How do I account for Amazon advertising costs in my books?
Amazon advertising costs should be recorded as a marketing or advertising expense, separate from your cost of goods and Amazon seller fees. The accounting treatment is simple. The challenge is extracting clean data from Amazon’s consolidated reporting.
Amazon deducts advertising costs from your settlements before depositing funds to your bank account. The net deposit you see is already reduced by ad spend, referral fees, FBA charges, and everything else Amazon takes out. If you just record the bank deposit as revenue, you’re understating both your sales and your advertising expenses. Your books will balance but they won’t tell you anything useful about how much you’re actually spending to acquire customers.
Pull your advertising reports directly from Amazon’s advertising console rather than relying solely on settlement reports. The console gives you detailed breakdowns by campaign, ad type, and time period. This granularity helps you understand what’s working and where you’re wasting money. Settlement reports lump everything together in a way that makes analysis nearly impossible.
In your chart of accounts, create an advertising or marketing expense account specifically for Amazon ads. Don’t combine this with Amazon’s selling fees or referral commissions. Ad spend is a discretionary cost you control. Referral fees and FBA charges are direct costs of selling on the platform. Keeping them separate lets you see true product margin versus marketing investment at a glance.
If you’re running significant e-commerce volume through Amazon, consider integration tools like A2X or Link My Books. These connect to your Amazon account and automatically break out advertising costs, fees, refunds, and net revenue into your accounting software. The time savings add up quickly and the data is more reliable than manual extraction from multiple Amazon reports.
Track your advertising as a percentage of revenue each month. If you’re spending 30% of revenue on advertising but your product margins are 25%, you’re losing money on every advertised sale. Good small business bookkeeping makes this obvious before it becomes a serious problem. The goal isn’t just recording the expense correctly. It’s having numbers that actually help you make better decisions about where to put your ad dollars.

What is A2X and do I need it for my Amazon accounting?
A2X is software that automatically pulls Amazon settlement data into your accounting software, breaking out sales, fees, refunds, and FBA charges. You probably need it once you're doing consistent volume and want accurate financials.
Read answerWhy is my e-commerce profit and loss statement inaccurate?
E-commerce P&Ls are often wrong because of inventory costing problems, miscategorized marketplace fees, or timing issues with returns. The most common culprit is Cost of Goods Sold that doesn't reflect actual product costs including landed costs like shipping and duties.
Read answerDo I need FIFO or LIFO for my retail inventory?
For most retail businesses, FIFO is the better choice. It matches how inventory actually moves through your store and keeps your balance sheet accurate. LIFO creates complexity that rarely benefits smaller retail operations.
Read answerHow do I track returns and chargebacks for my online store?
Record returns as revenue reductions and chargebacks as disputed transactions with their associated fees. Keep them in separate accounts so you can see patterns and understand your actual margins.
Read answerWhat financial reports should a DTC brand review monthly?
DTC brands need a P&L structured to show contribution margin, a cash flow report to track timing gaps between spending and collecting, and inventory reports that identify slow movers. Standard reports work, but the structure matters.
Read answerWhat accounting method should I use for my Shopify store?
Most small Shopify stores can legally use cash basis accounting, but accrual often makes more sense once you're carrying inventory. Cash is simpler for tax prep, but accrual shows actual profitability by matching product costs to the revenue they generate.
