Key takeaways
- Amazon bundles payment processing into its referral fee, but fulfillment, storage, and ad costs often add more per order than the referral fee does.
- On your own site, card processing is usually a small line item. The main cost is customer acquisition, which falls sharply on repeat orders.
- Amazon controls buyer contact and disbursement timing. A merchant account deposits to your bank and lets you build a customer list you own.
- Many sellers use Amazon for discovery and their own store for margin. That works best when you follow Amazon's communication rules and track per-channel costs.
If you're weighing selling on Amazon vs. your own website, the headline fees don't tell you much. Amazon's referral fee looks steep next to a card processing rate, but your own store has costs Amazon absorbs for you, such as traffic, fraud, and fulfillment. This guide breaks down what each channel actually costs per order. It walks through an illustrative $50 sale and covers payout timing and customer data. It ends with a framework for deciding where to put your effort.
Amazon updates its fee schedules regularly, and they vary by category, size tier, and season. Ecommerce platforms and payment processors change pricing too. Use the structure below to run your own numbers, and confirm current rates in Seller Central and with your providers.
What You Pay per Sale on Amazon: Referral, Fulfillment, and Ad Fees
Amazon fees stack. Most sellers pay several of the following on every order.
The Amazon Referral Fee
The Amazon referral fee is a percentage of the total sales price, and the rate depends on your product category. Some categories also have a per-item minimum. You don't pay a separate card processing fee on Amazon, because payment acceptance is part of what the marketplace provides. That matters when you compare it with a processing rate on your own site.
Selling Plan Fees
Amazon offers an individual plan, which charges per item sold, and a professional plan, which charges a monthly subscription. High-volume sellers usually pick the professional plan. Spread across your monthly orders, it becomes a per-order cost like any other.
Fulfillment by Amazon (FBA) Fees
If you use FBA, expect:
- Fulfillment fees per unit, based on size and weight tiers
- Monthly storage fees, which are typically higher during the holiday season
- Aged inventory surcharges on stock that sits too long
- Inbound and returns-related fees, depending on the program and category
Sellers who fulfill orders themselves avoid FBA fees. They take on shipping costs and Amazon's performance standards for delivery speed and tracking instead.
Advertising
Sponsored product ads are optional on paper. In practice, many categories are crowded enough that organic ranking alone won't move inventory. Divide your total ad spend by total orders to get an ad cost per order, and include it in every comparison.
What You Pay per Sale on Your Own Site: Platform, Processing, and Traffic
Your own store replaces the referral fee with several smaller line items and one large one.
Platform and Apps
- Shopify: a monthly plan fee plus paid apps for reviews, subscriptions, upsells, and shipping.
- WooCommerce: the core plugin is free, but you pay for hosting, premium extensions, security, and developer time.
Divide monthly platform costs by order volume. At low volume, this number can be surprisingly high.
Payment Processing
You pay card processing on every order. That cost covers interchange, network fees, and your processor's markup, or a single flat rate if you use a bundled processor. Online transactions are card-not-present, which generally carries higher interchange and more fraud exposure than in-person sales. Our guide to card-present vs. card-not-present fees and fraud rules explains why.
Shopify merchants also need to know that Shopify charges an additional transaction fee when you use a third-party gateway instead of Shopify Payments, unless an exception applies. Whether that trade-off pays off depends on your volume and rates. We run the numbers in Shopify Payments vs. a third-party gateway: the real cost math.
Traffic, Fraud, and Fulfillment
This is where your own site gets expensive:
- Customer acquisition: Google, Meta, influencer, and affiliate spend to bring in first-time buyers
- Chargebacks and fraud: you absorb disputes, fraud losses, and the tools to prevent them
- Shipping and returns: your own labels, packaging, and return processing, or a third-party logistics provider's fees
Selling on Amazon vs. Your Own Website: A Side-by-Side $50 Order
All figures in this section are illustrative assumptions, not quoted rates from Amazon, Shopify, or any processor. Replace them with your own category rates, size tier, ad data, and processing statement.
Assume a $50 item with free shipping to the buyer on both channels. Product cost is the same everywhere, so we leave it out and compare only channel costs.
| Cost Line (Illustrative) | Amazon (FBA) | Own Site: New Customer | Own Site: Repeat Customer |
|---|---|---|---|
| Referral fee (assumed 15%) | $7.50 | n/a | n/a |
| Card processing (assumed 3% + $0.30) | Included | $1.80 | $1.80 |
| Platform and apps, per order | Included in plan | $1.00 | $1.00 |
| Fulfillment and storage | $5.50 | $7.00 | $7.00 |
| Ad or acquisition cost per order | $5.00 | $12.00 | $1.00 |
| Fraud and chargeback allowance | Minimal | $0.50 | $0.50 |
| Returns allowance | $1.00 | $1.00 | $1.00 |
| Total channel cost | $19.00 | $23.30 | $12.30 |
Amazon Seller Fees vs. Shopify: Where the Gap Comes From
A few things stand out from the illustrative table:
- Processing is rarely the deciding factor. Card fees on your own site are a fraction of the referral fee. They are still worth optimizing, but they aren't what makes or breaks the channel.
- Acquisition cost decides it. A first-time buyer from paid ads can cost more on your site than on Amazon, because Amazon delivers shoppers who are already searching to buy.
- Repeat orders flip the math. When a past customer returns through email or a direct visit, your own-site cost drops sharply. On Amazon, that same customer may come back through search and click a competitor's ad, and you may pay for ads to win them again.
Using the same illustrative numbers, if 40% of your own-site orders came from repeat customers, your blended cost per order would be about $18.90. That is roughly even with Amazon. Your actual repeat rate is the single most important number to find in your own data.
Payouts and Cash Flow: Marketplace Disbursements vs. Your Merchant Account
Fees aren't the only cost. Timing matters too.
Amazon disbursements follow Amazon's schedule. Your balance sits in your seller account until it's released, and Amazon can hold part of it based on delivery dates, account health, or risk signals. If your payout looks smaller than expected, read why an Amazon account level reserve can shrink your disbursement.
A merchant account settles card batches to your business bank account, usually within a few business days, depending on your processor, batch cutoff, and bank. For details, see how long credit card deposits take with batches, weekends, and holidays. Processors can also apply reserves, especially for new accounts, sudden volume spikes, or preorders. The difference is that you have a direct relationship with your provider and can discuss terms during underwriting.
Practical steps for either channel:
- Forecast cash on the actual payout schedule, not on order dates.
- Track reserves and holds as a separate line in your books.
- Reconcile each channel's deposits against its sales report every month.
Customer Data, Repeat Sales, and Brand Control
This is the cost that doesn't appear on any fee statement.
| Factor | Amazon | Your Own Website |
|---|---|---|
| Buyer contact info | Limited and governed by Amazon's messaging rules | Yours, with proper consent |
| Email and SMS marketing | Restricted | Fully available |
| Product page design | Amazon's template | Your design |
| Pricing and promotions | Subject to marketplace policies | Your call |
| Competing ads on your listing | Common | None |
| Checkout experience | Amazon's | You optimize it |
Amazon's policies restrict marketing messages and inserts that direct buyers away from Amazon. Don't put "visit our website" cards in FBA packages or send off-platform promotions to Amazon buyers without reviewing Amazon's current buyer communication guidelines. Violations can put your seller account at risk.
On your own site, conversion is your responsibility. A clunky checkout wastes the ad money you spent to get the visitor there. Start with these payment fixes for checkout abandonment, and offer the wallets and payment methods your customers expect.
Multichannel Ecommerce: Using a Marketplace to Feed Your Own Store
Most growing brands don't pick one channel. They run multichannel ecommerce and give each channel a job.
What Works Within the Rules
- Build brand search demand. Strong Amazon reviews and packaging lead some shoppers to search your brand name, and they may find your site on their own.
- Differentiate your direct offer. Sell bundles, larger sizes, subscriptions, or exclusive products on your own site instead of the same SKU at a lower price. Review Amazon's pricing policies before planning price differences between channels.
- Invest in owned channels. Social content, email signups from your site, and wholesale relationships build an audience Amazon doesn't control.
Operational Must-Haves
- Inventory sync across channels to prevent overselling
- Separate profit and loss tracking per channel, including ads and fulfillment
- A merchant account and gateway that connect to your store platform, whether you sell through a Shopify payment integration or a WooCommerce payment integration
Should I Sell on Amazon or My Own Website? How to Decide
Use your own numbers, and work through these steps:
- Calculate Amazon's all-in cost per order. Include referral, plan, FBA, storage, ads, and returns. Pull the figures from Seller Central reports, not estimates.
- Calculate your own-site cost per order. Split it into new and repeat customers, and include processing, platform, fulfillment, acquisition, and chargebacks.
- Find your repeat rate. If customers rarely reorder, as with one-time purchases or bulky goods, Amazon's built-in traffic carries more weight.
- Check your cash flow tolerance. Can you handle marketplace reserves, or do you need faster, more predictable deposits?
- Weigh brand strategy. If customer relationships and pricing control are central to your business, your own store deserves investment even before it's the cheaper channel.
Amazon often makes sense first if you have a commodity-style product, limited marketing budget, or need fast validation.
Your own site often deserves priority if you sell consumables, subscriptions, or a distinctive brand where repeat purchases and email marketing drive profit.
Next Steps
The real question in selling on Amazon vs. your own website is where your customer acquisition and repeat sales economics point. Run the per-order math for each channel, then revisit it every quarter as your fees, ad costs, and repeat rate change.
