Features & How To

Scan a stack of cards, front and back. Get names and real sold prices back. Keep them in one shared inventory your whole shop can see, run breaks against them, and record what everything actually sold for.

01What it does

Six tabs. Everything writes to one shared shop account, so what one person adds, everyone sees.

Stack Scan

Front and back of up to 10 cards in the CardGauge scanner, priced together from completed sales. One tap adds them all to your shop inventory.

Inventory

Your shelf. Search it, filter it, sort it, record where each card physically is, and edit prices in place.

Break Manager

Spots, customers, spot prices. Assign cards as you pull them and verify each spot with a permanent record.

Dashboard

Realized profit from actual sales, inventory value, break profitability, and a margin guide that includes fees.

Labels

Printable price labels for the cards in your inventory.

Staff sharing

Invite your team by email. Same shop, same cards, any device they sign in on.

02Scanning a stack

Shops scan with the CardGauge scanner’s Scan a stack — the same scanner and the same accuracy checks collectors get, sent straight to your shop.

1

Open the stack scanner

From Business, the Scan cards tab → Open the stack scanner. Or open the scanner and tap Scan a stack. Be signed in as shop staff.

2

Front, then back, for each card

One card per photo, filling most of the frame. Up to 10 cards per stack.

Why: the year, card number and serial are tiny print. A card that fills the photo is read far more reliably than one card among several. The back is where the year and number are printed — skip it and the price can be for the wrong card.
3

Price all

Every card is read and priced at once — about 20–40 seconds for a full stack.

Why: each card goes through the full checks: zoomed year and serial reads, exact card number, slab grade pricing. Prices come from completed sales over the last 30 days, never asking prices.
4

Check the list

Each card shows its price, its grade price if it is a slab, or Too few sales. Tap any card for its full page: the sales behind the price, What to pay, and Fix it.

5

Add all to inventory

One tap: Add all to [your shop] inventory. Wait for the green confirmation.

Why: cards without a reliable price are added too, marked Needs review with the reason, so nothing scanned is lost from the shelf list. Pressing twice adds everything twice.
Before step 5, nothing is saved. Stack results live in that browser tab only. Reloading or closing it loses them. Add to inventory is the moment the cards become real and show up for your team.

03Inventory

Built for a shelf with thousands of cards on it, not a demo with ten.

Search everything at once

Name, year, set, card number, team, parallel, serial, condition and location — all in one box. Type murakami 503 or box 3 and it narrows.

Filter and sort

Available, Listed or Sold. Sort by newest, highest value, most potential profit, or name.

Where it is

A Where column for the box, case or binder. Write whatever your shop calls it — then search that name to pull the whole box.

Condition

A Cond column. NM, EX, 1–10, or "creased corner" — whatever your shop already uses.

Edit in place

Team, condition, location, cost and asking price are all editable straight in the row, and profit updates with them.

Bulk edit

Tick rows, or select every card matching your search, then set location, condition or status on all of them at once.

Remove one card

Each row has a Remove button. Recorded sales and verified break proof are kept.

Export CSV

Everything, including condition, location and the date each card was added. Your data leaves whenever you want it to.

Search then bulk edit is the fast path. Just scanned forty cards into one box? Filter to them, hit select all, and set the location once instead of forty times.

04Pricing so you actually make money

Set your real numbers once in Business Profile and every screen below uses them.

FieldTypicalWhat it changes
Target margin20%The margin you want to keep
Marketplace fee13%Comes off every sale
Shipping cost$1.00What it costs to post one card

The Margin & Discount Guide then shows four things per card. Margin after fees is what you really keep. Don't go below is the lowest sticker that still hits your target. Break-even is where you stop making anything. Safe discount is how far you can come down at a show.

Small cards lose money fast. On a $5 card, a 13% fee plus a dollar of postage takes about 92% of the gross margin. Cards marked no room are already at or under break-even and can't be discounted at all.

05Selling a card

Easier on a computer than a phone. Same login, same shop, same inventory.

1

Set the cost first

What you paid. Scanned cards come in at zero.

Why: profit is worked out from cost. Leave it at zero and every sale looks like pure profit.
2

Change status to Sold

Enter the real sale price and the fee you were charged.

Why: gross and net profit are calculated by the database from what you entered, so the two can't disagree.
3

Check the Dashboard

Realized Profit counts only cards sold through this form. Everything else there is an estimate from asking prices.

Why: it's the difference between money you made and money you might make.
A card can only be sold once. If two people mark the same card Sold at the same moment, the second is refused rather than recording a duplicate sale.

06Running a break

Break Manager holds the spots. The Dashboard tells you whether the break made money.

1

Create the break

Name it, choose how many spots, pick team or random.

2

Fill in each spot

Customer, team, and what that spot sold for.

Why: spot prices are where break revenue comes from. Leave them empty and the break reads as zero no matter what you took.
3

Enter your costs

Wax cost, shipping, platform fee — seeded from your Business Profile.

Why: profit is revenue minus those three. Without them you're looking at revenue, not profit.
4

Assign cards as you pull

Auto-assign matches inventory to spots by team. Anything without a team, place by hand with the dropdown on the spot.

Why: the scanner doesn't always return a team. You can type one into the card's Team column, or just assign manually.
5

Mark the spot verified

Do this once the customer's cards are confirmed. It records who verified it and when.

Why: verifying takes a permanent copy of each card — name and image — into the break itself. It stays intact even if that card is later edited or removed from inventory.

07Staff and shops

One shop, many people. Or one person, many shops.

Invite your team

+ Invite staff, by email. They sign in on their own account and see the same inventory.

Nobody else can see it

Your inventory, sales and breaks are visible only to your shop's staff. Enforced by the database, not just the screen.

Switch between shops

If you're staff at more than one, a picker appears next to your shop name. Your last choice is remembered.

Reopen any break

A picker at the top of Break Manager lists every break you have run, by name and date. Older ones can still be edited and verified.

Any device

Phone for scanning stacks, desktop for pricing and breaks. Same shop either way.

Inventory refreshes when the page loads, not live. If a colleague adds cards while you're looking at the tab, reload to see them.

08Reading the badges

Every tile says where its number came from. That's the difference between a price you can put on a sticker and one you should check.

Sold

A median of what this card actually sold for. This is the number to trust.

Ask only

No completed sales found, so this is what sellers are asking. Asking prices run high — a ceiling, not a value.

Mixed comps

Sold data exists but the sales don't agree. Usually parallels mixed in. Worth a look.

Needs review

Added without a trustworthy price or identity — the reason is listed: no reliable sold price, card number didn't match the catalog, or parallel not confirmed.

Graded price

A slab priced from sales of the same company and grade — a PSA 10 from PSA 10 sales only. The grade is added to the card name.

09If something looks wrong

Each of these has a cause worth knowing rather than a button to press.

A card came back as the wrong card

Usually the back was sideways, blurred, or under glare, so the small print couldn't be read. Turn sideways backs upright before the photo, fill the frame with the card, and tilt shiny cards away from the light.

On the card's full page, use Fix it to correct the year, colour or serial and re-price.

The year or card number says Unknown

The back photo was skipped or didn't come out. The year and number are printed on the back and can't reliably be read from the front.

The price you get is then for that player generally, not that card — which can be off by a lot. Re-scan with backs.

A common card is showing a huge price

The card was identified wrongly and the search matched something else — a sealed box or a lot. You'll usually see it flagged.

Don't add it. Re-scan that card on its own with the back captured, or remove its row from the stack first.

A price looks far too low

Cheap cards often sell at auction for almost nothing while fixed-price copies go for several times more. If the card is flagged as limited or thin, there weren't enough clean sales to price from.

Check the sold comps link on the tile and judge it yourself.

The year is wrong on a card I know

It happens. The app checks itself: if the listings it priced from all disagree with the year it read, it re-runs the search with the year the listings agree on and says so.

The card name still shows what it read. Fix it by re-scanning with the back captured, which is where the year is printed.

I added the same cards twice

Add all to inventory was pressed twice. Tick the duplicates and use bulk Remove — they'll have the same added date and the source Stack Scan.

Press once and wait for the green confirmation rather than pressing again.

My staff can't see the inventory

They need to be invited and signed in on their own account. A blank Inventory tab usually means signed out, not missing data.

If they were added while the tab was open, reload it.

10Known limits

Worth knowing before they surprise you. It is still new, and this list is honest rather than short.

Card identification isn't perfect

The same card can come back with a different card number or year on different scans, particularly without a back photo. Prices follow the identification, so a wrong read means a wrong price.

Capture backs, shoot from a distance, and check anything flagged. If a price looks wrong for a card you know, trust yourself over the app.

Two breaks with the same name look identical

The break picker lists every break by name and date. If you have run two on the same day and given them the same name, there is nothing on screen to tell them apart.

Name them something you will recognise — the product and the date, or the customer group — rather than leaving them Untitled.

There's no quantity field

Twelve of the same common is twelve rows. Fine for singles and hits, tedious for bulk.

Scan results don't travel between devices

A stack scanned on a phone lives in that phone's tab until you tap Add all to inventory. Only saved inventory is shared across devices and staff.

Prices are a guide, not an appraisal

They come from completed eBay sales over the last 30 days. Thin markets, parallels and condition all move real value in ways a median can't see.
