As you start selling more and more, you will inevitably start to develop repeat buyers. The same people keep coming back, they have specific tastes, and when you have the right card they almost always say yes. Until now, whuppit had no good way to track those relationships. That changes today.

Buyer tracking is now available to all paid subscribers — and with it, a new way to turn your collection management into a personal storefront for your best customers.

You can now create a buyer record for anyone you sell to regularly. Each buyer gets their own profile where you can:

Your buyers list has full filtering and search, so even if you have dozens of customers you can quickly find who you're looking for — filter by platform, sort by total spent, or search by name or handle.

Here's where buyer tracking and collections come together.

From any buyer's profile, you can create an Active Offer Collection — a dedicated collection just for that buyer. Add the cards you think they'd want, set asking prices on each one, then share a single link. Your buyer sees a clean, visual page showing exactly what you have available and what you're asking.

No spreadsheets, no DMs with a wall of text, no back-and-forth. Just a link.

You can also do this with any regular collection — create a collection, bulk-add cards from your inventory using the new inline typeahead in your card table, set asking prices, and share. The share link doesn't require your buyer to have a whuppit account.

To help make the new buyer and bulk selling flow more powerful, collections got a significant round of improvements:

That's it. Your buyer gets a clean, shareable page showing exactly what you have for them.

As always, I'd love to hear how you're using this — especially the offer collection flow. Drop me a note if you run into anything or have ideas for what would make it even more useful.

When you create an eBay listing from whuppit, you now have full control over exactly which images get sent—and how they're created.

whuppit has always used PSA scans to automatically create images of the front, back and a side-by-side for your eBay listing, with an optional background image applied automatically.

Now, you can include up to six images in each listing. If you've uploaded extra images to a card, they'll automatically be included when you create an eBay listing.

From within the listing page, you can also choose whether or not to apply your custom background image on a card-by-card basis.

Previously, with only the three auto-generated images, you were limited in what you could send to your eBay listing. Time spent viewing your listing is an important criteria in eBay's "best match" search, so having more images can be very beneficial—more images to look at means more time spent on the listing itself.

This is particularly handy for cards with serial-numbers, where you can now upload a close-up of the serial-number to show potential buyers.

This is also a necessary step towards unlocking the ability to create eBay listings from within whuppit for your inventory, not just your PSA cards. Stay tuned for more on that soon.

This is now available for all users with eBay connected to their account.

As always, let me know how this is working for you—feedback is welcome!

Managing your card inventory just got a lot faster. You can now take common actions directly from your card list—no need to open the full edit form just to mark something sold or add grading details.

From any card row, click the action dropdown to access:

Each action opens a compact dialog pre-filled with what we know about the card. Make your changes, hit save, and the row updates in place—no page reload, no losing your scroll position.

This is available to all users starting now.

As always, let me know how this fits into your workflow and what other features would help make whuppit more useful for you.

Along with being able to track and record key milestones for your submissions (when they were created, arrived for grading, grades popped and received back), you can now also sort and filter your submissions by those same milestones.

This makes it possible to quickly find your orders as well as drill in more easily into your submissions over time or during a particular period to see a detailed overview of all orders that match that time period so you can easily spot-check gem rates, profit, pre-grade accuracy and more.

You can now automatically import your eBay purchases directly into whuppit! When you win an auction or buy a card on eBay, it shows up in your Pending Purchases, ready for you to review and add to your inventory—no more manual entry needed.

This feature is available now for all Premium and Unlimited plans at no extra cost.

Once you've connected your eBay account to whuppit, the process is completely automatic.

The purchase shows up immediately in your Pending Purchases with an estimated total cost. You'll see the card title, seller information, and what you paid (or are expected to pay).

whuppit updates the purchase with the full cost breakdown—item price, shipping, taxes, and any eBay fees. Now you have complete visibility into exactly what that card cost you, down to the penny.

When you're ready, you can review the purchase and fill in any additional details you want.

Here's where it gets really handy: you can search GemRate directly from the review page to find a match for your card. When you find it, whuppit automatically imports all the card details—year, set, player, card number, parallel, even whether it's autographed.

Once you approve the purchase, the card shows up in your inventory as "incoming" with the full purchase price breakdown, seller information, and purchase date all automatically populated.

You can also reject any purchase if it's something you don't need imported into whuppit—maybe it was a gift, or a personal collection piece you don't want to track. Just hit reject and it disappears.

This feature tackles three big pain points at once.

Every time you buy a card on eBay, you used to have to manually add it to whuppit—type in the card details, enter the purchase price, remember the seller, note the date. For folks buying multiple cards a day, that adds up to a lot of tedious data entry. Now? It just shows up automatically. You review it, approve it, and move on.

One thing that's come up repeatedly is that it's easy to lose track of which purchases haven't shipped yet. That matters because eBay gives you a limited window to request a refund if a seller doesn't ship. Having all your pending purchases in one place makes it much easier to spot when a seller is taking too long, so you can follow up with them or contact eBay before that window closes.

Between the automatic cost breakdown and the GemRate search integration, you get detailed, accurate information about each card and exactly what you paid for it. That means your profit calculations, ROI tracking, and inventory reports are all based on real data, not rough estimates or whatever you remembered to type in.

To use this feature, you'll need:

That's it. Once connected, any eBay purchases you make will automatically start showing up in your Pending Purchases.

I've been using the feature myself for a month or so now, and quite a few users have been testing it as well—things seem to be working well.

If you do encounter any issues or have ideas for what should come next, please let me know: tim@whuppit.com.

The current version works great for individual card purchases, but I know a lot of folks buy multi-card lots (like a 20-card lot listing). Making it easier to split those into individual cards is high on the list for future improvements.

I also have some ideas for improving incoming shipment tracking, automatically leaving eBay feedback and more.

As always, feedback is welcome! I'm excited to see how this changes your workflow, and I'd love to hear what other improvements would make this even better.

The Profit Evaluator just got a major upgrade! You can now save your best grading targets for quick reference, and the calculator itself has been completely overhauled with better guidance, clearer metrics, and a more intuitive interface.

When you find a profitable grading opportunity in the Profit Evaluator, you can now save it as a "Grading Target" with optional notes about condition details, where to source the card, or anything else you want to remember.

All your saved targets are available in the new Grading Targets page, where you can:

The Profit Evaluator now provides much clearer recommendations about whether a card is worth grading.

You'll now see:

These improvements make it easier than ever to:

These features are live now for all users, right now.

The Profit Evaluator is available for unlimited use for all customers, today, no matter what plan you're on. Starter plans are able to save up to 10 grading targets to keep track of. Premium and Unlimited accounts can store an unlimited number of targets.

As always, feedback is welcome. Let me know how you're using these features and what else would make them even better!

You can now view all cards in a bulk import for easy editing and deletion of cards using the new Import History.

Importing purchases and sales in bulk has become an increasingly popular way for users to quickly get large amounts of inventory added to the site, so it made sense to give you more control over those imports.

Each new import will now get added to your Import History, so you can quickly view the results. You can view and edit any cards in a particular import using the View link.

You can also now delete certain cards from an import, or even an entire import altogether in case there was a mistake during the import process.

The "Delete" button on the import history itself will mass delete the import and all cards associated with that import.

Alternatively, you can view the cards in the import, select the specific ones you would like to remove, and then Delete them with the new bulk delete functionality.

Bulk imports are a powerful and flexible way to quickly add large amounts of inventory to whuppit, and these features should make it much easier to manage your past imports and keep your inventory clean and tidy.

You can now create listings on your eBay account, directly from whuppit! This feature is starting to roll out (contact me if you want immediate early access) for all and plans.

I'm also using this as an opportunity to make plan better, by and giving every plan access to both Collections and the Profit Evaluator.

To date, whuppit has mostly been focused on reporting and analysis. By giving you a way to easily keep tabs on your inventory and sales, as well as giving you detailed, comprehensive reporting capabilities, whuppit's aim has been to give you all the information you need to be able to make better decisions about what to grade and fine-tune your business.

But the ultimate goal has always been to help every whuppit user make more profit selling cards (and have fun doing it).

There have been a few improvements lately to help with that from the addition of collections, to the profit evaluator tool.

But the latest, and arguably biggest, change is the new ability to connect your eBay and whuppit accounts, so you can create eBay listings directly from within whuppit, helping you not just keep better tabs on your inventory, but get your cards listed quickly and efficiently.

The eBay integration lets you create both Buy It Now and Auction listings directly from whuppit, for all PSA graded cards (I'll be working on adding support for other cards as well). All the options you would expect are there. You can choose to accept offers and provide a minimum offer price, as well as an auto acceptance price.

You can choose to schedule your listing, selecting the day and time you want it to go live.

whuppit will use all the data it has about your card to fill is as many of the eBay attributes as possible. It will also automatically generate three images for the listing:

On top of that, you can define saved templates for your title and description, with placeholder substitutes so that whuppit can fill in the details dynamically.

You also have the ability to provide an optional background image to be used on all your listing images, letting you a create a consistent, branded experience on your eBay account.

You can learn more about the eBay connection in the new, still-very-much-in-progress-so-please-don't-judge-me-too-harshly whuppit docs.

Every account, on every plan, effective immediately, now can track and record grading, sales and profit data for . You don't have to do anything to get unlimited tracking—it's just there, no extra cost.

I know some folks may not want or need eBay listing capabilities, so I wanted to make sure there was a way to get all the tracking capabilities by default.

In fact, . Instead, each plan is just getting a bit more powerful.

Here's what's new for each:

The starter plan now has unlimited tracking. Starter plan users also get 5 active collections at any point in time, as well as full access to the profit evaluator to help you find more profitable grading targets.

The premium plan also now has unlimited tracking. You also now get unlimited access to the new collections feature, as well as full access to the profit evaluator tool. On top of that, you premium users can create 25 eBay listings a month, with access to all the eBay listing functionalities.

Unlimited users always had unlimited tracking, but you now get to create an unlimited number of eBay listings a month, all without ever leaving whuppit. You also get unlimited collections and full access to the profit evaluator tool. Basically, unlimited is...well...unlimited.

Unlimited tracking cards is already turned on for all plans, as of today. Just to stress it in case it wasn't clear: you do NOT need to pay any extra or upgrade to get access.

For premium and unlimited users, I'm starting to roll out the eBay functionality and you should see it appear in your account within the next week. Again, if you want immediate access, just drop me a note and I'll make sure to turn it on for your account ASAP.

The eBay functionality is really just getting started. I've been using it for awhile now, and a few early users (thanks for your feedback!) have as well, but there may be wrinkles. If so, just get in touch.

Right now, the listing functionality is limited to PSA only because the card images were already handy and I had to start somewhere. I'll work on getting it expanded until eventually, you can list anything and everything in your account.

There's much more planned to make the process of selling, and sourcing, more efficient so you can spend more time on the fun part of this hobby: the cards themselves. So stay tuned!

And as always, thank you all for your support and feedback! whuppit has gotten better and better and it's because of all the great feedback and input you all have provided along the way!

The Profit Evaluator tool now let's you check profit efficiency not just for PSA, but for Beckett, SGC and CGC as well, letting you compare the potential profit for each company. It also now surfaces both the break-even grade for each company (the lowest grade you can get and still be profitable) as well as the total population above the break-even point.

The Profit Evaluator tool still defaults to PSA data—it's by far the most common grading company used by whuppit users—but with increases in PSA turnaround times, and changes to grading, more users have been asking about other options.

The new changes to the tool now make it possible to quickly compare profit efficiency across different grading companies. When you select a card, the population data for PSA, BGS, SGC and CGC is automatically requested. Any of those companies that have graded copies of that card will display as options for you to choose.

You can enter comp values for the grades for each company and then quickly toggle from company to company. The values you entered will be retained so that you can quickly compare the profit potential.

Not only can this be helpful in letting you make the right decisions about where to send your cards, but it can help you find potential options for cards that may not be quite gem worthy.

Let's look at an example.

2024 Prizm has had some awful quality control issues, and as a result, it doesn't grade very well. Looking at the base Caitlin Clark rookie (#22), there's only a 28.2% gem rate for PSA. On top of that, we lose money on anything other than a 10 (our break-even grade).

The upside on a 10 is significant, however, so all-in-all it still ranks pretty high with a profit efficiency factor of 1.436.

If we look at the SGC data, we again see a pretty low gem rate—26.2% get an SGC 10. The upside is nowhere near as high as a PSA 10, so our overall profit efficiency factor is much lower—.672. The right play here in terms of upside is PSA.

However, notice that our break-even grade for SGC is actually a 9. As a result, 81.9% of the total SGC population is actually profitable based on current comps.

If we look at the percentages, based on current comps, 82% of all copies of this card graded by SGC are actually profitable.

Using this data, we can come up with a pretty reasonable strategy to maximize our potential profit on this card:

These new changes to the tool should make it easier than ever to compare across grading companies and find ways to eek out every bit of potential profit.

You can now organize cards into collections to help you keep better tabs on your own personal collections, or share inventory lists on Discord, Facebook, X or wherever else you sell cards!

Now inside of whuppit, you have the ability to add cards to a "collection". Each card can belong to any number of collections—from 0 to as many as you would like.

Each collection has a public link that you can choose to use if you want to share your collection with anyone—whether to show cards you have for sale, or simply to showcase some of your favorites.

I've been using the feature myself for awhile to try to iron out the wrinkles. Here are a couple of examples of how I've used them.

Ok, look, sometimes you're just really excited about some cards and it feels good to let someone else enjoy them too. I am obsessed with this year's Topps Black & White baseball cards and have graded a fair share. I was chatting with someone and found myself sending a few individual pics, so I put together a collection of what I currently have (meaning, I haven't sold them yet) and shared the link with them instead, letting them look through the collection for themseles.

One thing I've noticed in Discord groups, Facebook, Twitter—really any location people are trying to buy cards—is that people will often post specific players they're looking for and ask what is available.

I've also seen sellers, on Discord in particular, provide spreadsheets showing their current inventory.

Using the new collections functionality, you can create your own inventory collections for sharing. Each card can now have an "Asking Price" that you can set. Whenever a card has an asking price, that price will be displayed within the collection. Each collection also has an optionally shareable public link, so instead of answering with a list or spreadsheet, you can now provide a nice visual way for buyers to quickly see what cards you have available and for how much.

For example, someone was looking for De'Von Achane cards, so I created a quick collection of Achane's I had available and sent them the link. As cards are sold, I just remove them from the collection and keep that inventory accurate and up to date.

I sell almost everything through eBay, but I've started testing the waters on Discord and Facebook a bit more. Because Discord and Facebook postings get buried over time, it's a LOT harder to keep track of what you posted. So I started a little "Discord Inventory" collection for myself.

When I post a card for sale on Discord, I add it to that collection so I can go back and remind myself which cards I've listed there.

Collections are really kind of open-ended, and I'm sure there are a ton of different ways to use them. I know several people have wanted this feature for keeping tabs on their own personal collections

in a more visual way, or tracking set progress.

Collections are in beta, which means there's a lot more I'm expecting to add here over time. I'm already exploring different ways that grading population data might be useful here, how we could make things like tracking a particular set easier, or how we could make it easier for a potential buyer to contact you with interest. As always, user feedback is very appreciated—I pay close attention to what folks are suggesting (this one came directly from a conversation with a user).

So please, keep the feedback coming and reach out at any time—I'm excited to see how people use this!
