Amazon FBA Accounting & Bookkeeping 2026: Fees, Settlements, Channel P&L

You’re selling $3M on Amazon. Your biweekly deposits hit the bank. Your bookkeeper records them as “sales.” And you have absolutely no idea whether you’re making money.

That’s the default state of Amazon FBA accounting and Amazon FBA bookkeeping for most brands — and it’s a ticking time bomb.

I’ve seen it dozens of times across the brands we work with at Eightx. A founder pulls up their P&L, points to the revenue number, and feels good about it. But when we decompose those Amazon settlements into their actual components — gross sales, referral fees, fulfillment fees, storage charges, advertising spend, refunds, reimbursements — the picture changes dramatically. Sometimes a brand that thought it was making 20% margin on Amazon is actually making 5%. Or losing money entirely.

At Eightx, we’ve managed Amazon FBA bookkeeping and FBA accounting for brands from $2M to $130M across Amazon US, Canada, UK, EU, and Australia. The pattern is consistent: Amazon obscures your financial data behind bundled settlements, and most bookkeepers don’t know how to untangle it. This guide covers everything we’ve learned about doing it right — whether your team calls it Amazon FBA accounting, Amazon FBA bookkeeping, or both.

Amazon FBA accounting and Amazon FBA bookkeeping describe the same workflow at different levels: bookkeeping records each transaction (settlement decomposition, fee categorization, reimbursement tracking), and accounting closes the books, prepares financials, and produces channel-level P&Ls. Both involve breaking Amazon’s bundled bi-weekly settlement deposits into their component parts — gross sales, referral fees, fulfillment fees, storage fees, advertising costs, refunds, and reimbursements — and recording each in the correct line item. Unlike standard eCommerce accounting where you control the data flow, FBA bookkeeping requires reconciling Amazon’s reports against your bank deposits to achieve true financial visibility.

Why Amazon FBA Accounting Is Uniquely Complex

If you’re running a Shopify store, your accounting is relatively straightforward — especially with proper ecommerce bookkeeping built for multi-channel in place. Shopify is your source of truth for gross sales, discounts, net sales, and shipping. The data flows cleanly into your books.

Amazon is a different animal.

Everything comes bundled. Amazon batches all transactions into bi-weekly deposits. Each settlement combines gross sales, multiple fee types, refunds, reimbursements, and balance adjustments into a single net deposit. If your bookkeeper is recording that deposit as “sales” — and many do — you’ve lost visibility into every line item that matters.

We took on a client where the previous bookkeeping firm was doing exactly this. The biweekly Amazon payment was booked as sales, nothing else. No journal entry for the underlying reports. None of the advertising fees were captured. None of the FBA fees. The bookkeeper literally just recorded the net deposit. Wrong, wrong, wrong.

Amazon is always holding your money. At any given time, Amazon has roughly two weeks of your revenue sitting in their accounts. That creates a deposits-in-transit balance that needs to be tracked as a receivable. If nobody reconciles it, that balance can grow unchecked. At one of our clients, we found $500K in unresolved Amazon deposits-in-transit. Half a million dollars sitting in limbo because nobody was pulling the settlement reports and reconciling against the bank.

The data doesn’t always match. One of our clients — a green cleaning products company doing $60M+ — found that Amazon reports “don’t match, typically 20% up or down” compared to internal records. That’s not a rounding error. That’s a systemic reconciliation challenge that requires robust processes and regular cross-checking between Amazon’s business reports, settlement reports, and your bank reconciliation.

Timing mismatches compound the problem. Under accrual accounting, customer orders, Amazon shipments, and fee calculations all occur on different dates. Revenue recognition, fee accrual, and cash receipt don’t align neatly — which means your monthly close requires careful attention to cut-off dates and period-end adjustments.

Amazon Fee Structure — Where Every Dollar Goes on Your P&L

The Fee Categories Every FBA Seller Must Track

Amazon’s fee structure has grown more complex every year. FBA fees increased roughly 30% over the past two years, with 2026 bringing another average increase of $0.08 per unit on fulfillment fees. Here’s what you need to track:

• Referral fees (8–15% depending on category, up to 45% in some): Amazon’s commission on every sale
• FBA fulfillment fees (variable by size and weight): Picking, packing, and shipping each unit — ranges from under $4 for small standard-size to $10+ for large items
• Monthly storage fees (per cubic foot): Charged for inventory sitting in Amazon warehouses
• Long-term / aged inventory surcharges: Items stored 271–365+ days incur penalties ($0.15–$0.30/unit/month, rising to $0.35/unit or $7.90/cubic foot at 15+ months)
• Low-inventory-level fees: $0.32–$2.09 per unit if supply drops below 28 days at the FNSKU level
• Inbound placement fees: Charges for shipping to multiple fulfillment centers
• Advertising costs (PPC): Typically 20–40% of ad-generated sales measured as ACOS
• Removal and disposal fees: Charges for pulling or destroying unsold inventory

Where Amazon Fees Should NOT Go — The COGS Mistake

This is one of the most important accounting decisions for any Amazon seller, and most get it wrong.

Do not put Amazon fees in COGS. It obscures your data.

Here’s why: your gross margin should be comparable across channels. If you’re selling the same product on Amazon and Shopify, and the selling price less discounts is similar, your gross margins should be nearly identical. Product cost is product cost. But your contribution margin — the net you keep after all variable expenses — will diverge dramatically because Amazon takes 25–40% in fees while Shopify takes only 2.9% + $0.30.

If your bookkeeping company is lumping Amazon fees into COGS alongside product costs, ask them to stop. Not only because it obscures your internal data, but because when you go to sell your business or raise capital, investors look at gross margin first. If yours looks artificially low because Amazon fees are buried in COGS, the first question is “what’s going on here?” That confusion costs you time during due diligence — time you don’t have.

We worked with a pet care CPG brand that sold through retail (Petco, TJX/HomeGoods), DTC, and Amazon simultaneously. When Big Four firms came in for financial due diligence ahead of a potential sale, clean channel-level financials were non-negotiable. If those Amazon fees had been mixed into COGS, the entire gross margin story would have been muddled. The brand also had negative inventory balances and deposits-in-transit issues that needed resolution — all of which start with getting the chart of accounts right.

Here’s how the fee categories should map to your P&L:

Amazon FBA Bookkeeping Setup: Chart of Accounts & Clearing Accounts

Before you can reconcile anything, your chart of accounts needs to support the complexity of Amazon FBA. Here’s what most bookkeepers miss.

Revenue accounts: You need separate revenue accounts (or at minimum, sub-accounts) for Amazon and Shopify. If you’re on multiple Amazon marketplaces, consider sub-accounts per marketplace (Amazon US, Amazon CA, Amazon UK). This makes channel-level reporting possible without custom queries.

Amazon clearing account: This is critical. When Amazon sends a settlement, the net deposit hits your bank. But the gross sales, fees, and refunds that compose that deposit need somewhere to flow through. A clearing account acts as the intermediary — each component of the settlement is posted to the clearing account, and the net clears to cash. When done correctly, the clearing account balance should be near zero after each settlement is processed. For example, if Amazon settles $50,000 and your clearing account was carrying a $3,200 balance from the prior period, your clearing account should net to $3,200 after posting the new settlement — not grow to $53,200.

If the clearing account isn’t set up right, it builds and builds. You end up with a growing unexplained balance that eventually requires a massive write-off. We’ve seen clearing account balances of $50K–$200K that accumulated over years because nobody understood the reconciliation process.

Deposits-in-transit account: An asset account tracking what Amazon owes you. The balance should approximate two weeks of Amazon revenue at any given time. If it’s significantly higher or lower, something is wrong with your reconciliation.

Fee expense accounts: Separate accounts for referral fees, fulfillment fees, storage fees, and advertising. Don’t lump them together — you need visibility into each fee category to manage costs effectively.

Accrual basis is non-negotiable. If you’re still on cash basis, converting to accrual is the first thing any controller or fractional CFO will do. You cannot make informed decisions about Amazon profitability on cash basis — the timing mismatches between settlements, fee accruals, and inventory purchases make cash-basis financials almost meaningless for an FBA seller.

Settlement Report Reconciliation — The $500K Problem

Let me walk you through how settlement reconciliation should actually work — including the math — because this is where most Amazon sellers’ books go sideways.

What a Real Amazon Settlement Looks Like

Here’s a simplified breakdown of what a $50,000 Amazon deposit actually contains:

If your bookkeeper records $50,000 as “sales,” you’ve just understated your actual revenue by $28,500 and missed $27,255 in expenses and $4,150 in refunds. Your P&L is fiction.

The right way: Each line in that table becomes a journal entry to the appropriate account. Revenue goes to Amazon revenue. Each fee type goes to its specific expense account. Refunds reduce revenue. Reimbursements go to their own income account. The net deposit reconciles to what hit the bank.

The delta between what Amazon owes you (per the settlement report) and what’s in your bank is your deposits-in-transit balance — an asset account reconciled every settlement period. When this isn’t done, it drifts.

At one client, that drift had accumulated to $500K. Half a million dollars of unreconciled deposits-in-transit, sitting as an unexplained balance on the balance sheet. The fix isn’t complicated — it’s just disciplined. Pull the report, credit and debit each component, reconcile to the asset account, verify against the bank. If you’re managing this inside Amazon Seller Central accounting, the reports are all there — the discipline is pulling them consistently.

Amazon FBA Bookkeeping vs Accounting: What’s Actually Different

Sellers and bookkeepers use these terms loosely, but the distinction matters when you’re hiring a contractor or scoping an engagement: Amazon FBA bookkeeping is the weekly mechanical work — pulling settlement reports from Seller Central, decomposing each payout into its component journal entries, reconciling deposits-in-transit, and categorizing every fee correctly. Amazon FBA accounting is the higher-altitude work that depends on clean bookkeeping — closing each month, accruing fees that haven’t hit the bank yet, separating channel P&Ls, calculating channel-level contribution margin, and producing the financials that a CFO, lender, or acquirer can actually use.

A junior or generalist bookkeeper can usually handle Amazon FBA bookkeeping if you give them the right chart of accounts and a clear settlement-decomposition SOP. Amazon FBA accounting almost always needs someone with FBA-specific experience — the deposits-in-transit reconciliation, the multi-marketplace currency handling, the channel-margin disaggregation, and the accrual timing for reimbursements all break in predictable ways the first time a non-specialist tries them.

Amazon FBA Accounting vs Standard eCommerce Accounting

Returns Accounting for Amazon FBA Sellers

Returns on Amazon follow a specific accounting treatment that’s simpler in principle than most people make it — but operationally messy.

The core principle: reverse the sale and put the cost back in inventory at original cost basis.

If a product costs $40 and the customer returns it, you reverse the revenue and put the $40 back into inventory. It’s a net-zero COGS adjustment. The sale unwinds, the inventory restores, and your P&L reflects the reality that no economic transaction completed.

Where it gets more nuanced:

Sellable returns go back into active FBA inventory at original cost. Straightforward.

Non-sellable returns (damaged, opened, customer-damaged) need to be written off as an inventory loss. Industry data suggests roughly 30% of Amazon returns come back in non-sellable condition — that’s a real cost that many sellers aren’t tracking. If you’re doing $5M on Amazon with a 15% rate of returns, and 30% of those returns are unsellable, that’s $225K in potential inventory write-offs annually.

Partial refunds and restocking. Amazon sometimes issues partial refunds (e.g., for items returned without original packaging). The accounting treatment: recognize the partial refund as a reduction in revenue, but if the item goes back into sellable inventory, the cost stays in inventory at original cost basis. Track the difference.

Return shipping costs. When Amazon charges return shipping back to the seller (common for FBA items where the return reason is “no longer needed”), that cost should hit your returns/adjustments expense line — not COGS.

Seasonal spikes. Monitor return rates carefully. Amazon’s return policies are more generous than most DTC brands would choose, and during Q4 the uptick can be dramatic. Brands that sell $10M+ on Amazon often need specialized finance support just to handle the returns accounting complexity during peak season — understanding the sellable vs. non-sellable split directly impacts inventory valuation.

Multi-Marketplace Accounting — US, Canada, UK, EU, and Beyond

If you’re selling on multiple Amazon marketplaces, your accounting complexity multiplies with each one.

One of our clients — a green cleaning products company — was selling across Amazon US, Canada, UK, and Australia, with plans to expand into the EU through a Netherlands subsidiary. They were doing $60M+ in revenue, and the multi-marketplace accounting challenges were significant. Each marketplace introduces its own layer:

Currency. Amazon pays in local currency — USD for US, CAD for Canada, GBP for UK, EUR for EU. If you’re not managing FX conversion carefully, you’re losing 2–4% on every transaction. Use local bank accounts or specialized payment processors (like Airwallex) to collect in local currency and minimize conversion fees. Your accounting integration should handle daily exchange rate conversions to your base reporting currency.

Tax. Each jurisdiction has its own regime. VAT in the UK and EU (with OSS reporting for cross-border sales). Sales tax in the US (nexus-based, varies by state — see our guide to Amazon FBA tax planning). GST/HST in Canada. You remain liable even when Amazon collects and remits on your behalf — your books need separate liability accounts per jurisdiction. One of our clients was transitioning from Avalara to Numeral for sales tax across channels — getting this right requires deliberate planning.

Reconciliation multiplied. Every marketplace generates its own settlement reports, business reports, and fee structures. If reconciling one Amazon marketplace takes 4 hours monthly, five marketplaces takes more than 20 — because you also need to consolidate into a unified view while handling currency conversions and intercompany eliminations if you’re running subsidiaries.

The solution structure: Maintain separate P&L visibility per marketplace. You need to know your contribution margin for Amazon US versus Amazon UK versus Amazon CA individually. A product profitable in the US at scale might lose money in the UK at lower volume because fixed advertising spend eats a larger share of smaller revenue.

Brands scaling internationally often need a fractional CFO experienced with marketplace finance to set up the reporting structure correctly from the start. Retrofitting multi-marketplace accounting is significantly harder than building it right the first time.

Amazon vs DTC — Separating Your Channel P&Ls with a Contribution Margin Waterfall

Every brand selling on both Amazon and Shopify needs separate channel P&Ls. This isn’t optional — it’s the only way to understand where you’re actually making money.

The challenge is structural. In most accounting systems, Amazon isn’t a separate “business unit.” You might have business units by brand or product line, but Amazon runs within each. You can’t add Amazon as its own entity without double-counting. The solution: add Amazon and Shopify tabs to your reporting — separate analytical views that slice the data by channel.

Worked Example: Channel Contribution Margin for a CPG Brand

Here’s a real contribution margin waterfall from one of our clients — a green cleaning products company selling on both Amazon and DTC. The numbers are representative of their actual channel economics:

Amazon channel (per $100 of revenue):

First-time customer revenue averaged about $20. With a 45% gross margin and Amazon fees layered on top, the first order was essentially breakeven or slightly negative after advertising. But the cohort data showed a three-month payback — by the third repeat order, acquisition cost was fully recouped. After that, each subsequent order contributed directly to profit.

Shopify/DTC channel (per $100 of revenue):

Same product, same gross margin. But the contribution margin after marketplace fees diverges: 20% on Amazon versus 34% on DTC. After advertising, Amazon lands at roughly 10% CM3 while DTC comes in at 19%.

The bottom line: this doesn’t mean Amazon is bad — it means you need to understand the economics before you scale spend on either channel. Amazon moves volume with lower effort per order. DTC keeps more margin per dollar but costs more to scale. The strategic question is how much cash you can absorb in first-order losses to grow your customer base — and that requires understanding your cash position, credit facilities, and runway.

The typical eCommerce company needs four to five dollars of revenue to cover every dollar of fixed costs. If your blended CM3 across channels is 15%, you need roughly $6.67 of revenue per dollar of fixed overhead. That math tells you exactly how much volume you need to sustain profitability.

Amazon Advertising Accounting — Expense It When You Spend It

There’s a temptation to match Amazon ad spend with the revenue it generates — capitalizing the cost as an asset and recognizing it over time. Don’t.

You must recognize advertising expense when you spend it. You can’t inventory ad spend and apply it when the revenue comes in. This is a GAAP requirement, not a preference.

What this means practically:

• Amazon PPC spend shows up as a marketing expense in the period incurred
• High-spend launch months look worse on the P&L even if they generate future returns
• Track ROAS and TACOS separately from your P&L to understand advertising efficiency

The benchmark: Amazon TACOS of roughly 25% is viable if your contribution margin structure supports it. But aggregate numbers mislead. A ROAS of 2x on Amazon may actually lose money on non-repeat purchasers once you account for all fees.

We build ROAS and net profit trackers for our Amazon clients so marketing teams can model scenarios weekly — “what happens if we increase spend by $10K? What’s our breakeven ROAS at current margins?” — without waiting for month-end close.

Different products require different bid strategies, even within the same line. A $12 product and an $18 product need different bids because the margin structures differ. The smart approach: bucket your spend into fixed “always-on” brand defense (protecting branded search terms) plus variable efficiency-rated spend that scales with performance. One of our clients runs $300K/month as baseline brand spend on Amazon alone — that’s a fixed marketing cost that needs to be planned and budgeted, not treated as discretionary.

Reimbursements — The Revenue You’re Probably Leaving on the Table

Amazon loses and damages inventory. It happens at scale. The question is whether you have a systematic process for recovering what’s owed to you. Systematic reimbursement recovery typically finds 1–3% of annual Amazon revenue in missed claims — on a $5M Amazon business, that’s $50K–$150K left on the table.

Common reimbursement categories:

• Lost or damaged inventory in FBA warehouses
• Inbound shipment discrepancies (fewer units received than sent)
• Customer returns not restocked (return processed but inventory credit never issued)
• Incorrect fee charges (dimensional weight errors, removal fee mistakes)
• Destroyed inventory without authorization

Important 2026 change: Amazon now calculates reimbursements based on product sourcing cost rather than selling price. Lower payouts per claim and higher denial risk without documentation. You need sourcing invoices, supplier price sheets, and landed cost details on file to support every claim.

Best practices:

• Audit inbound shipments and flag discrepancies within 72 hours
• Run monthly reconciliation of inventory adjustments
• Use automated tools (SellerQI, Refunzo) to scan for missed claims across 20+ checkpoints
• Batch similar claims and avoid peak periods like Q4
• Follow up within 14 days if no response
• Maintain comprehensive documentation for 85%+ approval rates

Treat reimbursements as a systematic process. Sellers who audit proactively recover significantly more than those filing ad-hoc claims.

When to DIY vs When to Hire Amazon Accounting Help

Not every Amazon seller needs a specialized accounting firm. Here’s how to think about the thresholds:

Under $500K Amazon revenue: You can likely handle this with A2X or Link My Books posting to QuickBooks (see our comparison of Xero vs QuickBooks for online sellers), plus a general bookkeeper who understands the chart of accounts structure described above. The volume is low enough that manual reconciliation is manageable.

$500K–$3M Amazon revenue: You need a bookkeeper who specifically understands Amazon FBA accounting — not a generalist. The settlement reconciliation, fee decomposition, and inventory tracking require someone who’s done it before. A tool like A2X is essential at this stage.

$3M–$10M Amazon revenue: The complexity justifies specialized help. Multi-SKU inventory management, advertising spend optimization, and channel P&L separation require more sophistication. This is where brands typically bring in a fractional CFO with eCommerce expertise to set up the reporting framework and oversee the bookkeeping process.

$10M+ or multi-marketplace: You need a dedicated Amazon accounting function — whether that’s an in-house team or a specialized firm. Multi-marketplace reconciliation, currency management, international tax compliance, and channel-level contribution margin analysis require senior finance expertise. This is where getting it wrong becomes truly expensive.

The key indicator isn’t just revenue — it’s complexity. A single-marketplace, 10-SKU seller at $5M is simpler than a five-marketplace, 500-SKU seller at $3M. If you’re unsure, ask yourself: “Can I tell you my contribution margin by channel, by marketplace, within 60 seconds?” If not, you probably need help.

Frequently Asked Questions

Where do Amazon FBA fees go on a P&L?

Keep Amazon FBA fees out of COGS. Place referral fees and fulfillment fees as variable expenses below gross margin in your contribution margin waterfall, so your gross margin stays comparable across Amazon, Shopify, and wholesale. Storage fees sit as operating expenses. Advertising must be expensed when incurred per GAAP. This gives you clean channel-level visibility and avoids confusion during due diligence or fundraising.

What is the biggest Amazon FBA accounting mistake?

Recording the biweekly settlement deposit as a single “sales” entry. This loses all visibility into fees, refunds, reimbursements, and adjustments — making your P&L fiction. Each settlement must be decomposed into gross sales, referral fees, fulfillment fees, storage fees, ad spend, refunds, and reimbursements, with each recorded in the appropriate account.

How do I reconcile Amazon settlement reports?

Pull the settlement report for each payout period from Seller Central, then post each component (revenue, fees, refunds, reimbursements) as separate journal entries to the correct accounts. Track the difference between what Amazon owes you and what’s in your bank as deposits-in-transit. Reconcile every settlement period. Tools like A2X or Link My Books automate this at scale.

Do I need separate books for Amazon and Shopify?

You don’t need separate books, but you need separate analytical views. Maintain one set of books with Amazon and Shopify tabs in your financial reporting showing channel-level P&Ls. Your gross margin should be similar across channels (same product cost), but contribution margins will diverge due to Amazon’s 25–40% fee structure versus Shopify’s 2.9% + $0.30 processing.

How do multi-marketplace Amazon sellers handle currency and tax?

Each marketplace pays in local currency (USD, CAD, GBP, EUR, AUD). Use local bank accounts or processors like Airwallex to minimize 2–4% FX fees. Set up separate tax liability accounts per jurisdiction — VAT for UK/EU, sales tax for US/CA. Automate with accounting integrations that handle multi-currency conversion and marketplace-specific posting. Consider subsidiary structures for major international markets.

Is Amazon FBA accounting the same as Amazon FBA bookkeeping?

They overlap, and most operators use the terms interchangeably, but they describe different levels of the same workflow. Amazon FBA bookkeeping is the transactional layer — weekly settlement decomposition, fee categorization, deposit-in-transit reconciliation, reimbursement tracking. Amazon FBA accounting is the financial-reporting layer that sits on top — month-end close, channel P&L production, accruals for unbilled fees, multi-marketplace consolidation. A clean bookkeeping process is the precondition for accurate accounting; bad bookkeeping at the source means every financial statement is fiction.

What does Amazon FBA bookkeeping cost in 2026?

At the $1M–$5M revenue band, expect $800–$1,800/month for FBA-competent bookkeeping (single marketplace, weekly reconciliation, A2X or Link My Books for settlement decomposition). At $5M–$25M with multiple marketplaces, expect $1,800–$4,500/month plus the A2X / Link My Books platform fee ($19–$199/month depending on order volume). Below $1M revenue you can DIY with the right setup, but plan on 3–5 hours per week minimum and a willingness to learn the settlement-report format.

Do I need separate Amazon FBA bookkeeping software, or is QuickBooks Online enough?

QuickBooks Online (or Xero) is your ledger; you don’t need a separate bookkeeping platform. You DO need a settlement-decomposition tool that posts to QBO/Xero on a schedule — A2X and Link My Books are the two reasonable choices. The native Amazon Seller Central QuickBooks connector is fine for the simplest single-marketplace cases and underbuilt for multi-marketplace, multi-currency, or high-volume FBA bookkeeping. See our QuickBooks for ecommerce guide for the broader setup.
