From Box To P&L In Three Steps.
- 01
Scan With Your Phone
Point your phone at a slab or raw card. SlabFlow reads the label, resolves the card, and adds it straight to your inventory.
- 02
Manage In SlabFlow
Move cards from raw to sold. Tag lots, set asks, sync your eBay sales, and run your reports — all from one console.
- 03
Track Your P&L
Every sale flows back with fees, shipping, and grading costs allocated. Realized gain, holding period, and turnover ratios — done.
Pre-Grade Every Card Before You Pay To Grade It.
Photograph a card for an estimated grade before you pay to grade it. It's always an estimate, never an official grade.
Measured from your photos, with the PSA centering ceiling.
Auto-cropped corner close-ups, detected defects, and why it got that grade.
Flagged when the photos aren't clear enough.
Real grade from the SlabFlow iPhone app · an estimate, not an official grade
List On eBay From SlabFlow.
eBay sales sync, reconciled to cost basis.
Fixed price or auction.
Set a start price, a floor and a schedule, and SlabFlow steps your ask down on its own, including your live fixed-price eBay listing. It stops at the floor, and the floor can't go below breakeven unless you say so.
The nightly sync closes listings that ended on eBay and flags any that sold, with the order link, so you can record the sale.
Whatnot sync: coming soon.
When The Day's Done, Your P&L Is Already Written.
Fees, lots, grading, and shipping roll up automatically — no month-end spreadsheet.
Cost basis on every line, with grading, shipping, and eBay fees allocated back to each card.
A yearly tax sheet with your profit, fees, sales by platform and how long you held each card, ready to print.
A printable list of every card you hold, consigned cards included, with where it's kept, its value and what you paid.
Card profit, business costs and money put in, with bank or card statement import (CSV).
Track every submission from sent to returned, and AI Grade Accuracy checks the real grade against the estimate so you learn how far to trust it.
Track consignor cards, splits, and payouts, and each consignor gets a private statement link, no login needed.
