For Amazon sellers
Stop chasing ACOS and stockout alerts after the Buy Box is gone.
Tideline watches your Sponsored Products and Brands bids, drafts FBA reorder POs from real velocity, and parks Amazon buyer-message replies in your voice — overnight, before the 24-hour SLA clock runs out.
Where sellers leak money
Three places the Buy Box slips while you sleep.
Each row points at the surface Tideline watches — pick the one bleeding the most today.
- ACOS drift on Sponsored Products and Brands.Bids creep while you sleep, TACoS edges higher, and the weekly review shows a week of wasted spend you can't undo.
- FBA stockout windows kill the Buy Box.Days of out-of-stock cost you organic rank and the offer badge. The reorder window is missed by days because no one caught the velocity dip.
- Late buyer-message replies drag Account Health down.Amazon's 24-hour SLA is unforgiving. A handful of late replies in a quarter is enough to dent the rating you spent years building.
How Tideline handles it
The same three pains, the same overnight loop.
One agent, three surfaces. You approve; you don't write.
- Drift watcher flags ACOS creep overnight.Sponsored Products and Sponsored Brands bids are re-read against your target TACoS. Any campaign drifting past the guardrail lands in your digest before the planner opens it.
- FBA reorder drafts pulled from real velocity.Sell-through and lead-time feed an inventory model. Restock POs are drafted and queued in Rules — you approve the order, you don't write it.
- Drafted buyer-message replies in your voice.Trained on three of your past replies, the agent composes a response for every new buyer message and parks it in Inbox — pre-approved tone, ready to send before the SLA clock runs out.
Early sellers using Tideline overnight reclaimed an average of 6.2 hours a week from their Amazon operations — and stopped the Account Health warnings that used to land on Monday.
