Amazon

Connect your Amazon seller account to bring your orders, fees, refunds, payouts, and listings with their stock into Nummbas. Nummbas reads your Amazon data. The one change it can make on Amazon is the quantity of a listing you ship yourself, and only after you turn on stock levels sent to Amazon in Product Command Center.

Before You Start

You need an Amazon Professional selling account. Sign in to Seller Central as the account owner to approve Nummbas.

Connection Method

OAuth: you sign in to Seller Central and agree to give Nummbas access. You do not need an API key.

How to Connect

Go to Dashboard > Integrations
Select Connect Store on the Amazon card
Choose the country of your main Amazon store
Sign in to Seller Central as the account owner, review the access Nummbas asks for, then agree
Amazon sends you back to Nummbas, and your Amazon data starts to sync

You can also start in Seller Central: find Nummbas in the Selling Partner Appstore and select Authorize Now. If you already use Nummbas, sign in and confirm on Amazon. If you are new to Nummbas, create your account and choose Amazon as your main sales source. Once your plan is set up, Nummbas asks for your main Amazon store and takes you to Seller Central to approve the connection.

Each Amazon connection covers one Amazon region: North America, Europe, or Far East. Nummbas reads orders and money from every Amazon store you sell in within that region, and listings and stock from your main store. To add another region, add another Amazon connection. Your plan sets how many connections to one platform you can have.

When you first connect, Nummbas reads up to two years of past Amazon orders, which is as far back as Amazon allows. Amazon limits how fast orders can be read, so a large history can take several hours to finish.

What Nummbas Does Not Do

Nummbas does not edit your listings or prices, message buyers, ship orders, or issue refunds. It changes a listing's quantity only on listings you ship yourself, and only when you have turned on stock levels sent to Amazon. It never changes listings Amazon fulfills.
Nummbas never reads or stores buyer names, email addresses, phone numbers, or street addresses from Amazon.

Product Costs

Amazon does not share what your products cost you. If a product in your store has the same SKU, Nummbas uses that product's cost. Otherwise, enter the cost of each Amazon product in Nummbas, and your profit includes your product costs.

Stock and Inventory

Your Amazon listings and their stock appear in Product Command Center. With Inventory, Nummbas matches each listing to the product with the same SKU, takes each Amazon sale out of stock once, and shows the stock Amazon holds for you as the Amazon FBA location. If you turn on stock levels sent to Amazon in Inventory > Marketplaces, then for linked listings you ship yourself, Nummbas sends the available stock at your selected locations, minus the units you keep back. See the Inventory guide.

How Amazon Sales Are Counted

Nummbas adds your Amazon sales to the sales from your store or Stripe. Amazon collects the buyer's payment itself, so an Amazon sale does not also appear in Stripe.

If your Shopify, BigCommerce, Wix, or WooCommerce store also receives copies of your Amazon orders through a channel app, Nummbas matches each copy to its Amazon order by the Amazon order number and counts the sale once. A copy without the Amazon order number cannot be matched, and the Amazon card shows how many of these copies there are.

Nummbas Books

If you use Nummbas Books, your Amazon sales, fees, refunds, and payouts post to your books. Tax Amazon collects and pays itself is kept apart from the sales tax you owe. Adjustments wait in review until you record them.

Features Powered by Amazon Data

Dashboard KPIs: revenue, order count, and average order value include your Amazon sales
Product Command Center: Amazon listings with stock and sales pace, and margins once you add product costs
Customer Geography: where your Amazon orders ship, by country and region
Expense Intelligence: without QuickBooks or Xero, Amazon's fees appear under "Marketplace Fees", and fulfillment fees such as FBA fees under "Fulfillment and Shipping". With QuickBooks or Xero, they appear under the accounts your books use.

Approve Nummbas Again Each Year

Amazon asks sellers to approve their apps again every year. When it asks, go to Apps and Services > Manage Your Apps in Seller Central and choose Re-Authorize next to Nummbas. Amazon opens Nummbas. Sign in as an owner or admin if asked, then confirm on Amazon, and your connection is renewed.

Manage or Repair a Connection

If the connection shows Needs attention, select Reconnect and follow the approval steps. On plans that support several accounts, select Manage to view connections and add or disconnect an account. See Managing connections for details.

Disconnect Amazon

Select Disconnect on the Amazon card. Nummbas stops reading your Amazon account and deletes the Amazon orders, money movements, payouts, and listings it saved. If you use Nummbas Books, the entries already posted to your books stay there, because they are part of your accounting records. Your stock records stay in Inventory, and Amazon FBA stays as a location Nummbas keeps, which you can count or empty.

Amazon keeps Nummbas's access until you remove it there. In Seller Central, go to Apps and Services > Manage Your Apps and turn off authorization for Nummbas.

If you remove Nummbas in Seller Central first, the Amazon card asks you to reconnect. If you do not reconnect within 25 days, Nummbas deletes the Amazon orders, money movements, payouts, and listings it saved.
