Selling on Amazon.sg alongside Shopify
Amazon.sg is another place for Singapore shoppers to find your products, alongside Shopee, Lazada and TikTok Shop. Selling there doesn't mean giving up your Shopify store: many brands keep Shopify as the main catalogue and stock record and list a selection on marketplaces. This guide covers registering as a Singapore seller, Fulfilment by Amazon (FBA), connecting Shopify, keeping inventory in sync, GST, and how Amazon.sg compares with other marketplaces.
This is general information, not tax or legal advice. It summarises Amazon, Shopify and IRAS sources as of the date above. We link to Amazon's fee pages rather than quoting fees, because they change.
Registering as an Amazon.sg seller
Amazon's registration page for Singapore asks Singapore-based sellers to have:
- A mobile number and email address.
- An identity document: Singapore passport, NRIC or driving licence.
- A bank or credit card statement.
- Your business registration number (UEN) and an ACRA document confirming the business registration.
- Proof of your link to the business, such as being the beneficial owner or legal representative.
Amazon reviews the documents and verifies the account holder's identity before you can sell. If you haven't registered a business yet, see our ACRA registration guide. Amazon's Sell on Amazon Singapore site also explains the Professional selling plan and selling to other Amazon stores.
Fulfilment by Amazon in Singapore
With FBA, you send stock to Amazon and it handles storage, picking, packing, delivery and customer service for those orders. Amazon's Singapore FAQ says FBA stock for Amazon.sg must go to the Singapore fulfilment centre; you can't serve Singapore customers from a US fulfilment centre, because FBA barcodes are specific to each marketplace. Products must meet Amazon's FBA inventory requirements for labelling and packaging.
The alternative is fulfilling Amazon orders yourself, using the same couriers you use for Shopify. Our shipping guide covers local options.
Fees
Amazon.sg charges include a selling plan subscription, referral fees by category, and, if you use FBA, fulfilment and storage fees. See Amazon's FBA fulfilment fees and storage fees pages, and the current referral fee schedule in Seller Central. Amazon has run subscription fee waivers for Amazon.sg; check the current terms on its site before you sign up.
Connecting Shopify to Amazon.sg
Shopify Marketplace Connect, formerly Codisto, is Shopify's own app for selling on Amazon, eBay, Walmart and Target Plus from your Shopify admin. Its listing says you can sell in all marketplace regions with built-in currency conversion, and its help centre says it supports listings on all Amazon sites. You need:
- An Amazon Professional seller account for the marketplace you're connecting; individual accounts can't connect, according to the setup guide.
- A verified seller account registered in the right country, as Shopify's requirements page notes.
Neither source names Amazon.sg specifically, so confirm it appears in the list when you click "Add new Amazon connection". Third-party connectors also exist, such as CedCommerce Amazon Channel; check its listing and support team for Amazon.sg before installing.
Keeping inventory in sync
Marketplace Connect's listing says it syncs listings, orders and inventory with Shopify, so a sale on Amazon reduces stock in Shopify and the order appears in your admin. In practice:
- Keep Shopify as the single source of stock levels.
- Keep a small buffer on marketplace listings for fast sellers to avoid overselling.
- For FBA stock, track it as a separate location, because it's sitting in Amazon's warehouse, not yours.
- Match SKUs exactly between Shopify and Amazon.
GST on marketplace sales
If you're GST-registered, sales you make through Amazon.sg to Singapore customers are your supplies, and you account for GST on them in the same way as Shopify sales. IRAS's e-commerce page covers how GST applies to online sales, and its guide on when to report supplies sets the timing. Amazon's fees are a business cost to you. Export Amazon's settlement reports each month and reconcile them with your accounts so marketplace sales, refunds and fees are all recorded.
Amazon.sg vs Shopee, Lazada and TikTok Shop
There's no single best marketplace. Things to weigh:
- Audience: Shopee and Lazada are long established in Singapore with frequent sales campaigns; Amazon.sg reaches shoppers who already buy from Amazon.
- Fulfilment: FBA can take logistics off your hands; Shopee and Lazada have their own fulfilment programmes.
- Pricing pressure: all marketplaces push price competition; protect your Shopify store's pricing and brand.
- Global reach: an Amazon account can be extended to other Amazon stores.
Our Shopee and Lazada guide and TikTok Shop guide cover those channels. Start with one marketplace, measure margin after fees, and expand only if it pays.
Marketplaces win one-off sales; your own store is where repeat customers live. See our guide to loyalty programmes and gift cards on Shopify.
Frequently asked questions
What do I need to register as an Amazon.sg seller?
Amazon's Singapore registration page lists a mobile number and email, an identity document such as an NRIC or passport, a bank or credit card statement, your UEN, an ACRA business verification document and proof of your link to the business. Amazon then verifies your identity before you can sell.
Can I connect my Shopify store to Amazon.sg?
Shopify Marketplace Connect, Shopify's own marketplace app, says it supports listings on all Amazon sites and needs an Amazon Professional seller account for the marketplace you choose. Confirm Amazon.sg appears when you add the connection before planning around it.
How does FBA work for Amazon.sg?
With Fulfilment by Amazon you send stock to Amazon's Singapore fulfilment centre, and Amazon picks, packs and delivers Amazon.sg orders. Amazon says you can't serve Singapore customers from a US fulfilment centre. FBA fees are separate from referral fees; check Amazon's current fee pages.
Do I charge GST on Amazon.sg sales?
If you're GST-registered, your Amazon.sg sales to Singapore customers are your supplies and you account for GST on them as usual. Amazon's own fees are a separate cost to you. Check how Amazon's reports show GST and reconcile them with your GST return.
Is Amazon.sg better than Shopee or Lazada?
It depends on your products, margins and customers. Compare fees, fulfilment options and how shoppers in your category buy on each; Amazon.sg can suit brands that want to use FBA or reach existing Amazon shoppers. Many sellers test one marketplace first while keeping Shopify as their main store.
Want your own store as the hub for every marketplace? A Shopify trial lets you set up your catalogue and test Marketplace Connect before you list on Amazon.sg.
