Amazon Integration
Amazon tracks what you sold. Stocksmith tracks what it cost you to make it. Orders sync in automatically, materials come off stock through your bills of materials, and every order carries a real cost figure — so you know your margin after Amazon's fees, not just your revenue before them.

Connect your Amazon seller account once through Amazon's Selling Partner API. From that point, orders flow into Stocksmith automatically — no CSV exports, no manual entry, no end-of-month reconstruction.
Stocksmith pulls your Amazon orders in hourly, on its own. Both North American and European marketplaces are supported, so a seller running Amazon.com and Amazon.co.uk can connect each one.
Finished goods stock decrements. If you manufacture the product, Stocksmith also updates the raw materials and components it consumed — right down through your bill of materials.
Every imported order is costed from your actual material prices, not a flat estimate. That gives you a true cost of goods per Amazon sale — the number you need before Amazon's fees are subtracted from it.
For product businesses that make things
Every Amazon seller knows the referral fee, the FBA fee, the storage charge. Those get subtracted in front of you, on the settlement report. What most manufacturers can't put a number on is the other side of the equation — what the unit actually cost to produce, using the material prices they paid on their last supplier order rather than the ones from six months ago.
That gap is where margins quietly disappear. You can be certain about Amazon's cut and still have no idea whether the product clears its costs, because the production figure is a guess. And a guess is exactly the kind of number that gets baked into your pricing and then becomes load-bearing.
Stocksmith is built around bills of materials, so the production side stops being a guess. When an Amazon order imports, it doesn't just decrement a SKU count — it traces back through every component and raw material in the product's recipe and costs the order from what you actually paid. One customer tracks 600 fragrance oils across hundreds of SKUs. Another manages products with 200 parts each. General inventory tools aren't built for that.
Build recipes with as many levels as your products need — raw materials, sub-assemblies, finished goods. Stock updates cascade automatically when Amazon orders import.
Every order that imports from Amazon carries an accurate cost, calculated from your actual material costs. Set that against the fee side and you have a real margin, not a revenue figure.
Set reorder thresholds that reflect your production cycles, not just shelf counts. Get alerted before a material stockout stops a run — and before an Amazon listing goes out of stock.
Managing Amazon inventory manually
With Stocksmith + Amazon
Amazon and beyond
Very few product businesses sell in one place. Amazon is usually the scale channel, but there's a Shopify store for DTC, Faire for wholesale, maybe Etsy or a WooCommerce site as well. Every one of them draws down the same physical stock.
Stocksmith connects all of them to a single inventory. An Amazon order doesn't know your Shopify store has already committed the units — but Stocksmith does. Both adjust the same materials pool, so you don't over-commit stock you can't actually produce. There's more on how this works across channels in our guide to multi-channel inventory management.
One thing worth being straight about: Stocksmith imports your Amazon orders, but it doesn't write stock quantities back to Amazon listings. Automatic stock push-back is available for Shopify, WooCommerce, Etsy, Faire and Square. For Amazon, Stocksmith is the accurate record behind the channel rather than the system updating your listing counts.

Connecting an Amazon seller account is available on the Business plan and above — $166/month billed annually, or $199/month billed monthly. Stocksmith's smaller plans start at $20/month but don't include Amazon, so if Amazon is one of your channels, Business is where to start.
See the full plan comparison →Seller Central tracks the finished units you list and sell. It has no view of what went into making them. Stocksmith tracks the manufacturing side: raw materials, components, sub-assemblies, and the recipe that turns them into a sellable product. When an Amazon order imports, Stocksmith decrements every material it consumed and attaches a real cost to the order — so you can see the margin, not just the sale.
No — Amazon is order-import only. Stocksmith brings your Amazon orders in and keeps your material and finished-goods inventory accurate, but it does not write quantities back to Amazon listings. Automatic stock push-back is available for Shopify, WooCommerce, Etsy, Faire and Square. If pushing stock levels to Amazon is essential to your workflow, it's worth knowing that before you start a trial.
Yes, and it's one of the main reasons product businesses use it. Connect Amazon alongside Shopify, Faire, Etsy, WooCommerce and Square. All orders pull from the same inventory pool, so a wholesale run on Faire and a spike on Amazon are both drawing down the same materials — and you can see it happening rather than finding out when a listing runs dry.
It's an authorisation through Amazon's Selling Partner API — you approve Stocksmith's access from your Amazon seller account and the two are linked. North American and European marketplaces are handled separately, so if you sell in both regions you connect each one. No developer needed and no API keys to manage yourself.
Stocksmith holds a bill of materials for each product — every material, its quantity, and what you actually paid for it. When an Amazon order imports, it's costed from those figures using a weighted-average material cost, so the number reflects your real purchase history rather than a fixed estimate. That feeds straight into your COGS reporting at the end of the period, with no manual reconstruction from settlement reports.
Stocksmith is built for small-batch product businesses and small manufacturers, not factories — no per-seat pricing and no sales call to get started. The Amazon connection is available on the Business plan and above, which is $166/month billed annually ($199/month billed monthly). Smaller plans start at $20/month but don't include Amazon, so if Amazon is your channel, Business is the entry point.
Materials, components and finished goods tracked in one place.
Real cost of goods per order, calculated from your bills of materials.
Orders from every channel in one queue, costed as they arrive.
