If you fulfill through Walmart Fulfillment Services (WFS), the stock Walmart holds for you has always been a blind spot in SKU — you had to jump back into Seller Center to see quantities, plan replenishment, and put together an inbound shipment. Walmart Fulfillment Services support closes that gap: turn it on for your Walmart integration and SKU gives you a live view of your WFS inventory, a guided workflow to build and send inbound shipments, and end-to-end tracking of those shipments into Walmart's fulfillment centers.

Advertising is usually an Amazon seller's biggest variable cost after the product itself — but until now it lived in a separate tab, invisible to your profitability inside SKU.io. A product could look healthy on margin while quietly losing money once ad spend was counted, and the only way to see the truth was exporting ad reports and inventory reports and joining them by hand in a spreadsheet. Amazon Ads cost attribution closes that gap: connect your Amazon Advertising account and SKU.io automatically pulls your Sponsored Products spend, attributes it to the exact SKU it was spent on, and turns it into real product-level costs — so your contribution margin and ACoS finally include the cost of the ads that drove the sales.

Building an FBA shipment used to mean bouncing between SKU.io, a spreadsheet, and Seller Central — figure out what to send, create a plan in SKU.io, then leave to do packing, placement, carriers, and labels by hand. The most error-prone steps happened outside your system of record, and a multi-SKU shipment could eat an afternoon.

Now you can run the entire Amazon FBA inbound workflow inside SKU.io — from "what should I send?" all the way to "tracking numbers submitted, labels printed." Smart item selection, box content, placement-fee comparison, carrier booking, label printing, and receiving reconciliation are all in one guided flow.

If you sell on Amazon FBA, storage fees quietly eat into your margins — and until now they were invisible at the product level. Amazon charges them per product, per month, but the only way to see what each product was really costing you was to download a TSV, aggregate hundreds of FNSKUs across fulfillment centers, map them to your products, and hand-enter the totals. Every month. So in practice, nobody did. Amazon storage fee cost allocation changes that: SKU.io now pulls Amazon's two storage fee reports automatically and turns them into per-product cost entries — no spreadsheets, no manual entry.

"If I sell this at $X on Amazon, what do I actually keep?" Until now, answering that meant a spreadsheet — one that doesn't know your real landed costs, your channel's fee schedule, or what actually happened the last hundred times you sold the item. Product Pro Forma is a live, per-channel profitability calculator built into SKU.io. Pick any product (or sketch a hypothetical one you're thinking of sourcing), and it models the full unit economics — selling price, COGS with cost-category breakdown, shipping, marketplace fees, payment fees — for each of your connected sales channels. Every input recalculates the results instantly, and for products you already sell, the estimate sits right next to your actual realized profitability so you can see exactly where your assumptions drift from reality.

Keeping your catalog, inventory, and orders in sync has always meant repetitive busywork: downloading a supplier's price file, massaging the columns, importing it, and doing it all again next week — or asking for custom development every time a partner sends data a slightly different way. Workflows changes that. It's a visual automation builder inside SKU.io where you chain a trigger to a series of actions on a drag-and-drop canvas: when a file lands on an FTP server, when a schedule fires, or when something happens in SKU itself, your workflow picks the data up, transforms it, and writes it into your account — no spreadsheets, no waiting on engineering.

Chasing payment on an order has always meant leaving SKU.io — copying an amount into a separate payment tool, emailing a link by hand, then circling back to mark the order paid once the money landed. It's slow, easy to forget, and the two systems never quite agree.

Stripe Payments closes that loop. Connect your Stripe account once, and you can send a customer a secure, hosted invoice directly from any sales order. Your customer pays with a card through Stripe's checkout, and SKU.io records the payment against the order automatically — no manual reconciliation, no copy-paste, no guesswork.

If you've connected a script, a custom integration, or an automation tool to SKU with a personal access token, that token has been a black box: is it still being used? Is it failing? Is it slow? And — the question that really matters — is it being used from somewhere it shouldn't be? API Usage Log answers all of that. Every API request made with a personal access token is now recorded automatically, and each token gets its own analytics dashboard and a searchable, filterable log of every single request.

If you run Amazon in SKU.io, your day moves across a lot of pages — orders, FBA inventory, removal orders, reimbursements, settlements, reports. Until now those pages didn't all look or behave the same way, so a single workflow could feel like using two different products: different navigation, different tables, different filters. We've rebuilt the entire Amazon integration into one modern, consistent workspace. Every page now shares the same layout, the same powerful filtering and saved views, the same exports and bulk actions — and a single view across all your Amazon accounts.

If you sell on more than one channel, you already know the problem: to check a listing you had to find its product first, open it, and dig into the Listings tab — one product at a time. There was no way to ask "show me every Amazon listing" or "which channels are out of sync with my real stock?" without clicking through your whole catalog. The new Listings and Channel Inventory pages fix that. They give you a single table of every listing across every connected channel — and a dedicated view that shows, at a glance, exactly where each channel's stock has drifted from SKU.io and lets you correct it in bulk.
