When a supplier asks for a deposit or prepayment, the proforma invoice usually lands in someone's inbox — and everything after that happens over email: forward it to whoever pays, re-key the wire details into the bank, then remember to send proof back. Details get lost, nobody can say who approved a five-figure wire or against which PO, and swapped bank details in an intercepted email thread are the classic way overseas payments get stolen. Vendor Deposit Payments pulls the whole flow into SKU — record the supplier's proforma invoice against a purchase order, request payment from a designated payer with the wire instructions attached, capture the payment proof, and email the supplier a remittance advice — with every step on the record.

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.

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.

Landed cost bills used to live scattered across the documents they belonged to. A freight invoice was tucked inside its purchase order, a customs bill inside another, an insurance premium inside an inbound shipment — and the only way to answer "which bills haven't been applied to my product costs yet?" was to open every document one by one. Landed Cost Bills is a new register that brings every bill together in a single searchable table, with live totals and an allocation status on every row, so a bill that hasn't reached your landed costs can't go unnoticed.

When a supplier issues a credit memo — a short shipment, transit damage, a price adjustment — someone has to key it into SKU line by line, and the PDF itself ends up buried in an inbox or a shared drive. Vendor Credit OCR & Document Attachments ends both problems: attach the credit memo straight to the vendor credit for a permanent audit trail, or upload it and let AI read it for you. SKU extracts the supplier, credit number, date, line items, and totals, matches each line to your products, and pre-fills a vendor credit you review and confirm — turning five to ten minutes of data entry into under two. And credit memos that arrive by email need no upload at all: the Document Inbox now recognizes them automatically and routes them straight to the credit memo review queue.

Filing a state sales-tax return used to mean leaving SKU.io, exporting orders, and rebuilding the numbers in a spreadsheet — channel by channel, because each marketplace only shows you its own slice. Sales Tax Reporting brings the whole picture into one place: tax collected by destination state, the split between what you owe and what your marketplaces already remitted for you, and a live view of where you're approaching economic-nexus thresholds.

If you've ever re-run the Inventory Valuation report "as of" a closed month and gotten a different number than last time, you know how unsettling that is — especially at month-end close. It happened because cost corrections (a late freight bill, a vendor invoice true-up, a write-down) silently rewrote history: the report always valued past inventory at today's cost. With Inventory Revaluations, every cost change is now a dated, auditable event. The valuation report values each period at the cost that was in effect on that date, so the same as-of date returns the same value — no matter what corrections land later.

If you make or assemble what you sell, you've been stitching the production side together by hand — drawing down raw-material stock in one place, adding finished units in another, and working out what each batch actually cost in a spreadsheet. SKU now does all of it for you. Manufacturing lets you define a recipe once, run a manufacturing order to turn components into finished goods, and have SKU consume the raw materials, receive the finished product into stock, and post the accounting — automatically, every time you produce.

When a customer has a store credit on file and a sales order they haven't paid yet, the obvious thing to do is use one to settle the other. Until now that took several manual steps — recording a fake payment, remembering to mark the credit as used, and reconciling both sides by hand. Applying Store Credit to Sales Orders turns that into a two-click flow: open the order's Payments tab, pick the credits to apply, and SKU records the allocation, updates the order's balance, and keeps the credit's remaining balance in sync — all in one go.
