How It Works

From Amazon sale to shipped package in four steps.

1

Connect Seller Central

Sign up free and authorize atoship through Amazon's official SP-API. Takes about 30 seconds. Your credentials stay with Amazon.

2

FBM Orders Flow In

Pending and unshipped FBM orders import automatically. No copy-pasting addresses, no CSV uploads.

3

Compare Rates & Print

Every order shows rates from all carriers. Pick the best one or let atoship auto-select the cheapest. Print one label or a hundred.

4

Amazon Gets the Tracking

As soon as a label is created, the tracking number and carrier info sync back to Seller Central. Your buyer sees the update instantly.

Built for Amazon Sellers

Everything you need to ship FBM orders faster and cheaper.

Auto-Import FBM Orders

Bulk Label Printing

Select a batch of orders, choose a carrier, and print all your labels at once. Handle high-volume days without breaking a sweat.

Tracking Auto-Sync

Tracking numbers push back to Amazon automatically. Your buyers get notified and your account health stays green.

Frequently Asked Questions

Common questions from Amazon sellers.

Does it work with FBA orders?
FBA orders are fulfilled by Amazon, so those ship from Amazon's warehouses. However, atoship helps with FBA inbound shipments, so you can compare rates when sending inventory to Amazon fulfillment centers. For seller-fulfilled (FBM) orders, atoship handles the full workflow.
Will it affect my Amazon account health or metrics?
No. Tracking numbers sync back to Amazon faster than doing it manually, which actually helps your on-time delivery rate. Atoship uses Amazon's official SP-API, so everything is fully compliant with Amazon's terms of service.
How do orders sync from Amazon?
Atoship connects through Amazon's Selling Partner API (SP-API). New FBM orders appear within minutes of being placed. We run syncs throughout the day so nothing gets missed, even during peak sales periods.
Can I still use Amazon Buy Shipping?
Yes. Connecting atoship doesn't change anything in Seller Central. You can compare rates in atoship and still buy through Amazon if their rate happens to be better. Most sellers find atoship rates are consistently lower.
Does it handle Amazon Prime or Seller Fulfilled Prime?
For Seller Fulfilled Prime (SFP), you need to meet Amazon's delivery speed requirements. Atoship shows delivery estimates for each carrier so you can pick a service that meets the Prime delivery window while still saving on cost.
Can I manage multiple Amazon marketplaces?
Yes. You can connect multiple Amazon seller accounts or marketplaces (US, Canada, Mexico, etc.) under one atoship account. All orders appear in a unified dashboard with marketplace filters.
