What SKU.io posts to your client's books, and how you check it

What SKU.io posts, and when

SKU.io keeps its own double-entry ledger, written from the documents the business already creates. Nobody types journal entries. If a document changes after its entry has posted, SKU.io posts a correcting entry. It never edits the old one. A deleted document's entry is reversed, not erased. High-volume postings such as shipments can be batched into one summary entry per period and per sales channel, so the provider does not fill up with a line for every order.

Event	What posts	When
A sale on a payout channel	Booked once, from the payout. The order keeps its invoice for the record, but that invoice posts nothing and is not sent to Xero or QuickBooks. Payout channels and order invoices	When the payout or settlement arrives
A sale invoiced on its own (wholesale, or a channel set per order)	Debit Accounts Receivable. Credit Sales and Sales Tax. How automatic accounting works	When the order is invoiced
A shipment	Debit Cost of Goods Sold, credit Inventory Control, at the first in, first out (FIFO) cost of the units shipped, including any landed cost recorded against them. FIFO layers and COGS	When the shipment goes out
Stock received on a purchase order, then the supplier bill	Receipt: debit Inventory Control, credit Accrued Purchases. Bill: debit Accrued Purchases, credit Accounts Payable. How automatic accounting works	On receipt, then on the bill
Stock lost, damaged or expired	Shrinkage, lost and stolen go to Inventory Shrinkage. Damaged goes to Inventory Damage Write-Offs. Expired goes to Expired Stock Write-Off. Counting mistakes and losses with no reason go to COGS. Send inventory losses to their own accounts	When the loss is recorded, from the day the accounts are mapped
Tax a marketplace collects and remits	Posts twice to a separate Marketplace Facilitator Tax account, once collected and once remitted, so it nets to zero and stays out of Sales Tax. Tax the seller collects itself still posts to Sales Tax. Account for marketplace facilitator tax	By order date, from the day it is adopted
A payout that spans two months	One part per month. Earlier parts are dated the last day of their month, and the parts still add up to the one deposit. Split settlements at month end	Month end
A bill from a supplier in another currency (optional)	Posts in the supplier's currency at the bill-date rate, so Xero or QuickBooks books the realized exchange gain or loss when it is paid. Post supplier bills in their own currency	On the bill

Payout channels

On Amazon, Shopify, eBay, Walmart, TikTok Shop and Temu, a channel set to "Per payout" books each sale once, from the payout, so the sale is not counted twice and the order's receivable does not sit open. Amazon channels start on Per payout. So do Shopify stores connected now. A month-end check fails while any order invoice on a payout channel still carries a receivable its payout already booked.

• Walmart: One sales invoice and one fee bill per settlement, adding up to the deposit to the cent, from Walmart's reconciliation report. Guide
• TikTok Shop: One sales invoice and one fee bill per payout, equal to the deposit to the cent. The reserve and any negative balance sit in a balance-sheet clearing account. Guide
• Temu: Each statement posts as an invoice equal to the deposit, with "Others" on a separate fee bill and the rolling reserve in a balance-sheet account. Temu has no payout API, so statements come from two files downloaded from Temu Seller Center, or are typed in. Guide
• Shopify and eBay: Each payout posts as invoices and bills whose net equals the deposit. Lines can also be split into product, shipping, discount and tax, which sends buyer-paid tax to Sales Tax, never revenue. Guide
• Amazon: Settlements map to your accounts, and each settlement shows whether Amazon actually paid it out. A month-end check flags any that were not deposited. Guide

Payout mappings are dated. A change starts on a date you choose, earlier payouts keep the accounts they posted with, and payouts on or before the hard close date are never rebuilt (change payout mappings from a date).

Revenue timing

Revenue is booked on the order date by default. For sellers who need revenue to wait for the shipment, such as pre-orders, long lead times or ASC 606 reporting, there is an optional "At fulfillment" basis. Revenue moves to Sales as each shipment goes out, in the same entry as its COGS. On payout channels this covers Amazon, eBay, Shopify and Walmart, not TikTok Shop or Temu. You can preview it month by month on the client's own recent orders before switching, and orders created before the switch date keep order-date recognition (revenue recognition at fulfillment).

The chart and the channel split

New accounts start with an ecommerce chart of accounts. An existing account can apply the same standard after a full preview, and it only adds what is missing: nothing already set is remapped, renamed or deleted, and nothing is written in a locked period. Marketplace and payment processing fees sit in cost of sales, above gross margin. Advertising stays an operating expense (release note). Channels are told apart with a Xero tracking category or QuickBooks classes on revenue, COGS, marketplace fees and FBA inventory, instead of a longer chart (tag entries by channel). Account rules by category, brand, supplier or product type send each product's sales and costs to the right accounts, new products included (map product accounts with rules).
