Bookkeeping for Best Buy Marketplace Sellers: Weekly Settlements, Commission on Shipping, Store-Return Freight, Reserves and 1099-K
Best Buy Marketplace invoices weekly and pays 14 days later, net. Book revenue gross, then record commission (including the shipping portion), the $29.99 platform fee, ads, return label freight, chargebacks and reserves separately; sales tax and recycling fees Best Buy collects aren't revenue; reconcile to the 1099-K at year end.

Best Buy Marketplace invoices sellers weekly and pays 14 days after the invoice, and what lands in your bank is net of commission, the platform fee, ads, refunds, chargebacks and return freight. Your books work the other way: record sales at gross, then record every deduction in its own account; leave out the sales tax and recycling fees Best Buy collects; and treat held reserves as a receivable. Do that and the 1099-K reconciles line by line at year end.
How payouts work
Under Best Buy's seller standard terms and program policies, customer payments are routed by Best Buy's payment partners into accounts held for the benefit of Best Buy and the seller. Seller payments are invoiced weekly for completed orders and paid 14 days after the invoice by EFT to the bank account registered with the payment provider. Deductions tied to the original order, such as refunds, card chargebacks and return freight, are taken immediately. Sellers must send the advance shipment notice or order status; Best Buy isn't obliged to pay for orders without it.
If you disagree with a deduction, file a dispute through the Seller Hub within 60 days of the payment date; Best Buy aims to resolve it within 30 days and pays any amount due on the next regular payment. Payments not disputed within 60 days are final.
How to book each item
Sales: item price plus the shipping you charge customers is revenue, recorded gross. Sales tax, California's e-waste and battery-embedded fees and other fees Best Buy collects are not your revenue; if the settlement report shows them, split them out.
Commission: Best Buy charges commission as the category rate times item price plus shipping, with rates from 8% to 15% by category (Seller Hub table, September 15, 2026). Orders where you charge shipping pay commission on the shipping too, so book commission from the settlement's actual figures rather than estimating from price.
Platform fee: $29.99 a month per store, billed monthly once the first sale happens; book it as a platform fee, one per store.
Ads: Best Buy Ads self-service spend is deducted from your seller account; keep it in its own advertising account so you can measure return on spend.
Returns: customer returns reduce revenue. Online returns ship back on a prepaid Best Buy label, with freight deducted from your payout. For store returns, the store refunds the customer and ships the item back to your warehouse on Best Buy's carrier account, again at your cost. Book that freight as return shipping expense, separate from the revenue reversal. Resalable units go back to inventory; the rest are written off.
Commission doesn't always come back: if you give a partial refund outside policy, or leave a return unprocessed so that Best Buy refunds the customer, Best Buy may keep the commission. Check each return line on the settlement for a commission reversal.
Chargebacks: Best Buy generally carries card-fraud chargebacks; non-fraud chargebacks, for example a customer claiming non-delivery when you can't produce proof of delivery within 2 business days, come out of your payout. Book them as revenue reversals or bad debt depending on their nature, and reverse them if a dispute succeeds.
Reserves: Best Buy may hold back part of your payouts as a reserve against future warranty and indemnity liabilities, or hold payments during an investigation. The money is still yours: book it as a receivable from Best Buy, not an expense, and move it to cash when released.
Warranty: Best Buy requires at least a one-year warranty on new products with electrical or mechanical parts. Book repairs, replacements and shipping as warranty expense when incurred; for larger programs your financial statements may accrue an estimated warranty liability, but for tax the deduction generally comes when the cost is incurred.
3PL costs: Best Buy provides no storage, so sellers ship from their own warehouse or a 3PL. Book receiving, storage, pick-pack and delivery from monthly warehouse bills; delivery is a selling expense, storage an operating expense, and inbound freight and duties before the warehouse go into inventory cost.
Reconciling the 1099-K
As marketplace facilitator, Best Buy issues Form 1099-K by January 31 to sellers over the threshold: more than $20,000 and more than 200 transactions in the year federally (restored retroactively by OBBBA in July 2025), with lower thresholds in some states. The 1099-K reports gross amounts, generally including shipping, before commissions, fees and returns. The IRS instructions say the reported amount isn't reduced for refunds, fees and similar adjustments, so a large gap from your net income is normal; what matters is that you can explain it.
Example (hypothetical numbers, to show the method): a seller's Best Buy orders total $500,000 of item price plus $20,000 of shipping charged, and its 1099-K shows $520,000 gross (use the actual form). The reconciliation runs:
1099-K gross of $520,000, less $31,000 of customer refunds for returns, gives $489,000 of net sales, which is the revenue in the books (gross less returns). Then separately: commission at an assumed average 9% of $520,000, about $46,800, adjusted for reversals per the settlements; platform fees of $29.99 × 12 = $359.88; Best Buy Ads of $26,000; return freight of $6,200; non-fraud chargebacks of $1,500; and an $8,000 reserve balance at year end booked as a receivable.
Every line traces back to a weekly settlement. If the platform's gross figure includes collected sales tax or recycling fees, add a line removing them as well.
Every week
Download settlements and order reports after each invoice and match them to the bank deposit 14 days later. Check deductions for return freight that shouldn't be there, commission not reversed and chargebacks, and dispute within 60 days. Update inventory for units shipped, returned and written off. Split by channel: a company selling on Amazon, Walmart and Best Buy keeps one set of books by channel, allocating inventory and 3PL costs by platform.
At year end
Reconcile to the 1099-K and keep the worksheet. Count inventory at quantity and cost, with duties and inbound freight capitalized. Confirm the reserve balance as a receivable. File for your entity: a C corporation files Form 1120 (with Form 5472 if 25% or more foreign-owned), a foreign-owned single-member LLC pro forma 1120 + 5472, an S corporation 1120-S, and a U.S. resident's single-member LLC Schedule C.

Questions this article answers
How often does Best Buy Marketplace pay sellers?
Under the seller standard terms, payments are invoiced weekly for completed orders and paid 14 days after the invoice by EFT to the seller's registered bank account. Refunds, card chargebacks and return freight are deducted immediately, and Best Buy can hold a reserve or withhold payments during an investigation.
Does Best Buy charge commission on shipping?
Yes. The program policies calculate commission as the category rate times item price plus the shipping you charge, with rates from 8% to 15% by category. Free-shipping listings pay commission on price only. Book commission from the actual settlement figures.
Who pays when a customer returns a marketplace item at a Best Buy store?
The store refunds the customer and ships the item back to the seller on Best Buy's carrier account, with the freight deducted from the seller's payout. The seller processes the return within 1 business day of receipt; large items can't be returned in stores. Book the refund as a revenue reversal and the freight as return shipping expense.
My Best Buy 1099-K doesn't match my income. What should I do?
That's normal: the 1099-K is gross, generally including shipping, before commissions, fees and returns. Reconcile from the 1099-K gross, subtract refunds to get net sales, then list commissions, platform fees, ads, return freight and chargebacks separately, each traceable to a settlement.
