what is the best accounting software for amazon sellers

What 'Best' Actually Means for an Amazon Seller

Regular retail accounting assumes one sale equals one deposit equals one line of revenue. Amazon breaks that assumption completely. A single settlement period can contain thousands of individual transaction types: product sales, FBA fulfillment fees, referral fees, storage fees, long-term storage surcharges, refunds, returns, chargebacks, promotional discounts, advertising spend, and reserve holds. Software that can't decode that mess isn't accounting software for your Amazon business, it's just a bank feed with a nicer dashboard.

'Best' also depends heavily on where you are. A seller doing $8,000 a month on Amazon only has very different needs than one doing $400,000 a month across Amazon, Shopify, and eBay. The right answer for a single-channel side hustle (a simple general ledger, maybe even a well-built spreadsheet) is the wrong answer for a multi-channel operation that needs proper ecommerce accounting, accurate cost of goods sold by SKU, and clean books for a lender or buyer.

How Amazon Accounting Software Actually Works

Under the hood, real Amazon accounting software does three things a generic bookkeeping app can't do on its own. First, it pulls your settlement reports (or the underlying transaction-level data) directly from Amazon via API. Second, it categorizes every line item into the right bucket: gross sales, Amazon fees, FBA fees, refunds, advertising, sales tax collected, and reserves. Third, it posts a summarized journal entry into your general ledger, usually one entry per settlement period, so your books match what actually happened rather than just what hit your bank account.

This matters because more than half of everything sold on Amazon comes from third-party sellers, not Amazon retail itself, which is exactly why Amazon built such a complex settlement and fee structure in the first place. Per Amazon's own investor disclosures, third-party sellers account for more than half of the physical gross merchandise sold on the platform, and every one of those sellers is running through the same fee and reserve mechanics your books need to capture correctly.

• •Gross product sales (before any deductions)
• •Amazon referral fees and FBA fulfillment fees
• •Storage fees and long-term storage surcharges
• •Refunds, returns, and chargebacks
• •Advertising spend (Sponsored Products, Sponsored Brands)
• •Sales tax collected and remitted by Amazon as marketplace facilitator
• •Reserve holds and releases

QuickBooks, Xero, or an Amazon-Specific Tool: What's the Real Difference

QuickBooks Online and Xero are general ledgers. They're built to handle bank reconciliation, invoicing, payroll, and tax reporting for any business, and they're genuinely good at that job. What they aren't built to do is understand an Amazon settlement report out of the box. If you connect your bank account directly to QuickBooks and let it auto-categorize Amazon deposits, it'll usually just book the net deposit as 'Amazon income,' which buries your real revenue, real fees, and real COGS inside one lump number.

This is where a dedicated connector earns its keep. Tools purpose-built for Amazon accounting software that syncs to QuickBooks & Xero sit between Amazon and your ledger, pulling the settlement data, splitting it into the right categories, and posting clean summary entries so QuickBooks or Xero ends up with accurate books instead of a mystery deposit. BeanHawk is one example of this category, built specifically for sellers who need FBA reimbursement tracking alongside their books, not just journal entries. The choice between QuickBooks for Amazon sellers and Xero for Amazon sellers usually comes down to preference and existing accountant relationships; both work fine as the ledger of record once a connector is feeding them properly.

A Worked Example: One Settlement Period

Say a seller's two-week Amazon settlement shows gross product sales of $42,000. Amazon fees for that period (referral fees plus FBA fulfillment) come to roughly $9,800, hypothetically. Customer refunds total $1,200, and the seller ran $2,100 in Sponsored Products ads billed through the same account. Net of all that, Amazon deposits $28,900 into the seller's bank account.

A bank-feed approach records exactly one thing: $28,900 of income. That's it. There's no COGS, no visibility into ad spend as a marketing expense, no separate refund line, and no way to calculate true gross margin per unit. Software connected properly to the settlement data instead books gross sales of $42,000, Amazon fees of $9,800, refunds of $1,200, and advertising of $2,100 as separate line items, netting to the same $28,900 cash deposit but giving you a real income statement. Add cost of goods sold on top of that (say $14,000 for the units actually sold in the period, tracked separately through inventory accounting) and you finally see your real margin, not just your bank balance.

Sales Tax and 1099-K: Why Bookkeeping Software Alone Won't Save You

Sales tax is where a lot of sellers assume Amazon handles everything, and mostly they're right, but 'mostly' is the operative word. Since the Supreme Court's 2018 ruling, states have been allowed to require out-of-state sellers to collect sales tax based on economic nexus (crossing a sales or transaction threshold) rather than needing a physical presence in the state, per the Supreme Court's decision in South Dakota v. Wayfair. That ruling is why nearly every state with a sales tax now has marketplace facilitator laws requiring platforms like Amazon to collect and remit tax on third-party sales automatically, as tracked by the Sales Tax Institute. Good accounting software still needs to record that collected and remitted tax correctly on your books, even though Amazon is doing the actual remitting, because it flows through your settlement reports as both a collection and a payout.

The other piece is 1099-K reporting. The old $20,000-and-200-transaction threshold has been phased down in recent years rather than staying fixed, according to the IRS's own guidance on Form 1099-K, which means more sellers are getting these forms than in past years, sometimes at revenue levels that catch part-time sellers off guard. Your accounting software won't file the 1099-K for you (Amazon does that), but it needs to produce books that reconcile against whatever number shows up on that form, or you'll spend tax season explaining a discrepancy to your accountant instead of running your business.

FBA Reimbursements Are an Accounting Problem, Not Just an Ops Problem

Most sellers think of lost or damaged FBA inventory as a warehouse problem: Amazon lost a pallet, file a case, get reimbursed, move on. But since 2025, Amazon reimburses lost or damaged inventory based on the seller's actual manufacturing or sourcing cost, using Amazon's own estimate unless the seller has submitted their real cost, according to Amazon's FBA inventory reimbursement policy. If your accounting software isn't tracking accurate landed cost per SKU, you have no basis to dispute an underpaid reimbursement, and you'll likely just accept whatever Amazon's default estimate happens to be, which is usually lower than your real cost.

This is the part general ledgers and even most Amazon connectors don't handle well: matching reimbursement income against the inventory loss it's supposed to cover, and flagging when a reimbursement looks short. It's a narrow but expensive gap, and it's a big reason accurate, SKU-level cost data belongs in your accounting stack from day one rather than something you reconstruct after the fact when a case gets denied.

Common Mistakes Sellers Make With Amazon Accounting Software

The most common mistake is treating the Amazon deposit as revenue instead of breaking it into gross sales, fees, refunds, and ad spend. It inflates margin on paper and hides the fact that fees might be eating a bigger share of sales than last year. The second most common mistake is running cash-basis accounting once you're selling across multiple channels; cash basis can work for a single-channel Amazon-only seller doing modest volume, but it falls apart fast once you add Shopify or eBay accounting software into the mix and need consistent inventory valuation across channels.

A third mistake is not separating personal and business finances early, which makes every later step, tax filing, applying for financing, or preparing for due diligence, harder than it needs to be. And a fourth is picking software based on price alone and ending up with a tool that can connect Amazon to QuickBooks but can't handle eBay or Shopify at the same time, forcing a rebuild in a year.

• •Booking net Amazon deposits as revenue instead of splitting out fees and refunds
• •Using cash-basis accounting once you're multi-channel or holding real inventory
• •Mixing personal and business bank accounts and cards
• •Choosing a tool that only supports Amazon when you're already selling on Shopify or eBay too
• •Ignoring landed cost per SKU, which weakens both margin analysis and reimbursement claims

What to Do Next: Building the Right Stack

Start with your ledger. If you don't already have QuickBooks Online or Xero set up, pick one; either handles tax filing, bank reconciliation, and reporting fine, and the choice is more about your accountant's preference than any technical limitation. Then layer an Amazon-specific connector on top that can parse settlement reports into real categories and, ideally, track inventory cost and reimbursements at the same time, since that's the part generic tools skip entirely.

If you're selling on more than just Amazon, make sure whatever you pick can also connect Shopify or eBay to the same ledger, so you're not maintaining three separate sets of books that never quite agree with each other. And if FBA reimbursements are a meaningful part of your bottom line (they usually are for anyone running real inventory volume), make sure your software ties cost data to those reimbursement claims instead of treating them as a random deposit that shows up once a month.
