SKU Manager reviews each listing against your buying criteria, title to photos, and puts the answer next to it in uBuyFirst Desktop. You make the call.
The title, the condition text, the photos. eBay can't filter any of them, so a person reads them, listing after listing, before a business decision is possible. SKU Manager does that review for you and saves your bandwidth for the edge cases and the rest of the business.
It reads the title and the pictures together and flags the mismatch, so the title doesn't win by default.
You tell it what tested working has to mean. It holds the seller's words to that and flags the ones that don't clear it.
Serials, cracks, cases, extras, what's really in the lot. Often the picture is the only place it lives. It reads the pictures.
Five steps, in the order you'll actually do them.
Code or AI. If the answer is a part number and a price, it's code. If it's a judgment call from words and pictures, it's AI. You can run both.
Title, condition, item specifics, price, the photos. Check the boxes. Nothing you didn't pick goes anywhere.
Your buying rules in plain language for the AI, or your Python script against your CSV. Your logic either way.
Decide what the panel shows and which values become columns in your grid, so you can sort and filter on them.
That's it. When a listing your search brings in matches, it runs automatically and the analyzed data is sitting next to it.
Your criteria, on the next listing that comes in.Set up your first profile in uBuyFirst Desktop.
AI Analysis is for the fuzzy areas: random descriptions, and pictures that say a thousand words. The Internal Endpoint is for what's highly part-specific and consistent: your list, your prices, the same answer every time. Plenty of buyers run both.

Code gates the whole stream on model and price. Only the survivors get the AI read. Pennies of compute on the stream, real judgment where it pays.
Get it down to just the data you want, with your business decisions and calculations already run.
Every field of the listing is available to the analysis, not just the ones eBay lets you search.
Turns the listing into a yes or a no against what you actually know about the item.
Clears the clear ones. Throws the handful on the edge to you.
Most arbitrage buyers are the product expert and the buyer at once. Once the criteria are written down and running, that stops being a requirement.
Someone who isn't the product expert can work the queue, with the expert's criteria and numbers next to every listing.
Go after categories you don't know intimately and still catch the one that comes along. Run while nobody is watching the grid.
Reverse it: use the rules to knock out the listings that were never going to clear, so they never reach a person.
The data and the math are at hand at the moment of decision, so fewer calls go wrong for want of a number.
The first result is whether it's an item you buy at all. Then the real questions start, and for used and gray-market stock they're the same ones every time. If you run eBay arbitrage software, you know finding the listing is the easy part. These are the things SKU Manager answers once the model matches.
Multiply your knowledge, intelligence and experience. With code.
Searching and analyzing with computer assistance, beyond aggregating the data. Four places buyers are already doing it.
"I searched a model number. Half the results are something else with the same digits."
It confirms the listing is actually the model you searched for, reads the photos for bent pins or tray-versus-box, and checks the price against your list, new or used.
You decide: buy it or pass.
"A massive buy list with a price per grade. Otherwise I'm referencing some other sheet. Impossible to manage."
It reads the card and its condition from the photos, estimates the PSA grade or calls it ungraded, and matches it to your list at that grade.
You decide: is it on my list, at my price for that grade.
"Often the only way to know what's in the lot is the picture."
It identifies the individual items from the images, catches the extras the seller didn't list, and notes cases, accessories and scratches. Video games or any consumer product.
You decide: what's really in it and what it's worth to me.
Shown: a real scrap-gold lot, build 6.18. A video-game lot shot replaces it when available.
"iCloud lock? End-user phone? Reset? Battery? Carrier? Cracks? What's in the box?"
It reads all of that from the description and the photos, confirms the model from the images, and gets it down to one number against your price structure.
You decide: buy, pass, or check on arrival.
Also in use: server RAM and PC parts against a buy CSV (the same pattern runs PC RAM arbitrage at scale), toner and industrial parts by MPN, test strips, scrap gold, watches. Larger operations with their own systems start with Custom Solutions.
Buy something that isn’t here? It runs the same way.Your category, your list, your rules.
You bring the buying criteria. The prompt, the script and the display template get written with you, one of two ways.
A set of knowledge files: what the app knows, what it has learned, use case by use case. Load it into your AI assistant and it interviews you about what you buy, writes your prompt or your script and your display template, and can write certain things straight back into the app.
Tell us your criteria and what's most important to you. We build the profile against your data and onboard you personally. Fill this in and we'll email you a copy, or schedule a call.

The analysis layer inside uBuyFirst Desktop. It reads the listings your searches bring in, title, description, item specifics and photos, against the rules you set, and gives you back the fields and the buy-or-pass signal you asked for. Two engines: AI Analysis, a language model with your prompt, and the Internal Endpoint, Python matching against your own CSV.
Not today. SKU Manager is a Desktop product, offered with uBuyFirst Desktop Enterprise. uBuyAssist, the web app, covers alerts, search and notifications in any browser, Mac included. Both run on the same listing feed; see the Desktop feature list for what Enterprise adds.
Two ways in. The Script Builder Knowledge File: load it into your AI assistant and it interviews you, then writes the prompt or script and the display template for you. Or white-glove: tell us what you buy and we build it with you. Most buyers never write a line themselves.
SKU Manager costs nothing at this launch. You need an Enterprise license for uBuyFirst Desktop and an opt-in to the SKU Manager terms. With the AI engine you bring your own API key from Gemini, OpenAI or Claude and the provider bills you directly. The Internal Endpoint runs locally with no per-call AI cost. Chaining the two keeps the AI spend to the listings that survive your code filter.
You flag it. A feedback trace saves exactly what was sent and what came back, images included, so the prompt or the template can be fixed and re-run. Results get better as you refine. It is in beta, and we would rather say so.
The SKU Manager help docs cover the quick start, prompts and templates, AI columns, the Internal Endpoint CSV setup and troubleshooting. Support and onboarding come from the uBuyFirst team directly.
