Platform fee reconciliation: what Shopify, Amazon and PayPal are really charging you

Ask most Australian ecommerce sellers how much they pay in platform fees each month, and they can’t tell you within a thousand dollars. Not because they don’t care. Because the fees are buried across settlement reports, transaction records, monthly invoices and multiple platforms, and nobody has stitched the full picture together.

That’s a real problem. Platform fees are the quiet killer of ecommerce margins. A store that looks profitable at the sales line can be operating on much thinner margins than the owner thinks, once every fee category is actually accounted for.

This guide covers ecommerce platform fee reconciliation for Australian sellers. What Shopify, Amazon, PayPal, Stripe and others are actually charging you, how those fees show up in your accounting, where sellers most often get caught out, and how to reconcile the whole picture cleanly so you know your real gross margin.

Why the fees are so easy to miss

Every ecommerce platform structures its fees differently, and most of them deduct fees from your payout before the money hits your bank account. The deposit landing in your Xero bank feed is already net of fees. Code it as sales and the fees are invisible.

Take a common scenario. A seller gets a Shopify payout of $8,500 and codes it to a Sales account. Their P&L shows $8,500 in revenue. The actual gross sales were $9,200 with $700 in various fees deducted along the way. That $700 has disappeared from the books completely. Revenue is understated, expenses are missing, and the tax return doesn’t reflect what actually happened.

Multiply that across a full year and multiple platforms, and the gap between “the numbers in your accounting file” and “what the business actually did” gets significant fast.

What each platform actually charges Australian sellers

The exact rates change from time to time and depend on your plan, region, and product category. What matters more is knowing what fee categories to look for on each platform.

Shopify charges a monthly subscription fee based on your plan tier (Basic, Shopify, Advanced, or Plus), a Shopify Payments transaction fee that sits around 1.7% plus 30 cents for domestic Australian cards and higher for international ones, and an additional fee if you use a third-party payment gateway instead of Shopify Payments. On top of that, you’ll see charges for third-party apps, shipping labels bought through Shopify, and GST on Shopify’s own fees to Australian merchants — that GST is claimable as an input tax credit if you’re registered.

Amazon (both AU and international marketplaces) hits sellers with more categories. Referral fees run 6% to 15% depending on category. FBA fulfilment fees per unit if you use Fulfilment by Amazon. FBA storage fees monthly, plus long-term storage charges on inventory held over 365 days that only appear twice a year. Sponsored Products advertising, refund administration fees, international selling fees on cross-border orders, and currency conversion fees on foreign settlements.

PayPal charges around 2.6% plus 30 cents for domestic sales and a higher rate for cross-border transactions. Add a currency conversion fee that’s embedded in the exchange rate (easy to miss), and a chargeback fee whenever a dispute gets raised.

Stripe is roughly comparable 1.7% plus 30 cents for Australian cards, higher for international, a 2% currency conversion fee, chargeback fees, and an instant payout fee if you enable early settlement.

Afterpay and Zip charge merchants more than most other gateways. Afterpay typically sits around 4% to 6% of the sale plus a fixed fee. Zip is in a similar range depending on merchant tier. Worth tracking as its own line because the rate is high enough to affect gross margin decisions.

eBay charges a final value fee of 9.9% to 14.9% depending on category, insertion fees on listings above your monthly allowance, Promoted Listings fees at whatever rate you set, and international selling fees.

Etsy charges a listing fee of USD $0.20 per item listed, a 6.5% transaction fee on the total sale price, a payment processing fee of 3% plus $0.25 AUD, and Offsite Ads at either 12% or 15% depending on your annual sales volume.

For most Australian ecommerce sellers, the combined effective fee rate across all platforms lands somewhere between 5% and 15% of gross sales. If you don’t know where your business sits in that range, you don’t really know your gross margin either.

The fees Australian sellers most often miss

Some fees are easier to overlook than others because they don’t appear as separate line items on a monthly invoice. They’re baked into net settlements or applied as adjustments across multiple transactions.

Currency conversion fees are the big one. Sellers receiving USD or GBP payouts through Shopify Payments, PayPal, or Payoneer are paying a conversion margin on top of the actual exchange rate. It rarely shows as a separate line it’s built into the AUD amount that lands in the bank.

Amazon FBA storage fees don’t sit on their own line either. They come through as adjustments within settlement reports. Long-term storage fees are particularly sneaky because they only hit twice a year, then show up as a large unexplained deduction that catches sellers off guard.

Refund reversal fees on returns are another one. When a customer refunds a purchase, some platforms don’t reverse the transaction fee they originally charged you. You’re effectively paying to process the sale and paying again to process the refund.

Chargeback and dispute fees sit around $15 to $25 per chargeback on Stripe and PayPal. Any store dealing with regular disputes needs to track these — for higher-volume merchants they add up to real numbers over a year.

Offsite Ads on Etsy is 12% or 15% of the sale price when Etsy runs ads for your listings and a buyer purchases within 30 days. Most Etsy sellers don’t realise this is a separate charge from the standard transaction fee.

International selling fees on Amazon and eBay are typically a small percentage added on cross-border sales. Easy to lump into general fees and miss the actual amount.

Rounding differences are usually small but worth tracking. Platform payouts can round in unexpected ways and create tiny reconciliation gaps that add up across thousands of transactions.

GST on platform fees for Australian sellers

Most of the fees listed above include GST if the platform is registered for Australian GST. That GST is claimable as an input tax credit on your BAS. But only if you’re GST-registered yourself and only if the fees are correctly recorded in Xero with the right tax code applied to each line.

Shopify, Stripe (via Stripe Payments Australia) and PayPal all charge GST on fees to Australian merchants. Amazon charges GST on its fees to Australian sellers under the electronic distribution platform rules in Australian tax law.

Sellers who code net payouts to sales without capturing fee detail are missing these input tax credits every quarter. Across a year on any real sales volume, the missed credits easily reach four or five figures.

Getting GST right on platform fees comes down to three things happening together. The fee amount needs to be recorded in Xero as an expense. The correct GST on Expenses tax rate needs to be applied so the input tax credit flows through to your BAS. And the gross sale (not the net payout) needs to be what’s recorded as revenue.

Miss any of those three and your BAS is wrong and you’re overpaying tax to the ATO.

How to actually reconcile platform fees

There are three ways to do this, and each has its place depending on your volume and complexity.

The first is manual reconciliation. Download the settlement report from each platform every payout cycle, cross-check against the bank deposit, and code fees to the right expense accounts by hand. It’s free but slow. Works for very low-volume sellers doing under 50 orders a month across one or two platforms.

The second is spreadsheet-assisted reconciliation. Build a Google Sheet or Excel workbook that lets you paste in payout reports and calculates the fee breakdown for you. Faster than pure manual, but still requires ongoing input. Suits medium-volume single-platform sellers who don’t want to pay for software yet.

The third is automated reconciliation using A2X or Link My Books. The software connects to your ecommerce platform, pulls each payout automatically, and posts a summarised journal entry to Xero with sales, every fee category and refunds mapped to their own accounts. Bank reconciliation matches to the cent. This is the standard setup for any store doing real volume, and it’s what most A2X-certified ecommerce accountants will recommend.

Whichever method you use, the outcome should be the same. Every payout broken down into gross sales, fees by type, refunds and adjustments. The bank deposit ties back to the underlying transactions. Fee expenses visible in your P&L as distinct line items you can actually analyse.

Common platform fee reconciliation mistakes

Coding the payout as revenue and never capturing the fee detail is easily the most common issue. It hides real costs and understates revenue simultaneously.

Lumping every fee into a single “Merchant Fees” account is the second. This masks which platform is costing you what. When you can’t see Shopify fees vs Stripe vs PayPal as separate lines, you can’t make informed decisions about which platforms are actually working for the business.

Treating Offsite Ads or Promoted Listings as a normal platform fee is another common one. These are advertising costs. Code them separately so you can actually evaluate whether the ad spend is producing a return.

Missing GST on platform fees is quietly expensive. Australian sellers can claim input tax credits on Shopify, Stripe, Amazon and PayPal fees. Coding them as GST-Free misses those credits every quarter.

Not accounting for currency conversion is a big one for sellers moving into US or UK marketplaces. If you sell in USD and receive USD before converting to AUD, the conversion margin is a fee that needs to be tracked separately from the sale amount.

Ignoring small fees like chargebacks and rounding sits in the background. Individually small. Collectively significant across a full year of transactions.

Not reconciling per settlement period is what creates timing issues. Amazon and Etsy have their own settlement cycles. Trying to reconcile at month-end rather than per settlement mixes multiple periods together and hides errors in the noise.

When platform fee reconciliation needs a specialist

For a low-volume store on a single platform, doing fee reconciliation yourself is manageable. Once you’re running multiple platforms, multiple currencies, or serious transaction volume, the workflow becomes worth handing to someone who does it every day.

Signs it’s time to get specialist help:

• You sell across multiple platforms (Shopify + Amazon + eBay etc)
• You receive foreign currency payouts from Amazon US, Shopify Payments international, or PayPal cross-border
• Your gross margin figure feels wrong or has drifted significantly from where it should be
• Your BAS keeps showing GST discrepancies you can’t explain
• Manual reconciliation is taking hours per week and you’re still not confident it’s accurate.

Frequently asked questions

What is platform fee reconciliation? It’s the process of accounting for every fee an ecommerce platform charges you and matching those fees back to your gross sales and bank deposits. Done properly, your revenue, expenses, GST and gross margin figures in Xero reflect what actually happened. Done incorrectly, your books show just the net payout as sales and everything else disappears.

How much do Shopify, Amazon and PayPal charge Australian sellers in total fees? Combined effective fee rates typically land between 5% and 15% of gross sales. It depends which platforms you use, your subscription tier, your product category, and how many international transactions you process. Sellers running multiple platforms plus advertising products like Offsite Ads or Sponsored Products usually sit at the higher end.

Are platform fees tax-deductible in Australia? Yes. Fees charged by Shopify, Amazon, PayPal, Stripe, Afterpay, eBay, Etsy and other ecommerce platforms are deductible business expenses. If you’re GST-registered and the platform charges GST on its fees to Australian merchants, that GST portion is also claimable as an input tax credit on your BAS.

Do I need software to reconcile platform fees? Not for low-volume single-platform stores. Once you’re processing meaningful volume or selling across multiple platforms, automated tools like A2X or Link My Books save significant time and produce more accurate books than manual reconciliation. For most Australian ecommerce businesses doing real volume, automated is the standard.

How do I claim GST credits on Shopify fees? The fee amount needs to be recorded in Xero as an expense with the GST on Expenses tax rate applied. That flows the input tax credit through to your BAS automatically. A2X handles this during the mapping setup. If you’re reconciling manually, you have to apply the tax code to each fee transaction yourself.

What’s the difference between platform fees and payment processing fees? Platform fees are what the ecommerce platform (Shopify, Amazon, eBay) charges for using their marketplace or hosting your store. Payment processing fees are what the payment gateway (Stripe, PayPal, Shopify Payments) charges for handling the actual transaction. Some platforms combine both (Amazon, Etsy). Others separate them out (Shopify + Stripe as separate providers). Both are deductible.

Get your platform fee reconciliation done properly

If you don’t know your combined platform fee rate as a percentage of gross sales, you don’t know your real gross margin. And if your bookkeeping is coding net payouts as revenue, the situation is worse than that. Your revenue, expenses, GST and tax return are all missing information they should have.
