missing.
Today
Your spreadsheet.
- · 4–8 hours/week of data entry
- · Manual fee math on every sale
- · Cost basis allocation by hand
- · Tax-time scramble to reconcile
- · One typo away from a wrong P&L
With SlabCFO
A conversation.
- · 15 seconds per entry
- · Fees & ROI computed automatically
- · Schedule C-ready at any time
- · Every dollar tracked, every leg of the journey
The headline feature
Talk to your portfolio.
The front door isn't a form. It's a chat box. Type, hold-to-talk, or snap a photo. SlabCFO drafts the entry — you tap to confirm. 15 seconds per card.
Drafted from your message & photo →

Acquisitions
From sentence to ledger entry, in seconds.
The AI identifies the card from your photo and message, drafts a Holding plus an Acquisition with full landed cost, and asks for one tap to confirm. No form. No menu hunting.
Dispositions
Sales with the fee math already done.
“Sold my 2003 LeBron for $900 on Fanatics.” The assistant finds your Holding, applies the marketplace's fees, computes net payout and ROI against accumulated cost basis.
Queries
Ask anything about your collection.
“What did I pay for my Bazooka LeBron?” “Show me my biggest winners this year.” “Total at-cost in raw Jordans?” Answered inline with citations to the underlying Holdings.
Safety pattern
The AI never silently writes.
Every state-changing action becomes a draft. You confirm, edit, or reject. Every AI-created record keeps its provenance: the original message, the model, the inputs.
Type
Paste a marketplace order confirmation. Drop a one-line note. The assistant parses it and proposes the right entry.
Talk
Hold the mic button on mobile, just talk. Native speech-to-text on iOS and Android. Web uses Whisper or Deepgram.
Snap
Photograph the card at a show, in your mailroom, on the slab. Vision identifies player, year, set, parallel.
Accounting-grade ledger
Every dollar.
Every fee.
Every leg.
From the moment you buy a card to the moment you sell it, SlabCFO tracks the full landed cost — price paid, shipping in, sales tax, shipping to a vault, grading fees, marketplace cuts, promotional credits. The number you see is the truth.
Full landed cost
Every Holding accumulates its real, all-in cost basis. Compute net P&L the moment you sell.
Cost-basis allocation
$30 box yielding 5 cards? SlabCFO allocates $6 to each automatically. Override with weighted or manual splits.
Marketplace fee defaults
Configure your fee % once per marketplace. Every sale form pre-fills the right numbers.
Adjustments & credits
Refunds, eBay Bucks, insurance payouts, authentication failures — all first-class entries in the ledger.

Grading pipeline
From raw to slab,
tracked end-to-end.
Send to PSA, BGS, or SGC. SlabCFO tracks the submission, allocates the grading fee across cards, and updates each Holding's status from raw → submitted → graded — without creating a new entity. The same card's history follows it.
Submission workflow
One action creates a GradingSubmission, sets each Holding to “Sent for Grading,” and itemizes the fee per card.
Receive results
Mark received → enter the final grade per Holding. The Holding's grade updates with a full audit trail of the change.
Fee accounting
Grading fee + shipping out + shipping back + insurance all roll into each card's accumulated cost basis.
Cross-marketplace tracking
Every hop. Every fee.
Every credit.
Bought on eBay, shipped to PWCC Vault, transferred to Alt, sold on Fanatics. Each leg costs shipping. Each platform has its own fees and credits. SlabCFO records every event so the all-in cost is always right.

Tax-ready, year-round
Hand your CPA
one clean report.
Annual COGS (starting inventory + purchases − ending inventory), gross sales, platform fees, net business income — already computed. Sign-off in minutes instead of a weekend of reconciliation.
Schedule C-ready summary
Aligns to the IRS Schedule C structure your CPA already knows. No translation layer. No clean-up.
Form 8949 export (Pro)
Card-by-card disposition export with cost basis and dates of acquisition. For collectors filing capital gains rather than business income.
Audit trail
Every line on the report ties back to specific ledger entries. Drill down from the total to the individual sale.
FIFO, LIFO, or hand-pick which unit you sold
When you own multiple identical cards, choose the tax-lot method that works in your favor — and keep the receipts to prove it.
SlabCFO produces accounting summaries from your ledger. It is not a tax-advisory service — always review with a qualified CPA.
