The camera reads the cert number off each slab and queues it. Rows fill in as comps land. It keeps queuing offline when the show wifi dies.
We average recent sold listings into one price and show the price at each grade. It's a number you can show the seller.
Every line gets a buy price — comp times your margin. Use a flat percentage or your buy-price rules. Override any single line by hand.
Roll the lot into an offer with a total, per-slab lines, and payment method. Make the call while the seller is still at the counter.
Paid lots lock into a receipt — vendor, total, method, timestamp. Void with a reason if you must. The trail stays intact.
Here is every piece that gets a stack scanned, priced, offered, and closed — and how each one actually works.
Point the camera at a slab. It reads the cert number off the label — PSA, BGS, CGC, SGC, or TAG — and pulls the card's identity and population. Hold the phone or set it on a stand and feed the stack; the frame stays locked, so you are not waiting on focus between cards. A good run clears about 30 slabs a minute.
Label scratched or hit by glare? Two taps to type the cert by hand. No signal? Scans queue on the device and sync the moment you are back online. Dead venue Wi-Fi never stops a buy.
Every price is the middle of recent eBay sold listings, with the obvious outliers filtered out. Tap any comp to open the exact sales it came from — date, grade, and price — so you can show the seller where the number comes from.
Each comp carries a confidence score. Thin sale counts, wide spreads, and stale data pull it down, so you know when to lean on the number and when to be careful. You also get the price at every grade, from PSA 7 to 10 plus CGC, BGS, and SGC 10, and how the price moved over 7, 30, and 90 days.
Frame a raw card and Slabbist estimates the grade it would come back as — a composite, plus sub-grades for centering, corners, edges, and surface. A confidence score tells you how far to trust it.
Centering is the easy thing to get wrong, so you measure it yourself: drag the guides or tap an edge to snap them, and read the exact left/right and top/bottom ratios. Both photos and the reasoning are saved, so you can see later exactly why a card scored the way it did.
Movers ranks the top gainers and losers for any set and price band, English or Japanese, each with a 30-day trend. Know what is climbing before you make an offer — and what is cooling before you get stuck with it.
Grade gains ranks raw cards by the profit you would make grading them to a PSA 10, after the fee. Set your real submission fee and the numbers update on the spot, so the only cards you chase are the ones worth the wait.
Set your buy-price rules once — what you pay at each price band. Every slab in the lot gets a buy price from its comp automatically, and you can override any single line by hand. The prices lock onto the offer the moment you present it.
Roll the lot into one offer: total, per-slab lines, payment method, and reference. Attach the vendor from your file in two taps. Mark it paid and it drops into your ledger. Every lot tracks its own state — drafting, priced, presented, accepted, paid — and paid lots lock so a closed buy cannot be changed.
Every paid lot becomes a permanent receipt — vendor, total, payment method, timestamp. Need to undo one? Void it with a reason; the audit trail stays intact.
Scans, edits, prices, and offers save on the device first and sync through a background queue, so nothing is lost when the Wi-Fi quits. Any failed sync surfaces in a sheet you can retry. Your store's data is scoped to your account on the server — no other shop can see your numbers.
