Getting started
Your First Week With an Inventory App
Most switches to an inventory app die in the same place: day one, somewhere around card 400, with three boxes still on the floor. Here is a first week built the other way around.
You already have a system. It is a spreadsheet that mostly balances, a notebook with show totals, a cash box, and a memory for what you paid. It works well enough that replacing it feels like a project you do not have time for, which is exactly why the replacement usually stalls halfway.
The fix is to stop treating setup as a data-entry job and treat it as a trial run. The goal of week one is not a complete inventory. It is one honest end-to-end loop: cards in, cards sold, a real profit number at the end of a real show. Get that loop working on a small slice of your stock and the rest fills in a box at a time.
Day one: enter the cards you actually sell
Do not start at the front of the long box. Start with the cards that move. For most vendors that is the top row of the case, the singles priced high enough that getting one wrong costs real money, plus the handful of staples that sell at every show regardless of what is hot that month.
Thirty to sixty cards is a good day-one target: enough to make search useful at the table, small enough to finish in one sitting. Scanning is the fast path. Point the camera at a card and on-device recognition matches it against a catalog of more than 20,000 Pokemon cards and attaches its market value, so you are confirming a match instead of typing a name and a set code.
If you are still testing, the free tier covers up to 50 cards and one show, which is close enough to this exercise that you can run week one without deciding anything about Pro yet. Check what each tier includes before you plan around a feature.
Takeaway: day one ends with your case, not your collection, in the app.
Day two: pick a naming habit and stop negotiating with it
What decides whether an inventory is still usable in twelve months is whether you described cards the same way every time. Search is only as good as the words you fed it. If a card is "Charizard holo" one week and "Zard base unlimited" the next, you end up scrolling instead of searching, which at a busy table means you stop looking things up at all.
Pick one order and keep it. Name, set, number, variant, condition works for almost everyone:
- Name and set: use the set the card is actually from, not the reprint you think of first.
- Number: the collector number settles arguments about which printing is in the sleeve.
- Variant: holo, reverse holo, first edition, shadowless, promo stamp. This is where the money usually hides.
- Condition: one scale, used consistently. NM/LP/MP or your own shorthand matters far less than never mixing two systems.
Write the convention on an index card and tape it inside your case lid. It sounds unnecessary until the third show, when you are entering a buy at 4pm with a line waiting and you need the decision already made.
Takeaway: consistency beats precision. A slightly clumsy naming rule you always follow is worth more than a perfect one you follow half the time.
Day three: put in what you paid, not just what it is worth
Market value comes from the catalog. Cost is the number only you know, and it is the one that turns an inventory list into a business record. Without it you can tell a buyer what a card is worth, but you cannot tell yourself whether the show made money, and you will be reconstructing it from memory at tax time.
For anything bought recently, enter the real figure. For older stock where the receipt is long gone, use the guess-once rule: pick a defensible number now, note that it is an estimate, and move on. It stops you rebuilding the same guess every time the card comes up.
Lots are the common snag. If you paid one price for a box of a hundred, split the cost across the cards you actually kept rather than assigning it all to the one chase card, or your margins read as fiction in both directions. Longer walkthrough in tracking cost basis on your card inventory.
Takeaway: every card gets a cost, even if the cost is an honest estimate you flagged as one.
Days four and five: run it alongside the old system, not instead of it
Do not throw out the notebook yet. For a few days, log sales in both places and spend ten minutes each evening comparing them. It feels redundant and it is the most valuable part of the week, because it is where you find the gaps while they are still cheap to fix.
What the nightly compare usually catches:
- Naming drift. The same card entered two ways, which means you now have two entries and a quantity that is wrong on both.
- The trade you did not log. Trades are the easiest transaction to forget because no cash changes hands, and they quietly break both your inventory count and your margin.
- Cash-box drift. The app total and the drawer disagree, usually because of a discount given at the table and never recorded.
Fix the habit, not just the record. If trades keep slipping through, log them at the table rather than promising yourself you will catch up later. Same principle in tracking trades without losing money.
Takeaway: a parallel run is how you find out whether you trust the numbers, and a week is long enough to know.
Days six and seven: close one show end to end
Everything up to here is preparation. The test is a real show with real buyers, where you sell, trade, and buy from the app instead of the notebook, while a line is forming rather than in the quiet hour after setup.
This is what Show Mode is for. It runs the table from the phone: search your stock, ring a sale, log a trade or a buy, and watch per-show profit total as the day goes. It also keeps working when the hall wifi does not, since search, sales, trades, and buys all run on the device and sync once you are back on a signal. Show Mode is part of Pro, so plan for it rather than discovering it mid-show.
Then read the number at the end. Not gross sales, which always looks good. Sales minus the booth fee, minus what you spent restocking at other tables, against what the cards cost you. That is the figure worth judging the week on, and it is the one covered in how to read a show's real profit.
Takeaway: judge the app on whether the close-out number is true, not on how quickly you can type.
The week at a glance, and what week two looks like
| Day | What you do | What it buys you |
|---|---|---|
| 1 | Enter the case: fast movers and high-value singles | Search that is useful at the table |
| 2 | Fix a naming convention and write it down | Stock you can still find in a year |
| 3 | Add cost to every entry, estimates flagged | Margins instead of guesses |
| 4 to 5 | Run parallel with the notebook, reconcile nightly | Confidence the numbers are right |
| 6 to 7 | Work one show end to end, then read the P and L | A verdict based on evidence |
Week two is expansion, and it is deliberately boring. Add one box at a time, in the order the boxes actually sell, and keep the same naming rule. Bulk stays batched rather than entered card by card, because cataloging commons individually costs more time than the commons are worth. Method for that in pricing bulk commons without losing hours.
Takeaway: a first week that ends with one true profit number beats one that ends with a complete database you do not trust yet.
Questions dealers ask
Should I enter my whole collection before my first show?
No. Enter the cards you expect to sell, which for most vendors is the case and a few staples. A complete inventory built before you have tested the workflow usually needs redoing, because the naming decisions you make on day one are the ones you learn to regret by day four.
I already track everything in a spreadsheet. Do I start over?
No. Clean the columns so they match the naming convention you settle on, then import the file. CSV import and export both work in CardOps as a Pro feature, so your data goes in and comes back out. The column-by-column detail is in getting your card data in and out with CSV. Even so, enter twenty or thirty cards by hand first, so you learn how the fields behave before committing a thousand rows to a format you have not tested.
What happens when the convention hall wifi drops mid-show?
Searching inventory, ringing sales, and logging trades and buys all run on the device, so the table keeps moving and everything syncs once you have a signal again. That matters more than it sounds, because hall wifi tends to fail at the busiest hour rather than the quiet one.
How much of my day does the first week actually take?
Plan for a focused sitting on day one and short passes after that, roughly the length of a nightly reconcile. The workload is front-loaded on purpose. If a day starts feeling like data entry rather than preparation, you have gone past the cards that matter and should stop until after the next show.
