# Work In Passes: The Batch Habit That Makes Inventory Days Short
Ask a reseller what took all evening and the answer is almost never one hard job. It is forty small ones done in the wrong order. Photograph an item, write it up, number it, price it, list it, put it away. Then the next item, from the top. Every switch between those jobs costs a little, and forty items times six switches is where the evening goes.
The fix is old and boring and it works: do one job across the whole pile, then the next job across the whole pile. Work in passes.
Why Passes Beat Per-Item
Each job has a setup cost. Photographing means the light is on, the sweep is clean, the phone is in your hand. Numbering means the label roll is out and the marker is uncapped. Pricing means you are looking at sold listings. When you do those jobs one item at a time, you pay every setup cost forty times. When you do them in passes, you pay each one once.
There is a second effect. Doing the same job over and over makes you fast at it. By the tenth case you are photographing on rhythm. By the tenth price check you know what the category is doing today and you stop second-guessing. Per-item work never lets you get that rhythm.
The Four Passes
The photo pass. Everything through the light, one after another. Front, back, spine, open. Do not stop to write anything. If a case needs a wipe, wipe it and keep moving. The only decision in this pass is whether the item is worth listing at all, and you already made that when you bought it.
The numbering pass. Every item gets a SKU that says where it lives. Do the whole shelf in one run, in the order the items sit, so the numbers and the physical order agree. If you use FlipPress on the web, Batch Edit has a Sequential Mode for exactly this: set a prefix and a starting number, then tap each listing and it takes the next SKU in line, and tap Done to save them all at once. Eight items, eight taps, nothing typed. The SKU it saves is on your FlipPress listing, which is where you will look it up later.
The price pass. Open sold listings once and price the whole batch against what actually sold, not what is asking. Because you are looking at one category for twenty minutes, you catch the outliers instead of anchoring on them. Write the number down and move on. Pricing is a decision, not a debate.
The listing pass. Now the drafts get finished and sent live. This is the pass where a photos-to-draft tool earns its keep. In FlipPress, you drop the photos in and it drafts the listing for you, with the title, category, item specifics and condition filled, so the listing pass is a review pass, not a writing pass. You still set the price, because you decided that in the pass before.
The Rules That Keep Passes Honest
Never let an item skip a pass. The one that "just needs a quick write-up" is the one that sits in the draft folder for three weeks. Every item goes through every pass in order, or it waits for the next batch.
Keep the batch small enough to finish. Twenty items is a good evening. Sixty is a good weekend. A hundred is a death pile with a schedule.
Put the batch away in the same pass you number it. The point of a SKU is that the number and the shelf agree. Numbering on the desk and shelving next week breaks the link.
A Realistic Evening
Shelf of twenty cases. Photo pass, phone in hand, no typing: about the length of one podcast episode. Numbering pass, one run down the shelf. Price pass with sold listings open, one category at a time. Listing pass, reviewing drafts that are already written. The whole thing fits in an evening, and it fits because you never once picked up the marker, put it down, opened a browser tab, closed it, and picked up the phone for the same item.
The pile does not get smaller because you work harder on each item. It gets smaller because you stop paying the switching cost. Work in passes, and the boring parts get a rhythm instead of a dread.
