Every Amazon sale adjusts Shopify first.
Shopify is the single source of truth. An FBM sale on Amazon updates Shopify before anything else, then every other channel follows, so one number stays true everywhere.

Connected in three steps.
A wizard does the setup, and history does the heavy lifting: forecasting starts with real Amazon data on day one.
-
1
Connect Amazon
The connect wizard links Amazon alongside Shopify, and FBA or FBM is detected automatically for every SKU.
-
2
Match your catalog
SKUs match automatically. Mismatches get manual mapping, so you decide exactly which listings pair up.

Backfill 24 months
24 months of order history import on day one, and Amazon demand feeds the same cross-channel forecast as every other channel.
Mirrored, never split.
Amazon sees your full available stock minus buffer, exactly like every other channel. An optional per-channel max cap limits what Amazon may show, without touching the others.
Pause Amazon any time: pausing pushes zero stock, so nothing sells while the channel is paused.
Optional max cap can lower this further. Paused pushes 0.
One source of truth. Every channel.
