Every business has that one question the standard reports can't quite answer — "on-hand value by product this month", "revenue by channel and brand", "which SKUs are moving and what are they worth". Until now, answering it meant exporting to a spreadsheet or asking someone to build a report for you. The new Custom Report Builder lets you answer those questions yourself: pick the data, drag the fields you care about, and get a live table, chart, or pivot in seconds — no spreadsheets, no waiting.

If you sell supplements, food, cosmetics, pet products, or anything else with a shelf life, you need to know exactly which batch is on the shelf, when it expires, and whether you're shipping the soonest-to-expire stock first. Until now SKU could only capture that detail inside manufacturing. Lot & Expiry Tracking brings batch numbers and expiration dates to the entire platform — capture them when you receive, pick the right lots automatically, and see what's expiring (and what it's worth) before it becomes a problem.

Quoting a customer used to mean creating a sales order, flagging it as a quote, and then remembering to filter those quotes back out of every list, total, and report. There was no real quote lifecycle, no clean way to track what you'd sent, and "converting" a quote to an order was a flag flip that could quietly let the price drift before the order was worked. Quotes are now a first-class part of SKU.io — with their own workspace, their own status lifecycle, a branded quote document, and a one-click, price-locked conversion to a sales order.

Sending an FBA replenishment through a 3PL or supplier has always meant a scramble of emails — FNSKU labels in one attachment, box-content rules in another, prep instructions pasted into a note, and a separate back-and-forth just to confirm anything actually shipped. FBA Inbound for 3PLs & Suppliers replaces all of that with one clean handoff. When an inbound plan is sourced from a 3PL warehouse or a supplier, SKU.io packages everything the recipient needs into a single branded portal and emails them the link. And when a line is a kit your 3PL still has to assemble, SKU.io spells out exactly what to build and allocates the components so you can't oversell them.

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.

Your gross margin says a product is profitable. But after the ad spend, the affiliate payouts, the warehouse rent, and the software subscriptions — is it? Those indirect costs live in invoices and spreadsheets, never connected to the products that caused them. Cost Allocation closes that gap: record any indirect cost in SKU.io, spread it across the products, brands, suppliers, or sales channels it belongs to, and see true contribution margin — revenue minus COGS minus the overhead each product actually carries. It's a profitability layer, not a bookkeeping one: allocations never create accounting transactions, so there's no risk of double-counting against your real books.

"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.
